Show Notes
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.
