Did a Supernova Cause the Devonian Extinction? Brian Fields of the Unv. of Illinois - Astronomy News with The Cosmic Companion Sept. 1, 2020

This week, we are joined by Dr. Brian Fields of the University of Illinois. He recently headed a study showing how the Devonian extinction which took place on Earth 359 million years ago, may have been triggered by the supernova explosion of a nearby star.

We also look at a new experiment showing how life might survive a trip aboard an asteroid traveling from Mars to Earth, and we discuss new ideas showing how Earth may have been a water world since soon after its formation. Finally, we gaze out to the nearby galaxy, Andromeda, as the Hubble Space Telescope reveals a massive halo of ionized gas surrounding the massive collection of stars.
