What’s the opposite of high-energy astrophysics? In today’s episode, we recognize the unsung heroes of astronomy: the low-energy, sleepy objects that keep on chugging in spite of it all. Will describes recent findings that the Sun is a bit sleepier than its peers, Alex Illustr(is/ates) how galaxy cluster fly-bys can make an ultra-diffuse galaxy a little more chill, and Malena delivers an uncharacteristically non-thematic space sound. To top it off, we learn about the slowest song ever written (hold your applause until the end).
