"Is it possible to find trace evidence of supernovae from millions of years ago in the sediment lining the ocean floor? One astrophysicist has spent the better part of a decade trying to find the proverbial smoking gun to prove that it is. And now, it seems, he has succeeded.
Shawn Bishop, an astrophysicist at the Technical University in Munich, Germany, has been investigating the fossils of ancient bacteria on the ocean floor for several years now, in hopes of finding traces of an iron isotope produced in a supernova explosion some 2.2 million years ago. He presented promising preliminary findings at a physics conference in 2013. He has now confirmed those early findings, according to a new paper in the Proceedings of the National Academy of Sciences (PNAS). "The signal is definitely there," he told Gizmodo…"

That discovery was from a few years ago. Even earlier they looked at moon rock samples from '69 and '72 and found the same Fe60 isotopes. link |
