Walkabout the Galaxy

Mar 22, 2023

Compelling evidence for recent (1990’s!) volcanic activity on Venus has been un-Earthed, or rather un-Venused, by Robert Herrick through analysis of Magellan radar data. A volcanic vent seems to have roughly doubled in size in 1991. We discuss the difficulties of these observations and the implications for future missions. We also take a look at the role of supermassive black holes in controlling star formation in galaxies and have a numerical Top quark trivia. Warning: this episode gets off to a bit of a silly start, so jump ahead to the 24-minute mark if you want to get straight to Venus!
