Nearby supernova ashes continue to rain on Earth
Washington DC (SPX) Apr 22, 2016
Traces of 60Fe detected in space indicate that a nearby supernova occurred within the last few million years. The iron isotope 60Fe, which is very rare, is created when a massive star collapses in the form of supernova. Walter Binns et al. detected 60Fe in cosmic rays flying through space, revealing that the contents of a nearby supernova are being sprinkled on Earth to this day. Some previous reports have found samples of the isotope that have accumulated on Earth and the Moon in the distan ... read more
