We may never know if there’s an afterlife, but we do know that death isn’t the end for some unusual objects in space. Alex tells us about a zombie star that may have gone supernova twice, Will covers white dwarfs with a (potentially) explosive afterlife, and Malena talks about planets that might survive a supernova.

The Transiting Exoplanet Survey Satellite was designed to find exoplanets -- but, it turns out that there's a huge amount of other science that it can do, too! In this episode, we provide an inside look at the TESS Ninja 3 conference and explore the range of science being studied with TESS: comets, stellar clusters and flares, trans-Neptunian objects, black holes, and more.

The laws of physics that govern our universe rely on only a handful of constants. But are these values really constant after all? In this episode, we explore new research into the gravitational constant, the diffuse gas fraction in the universe, and a very peculiar planet's orbital period.

Goblins, giants, and dwarfs, oh my! Today we discuss the variety of mythical creatures in astronomy, including ghost and goblin galaxies, sneezy M dwarfs with cyclops planets, and oscillating giant stars.

"Reduce, reuse, recycle." You may practice this advice in your own life, but did you know the universe does the same thing on a much larger scale? Will tells us about quasars that reduce, Malena talks about galactic recycling, and Alex describes galaxies that reuse hydrogen.
