Astronomy News For March 2024: Eclipses and other rare Astronomical events.

I assume by now everyone out there has heard about the Solar Eclipse that is going to occur on April the eighth. That day the Moon will cross in front of the Sun completely blocking out the Sun’s light in the middle of the day. The celestial event will draw a line of totality across the North American continent traversing Mexico before passing through 13 states of the US with the show finally ending in the maritime provinces of Canada.

I’ve had my eclipse plans made for sometime now. I’ve got plane tickets and hotel reservations in a small town in Texas just to the east of Dallas. I won’t have to move an inch to see a full four minutes of totality, weather permitting that is. That’s always the big question with any rare astronomical event, whether it’s an eclipse or a transit or an occultation, will the weather be good enough so that you can see? So wish me luck and I’ll tell you all about it when I get back. (See my post of 24 August 2017 about the eclipse of 2017.)

Before I move on to my next story a word of warning about looking directly at the Sun at any time, not just during an eclipse. Yes, I know you’ve heard this all before, nevertheless get a good pair of eclipse glasses before April 8th and BE SURE TO USE THEM! I’m certain by now you’re as tired as I am about hearing the warnings but you’d be surprised at just how many people ignore those warnings no matter how many times they hear them. So, please get a good pair of eclipse glasses and use them when viewing the eclipse. By the way, the Sun is interesting to look at, WITH GLASSES, even when there’s no eclipse.

It takes a really stupid person to look directly at the Sun anytime, even during an eclipse. (Credit: NBC)

Some astronomical events last a little longer than an eclipse however, giving an observer chances on several nights to see it, and one of those may happen later on this year. The star system designated as T Coronae Borealis (T CrB) is known to astronomers as a repeating nova, that is a star system that periodically increases in brightness by hundreds or even thousands of times for short periods of time, usually around a month. Now we’re not talking about a supernova here, you know those massive stars that can end their brief lives in huge explosions that can outshine their entire galaxy for a month or so. Such stars can only explode once and then leave behind either a neutron star or a black hole. (See my post of 26 May 2021 for more information on Supernovas) Ordinary nova may not be as spectacular but some nova can repeat their brilliant displays.

The T Coronae Borealis system consists of a white dwarf star that is stealing material from its red giant companion. Eventually that material builds up on the white dwarf’s surface until it erupts as a nova explosion. (Credit: BBC Sky at night Magazine)

 T Coronae Borealis is a double star system that lies about 3,000 light years away in the constellation Coronae Borealis or the Northern Crown. The system consists of a white dwarf star that is closely orbited by a red giant. The two stars are in fact so close that the white dwarf is stealing material from the outer envelopes of it companion. Eventually enough matter falls onto the surface of the white dwarf to trigger a fusion eruption, causing the dwarf to shine thousands of times brighter, for as long as the eruption lasts.

T Coronae Borealis is one of only five known periodic novas in our galaxy and has been observed to erupt every 80 years for the last several centuries. The last time the system went nova was back in 1948 so it’s about due. The best estimate is that the system will erupt sometime between now and September, but of course it’s always hard to make accurate estimates about something that is happening 3,000 light years away.

Normally T Coronae Borealis shines at a magnitude of +10, far to dim to be seen with the naked eye, even with really dark skies our human vision cannot see anything higher than a +6. As I said however as a nova the star could shine thousands of times brighter, reaching up to perhaps a +2, about the same level of brightness as Polaris the north star and therefore quite visible, even with city lights. And T Coronae Borealis should remain that bright for at least a week giving everyone in the northern hemisphere at least several chances to see this rare event.

You can watch Television or you can go out and look at the most awesome spectacle there is to see. Even without a rare event like and eclipse or nova, the Universe just can’t be beat. (Credit: Scout Life Magazine)

Speaking of supernovas the last such giant event in our galaxy happened back in 1987 when a star in the Large Magellanic Cloud, a satellite galaxy to our Milky Way, exploded. SN 1987A  as it is known was the closest supernova to Earth since the time of Kepler back in the late 17th century and the first, and so far only, supernova for which we actually have a picture of the star before it exploded. (Again see my post of 26 May 2021))

Now when a star goes supernova the outer layers of the star are ejected out into the interstellar medium seeding that medium with the heavier elements that had been generated in the star. The star’s inner core however collapses inward becoming either a neutron star or a black hole.

The intense magnetic field of a neutron star can cause it to emit strong radio waves making it appear to pulse like a lighthouse. Such ‘pulsars’ are well known from supernova remnants like the Crab Nebula. (Credit: NASA)

Now ever since the explosion of SN1987A dissipated astronomers have been searching for any sign of the compact object that was left behind. Astronomers know of many such objects known as pulsars like the one at the heart of the Crab Nebula supernova remnant. Thirty-five years of searching however failed to find any trace of whatever was left of the star that became SN1987A.

The only supernova for which we have an image before it exploded the progenitor star of SN1987a is shown in the right image while the left image shows the star at the peak of its brightness. (Credit: SpringerLink)

Until now, now new observations by the James Webb Space Telescope (JWST) have detected light coming from argon and sulfur atoms surrounding a neutron star at the heart of the supernova remnant. The kind of light Webb detected indicates that the atoms had been electrically charged or ionized by the intense radiation from the neutron star. Although not a direct detection of the neutron star astronomers are calling it a ‘fingerprint’ and it is certainly the best evidence so far.

In this way astronomers have found the smoking gun of the neutron star at the heart of the supernova debris. (Credit: Business Insider)

Proving once again that ‘The Greatest Show on Earth’ is actually not on our planet but in the skies above our heads.

Archaeology News for February 2024:

Back around one hundred years ago it was thought that the story of civilization could basically be told in approximately a linear fashion. Agriculture in the eastern Mediterranean gave rise to the cities of Mesopotamia and Egypt. Civilization then moved westward to first Greece, then Rome leading finally to Germany, France and Britain. There were a few outliers of course, mysterious cultures in China or Meso-America but really the main thrust of human progress was westward across the top of the Mediterranean basin.

We Europeans still like to maintain that ‘civilization’ really started with the Greeks. O’k the Egyptians were kinda like a prelude but it was really the Greeks that count! (Credit: The Mind Attic)

Today we know better. Hundreds of discoveries from excavations around the world have shown us that as long ago as 30,000 years or even earlier, wherever human beings settled they began to develop distinct cultures. In today’s post I’ll be discussing two examples of this, one is the discovery of an entirely new and unknown civilization that flourished in the Amazon jungle some 2,000 years ago but I’ll begin with a study showing that long before the classical Greek period there already were distinct and sophisticated cultures in Europe.

The discovery in America of civilizations that had no connection of any kind to old world cultures came a something of a shock. (Credit: Context Travel)

The people who lived in Europe during the Ice Ages are often depicted as ‘Cave Men’, Neanderthals, barely surviving in a harsh environment with nothing but stone tools and wooden clubs. However by around 34,000 years ago the Neanderthals were gone and the Homo sapiens who replaced them were entering the Neolithic or New Stone Age, a period of increased material culture.

From the first evidence of Stone Age people living in Europe the Cave Man has often been portrayed as nothing more than a brutish clown. (Credit: Shutterstock)

The people in Europe at that time have been given the name Gravettian culture and who lived right across Europe from the steppes of Russia to the Iberian Peninsula. The British Isles and Scandinavia were covered in Ice at this time so it’s not thought that the Gravettians ever settled there. Although these people remained hunter gatherers they also began making their clothes, needles for sewing have been found at their sites, carved small human figurines, know as Venuses because they were mostly large-breasted female figures, and they made extensive use of jewelry. By the way, we have no idea what these people called themselves, the name Gravettian comes from the name of the ‘Type Site’ in France at Le Gravette against which the other 133 known Gravettian sites are compared.

From about 30,000 to 20,000 years ago the Gravettian culture was widespread across northern and western Europe. Bear in mind the British Isles and Scandinavia were under ice at this time. (Credit: OpenEdition Journals)
The Gravettian culture is probably best known for the numerous small, carved figurines called ‘Stone Age Venus’. The emphasis on a woman’s sexual characteristics is obvious. (Credit: Onlinehome.us)

Because their tools, artwork and jewelry were roughly similar it was thought that the Gravettians represented a single, widespread culture. Minor differences were thought to be due to local conditions. The people living near a seashore for example might make greater use of seashells while those living in the interior would make greater use of animal bones and teeth. Still, on the whole the Gravettians were a single culture.

Throughout their range the Gravettian people often wore beaded jewelry headcaps. Recent DNA analysis also indicates that they were probably fairly dark skinned. (Credit: EurekAlert!)

That view has now been brought into serious question by a new study published in the journal Nature Human Behavior by doctoral student Jack Baker at the University of Bordeaux. What Baker did was to survey all of the literature concerning Gravettian sites dating back to the mid-1800s. He then classified the thousands of beads detailed in those papers that were used in jewelry into 13 types based upon what material they were made from, clam shell or snail shell, deer tooth or fox tooth, along with other design elements.

Literally thousands of many different kinds of objects, used as beads for decoration, have been unearthed at Gravettian sites. (Credit: Ancient Origins)

He then examined the classification patterns that he found at the different Gravettian sites, compared them to neighboring sites and discovered that, judging by their jewelry the Gravettians possessed nine distinct cultures. Baker theorizes that the differences in jewelry may have allowed different Gravettian ‘clans’ to recognize ‘friend from foe’ although he also thinks that at the borders between cultures a sharing of jewelry may have taken place. All of which shows that, even in Europe there was a lot more to building civilization that we ever thought.

Did the Gravettians use fashion as a means of identifying friend from foe? We certainly do that today, so when did this particular form of prejudice start? (Credit: RootsWeb – www.iabrno.cz)

The second discovery relates to the civilizations of Meso-America, extending and highlighting the uniqueness of those cultures when compared to the western Greco-Roman world. It also enhances our understanding of the pre-Colombian civilizations that inhabited the Amazon River basin, cultures whose very existence were unknown just thirty years ago. Since then however considerable evidence of several complex societies has been discovered from Bolivia through to the mouth of the Amazon, societies that date back as much as 1,500 years. (See my Post of 4 April 2018)

Recent discoveries have shown that even in the densest jungle the Amazon river was home to an extensive and sophisticated culture. (Credit: Scientific American)

The new discovery, announced in the journal Science not only extends the size of the Amazon culture into the eastern portion of the country of Ecuador but it also extends it back in time to at least 2,500 years ago based the excavations carried out so far. As with many of the latest archaeological discoveries the finds in Ecuador’s Upano valley were first uncovered by an airborne survey of the region using LiDAR, the laser version of radar.

What the survey revealed was over 6,000 platform like earthen mounds averaging 20m by 10m and 2-3m in height and the platforms were normally arranged in groups of 3-6. Lead researcher Professor Stephen Rostain of the National Centre for Scientific Research in France theorizes that each platform could serve like a yard for a single family dwelling although some platforms were large enough for extended family to live there, or even contain communal or ritual structures. These groups of platforms were then connected by a series of extremely straight roads, so straight, considering the hilly terrain that Professor Rostain thinks there must have been some reason, perhaps religious, for making them so straight.

A few excavations have now been carried out in the Upano valley but many sites remain as we learn more about this unknown civilization. (Credit: CNN)

So far only a few of the platforms have been excavated so we can only estimate that the Upano valley civilization began around 2,500 years ago and lasted just about 1,000 years. With 6,000 platforms remaining unexamined there’s a lot to be learned, and a lot of work to be done.

The more archaeologists discover about the many civilizations spread around the world the more it becomes obvious that building civilizations is not confined to any particular region of ethnic group. It’s just something human beings do.

We did it, not only was 2023 the hottest year ever recorded for our planet but because January 2024 was also hot the Earth surpassed the 1.5º C above pre-industrial levels for an entire year. 

The bad news came shortly after New Year’s with the announcement by climate scientists that the year 2023 was on average the warmest year ever recorded for our planet, surpassing the previous record holder 2016 by nearly a tenth of a degree Celsius. While a 0.1ºC increase may not sound like a great deal that happening for the entire planet over an entire year represents an enormous amount of extra heat in the atmosphere.

2023 was not only the hottest year ever recorded it broke the previous record by an astounding amount. Also, notice how the ten hottest years ever have all been in the last ten years!!! (Credit: News Center Maine)

The final tally for 2023 was an increase of 1.48ºC above pre-industrial temperatures; just slightly below the 1.5ºC increase that climatologists have been warning for decades will bring on ever greater climate disasters. Worst still, if you consider the 12 month period from the first of February 2023 to the 31 of January 2024 we broke that 1.5ºC barrier.

Scientists have been warning us for decades that climate change starts to get real bad when we go over 1.5 degrees C above pre-industrial levels. Well, we’re past that now and can 2 degrees be far away? (Credit: CBC)

Meteorologists point out that the strong El Nino pacific weather pattern that developed around May in 2023 added to the historic heat levels measured from June to December, and now January 2024 as well. That El Nino is expected to continue for some time in 2024 so it is perfectly possible that 2024 may wind up being even hotter than 2023. So we are now getting a taste of a world above that 1.5ºC, a world with severe weather year round, from tornadoes during the winter months to endless wildfires, floodings etc.etc. The question is, are people paying attention.

The Pacific phenomenon known as El Nino can effect weather patterns around the World. (Credit: SciJinks)

I’m afraid that the answer to that question is no. The climate deniers are still out there, still trying to convince people that civilization will collapse if we don’t keep on burning coal, oil and natural gas. There has been a shift in their arguments however. With the actual measured data clearly showing that the last ten years, 2014 to 2023, were the hottest ten years ever recorded the petroleum industry and its apologists are no longer trying to assert that global warming simply isn’t happening, or at least that human activity isn’t to blame for it. No, instead they are now trying to convince people that, while climate change may be happening, it’s really not going to be that bad and besides there’s nothing we can do to stop it.

And if all of you Republicans who believe climate change is a Chinese hoax will clap your hands the bad weather will just go away! (Credit: Los Angeles Times)

This ‘New Denialism’ is showing up in ever increasing numbers of YouTube videos, facebook posts, and other forms of social media. This new denialism is characterized by attacks on possible solutions to global warming along with the worldwide climate movement. False claims that Solar and Wind energy don’t work and that climate scientists are either alarmists or corrupt, I’ll have more to say about that later, have increased to 70% of anti-climate videos on YouTube while actual claims that climate change isn’t happening have dropped to only 14%. Some of the claims come close to hysteria, ‘They’re trying to take away your cars and stoves’ for example or that wind turbines cause cancer.  For the most part however the deniers claim that clean, green energy will simply not work and attempts to reduce green house gas emissions will destroy the economy.

Of course what they are really saying is that the economy of the billionaires and millionaires will be harmed if we get rid of fossil fuels! (Credit: Aurora Sentinel)

One recent claim even asserted that the sonar surveys carried out in preparation for the construction of wind farms along the US Atlantic coastline were causing whales and dolphins to beach themselves. This is despite the fact that the beachings occurred more than nine months after the surveys had been completed. Republican State Legislators in the State of New Jersey even tried to get a bill passed to ‘Save the Whales’ by halting further development work on the wind farms. I’m certain it’s the first time any of them ever cared about Whales. 

In the last three months 24 whales and dolphins have washed up on the US East Coast. That’s a tragedy but it’s also 9 months after the sonar surveys for offshore winds farms were completed! (Credit: The New York Times)

At the same time other bills and zoning regulations are also cropping up across the country that are designed to restrict if not halt the construction of clean energy wind and solar energy installations. As many as 15% of the counties in the US have passed bans or moratoriums that effectively make it impossible for anyone to construct a large scale wind or solar farm, even on their own property. Worst still, many of the places that are banning green energy projects are the best places for such projects. Think about it, Texas obviously gets a lot more sunlight than Maine, but Texas is an oil state and the politicians in Texas would rather force people to keep burning fossil fuels than allow anyone to build solar power projects. That’s despite the economic benefits from the money for the energy produced along with all the good paying green energy jobs. It’s an old story, many of the people who oppose wind and solar projects actually accept the need for green energy to combat climate change, they just don’t want them in their backyard.

Currently a large majority of Americans feel that we should increase our energy production through the use of wind and solar power, but why does it have to be near me!!!!! (Credit: National Geographic Society)

After all of that bad news I do have a small piece of good news. The climate deniers on the web have many times not only lied about climate science but the scientists who are trying to warn us about the climate disasters we now face. These falsehoods have many times gone far beyond criticizing the work the scientists are doing to include allegations that the scientists are taking bribes for falsifying climate data and even claims that the scientists are guilty of crimes, even sex offenses.

Well one noted climate scientist decided to fight back. Michael Mann is a highly regarded climatologist at the University of Pennsylvania here in Philadelphia who has long been in the forefront of the fight to convince the public of the serious threat that greenhouse gasses pose. It was back in 1998 that Doctor Mann published his ‘Hockey Stick’ graph of global temperatures over the past several hundred years.

The famous ‘Hickey Stick’ graph of global temperatures over the last thousand years. For the first approximately 800 years the temperature was slowly getting colder, we’re still really in an ‘Ice Age’ after all. In the last 150 years however global temps have gone up three times as much as they’d gone down in the previous 800 years. (Credit:

Dr. Mann had used his research in tree rings, coral reefs and ice cores to show that global temperatures had been relatively stable for centuries before the start of the industrial revolution but that ever since humanity had begun to burn large quantities of fossil fuels global temperatures had spiked dramatically. The graph of that increase was said to resemble a hockey stick, laid on the ground with its blade pointing up, hence the name. That graph became famous and made Mann the target of right-wing critics more interested in defending fossil fuels than the truth or a dedicated scientist’s reputation.

A jury may have found that climate deniers defamed scientist Michael Mann (r) but of course the plaintiffs are appealing that judgement. (Credit: YouTube)

Two conservative writers in particular, Rand Simberg of the Competitive Enterprise Institute and Mark Steyn of the National Review went so far that in 2012 Professor Mann sued them for defamation. It took twelve years of legal wrangling but in early February a jury in Superior Court for the District of Columbia finally agreed with Mann and awarded the climatologist $1 Million in punitive damages. Of course both defendants have announced that they will be appealing the decision so this case isn’t over yet. Still it demonstrates that those people, not just scientists but everyone who is concerned for our planet, can and should stand up to the bullies who ignore the harm they are doing to the world so long as they can make a quick buck.

Space News for February 2024

There’s plenty to talk about this month in Space. For both manned and unmanned spaceflight there’s good news and bad news so let’s start with manned spaceflight first.

Manned spaceflight began with the flight of Yuri Gagarin in 1961. His single orbit of the Earth made him the ‘First Man in Space’. (Credit: ThoughtCo)

The good news of course is the successful launch on January 18th of the Axiom-3 (Ax-3) private mission to the International Space Station (ISS). Although the mission is a private one the crew are not millionaire tourists, they are astronauts representing four different nations. Mission Commander Michael Lopez-Alegria is a dual US-Spanish citizen who has previous flown in space with NASA. The other three crewmen are all space novices with Walter Villadei of Italy serving as Pilot along with Marcus Wandt of Sweden and Alper Gezeravci of Turkey as mission specialists. Astronaut Gezeravci represents Turkey’s first astronaut.

After docking at the ISS on January 20th the four astronauts spent two weeks performing experiments before returning to Earth on their Dragon capsule. The Ax-3 mission is Space X’s twelfth manned mission and as I’ve said before Space X is making the whole process of traveling to Low Earth Orbit (LEO) a routine affair. While the return of the Ax-3 mission was delayed by two days owing to bad weather at the landing zone in the Gulf of Mexico off of Pensacola, Florida the actual re-entry was uneventful, the four astronauts splashing down on February the ninth.

The Ax-3 capsule floats peacefully in the waters off of Florida while awaiting recovery by Space-X personnel. The whole operation of traveling into space is becoming just as uneventful, which is the whole idea! (Credit: Orlando Sentinel)

That’s the whole point of the Space X – Axiom collaboration. Using Space X’s reusable Falcon 9 rocket and Dragon Capsule the cost of space travel is steadily coming down, the four nations involved in Ax-3 mission each paid $55 million dollars to send their astronauts into orbit. because of that small countries and corporations can now send scientists and engineers into LOE to do research aboard a new generation of space stations, and the cheaper it gets the more that will do so.

Getting beyond LOE is another matter however. Only one nation, the US has ever succeeded in taking astronauts to Earth escape velocity and the last time they did that was back in 1972. Back in December of 2022 NASA finally succeeded in sending an unmanned, but man capable Orion capsule on a journey around the Moon on its Artemis 1 mission. At that time it was anticipated that the first manned mission, Artemis 2 another trip around the Moon, would take place later this year.

That mission has now been delayed however. On January 9th NASA announced that the Artemis 2 mission would take place No Earlier Than (NET) September of 2025. That schedule change will then affect all subsequent missions in the Artemis program. Artemis 3, the first mission to attempt a landing, will now take place NET late 2026 and most likely will be pushed back into 2027.

In just a few years one of these landers will be taking humans back to the Moon. Space X on the left or Blue Origin on the right. Which is still up in the air at the moment. (Credit: Tesmanian)

The major reason for the delay is the Orion capsule’s heat shield, which during reentry on the Artemis 1 mission did not behave in a ‘nominal’ fashion. Finding out exactly what happened is taking longer than expected and with several additions technical issues as well it was decided to announce the delays now.

When a spacecraft re-enters our atmosphere it is traveling at thousands of kilometers per hour. Friction causes the capsule to slow down but all of the heat generated by that friction has to be dissipated by a heat shield. (Credit: All About Space)

The delay in the Artemis missions does not mean that the Moon is lonely however. In January there were two separate attempts at landing a robotic probe on the Lunar surface and again with mixed results. The first to launch was the Peregrine probe that represented the first try at a landing on the Moon by a private corporation; Pittsburgh based Astrobotic Corporation. Sounds a bit like the Ax-3 mission doesn’t it. Similarly to Axiom Space, the idea in the Peregrine lander was that countries or corporations could pay to put an instrument or experiment onboard Peregrine, which Astrobotic would then launch to the Moon.

The launch of the Peregrine Moon lander went well. The first ever mission for the new Vulcan rocket was flawless. The lander itself didn’t work so well however. (Credit: Astrobotic Technology)

Peregrine started out with an auspicious launch, the first ever for the new Vulcan rocket from United Launch Alliance (ULA). Vulcan performed well, lifting off from Kennedy Space Center and putting Peregrine into a trajectory for the Moon. However, almost immediately after separating from it’s launch vehicle the probe suffered a fuel leak that spelled disaster for the 1.2 tonne lander. Peregrine never succeeded in leaving Earth orbit and in fact about a week after launch the probe fell back into Earth’s atmosphere and burned up.

This did not happen. The Peregrine lander failed to even leave Earth orbit and fell back into the atmosphere after just a few days in space. (Credit: New Atlas)

The Japanese space agency JAXA was a bit luckier with its Smart Lander for Investigating the Moon or SLIM lunar probe. The landing on the Moon went extremely well with SLIM making the most precise touchdown ever on the Lunar surface, within about 100m of it’s intended position.

Almost immediately however the engineers in Japan noticed that the power levels in the lander’s batteries were dropping rapidly, the craft’s solar arrays were not providing any power to recharge them. Acting quickly the engineers downloaded every image, every bit of data they could from SLIM. Then, about three hours after touchdown on the Moon’s surface the lander was shut down to conserve the last 12% of battery power remaining.

The launch went well and the landing was almost exactly where it was intended but SLIM is upside down! In this position its solar panels are unable to generate full power and it’s questionable how long the lander can continue to operate. (Credit: Reuters)

After several days of investigating what happened the engineers at JAXA realized that the spacecraft had somehow landed on its head, it was upside down on the Lunar surface. In that position its solar panels weren’t getting enough of the Sun’s light to fully power the probe causing the drop in electrical power.

With no clouds to obscure the Sun solar power on the Moon is even more efficient than here on Earth. But you do have to point your solar panels at the Sun. (Credit: IEEE Spectrum)

The Sun does move across the sky during the Lunar day however and on the 28th of January SLIM’s solar arrays began to produce enough power to allow the engineers in Japan to bring it back to life, for a while at least. The long Lunar night is coming during which time the probe will have to depend on whatever energy is stored it its batteries, so whether SLIM can survive to continue its mission is questionable.

Whether on the Moon or here on Earth a dead battery is never a good thing. (Credit: Interstate Batteries)

That’s the reality of operating in space however; there are successes, failures and sometimes even partial successes. Like a child learning to walk we are learning how to live and work in space, you have to expect an occasional fall now and then.

People have had some crazy ideas about how we’re live in space but what’s not crazy is the idea that before too long we will be doing so! (Credit: IFL Science)

One last sad note, NASA’s venerable Voyager 1 spaceprobe is in trouble. The probe, which was launched way back in 1977 and is now 24 billion kilometers from Earth is the farthest man-made object ever and has for the last 10 years been sending back data about conditions in interstellar space.

It must be lonely out there. Voyager 1 has now officially left our Solar System. Until 2 months ago it was still sending back data about the conditions in interstellar space but unless NASA engineers can figure out what’s wrong with it the venerable probe could be lost forever. (Credit: Interesting Engineering)

The trouble started back in November when the data sent back from Voyager suddenly became a repeated pattern of meaningless 1’s and 0’s before turning into what’s known as a ‘carrier tone’, nothing more than a steady hum that at least let’s engineers at NASA know the probe is still there. After several months of investigation the engineers are convinced that the problem lies in the spacecraft’s Flight Data Subsystem and could be something as simply as a single corrupted bit in the memory.

Sometimes even just a single corrupted bit in a program is enough to cause everything to go haywire. (Credit: ResearchGate)

Fixing Voyager’s problem is going to be a very difficult problem, if it can be done at all. The probe is so far away that it takes 45 hours to send a radio signal and get a response back, and right now Voyager isn’t responding. Also, the spacecraft is more than 45 years old, making it older than some of the engineers trying to fix it.

At least when you try to fix an old car you have the car itself in front of you. Voyager 1 is now 24 billion kilometers away. Try fixing that! (Credit: YouTube)

Now Voyager 2 is still transmitting, sending back data from outside our Solar System. Nevertheless, sooner or later we are going to have to accept the loss of both Voyager space probes, let’s just hope it’s not yet!

Book Review: ‘Deaths of Despair and the Future of Capitalism’ by Anne Case and Angus Deaton

We all are aware of how the economic conditions in this country have changed over the last 30-40 years. Where once assembly line manufacturing was the main driver of the GDP here in the US now it’s high-tech engineering, microchips and software, industries that require far fewer employees but those with greater education. These changes in the economy have brought with them demographic changes as millions of high school graduates lost well paying jobs with benefits while people with a college degree were in ever greater demand, and therefore saw at least a modest increase in their income and wealth.

One unexpected outcome of these economic changes is the effect on the overall health of the American people caused by a massive growth in ‘Deaths of Despair’ that is drug overdoses, suicide and alcoholism. ‘Deaths of Despair and the Future of Capitalism’ by Anne Case and Angus Deaton examines the increase in drug overdoses, suicide and alcoholism from both an economic and sociological perspective, both authors are retired professors of economics at Princeton University and Professor Deaton was awarded the Nobel Prize in Economics in 2016.

While the difference in salary between College graduates and High School graduates may be understandable the difference in Life Expectancy is harder to grasp. That’s the thesis of ‘Deaths of Despair’ by Anne Case and Angus Deaton. (Credit: World Socialist Web Site)

‘Deaths of Despair’ begins by demonstrating just how large a problem drug overdoses, suicides and alcoholism have become. In fact these social diseases were actually causing a decline in the average life expectancy of Americans before the Covid-19 pandemic. The book then goes on the show how these ‘Deaths of Despair’ reside almost exclusively in the white male population without a college degree, exactly the part of the population that has seen the most economic turmoil in the last 40 years. That turmoil being the driving force behind the despair a large part of our population now feels.

The central portion of the book is a detailed examination of how the economy has changed over the last 40 years and why damage generated by those changes seem to have almost targeted white males with only a high school education or less. In addition to the lost of income in going from a well paid factory job with benefits to a low paid service job with few benefits ‘Deaths of Despair’ also considers such factors as the loss of pride and community that accompanied the switch from buildings cars at General Motors to flipping burgers at McDonald’s. At the same time social changes of the last few decades added to the despair of white, blue-collar males. The advancement of both woman and minorities only increased the feeling of lost prestige and privilege.

Then, at just the time when these changes were generating despondency within a large section of the population the pharmaceutical industry began a campaign of selling synthetic, non-addictive opioids as a cure all for any kind of pain. Of course we now know that OxyContin and its relatives are actually highly addictive and can even act as gateway drugs to worse opioids like heroin and fentanyl. The callous greed of the drug companies who made billions by turning millions of Americans into addicts, or in all too many cases corpses is graphically detailed.

As a large portion of the American working class saw their once comfortable life disappearing many of them got caught up in the opioid epidemic. Notice how the number of overdoses among men is nearly twice that among women. (Credit: Wikipedia)
In ‘Deaths of Despair’ the authors cover the effects of suicide, alcoholism and the opioid epidemic on those with less than a college education. However they completely miss the equally tragic effect of education on smoking rates with high school graduates smoking, and dying because of smoking at more than twice the rate of those with a college degree. (Credit: Medical Express)

In the final section of ‘Deaths of Despair’ the authors give their recommendations on how to rebalance the economic system so as to better serve all Americans not just the top 1% or even the better educated. To be honest however the authors are academics and as such they are cautious in their suggestions.

While since 1975 many nations have seen the top 1% grab a larger share of the wealth here in the US that increase is significantly greater. Leaving that much less for the average person. (Credit: Wikipedia)

The most fundamental change put forward in ‘Deaths of Despair’ is a complete reform of the healthcare system in the US, which the authors contend does not even meet the criteria of a true capitalist marketplace. Not only are the drug companies and health insurance corporations criticized in detail but hospitals, ambulance services and even doctor’s associations are shown to be guilty of acting as an Oligopoly. (An Oligopoly is a small group of merchants or corporations that by colluding together rather than competing virtually become a monopoly, raising prices while using their power to destroy any competitors) According to the Authors this is why Americans spend more for their healthcare than any other nation while both life expectancy in the US and approval of our healthcare system rank amongst the lowest for any industrialized, wealthy country. In ‘Deaths of Despair’ the authors estimate that a through reform of the health care system could free up as much a a trillion dollars a year in GDP that could be used to maintain our infrastructure, improve education etc, etc, etc.

As a fraction of our countries wealth (GDP) the costs of Health Care have more than tripled since 1960! Are we living three times as long or has the Health Care Industry simply become inefficient and wasteful? (Credit: Kaiser Family Foundation)

While reform of the healthcare system is the author’s main recommendation they also suggest a stronger social safety net for those who lose their jobs due to changes in the economic system, the safety net must be of longer duration and include retraining for newer jobs. On the other hand they do not recommend simply raising taxes on the wealthy as a means of fixing income inequality nor do they endorse programs like the Universal Basic Income (UBI).

A dream of Socialists since the 19th century Universal Basic Income would make certain that no one falls into poverty despite lack of education, layoffs, sickness or any other circumstance. Conservatives counter that it simply promotes laziness. (Credit: The Nation)

Now, back in May of 2019 I reviewed the book ‘Dying of Whiteness’ by Jonathan M. Metzl, see my post of 5 May 2019, which covers much the same subject as’ Deaths of Despair’. Mr. Metzl however was a state health official while Professors Case and Deaton are among the world’s leading economists so there is a very different perspective in the two books, to my mind in a way that they compliment each other.

So while I do highly recommend  ‘Deaths of Despair and the Future of Capitalism’ I do so with the proviso that it is a very technical book written by scholars who are among the best in their profession. Those readers who really want to understand the complexities of our current situation, both economic and political will gain a great deal from it.

Two stories from Nature about the primary ways animals interact with each other, communication and sex.

Every individual from nearly every species of animal must from time to time interact with other members of its own species. The most important reason for such contacts is surely procreation but there are countless others such as safety in numbers, hunting in packs or even just agreeing upon separate territories so as to minimize the number of interactions. In all of these contacts there must be some form of communication in order to facilitate the outcome of the meeting.

We humans of course have the best, most versatile form of communication, language but we know that the howling of monkeys, the songs of birds and the barking of dogs are simpler, courser forms of language. At the same time we wonder if some of nature’s other most intelligent species, dolphins or chimpanzees for example, may have languages approaching ours in complexity. Over the past fifty years or so there have been numerous studies to try to ‘talk with the animals’ as Doctor Doolittle would say.

Recently an experiment in communicating with humpback whales has been carried out by a group of researchers from the University of California at Davis, the Alaska Whale Foundation along with the SETI Institute. Humpbacks are well known to communicate with each other using long songs that seem to repeat themselves with slight variations and that can travel for thousands of kilometers in the ocean.

Researchers with UC Davis, the Alaska Whale Foundation and SETI succeeded in carrying on a ‘conversation’ with a wild Humpback Whale for 20 minutes. We’re not quite certain what the conversation was about but the whale seemed to enjoy it. (Credit: YouTube)

What the team did was to take a boat out to an area of the ocean where humpbacks were known to be and played a recording of a humpback song that was well established as a form of greeting. The humans then waited for a response from one of the whales. They didn’t have to wait for long as a humpback who had been given the name of Twain not only replied to the call but approached the boat and began circling it.

No, we haven’t gotten there just yet, but it sounds like an interesting book! (Credit: Amazon.com)

The researchers then began playing other recorded whale calls and each time Twain replied with a different call of his own. Now the scientists had only the vaguest idea of what their calls actually meant in the humpback language, let alone what Twain’s replies meant but they still managed to continue the ‘conversation’ for about twenty minutes.

Considering all the problems we have communicating with other humans it’s gonna take a while before we’re really talking to animals. (Credit: English Tips)

While a twenty-minute exchange of only half understood messages can hardly be considered a ‘communications breakthrough’ it is nevertheless data that can be analyzed by the mathematical principles known as information theory. And with each additional such encounter scientists will learn a little bit more about how to communicate with the other intelligent creatures that share our world with us.

Another interesting point about the study is the inclusion of the SETI or Search for Extra-Terrestrial Intelligence Institute, an organization dedicated to seeking out intelligent life elsewhere in the Universe, not here on Earth. However the people at SETI recognize that learning how to communicate, or even just being able to recognize an attempt at communication with non-human life here on Earth will help them to better find and contact alien intelligences. Slowly we humans are coming to understand the other intelligences here on Earth and one day soon we’ll be having real conversations with them.

The SETI institute is usually concerned with communicating with Extra-Terrestrials but they are also interested in communicating with non-human life forms here on Earth. (Credit: The Indian Express)

However, as I said above the most important reason living creatures have for interacting with members of their own species is mating, producing offspring to keep the species going, sex! Now we all know that the many different species here on Earth have quite a variety of different ways to have sex. Some species of fish for example gather in large numbers of both genders and then just release both their eggs and sperm into the water knowing that most of the eggs will get fertilized by somebody’s sperm. Many plants actually use an intermediary like a bee to carry their pollen from one flower to another so that fertilization can occur. The only set rule of mating is that, if it works it works.

When coral spawn they simply release their eggs and sperm into the water. Some of the eggs get fertilized, many don’t. It works for them however, they’ve been here at least half a billion years. (Credit: CoralGardening)

It was thought that all mammals basically had sex the same way we humans do. The male’s penis penetrates the female’s vagina where it releases the male’s sperm in order to fertilize the female’s egg. Certainly dogs, horses, whales and even egg laying mammals like the platypus do it that way.

It was thought that all mammals, even dolphins and whales, mated pretty much the same way that we humans do. The male penetrates the female leaving his sperm inside her to fertilize her eggs. (Credit: YouTube)

Now however a new study from the journal Current Biology has called that assumption into question for one large group of mammals, the bats, based upon videos taken in a church steeple in the Netherlands. The species of bat in the study is known as serotine bats who are native to a wide area of both Europe and Asia. Since bats are nocturnal and often live in hard to access places not a great deal is known about their mating habits in general and the serotine bats in particular were considered mysterious. You see the penis of the male serotine bat was simply too large to fit inside the female’s vagina!

Unlike mammals, when most species of birds mate there is no penetration by the male. Instead he simply spits his sperm at her vagina and enough of it gets in to cause fertilization. (Credit: Shutterstock)

So researchers, led by Dr. Nicholas Fasel filmed hundreds of hours of the bats in the steeple of an Old Dutch church where they succeeded in catching several instances of the bats mating. What they found was that serotine bats mate by simply touching their genitals together in a manner similar to the way most species of birds mate, not mammals. This finding raises the question of whether other bats have sex the same way, quite a few species are known to have oddly shaped if not oversized penises.

In Serotine bats the male’s penis is fully seven times larger than the female’s vagina making what we consider normal copulation difficult if not impossible. The recent study has concluded that Serotine bats copulate in the same fashion as bird’s do. (Credit: Daily Mail)

So if serotine bats mate by just touching their genitals then why do the males have such large penises? Well, Dr. Fasel points out that the female serotine bat has evolved a flap of their leathery wing as a covering for their vagina in order to prevent an unwanted male from being able to mate with them. He theorizes that perhaps the male has evolved his large penis as a means of pushing that flap out of the way. In other words we may be witnessing a literal battle of the sexes in evolution.

The Battle of the sexes is even a standard problem in Game Theory. The best solution is to do something together. (Credit: Springer Link)

All of which shows that when it comes to interactions between members of the same species nature keeps coming up with odd and interesting ways of doing things.

Arno A. Penzias, co-discoverer of the Cosmic Microwave Background (CMB), the first evidence for the Big Bang has died at the age of 90.

Most people I suppose have never heard of Arno A. Penzias, but everyone has heard of the Big Bang Theory, the idea that about 14 billion years ago, give or take a couple hundred million, the entire Universe underwent an unimaginable explosion and the expansion caused by that explosion continues today. Well it was Doctor Penzias, along with his colleague Robert W. Wilson who provided the first actual evidence that the Big Bang really happened.

The story of Doctor Penzias contains within it several of the themes that often occur in both science and human history at large. Arno Penzias was born in 1933 in Munich, Germany to Jewish parents. If you can imagine a worse place and time for a Jewish boy to enter the world, well I can’t. Arno was lucky however for he and his brother were part of a British program that brought 10,000 Jewish children out of Nazi Germany just before World War 2 began. Later Arno’s parents also succeeded in escaping Germany and the whole family arrived in America in 1940. Arno was therefore one of the very large number of talented scientists who came to America and who made their discoveries here after fleeing Nazi tyranny.

Interested in science from an early age Arno first intended to become a chemist but switched majors to Physics while attending the City College of New York. Arno would eventually receive his Ph.D. in 1962. Even before becoming a Doctor however, in 1961 Arno accepted a job on the project that would lead to his greatest discovery.

In the early 1960s Bell Labs in Holmdel, New Jersey was one of the centers for ‘space age’ technology. The transistor had been invented there, as had the Laser. Communications satellites were the next big thing and indeed Telstar; the first communications satellite was built at Bell Labs. The engineers who were designing Telstar needed to know, once their satellite was up in orbit, what kind of radio sources there were in the Universe at large that could cause static interference with Telstar.

That was the job that Arno Penzias and his colleague Robert Wilson were assigned, survey the entire sky at microwave frequencies and catalogue all of the radio sources that could cause problems for communications satellites. To accomplish their task Penzias and Wilson used the brand new Holmdel Horn antenna, especially designed for communicating with satellites and at the time one of the largest radio antennas on Earth. With such a powerful instrument in their hands the two physicists were determined to not just survey and catalogue radio sources, but to study them as well.

In the early days of Radio Astronomy measurements were used to develop contour maps of radio sources like this one of the center of the Milky Way. (Credit: ResearchGate)

As the two men carried out their survey they quickly ran up against an annoying, so they thought, little problem. No matter where they pointed their antenna, no matter when, there was always a persistent background hiss that they couldn’t get rid of. The hiss didn’t come from any source, it was everywhere, so they initially thought it had to be man made noise from something nearby. Working methodically the two men eliminated radar from nearby airports as the cause, noise from many sources coming from nearby New York City even the possibility of radiation from nuclear tests. One of their efforts to eliminate the noise has become something of a anecdote in physics departments. Noticing that several pigeons were nesting inside the big horn antenna they wondered if the bird’s droppings could be the cause of the hiss so they gave the entire horn a through clean out. No good, the noise remained.

In our modern world there are all sorts of things, both natural and man-made, that can generate radio noise that will interfere with communications. (Credit: IQS Directory)

Looking through the literature for some idea as to what could be going on they came across a paper written by physicists George Gamow and Ralph Alpher about how the Big Bang, if it had actually happened, should have left behind a measurable amount of heat, the way a frying pan on your stove stays warm for a while after you turn off the burner. After billions of years Gamow and Alpher calculated that residual heat would now be observable in the microwave region, just where Penzias and Wilson’s hiss was. (For more information on George Gamow and the prediction of the CMB see my post of 30 October 2021.)

Since Gamow and Alpher were teaching in Colorado and Texas respectively Penzias and Wilson decided to contact physicist Robert Dicke at nearby Princeton University. In another of those coincidences that no one could ever imagine Dicke and his students were actually planning on looking for the CMB and were gathering up the equipment they’d need to look for it. As remembered by Nobel Prize winner James Peebles, a graduate student of Dicke’s at that time he was in his mentor’s office when the call came from Wilson. “We’ve been scooped!” Dicke said as he put down the phone.

That was in 1964 and the news of the discovery of the CMB spread quickly turning the subject of cosmology from a few people working on a few ideas to a major study on which thousands of researchers around the world are working. Penzias and Wilson were awarded with the 1978 Nobel Prize for their discovery. The moral of this story is to keep alert, if some unknown factor is effecting your measurements don’t just ignore it, find out what it is. Like Rontgen and the discovery of X-rays, sometimes that unknown factor is more important than the thing you started out trying to study. In both cases the scientists became famous for discovering something they never even planned on looking for.

Penzias and Wilson saw the CMB as a constant everywhere they looked but today’s measurements, from the Planck satellite, show a very small variation in the temperature. These variations form the seeds out of which today’s galaxies and stars would form. (Credit: New Scientist)

Arno A. Penzias died on the 22nd of January at an assisted living facility in San Francisco. His death was due to complications from Alzheimer’s disease. There were a huge number of major scientific discoveries made during the 20th Century; Arno A. Penzias’ discovery that ‘the Universe began, not with a whimper but with Bang’ may have been the biggest.  

Astronomy News for January 2024: Astronomers are finally beginning to learn something about Fast Radio Bursts (FRBs).

We all know that the cosmic zoo has many weird and wild inhabitants. In addition to the familiar stars, planets, moons, asteroids and comets there are quasars, black holes, neutron stars and brown dwarfs to name just a few. One of the least understood types of objects are known as Fast Radio Bursts (FRBs) which were first discovered in 2007. FRBs are exactly what their name implies, extremely powerful radio emissions that only last for a few thousandths of a second.

Galaxies are just one kind of animal in the Cosmic zoo, but still there are many different types of them! Add in the black holes, supernova, pulsars and etc. and you get quite a plethora of different kinds of objects. (Credit: Futurism)

The fact that FRBs only last around a millisecond makes them very hard to study. Think about it; let’s say a radio astronomer is studying the Andromeda galaxy when out of nowhere, bam there’s a burst of radio energy that’s gone before he can react to it. Hopefully the scientist’s instruments have recorded something but there certainly wasn’t time to make any detailed measurements of the FRB.

A Fast Radio Burst (FRB) is exactly what it sounds like, a short but powerful emission of radio waves from somewhere across the Universe. Like a brief flash of light you see out of the corner of your eyes such things are obviously not easy to study. (Credit: Space.com)

For several years it was thought that FRBs were one offs, that is to say whatever object had generated an FRB would never generate another. Just a couple of years ago however the first repeating FRBs were identified and now it is thought that astronomers have identified about 50 repeating FRBs. The question then is whether all FRB sources are actually repeaters, although with different time scales.

Recognizing some FRBs as periodic has allowed radio astronomers to train their instruments on a known repeater and then just wait to catch the full event. Recently this technique has enabled astronomers to catch the furthest ever seen FRB at a distance of about 8 billion light years away. To be able to be heard from such an enormous distance the FRB, which has been given the designation FRB 20220610A, had to pack as much energy as our Sun emits in 30 years into a pulse less that one thousandth of a second.

Although there is a great deal that is still unknown about FRBs a consensus of opinion is growing that FRBs are generated by neutron stars with extremely strong magnetic fields known as magnetic-stars or magnetars. (See my post of 21November 2020 concerning neutron stars) Neutron stars are the remnants of big stars, at least 10 times the mass of our Sun, that have exploded as supernovas., Whatever is left, about the mass of our Sun, is crushed down to a size about 20-40km in diameter, becoming in a sense a big atomic nucleus made almost exclusively of neutrons. Even though astronomers have begun to agree on the source of FRBs however there was still a debate over how magnetars stars generated the radio outbursts, the two leading candidates being either something like a solar flare or some kind of starquake in the magnetar’s surface.

One theory for how FRBs are generated proposes that flares released by highly magnetic neutron stars (Magnetars) collide with matter released from previous flares. Some of the energy of that collision is emitted as intense radio waves. (Credit: CivilsDaily)

Recently a new study by Tomonori Totani and Yuya Tsuzuki at the University of Tokyo’s Department of Astronomy has compared the time and energy distribution of some 7,000 FRBs from those 50 repeating sources to seismic measurements of nearly 6,000 Earthquakes from Japan. What the two found was several similarities between the two sets of data, especially when it came to aftershocks. In summary the similarities were:

1. The probability for an aftershock occurring was 10-50%

2. The probability for an aftershock decreased with time as a power of time.

3. The probability for an aftershock remains constant even as the mean rate of the original FRB changes.

4. There is no correlation between the energies of the main FRB and any aftershocks.

We’re all aware of the power of an Earthquake. Just imagine such a thing happening on a neutron star! (Credit: New Straights Times)

On the other hand the astronomers found no relationship between FRBs and solar flares. This analysis strongly suggests that FRBs are generated by starquakes on the surface of magnetars. If that is true then we may be able to use the data from FRBs to help us better understand these ultra-dense onjects.

Almost beyond imagination is the idea of a quake on an object as massive as our Sun yet as small as a city. (Credit: Scienceline)

Doctors Totani and Tsuzuki intend to continue their analysis, hoping that further measurements from more FRBs may tell us more about FRBs and the weird cosmic wonders that generate them.

Paleontology News for January 2024

Two discoveries from the age of the dinosaurs along with a more recent one that straddles the borderline between paleontology and anthropology headline this post. As usual I begin with the oldest and work forward in time.

In a very real sense the science of paleontology began on England’s south coast, the famous Jurassic Coast. (Credit: Pinterest)

England’s southern coast is one of the most famous and important fossil areas in the world, in many ways that is where the very science of paleontology got it’s start. At the eastern end the ‘White Cliffs of Dover’ are made of chalk from the cretaceous period, indeed the whole cretaceous period is named for the Latin word for chalk because of those cliffs. The west end of England’s south coast is also well know for it’s fossils from the Triassic period, the dawn of the age of the dinosaurs.

The ‘White Cliffs of Dover’ are actually the shells of untold billions of microscopic plankton. In other words one big fossil bed. (Credit: Enjoy Travel)

It’s the middle of the southern shore, the co-called Jurassic coast that includes the Isle of Wight that is most famous for its fossils however. It’s here that during a walk along the water’s edge that fossil enthusiast Phil Jacobs noticed the tip of a snout lying on the ground beneath a cliff. Realizing that the snout must have just eroded out of the cliff face Jacobs secured the bones and quickly got his friend Steve Etches to help him see if there were more of the animal’s bones still in the cliff. Thus they began a difficult and dangerous excavation that took several months but by the end the two fossil hunters had succeeded in finding a 2 meter long skull of a Pliosaur, the apex predator of the Jurassic oceans some 150 million years ago.

Although the fossil still has to be thoroughly studied in detail it appears that the skull is the most complete ever found of a Pliosaur and based upon the size of the skull in life the animal would have been 10-12 meters in length. The jaws contained 130 teeth, long and razor sharp and the muscle attachment points on the skull indicate that the creature could have had a biting force of 33,000 Newtons, twice that of a saltwater crocodile, the strongest bite in the world today, all in all a real sea monster.

And that skull will be revealed to the world in a BBC special, hosted by David Attenborough no less. The special is scheduled for New Year’s day in the UK and hopefully will be seen soon thereafter in the rest of the world. Best of all, Jacobs and Etches are certain that the rest of the animal is still in that cliff awaiting excavation. Maybe the money and notoriety generated by the special will enable them to dig out the rest of this extraordinary beast.

And speaking of apex predators paleontologists at the University of Calgary and the Royal Tyrrell Museum of Paleontology have announced the discovery of a juvenile specimen of Gorgosaurus libratus, a relative of the famous Tyrannosaurus rex, with the contents of its stomach, its last meals intact. The specimen itself is about 75 million years old and is thought to have been between 5 and 7 years old at its death. In life the animal would have weighed some 350 kg, stood as tall as a tall man while measuring more than four meters from its nose to the tip of its tail.

Perhaps not a large as it’s cousin T rex, Gorgosaurus libratus was probably equally as deadly. (Credit: Carnivora)

What makes this specimen so interesting however are the bones found inside the animal’s stomach, four drumsticks from another type of birdlike dinosaur called Citipes, each of whom would have been about the size of a modern turkey. The bones were articulated, in other words they hadn’t been broken up by chewing, and one pair appears to have been more digested than the other so they may be the animal’s last two meals. Also, there is no evidence for the rest of the bodies of the Citipes but it’s unlikely that a meat eater like G libratus wouldn’t have eaten the rest of its prey if it could.

Previous finds of young Tyrannosaurids have indicated that they were actually more slender, more agile and quick-footed than the bone crushing monsterous adults and the G libratus specimen fits in that picture. The animal’s last meal (s) also contributes to that idea because Citipes were rather small and fast animals themselves, so the young G libratus would have had to be a fast predator to catch them. A very different creature from the heavily muscled giants they grew up to be.

Finally today I like to discuss a new study from the Aarhus University in Denmark that lies on the border between paleontology and anthropology. The study considers again the question of what caused the extinction of the large ice-age mammals like mammoths, mastodons, cave bears, Irish elk and etc. As a group these animals are known as the mega-fauna which is defined as any species that weighs more than 44 kg when fully grown. For decades now the debate has raged over whether these species died out because of climate change, the ice ages, or were they hunted to extinction by our ancestors.

Nearly as large and impressive as the dinosaurs they replaced the Mega-Fauna of the ice ages disappeared at just about the time that we humans began spreading around the World. Coincidence????? (Credit: Pinterest)

The study examined DNA from 139 large species still alive today such as elephants, rhinos, oxen, cattle, deer, kangaroos and even our cousins the great apes. What the researchers found was that over the last 800,000 years the populations of large animals had remained fairly stable even while the polar ice caps grew and then receded about every 100,000 years. Then, just about 50,000 years ago the populations of even those species that still survive showed a marked decline, at just the time when mammoths and the others went extinct. If the populations had stayed steady for over 700,000 years of climate change it is very unlikely that climate caused the sudden population loss.

Perhaps the three best known remaining mega-fauna Elephants, Hippos and Rhinos are all in danger of being driven to extinction by human beings. (Credit: Quora)

More than that, the precise timing of the population drop always coincided with the period when archaeology indicates that the first humans entered the area. If correct it seems more likely than not that our species destruction of the environment isn’t a recent development but rather has been a part of our nature from the start.

The Experimental Physics Community here in the United States has issued its Christmas Wish List of experiments to be funded over the next decade.

Every decade or so physicists here in the US submit their wish lists of the experiments they would like to see funded by the Federal Government through the Department of Energy via that department’s High Energy Physics Advisory Panel (HEPAP). Gone are the days when all Galileo had to do to advance science was to drop a couple of balls from the leaning tower of Pisa or all Ben Franklin had to do was go fly a kite. Today Big Science takes Big Money and much of that comes from the approximately one billion dollars that Washington spends on High Energy Physics (HEP).

One of the most famous experiments of all time, Galileo’s dropping two balls of different weights from the leaning tower of Pisa only required the two balls to perform. Those days are long gone as experimental physics gets more expensive every day. (Credit: SlidePlayer)

Taking input from hundreds of physicists a panel convened by the American Physical Society’s Division of Particle’s and Fields (DPF) drew up a wish list of experiments that, in their opinion, should be funded in order to provide the most science for the dollar. This panel, known as the Particle Physics Project Prioritization Panel (P5), was chaired by the distinguished physicist Hitoshi Murayama of the University of California at Berkeley. On December the eighth the panel released its report to both the Department of Energy and the public.

In the report the P5 panel called for the continued funding of projects now under construction or undergoing upgrades. These experiments include the Deep Underground Neutrino Experiment (DUNE), see my post of 30 July 2017, which it is hoped will finally give us an accurate measurement of the neutrino’s mass. Another neutrino experiment is the ICE CUBE neutrino telescope at the South Pole which just this year gave us our first image of what the Milky Way galaxy looks like, in neutrinos, see my post of 19 August 2023 Physicists hope that the planned expansion of ICE CUBE will reveal even more secrets of what the Universe looks like when you see it using neutrinos rather than light.

By analyzing how many and what type of neutrinos get detected physicists hope to get a better measurement of the rest mass of these ‘ghost particles’. (Credit: www.dunescience.org)

Finally the US should continue its contribution to the major upgrade of the Large Hadron Collider (LHC) at CERN in Switzerland. This upgrade is intended to increase the ‘luminosity’, that is the number of particles in the collider beam in order to obtain more events. This upgrade will increase the precision of the LHC’s measurements, hopefully pointing the way to new physics.

Of course the exciting part of the P5 report is the new experiments that are being proposed for funding. These include a small project entitled DarkSide-20K that is hoped to reveal some of the secrets of Dark Matter. Another such project is Belle II that will examine more closely the decay paths of the particles created in particle colliders.

But perhaps the most exciting long term project will be the initial design concept of a new American particle collider that will surpass the LHC in energy. You see one of the problems with the LHC that it uses protons in its collisions. Protons however are themselves made up of three smaller particles called quarks so when you smash two protons what actually happens is that a quark from each of the protons collide. Because of that you only get one third the available energy that gets turned into new particles. The other four quarks don’t get involved in the collision so two-thirds of the energy is kind of wasted.

One way of getting all the energy is to use a true elementary particle like the electron. Because of their small mass however an electron collider with the same energy as LHC would have to be thousands of kilometers in diameter, a project that would simply cost too much. One option that is being proposed is to use the electron’s heavier cousin the muon. Muons don’t survive very long however so there’s a lot of work to be done deciding exactly which way to go.

The electron is the easiest particle to work with, all of electronics is based upon it, but they are so light that they are not best suited for a particle accelerator. The Muon would be a better choice because it is 200 times as massive as an electron but they decay into electrons in about one millionth of a second. (Credit: YouTube)

Another exciting possibility is the use of a new technology in particle acceleration, the Wakefield accelerator in which charged particles are propelled by an ionized plasma like a surfboard by a wave. The advantage of the Wakefield accelerator is that it requires much less distance to achieve the same amount of acceleration. Ever since the first atom-smasher was built particle accelerators have gotten bigger and bigger, and more expensive with each increase in size. The construction and operation of the LHC costs as much as fighting a small war, which is why dozens of countries share the expense. It is hoped that the use of Wakefield accelerators could reverse this trend but as with any new technology there is still much to be learned about them in order to both make the maximum use of their advantages while overcoming their shortfalls. The P5 report requests about $10 million dollars to fund a preliminary design for the new particle accelerator that will address these issues.

It’s hoped that the new, Wakefield type of accelerator mechanism will reduce the size, and hence cost of particle accelerators but a great deal of research still needs to be carried out to really understand the technique. (Credit: American Physical Society)

Now, all of that is dependent upon the amount of funding that comes from the Federal Government through the Department of Energy. It is expected that Congress will give HEPAP a 3% increase over last year’s funding which would basically offset inflation. That’s assuming of course that Congress gets its act together and actually manages to pass a budget. With all the fighting going on in Washington it’s hard to see that coming to pass any time soon.

All spending for science, not just physics, accounts for only 2% of the federal budget. Is it any wonder that we’ve lost ground compared to countries like China that are investing in the future? (Credit: YouTube)

It used to be that the US led the world in Big Science. We always had the biggest particle accelerator, the biggest telescopes, and the biggest plasma reactor, none of that is true anymore, see my post of 28 June 2017. The technology we enjoy today came from that Big Science we conducted back in the 50’s, 60’s and 70’s. We simply need to invest more in the future if we expect to have any.
