Feature Guest: Brian Thomas
We have this impression of our planet as isolated from the rest of the universe, our lives cut off from the drama unfolding elsewhere in our galaxy. But what if the course of life’s evolution on Earth was intimately connected to events well beyond our solar system. It now seems likely that supernovae hundreds of light-years away have profoundly affected our history and may even account for climatic changes just as our species was emerging. Today we’re joined here at The Star Spot by astrophysicist Brian Thomas to explore this fascinating discovery.
