Ep. 12: Where Do Baby Stars Come From?

Most parents have had that uncomfortable conversation with their children at some point. Mommy, Daddy, where do stars come from?

You hear distances all the time in astronomy. This star is 10 light-years away; that galaxy is 50 million light-years away; that Big Bang over there happened 13.7 billion years ago. But how did astronomers actually figure out how far away everything is? It’s not a single measuring stick. Instead, astronomers have built up a […]

Ep. 4: The Search for Dark Matter

Dark matter . . . What is it? Nobody knows for sure, but it’s definitely there. Or maybe it’s not there, and we just need some redefinition of gravity at vast scales. Join Fraser and Pamela as we discuss the discovery, detection, and possible explanations of dark matter. Download Episode 4: In Search of Dark […]
