Astrobites turns 100! For our ten squared-th episode we take a tour of all of the extremes of astrophysics: the heaviest and the lightest, the fastest and the slowest, the brightest and dimmest. In doing so, Shashank covers an astrobite on itty bitty particles that pack a big punch, Lucia talks about medium-ish galaxies and their black hole hearts, and Cormac panics about the danger of violent kilonovae. To help us celebrate, we meet up with some old friends to discuss dark matter, exoplanets, and how ridiculously long a Ph.D. takes.

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.
