Whacky Black Hole Collisions and Strange Uranian Rings

from Walkabout the Galaxy · host Josh Colwell, Jim Cooney, Tracy Becker

Mysterious bright blue flashes from relatively empty parts of the universe have a new possible explanation involving, what else, black holes. We explore this new idea to explain Luminous Fast Blue Optical Transients (LFBOTs) with black hole collisions, take a peek at the black hole in our own Milky Way, and discuss some puzzling observations of two of the rings of Uranus. Plus, we have a stupid stumper, exoplanet trivia, space news, and a top quark hot take!
