Paleontology News for November 2017.

I came across a couple of interesting stories detailing new discoveries in the field of paleontology. The stories concern my two favourite kinds of extinct animals, dinosaurs and trilobites so I have to talk about them.

I’ll start with the article about trilobites. For those who aren’t familiar with these creatures from the beginning of multi-cellular life trilobites are arthropods, similar to crustaceans, spider and insects but much simpler in physiology. (See picture below showing trilobite anatomy) Trilobites lived from the beginning of the Cambrian period (about 550 million years ago) until the mass extinction at the end of the Permian period (about 250 million years ago). During that long stretch of time over 20,000 different species are known to have existed so trilobites are a fairly common fossil; I have quite a few in my collection.

But usually trilobite fossils consist only of the hard outer shell of the animal, the internal anatomy has decayed completely away. Only rare specimens show any of the ‘soft parts’ of animals as old as trilobites. And since trilobites are one of the earliest forms of complex life their internal workings could tell us a lot about how the nervous system, or circulatory systems or other internal parts evolved.

Now a group of researchers headed by Melanie Hopkins of the American Museum of Natural History have published a paper describing the earliest known digestive system of a trilobite. The specimens used in the study come from the Guanshan biota in the Yunnan province of China, a location that produces fossils of exceptional preservation. The fossils used in the study come from two different species, Palaeolenus lantenoisi and Redlichia mansuyi, that are common at the site.

Multiple specimens were literally dissected, imagine dissecting an animal dead for 550 million years, in order find their stomach and trace their alimentary canal. In trilobites the stomach, also know as the crop, is situated very close to the mouth beneath the glabella, see picture above. The researchers also discovered pairs of digestive organs on each side of the alimentary canal, which runs nearly the entire length of the trilobite. The image below shows some of the dissected specimens along with drawings of what was found.

The digestive system of trilobites may seem simple compared to that of modern arthropods but for their time these were highly evolved. This study has given us some of the details about how the internal workings of a very important group of animals developed.

The second story I’d like to discuss comes from France where the longest known trackway of sauropod dinosaur footprints have been excavated in the Jura Mountains near the village of Plagne. The Jura Mountains by the way is where we get the name of the Jurassic Period.

The sauropod dinosaurs are the familiar long necked, long tailed plant eaters who were the largest animals to ever walk on the Earth. The 155 meter long trackway contains 110 steps and the impressions range from a little over a meter to three meters in diameter. The image below shows the trackway.

According to the ‘Societe des Naturalistes d’Oyonnax’, a local group of amateur paleontologists who discovered the footprints, the trackway was made by a single animal approximately 35 meters in length with a mass of around 35,000 kilos. The animal walked with an average stride of 2.8 meters at a speed of about 4 kilometers per hour. The image below shows an artist’s representation of the sauropod dinosaur walking along the trackway while humans are beneath it.

With each new find by paleontologists we are learning more about the history of life on Earth. It is a history far longer and more extensive than the history of the single species we think is so important.





Hey Nibiru, Three strikes and You’re OUT!!!

In this blog I have tried to avoid even mentioning pseudo-science. Whether it be UFOs or Bigfoot or ESP there’s just no arguing with ‘True Believers’. No matter how many times they fail miserably to provide any hard evidence the ‘True Believers’ still refuse to even admit to the possibility that they could be wrong. In fact they will often get angry with you for saying ‘show me’.

Today however I’m going to make an exception and talk a little bit about Nibiru, or planet X because in just the last two months there have been THREE (!) different precise dates on which Nibiru was supposed to have destroyed us all, but we’re still here. Three complete, total failures in just two months. The image below shows an artists idea of Nibiru, which is supposed to be four times as massive as Earth, causing cataclysms here on our planet.

You’d think that level of failure would be sufficient to make all ‘True Believers’ completely ashamed of themselves. However I’m certain that a new ‘corrected’ date of destruction will soon be announced and accepted by the faithful. After all, the only other choice they have is to accept the fact that they’ve been a fool.

Actually the idea of Nibiru causing the apocalypse has been around for quite a while now. It was back in 1995 that Nancy Lieder claimed that she was receiving signals through an implant in her brain from aliens in the Zeta Reticuli star system. According to the Zetas a planet from the outer reaches of our solar system was going to sweep past the Earth causing all kinds of destruction by it’s gravitational and magnetic fields, this event was scheduled to take place in May of 2003. (The Zetas are Grey Aliens by the way, how many different kinds of aliens are visiting Earth I don’t know.)

The visiting planet gained the name Nibiru when Ms. Lieder read a book by a researcher on ancient alien visitations named Zecharia Sitchin. According to Mr. Sitchin, Nibiru is the name given by the Babylonians to a planet that sweeps past the Earth every 3,600 years and the inhabitants of Nibiru became the gods of Mesopotamia, chariots of the gods you remember! (By the way accredited scholars of Mesopotamia have no regard for Mr. Sitchin’s interpretation of the Babylonian records.) The image below shows Mr. Sitchin with a Babylonian tablet he claims mentions Nibiru.

Sounds like Mr. Sitchin and Ms. Lieder are coming to the same conclusion from different paths doesn’t it? Well no, Lieder and Sitchin soon disagreed about when the planet would return, Lieder was already on record as saying 2003 while Sitchin said somewhere between 2090 and 2370!

Anyway I trust that you are all aware the Nibiru did not pass by Earth in 2003 but that didn’t stop the ‘True Believers’. They just picked a new date and Nibiru soon became the engine of destruction for the Mayan Apocalypse of December 21, 2012, which also didn’t happen.

But just because a planet doesn’t exist won’t stop people from making it a part of their attempts to gain attention, fame and money. Earlier this year a ‘Christian numerologist’ named David Meade tied together passages from the bible with Nibiru along with the American total solar eclipse back on August 21st to again predict Earthly destruction beginning on September the 23rd. When Nibiru failed to show up on time the date was immediately pushed back to mid October and then the 19th of November. Well it’s now 22November and no Nibiru! Let’s just hope the doomsday ‘theorists’ will at least wait a while before threatening us again with a non-existent planet.

I hope you’ve noticed that I haven’t mentioned any of the evidence against the existence of Nibiru. All I’ve said so far is that Nibiru never shows up when it’s predicted to destroy us. Still it’s easy to demonstrate that Nibiru is nothing more than a fantasy. First of all, if a planet four times the size of Earth came closer than the orbit of Saturn it would be quickly discovered by not only professional astronomers but by the thousands of amateur astronomers out there who are hoping to discover a comet or an asteroid. Anything as big as a planet wouldn’t be able to hide for a week!

Also, as astronomer Mike Brown has pointed out, any planet that moved back and forth between the outer and inner planets would sooner or later, within a few million years, have an encounter with Jupiter and be thrown out of the solar system. Finally, our solar system is a well-mannered, orderly place, so much so that it has often been compared to a clock; it wouldn’t be so orderly if there was anything Nibiru wandering around. The image below illustrates Nibiru’s orbit showing how Planet X goes right past the largest planets in the solar system.

Now I know that the people out there who are trying to sell books despite the fact that they don’t know anything will soon come up with some new fantasy. Still, hopefully by now Nibiru and its ‘supporters’ have been revealed as the delusions they always were.

Space News for November 2017

There have been several very interesting things happening in space this past month so we’ve got a lot to discuss. I almost don’t know where to start.

I’ll start with the discovery of the second closest exo-planet, that is a planet orbiting another star. The star is called Ross 128 and sits in the constellation of Virgo at a distance of 11.2 Light Years (or 3.4 Parsecs) while the planet has been designated as Ross 128b.

Not only is Ross 128b close to earth it’s also just 35% more massive than our Earth so it’s expected to be a rocky planet. In addition Ross 128b orbits its star at a distance within what astronomers call the habitable zone. The habitable zone is defined as the region of space where the light coming from a star is just strong enough to give a planet a surface temperature suitable for liquid water to exist. And liquid water is obviously a prerequisite for life similar to that here on Earth.

How far the habitable zone is from a star depends on how much energy the star emits every second. A large hot star like Sirius would have its habitable zone out where Jupiter or Saturn are in our Solar System but Ross 128 is a small dim star; its habitable zone is much closer than even the orbit of Mercury. In fact Ross 128b is so close it orbits Ross 128 every 9.9 days!

One more thing about Ross 128b that has astronomers excited is that its parent star is a calm mild star, not prone to flare-ups that could make life impossible on their planets. Based on what we know about Ross 128b the planet looks like the best bet right now for discovering life outside our Solar System.

And we may be doing just that quite soon. You see over the next few years a new generation of telescopes, collectively know as Extremely Large Telescopes (ELTs) will begin to study the Universe. These huge instruments, along with the James Webb space telescope to be launched next year, should be able to separate Ross128b from the glare of its parent star and possibly detect signs of life on its surface. Detecting the spectral lines of Oxygen in the planets atmosphere in particular would be very strong evidence of life. Sometime in the next ten years we may know for certain! The image below shows an artist’s idea of what the Planet Ross 128b may look like along with artwork from NASA of the James Webb space telescope.

The second story is related to the first because it concerns another close, potentially inhabited exo-planet orbiting around Luyten’s star at a distance of only 12 light years. The planet GJ273b is about three times the mass of Earth and also orbits within the habitable zone of Luyten’s star.

A new organization called METI, Messaging Extra Terrestrial Intelligence, has begun sending radio signals, including music, to any potential civilization on GJ273b using a radio telescope in Norway starting in October and will be repeated in April of 2018. Traveling at the speed of light the signals will arrive at GJ273b in November of 2030. If there is a technical civilization on GJ273b then we may hear an answer in 2043. The image below shows the EISCAT parabolic dish antenna used to transmit the signals to GJ273b.

Finally I like to talk a little more about one of those new telescopes that could revolutionize our knowledge of the universe. The Zwicky Transient Facility (ZTF) may not be the largest astronomical instrument but its digital camera, with a resolution of 24,000 by 24,000 pixels, will be capable of scanning the entire northern sky each night for transient events, anything that changes in brightness.

ZTF will quickly spot and localize objects ranging from supernovas to Near Earth Asteroids to supermassive black holes devouring entire stars in other galaxies. ZTF is also expected to detect the visible components of gravity wave events. Whenever ZTF spots something of interest other, more powerful but narrower focused instruments will be brought to bear to study the event in greater detail.

The ZTF telescope took its first photograph on November 14, see image below, and will be fully operational next year. If you’d like to read more about the ZTF click on the link below to be taken to the University of Maryland’s ZTF website.

These are just a few more reasons to think that we could be in for some very exciting discoveries over the next few decades!




Movie Review: Thor: Ragnarok

The Fenris wolf fights The Incredible Hulk!!! In my opinion that alone was worth the price of admission. The new movie Thor: Ragnarok from Marvel Studios is a nice mixture of ancient and modern mythologies.

Back when I was in grade school I much preferred the Marvel Comics to DC, Superman was especially lame and Batman was a joke. Then in high school I got interested in Norse mythology so I guess I was predisposed to like the new Thor movie. The image below is a poster for the movie Thor: Ragnarok.

For those who aren’t familiar with the ‘Fate of the Gods’ or ‘Twilight of the Gods’, we’re not quite sure which Ragnarok means, let me give you a little background. In Norse mythology Ragnarok is the final battle between the forces of good and evil. Most mythologies predict some such conflict in the future but unlike the Christian myth of Armageddon where the good guys just win and Satan in cast into the bottomless pit the battle of Ragnarok is a lot bloodier for both sides.

Three winters without a summer herald the attack on Asgard, the home of the Gods by the Giants (Jötnar) of Jötunheimr. The giants are led by Surtr the fire Giant. The Fenris wolf breaks free of his bonds and devours the Sun while Jörmungandr, the Midgard serpent rises from the depths of the ocean causing violent storms. Even Loki breaks free of his chains to join the war on the Gods.

The Aesir assemble for battle led by one-eyed Odin (Germanic Woden which is where we get Wednesday), his sons Ty’r (Tuesday) and Thor (Thursday) along with a fertility God named Freye (Friday) and the ever faithful guardian of the bifrost bridge Heimdallr. Below is a woodcut by the artist Otto Spamer of Odin in his full splendor.

Odin by Otto Spamer

In the battle the wolf swallows Odin alive but is killed by Ty’r, Freye and Surtr kill each other. Thor slays Jörmungandr but takes only nine steps before dropping dead from the monster’s poison. In the final act only Heimdallr and Loki remain to face each other, faithful against faithless and die by each others sword. A later Christian addition has a new world being reborn out of the ashes as Odin’s dead son Baldr the beautiful rises from the realm of the Goddess of the Dead Hel (Who gives us the word Hell) and rules a world without evil.

So much for the ancient myths, Marvel studios has now given us a new take on the myth in their current movie Thor: Ragnarok. Unlike the original myth Thor: Ragnarok is a part of the ‘Marvel Universe’ so the good guys have to win without too many losses. Obviously they aren’t going to let Thor die because he has to appear in the next Avengers movie. Nevertheless there is plenty of mayhem on both sides.

Most of the original cast is here. Hel, now called Hela and played by Cate Blanchett, is the chief evildoer but she’s joined by Fenris and Surtr. The images below show Hela the Goddess of Death and the Fenris wolf.

Thor (Chris Hemsworth) is joined by Odin (Anthony Hopkins) and Heimdallr (Idris Elba). In the movie Loki has his mischievous moments but in the end becomes a good guy probably because Tom Hiddleston has done such a splendid job with the character that Marvel doesn’t want to lose him, or make him into a real bad guy. (Hint to Marvel studios: What about a Loki movie. Of course he’d have to be an anti-hero but how about a Marvel remake of something like a fistful of dollars?)

An addition to the story from elsewhere in the Marvel Universe is The Incredible Hulk (Mark Ruffalo) who gets to fight the Fenris wolf as I mentioned earlier. A five minute long cameo is also provided by Doctor Strange played by Benedict Cumberbatch that has absolutely nothing to do with the plot of the movie but which introduces Thor to Doctor Strange.

Now I’m not going to give away any of the major plot points, O’k I did mention that the Hulk fights the Fenris wolf, but I will make a few criticisms. I do think that Hela (Hel) could have been more effective if she’d actually had fewer lines. As death personified she should have been something more like a walking plague, killing by simply a thought or glance. Also the section on Jeff Goldbloom’s landfill planet either needed to be explained better, or reduced, and less Jeff Goldbloom is always a good thing to me.

Another thing before I forget, Hela uses Odin’s eternal flame to animate a lot of dead warriors to be her Zombie army but then Thor and the Hulk just knock’em all over like bowling pins. I’ve seen this before, the good guys have to fight their way through a big mass of nobodies before they face the real bad guys. It’s really just padding the film and it’s boring. Try using a little more imagination.

Nevertheless I certainly enjoyed Thor: Ragnarok although you may have noticed that the serpent Jörmungandr didn’t appear. Since he the one who kills Thor in the ancient myth I guess Marvel is saving him until Chris Hemsworth is tired of the role and they start planning on a reboot. Below are a few images of artwork that have been inspired by the myth of Ragnarok.

Have Scientists taken a critical step in understanding the Chemistry of how life began and an update on our Interstellar Visitor.

Ever since Charles Darwin’s ‘On the Origin of Species’ had demonstrated that all of the multiform types of living creatures here on Earth had evolved over millions of years from a single primitive type of life scientists have sought to understand how that first living thing came into being. Much has been learned in the last 150 years but many of the details of the chemistry involved in the development of a complex, self-replicating molecular system, i.e. a simple living cell, are still unknown.

Now researchers at The Scripps Research Institute (TSRI) have published a paper in which they claim to have found a chemical compound that played a key role in assembling short nucleotide chains (early genetic material) with peptide chains (short version of proteins) encapsulated in a lipid vesicles (early cell walls). Finding a catalyst that could combine these three distinct types of chemicals, and which could have existed on the primitive Earth has been a goal of ‘Origins of Life’ researchers for the past several decades.

The scientists at Scripps have given their compound the name diamidophosphate or DAP for short and have published their results in the journal ‘Nature Chemistry’. The figure below shows the chemical diagram and the structure of DAP.

According to lead researcher Doctor Ramanarayanan Krishnamurthy DAP “would have allowed other chemistries that were not possible before, potentially leading to the first simple, cell based living entities.” “With DAP and water and these mild conditions, you can get these three important classes of pre-biological molecules to come together and be transformed, creating the opportunity for them to interact together, ” Krishnamurthy said. The image below shows DAP and the three classes of chemicals needed to build a simple cell.

Whether or not DAP was THE chemical catalyst that enabled the formation of the first living cell will be difficult to prove four billion years after the fact but Dr. Krishnamurthy and his co-authors intend to continue their study of DAP and other phosphorylating compounds.

Before I go I’d like to take a moment to update one of my posts of just last week (4Nov17) about the interstellar visitor that entered our solar system and is now on its way back into the void between the stars. Well A/2017 U1 has been given the new name of 1I Oumuamua. The 1I indicates that it is the first interstellar object ever discovered while Oumuamua is a Hawaiian word meaning scout or Messenger. 1I Oumuamua was discovered by the Pan-STARRS telescope in Hawaii after all. The image below shows Oumuamua’s path through our solar system.

More importantly a group of Astronomers are preparing a paper in which they give their estimate as to the place of origin of Oumuamua along with how long it took to reach our solar system. Working backward along the trajectory of Oumuamua Eric Gaidos and Jonathan P. Williams of the University of Hawaii along with Adam Kraus of the University of Texas are of the opinion that Oumuamua originated in the Carina and Columba Associations, clusters of young stars at a distance of 215 to 365 light years. (Carina and Columba are constellations in the southern sky).

Current research estimates that the Carina and Columba Associations were an active star-forming region about 45 million years ago. If Oumuamua had been thrown out of a newly forming solar system in the direction of our Sun at a velocity of 1-2 kilometers per second it could just now be arriving in our solar system!

Even though Oumuamua was only near enough for us to study it for about a month we have already learned a great deal from it. This is only the start, in the years to come I have no doubt that we’ll be learning a great deal more.



Star Talk on National Geographic Channel: Neil deGrasse Tyson interviews the Former Head of DARPA, Arati Prabhaker.

Last Sunday night, 5November17, the National Geographic channel broadcast the latest episode of their series ‘Star Talk’, the ‘Intersection of Science and Popular Culture’ with host Neil deGrasse Tyson. As always the show centered around a taped interview by Dr. Tyson with a guest of some importance in some field of science. Last night’s guest was Doctor Arati Prabhaker who recently stepped down from her position as the Head of the Defense Advanced Research Programs Agency or DARPA. The picture below shows Dr. Tyson with Dr. Prabhaker.

The interview began with Dr. Tyson asking Dr. Prabhaker to describe what DARPA is and relate a bit about its history. DARPA was formed in 1958, in the wake of the USSR’s launching the first artificial satellite Sputnik I, as an agency within the Department of Defense assigned with finding ways to adapt the latest technology to our nation’s military readiness.

Over the years DARPA has had a few amazing successes such as ‘Stealth’ radar invisible aircraft and precision guided ‘Smart Bombs’ but not all of DARPA’s work has involved weapons. In fact some of the agency’s breakthroughs have been turned into many of the hi-tech devices we use everyday. One DARPA program called ‘ARPA net’ developed many of the protocols that computers use to talk to each other, a critical part of the Internet. Also, I was personally a witness to DARPA’s funding of the development of Gallium Arsenide (GaAs) as a semiconductor material for high frequency circuits; you wouldn’t have a cell phone without it.

In fact some of the technology currently being supported by DARPA has already been discussed on this blog in previous posts. The DARPA challenge race for driverless cars was the main topic of my post of 17Jun17. Meanwhile DARPA’s funding has also helped to advance the engineering of prosthetic limbs for wounded soldiers, some of the results of which were discussed in my post of 23Sept17. The images below show some of the results of DARPA’s support in these fields. The first is from the driverless vehicle challenge while the second shows the latest result of prosthetic engineering and which is currently undergoing clinical trials by the Food and Drug Administration.

While Dr. Tyson’s interview with Dr. Prabhaker was taped earlier several guests joined Neil in his studio at the Hayden planetarium. One was his usual sidekick the comic Chuck Nice who seemed unnaturally nervous while trying to make jokes about military weapons systems. The second guest was the journalist Sharon Weinberger who has reported about DARPA for 17 years and has written a book ‘The Imagineers of War’ about DARPA. The cover of ‘The Imagineers of War’ is show below.

The episode’s final guest, Hod Lipson is a Mechanical Engineer who took part in DARPA’s road challenge with a team from Cornell University and who has written about the coming revolution in driverless cars appropriately titled ‘Driverless’. Both books are available at Amazon. The cover of ‘Driverless is shown below.

Driverless by Hod Lipson (Credit:

At the end of every episode Dr. Tyson makes a few concluding comments. A few of the things he said last night bear repeating. First Neil suggested that there should be a DARPA type of agency ‘in every branch of human culture’. But the comment that I think we would all do well to consider was ‘at DARPA they take risks, risks that other sources of money do not take. Well the day you stop making mistakes is the day you can be sure you are not on the frontier.”


An Interstellar Visitor enters our Solar System. What is A/2017 U1 and what can we learn about what it is and where did it come from.

Over the past twenty years or so NASA has been working on a effort to find and catalog all of the small objects in our Solar System that could one day pose a threat to us here on Earth. A critical part of this effort was the design and construction of telescopes especially suited to surveying large parts of the sky in very fine detail.

One of these telescopes is Pan-STARRS at the observatory atop Mona Kea in Hawaii. With a mirror of 1.8 meters in diameter the telescope is smaller than most professional instruments, but with a 1.4 Gigapixel camera Pan-STARRS can photograph the entire sky several times a month.

That’s what you need in order to find Near Earth Objects (NEOs). Take two pictures of the same part of the sky a couple of weeks apart and compare them. Anything that moves between the two images is an NEO.

Just a few weeks ago on October 19th, Doctor Rob Weryk of the University of Hawaii’s Institute for Astronomy found something special with the Pan-STARRS telescope. At first Dr. Weryk thought he’d just found another

space rock, there are literally thousands out there. Dr. Weryk gave the 500-meter rock the designation A/2017 U1.

When he calculated the object’s position and velocity however Doctor Weryk realized that whatever it was it was moving too fast to remain in orbit around the sun. The object was a visitor from interstellar space making its first and only trip around our Sun. The photograph below shows the small dot that is A/2019 U1.

Astronomers had long been expecting a visit from such an object. Many models of how solar systems form have a certain amount of matter being expelled as the star and planets condense. These outcasts would then wander between the stars where they could occasionally be drawn into the gravitational field of another star.

The orbits followed by these temporary visitors are not closed elliptical paths like those of planets or very comets but are an open-ended curve known as a hyperbola. Whereas the planets repeat the same orbit over and over again, an object on a hyperbolic trajectory is on a one time only orbit around a star. The figure below shows the difference between an elliptic and hyperbolic orbit.

A/2017 U1 made its closest approach to our Sun back on September 9th, more than a month before it was discovered. Coming within 23 million miles of our star A/2017 U1’s velocity increased to almost 90 kilometers per second. It passed within 15 million miles of Earth on October 14th at a velocity of 60 kps; three times the velocity that the New Horizons space probe had on its way to Pluto. In ten years or so, when it has left our Solar System behind A/2017 U1 will still have a velocity of about 25kps, faster than that of the Voyager I space probe, the first man made object to leave our Solar System. The image below shows the path of A/2017 U1 as it swung around the Sun.

So, what was A/2017 U1? What was it made of? Where did it come from?

To be honest we didn’t learn a great deal about A/2017 U1. It was very small, didn’t come that close and is already too far away for even the most powerful telescopes to see anymore. Really all we know for certain is that A/2017 U1 came from the direction of the constellation of Lyra and that it looked more like an asteroid than a comet.

But we know it came from the beyond, from outside out little neighborhood of the Galaxy. And that means there will be others, and each time one visits we will learn a little more about them. That’s the way science works after all.

Solar Eclipse of 1207BC helps to date Pharaohs? Interesting but I’m not so sure about the connection.

Back in August I was lucky enough to have had an almost perfect view of the recent total Solar eclipse that crossed the USA, (See Post of 24August17) so went I came across an article entitled “Solar Eclipse of 1207BC helps to date the Pharaohs” I was instantly intrigued. It only took me a few minutes to find and download the original article at the journal ‘Astronomy and Geophysics’. What I read was certainly interesting but also clearly displayed some of the difficulties in trying to use modern science to study ancient, semi-legendary records of past events.

The article was written by Colin J. Humphreys of Selwyn College at Canbridge University and Graeme Waddington, an independent scholar. What Humphreys and Waddington propose is that the astronomical miracle described the Old Testament book of Joshua (Joshua 10:12-14) was not as usually translated the Sun and Moon standing still at Joshua’s command but rather a description of a Solar eclipse.

This idea is not actually new. As Humphreys and Waddington themselves point out the linguist Robert Wilson realized over a hundred years ago that the Hebrew words dôm and ‘amad could also mean that the Sun and Moon stopped shining, i.e. an eclipse. However, when astronomers did the calculations to find that ancient eclipse they discovered that there was none appearing in Canaan around the right time.

What Humphreys and Waddington realized was that the earlier calculations of ancient Solar Eclipses ignored the possibility of the event being an annular solar eclipse. Now an annular eclipse occurs when the Moon is at the farthest point in its orbit and therefore appears smaller in our sky, too small in fact to completely cover the Sun leaving a bright annular ring of sunlight. See picture below.

Doing the calculations Doctors Humphreys and Waddington found that there had been an annular eclipse across North Africa and Canaan on the 30th of October in the year 1207 BC. This eclipse they claim is the miraculous event depicted in Joshua, chapter 10. The image below shows the path of the annular eclipse.

Now to the ancient Hebrews an annular eclipse of the Sun would still be more than spooky enough to be remembered and connected to their legendary hero Joshua. At this point however the authors indulge in some hand waving, just suppose type arguments to provide a little more evidence. For example they claim that the reduction in sunlight during the afternoon, followed by the return of light after the eclipse’s maximum and then concluding with a real sunset could very easily be described as “The Sun did not hurry to set for about a whole day” (Joshua 10:13 New Revised Standard Version or NRSV).

To me this is part of the problem of trying to use modern science to describe biblical or mythological stories IN DETAIL! These stories have been so elaborated, so dramatized that any historical reality is deeply buried. You have to massage the surviving evidence to make it appropriate for the scientific explanation you’re suggesting.

In fact the very existence of the biblical hero Joshua and the Israelite “conquest” of Canaan has been seriously called into question. Professor Israel Finkelstein of the Department of Archeology at Tel Aviv University has published a series of papers and books detailing a broad spectrum of evidence that the Hebrew people developed in situ, that is the Hebrews were originally Canaanites who developed a different culture and came to consider themselves a different people, not an outside people who conquered the central highlands region of Canaan. According to Doctor Finkelstein, the stories of Exodus and Joshua are simply that, stories. There is no archeological evidence to support them. Trying to connect an astronomical event to such “history” may be completely impossible.

(If you’re interested in leaning about Doctor Finkelstein’s work I heartily recommend his “The Quest for Historical Israel” available at Amazon)

Still, up to this point I was with Doctors Humphreys and Waddington, but then they made a connection that just went to far for me. At the time of their eclipse, 30Oct1207BC, the Pharaoh in Egypt was named Merneptah, the son and successor of the famous Rameses the second. Now it happens that we know the number of years these men reigned better than the actual dates. The first year of Mernephat’s reign is considered to have been anywhere between 1213BC to 1204BC.

However, Merneptah is also know for having inscribed a stone slab with details of his victories (such a stone slab is known as a stele), including his victory over Israel! The images below show the entire stele along with the section mentioning Israel.

Based on this stele Humphreys and Waddington have concluded that Merneptah’s first year as Pharaoh was either 1210BC or 1209BC. As I first read their conclusion I didn’t see the connection to Joshua’s eclipse, Mernephat’s stele mentions Israel but says nothing about anything like an eclipse. Then I thought, are they assuming that Mernephat’s victory over Israel was also Joshua’s victory over the Amorites!!!

That’s way too much of an assumption for me! There is no evidence of any kind that Mernephat and Joshua fought each other or indeed existed at the same time, if Joshua existed at all. Assuming that the two stories of battles are about the same battle is just pure speculation.

I have decided to attempt to contact Doctors Humphreys and Waddington to ask for a little clarification, who knows maybe I missed something somewhere. I’ll let you know when and if I receive an answer.

UPDATE: I received a reply from Sir Colin Humphreys, one of the authors of the article. (I didn’t know he was a Sir! The Queen’s birthday honours list of 2010 according to Wikipedia.)

Anyway, Sir Colin accepts that the battles fought by Joshua and Merneptah were not the same but he does believe that the two campaigns were near enough in time to allow him to use Joshua’s Miracle (The Eclipse of 1207BCE) to more accurately date Merneptah’s reign as Pharaoh.

I can only say once again that I am reluctant to accept the bible that literally. Or Merneptah for that matter, remember his stele states that “Israel is laid waste, his seed is not”. Well that’s a boast that rings pretty hollow. And Merneptah’s stele is contemporary with his campaign while the book of Joshua is considered to have been written 500 years later!
