Episode: Perseverance, Cache Me While You Can!
Description: Three missions, including two rovers, are arriving at Mars this month. We preview some of the unique aspects of the Mars Perseverance rover, and we explore the curious case of a giant galaxy with, apparently, no central black hole. Hear how merging black holes might use gravitational waves to shoot across the cosmos, plus a poetic sponsor, and the word Scutum is said way too many times.
