Neogene Supernovae Showered Earth with Radioactive Debris

Neogene Supernovae Showered Earth with Radioactive Debris

Supernovae showered Earth with radioactive
debris. A series of massive supernova explosions near our
solar system showered the Earth with radioactive debris
between 3.2 and 1.7 million years ago, Australian National
University, April 6, 2016
