Share Supernovae like the Crab nebula forged the heavy elements found on Earth. But neutron star mergers also play a role. NASA; ESA; NRAO/AUI/NSF; G. Dubner/University of Buenos Aires Trace seabed plutonium points to stellar forges of heavy elements May. 13, 2021 , 2:00 PM With the discovery of just a few hundred radioactive atoms in seabed deposits, researchers have confirmed that blast debris from a pair of stellar explosions swept across Earth within the past 10 million years—whil...

Traces of rare forms of iron and plutonium have been found at the bottom of the Pacific Ocean, after some kind of cataclysm in outer space created this

Scientists believe some heavy elements are forged when a massive star goes through its death throes and explodes as a supernova. Here, the supernova Cassiopeia A was captured in a false-color image from NASA. Traces of rare forms of iron and plutonium have been found at the bottom of the Pacific Ocean, after some kind of cataclysm in outer space created this radioactive stuff and sent it raining down on our planet. The extraterrestrial debris arrived on Earth within the last 10 million years, a...

Our Planet Is Travelling Through The Debris of Ancient Supernovae 21 APRIL 2021 Radioactive dust deep beneath the ocean waves suggests that Earth is moving through a massive cloud left behind by an exploded star. Continuously, for the last 33,000 years, space has been seeding Earth with a rare isotope of iron forged in supernovae.   Its not the first time that the isotope, known as iron-60, has dusted our planet. But it does contribute to a growing body of evidence that such dusting is ongoi...
