Synopsis
In another wide-ranging episode, we discuss how atmospheric and oceanic chemistry changes wiped out most life on Earth 250 million years ago, the best evidence yet for a third type of supernova, and the importance of timekeeping for astronomy and space missions. We also have historical clock trivia and a lot of space news to share.
