Episode 11 - Whirling planes, wandering black holes and alien supernovae

In this episode, Michelle and Payel discuss whether wandering intermediate black holes are mythical or not, how planes of satellites may form from cosmic accretion, how to form double hot Jupiters, whether Kelper's supernova remnant is an 'alien', whether Unions I is the faintest star cluster or the faintest galaxy, and just how old our globular clusters are.
