How can astronomers study something that nobody has ever seen? In this episode, we switch to the dark side to shine a light on one of the biggest questions in all of astrophysics: the nature of dark matter. Malena teaches us how dark matter helps galaxy clusters glow up, and Will takes a journey to the center of the Earth to find prehistoric prints from a big WIMP. Plus, Alex brings us our most romantic space sound yet.
