Danger - explosive! This week’s episode is all about supernovae. These star-ripping, neutrino spewing explosions are important to various fields of astrophysics. Cormac, Cole, and Lucia discuss just when stars actually go supernova. And also, whether we can use gravitational waves to tell which compact object is left behind. Everybody gets to share their favourite supernova science and (as we all love to do) to complain about how much astronomers love old, inconsistent nomenclature. Enjoy!

In this episode, Cormac, Shashank and Cole dig deep into Galactic Archaeology as we look into the past of our Milky Way. Cole brings us a catastrophic computational collision, while Shashank gives us the low-down on low-metallicity, and we see just how the (Gaia) sausage gets made. We also discuss the rights, wrongs and funnies of Astronomers trying to name things, and the diverse design philosophies behind some of our favourite observational facilities.

In this episode, Shashank, Cole and Lucia bend time in their debut podcast together as we talk about the various ways astronomy is like time travel. Lucia gives us a peek into the past with the storied supernova Cas A, while Cole brings us on a nostalgic quest into gravitational wave memory. We hope you enjoy time traveling with us!
