Hubble Hangouts were one hour chats about astronomy, generally related to the Hubble Space Telescope.
I have participated in several:
on Mocking the Universe, a workshop on the interface of models and survey design at STScI that I was the chair of the Science Organizing Committee for in July 2015;
on how Most Earth-like Planets Have Yet To Be Born, related to my paper with Peter Behroozi on History and Future of Cosmic Planet Formation;
on the Hubble Spectroscopic Legacy Archive.
