Researchers then scoured the globe for thin layers of radioactive isotopes in rock strata and in 1999 struck figurative gold: Samples from beneath the ocean revealed some hard metallic layers, known as ferromanganese crusts that form slowly over millions of years, containing iron-60, an isotope with a half-life of 2.6 million years -- so short that the material must be much younger than Earth. The iron-60 was in a stratum laid down 2.2 million years ago. Similar layers of iron-60 have since been found elsewhere in the oceans. Astronomers have also been scouring the skies for groups of stars that could have created the blasts, with suspicion falling on two: the Scorpius-Centaurus (Sco-Cen) association, a group of more than 400 stars that would have been about 400 light-years away when the supernova occurred; and the Tucana-Horologium (Tuc-Hor) moving group which was 200 light-years away at the time.
However, the few iron-60 samples provide little information about the location of the offending supernova. In fact, in a paper posted on the arXiv.org preprint server yesterday, Ellis and colleagues argue that... Current samples "very tentatively favor" the Tuc-Hor group, Ellis says.
Today, however, Anton Wallner, a nuclear physicist at the Australian National University (ANU) in Canberra and colleagues report a new, much more detailed examination of iron-60 deposition around the globe and argue that Earth was exposed to a burst of multiple supernovae. Analyzing 120 ocean-floor samples from the Atlantic, Pacific, and Indian oceans, the team reports that iron-60 is detectable everywhere and that it doesn't seem to represent a single event, as the effected strata stretch from 1.7 million to 3.2 million years ago, as the researchers report today in Nature. "It suggests there were a series of supernovae, one after another," ...

I can’t help thinking that you are a very like minded person.
I hope we have more conversations in the future.
Here is another must read:
I've some familiarity with Clube and Napier's work of circa 1980, which was very similar to the much earlier work of Immanuel Velikovsky, even fiddled somewhat with the ancient chronology (Dr. V considered the historical timeline reconstruction to be his main work, C&N probably regard their cometary encounter scenario as their main work).
The photo of the debris on Mars is a photo that must be of a rather recent strike, since it is on the surface.
This must be happening all over the cosmos. Thank God our solar system has the big vacuum cleaner Jupiter, or humanity would probably not have made it this far.
I'd like to hear more from these guys who did this article.
I think it wrong to dismiss Velikovsky as unscientific. Religious traditions are replete with stories of catastrophe. It’s just a matter of putting it all together.
A recent publication, well done, by a British author.
Yes, of course it is -- but often the common thread running through fringe authors like Hancock is to dismiss V as unscientific. I'd be surprised to learn that Hancock hasn't, considering how long he's been around and the number of books he's penned.

Well yeah, he’s known as a scientific “bomb thrower.”
Still, he did a good job with his new book. The catastrophe crowd loved it, because they have been, like Noah, swimming against the politically motivated current for too long.
BTW, the supernova explanation IMHO supercedes the EPH from the late TVF. (FReepers everywhere murmur, 'gee thanks, 'Civ)
