New Horizons and event horizons
This episode we look at the Chinese lunar mission Chang’e 4, discuss the New Horizons flyby of Ultima Thule and wonder why a black hole isn’t as strong as a fridge magnet. We speak to Martin Harwit, author of Cosmic Discovery, about how some of the most important astronomical discoveries were first made. Hosted on Acast. See acast.com/privacy for more information.
