Description

Dr. Ilana MacDonald is an Astrophysicist who did her PhD at the University of Toronto. Her thesis topic was on the gravitational waves that come from binary black holes, that is, the ripples in space-time that come off of two black holes spiralling around each other. She now works in the Astronomy Department at UofT doing primarily course management, but also a lot of public outreach and education. Prior to the pandemic, Dr. Ilana designed and gave shows in their portable planetarium, and since then she has given several online talks on a variety of topics primarily through "Cosmos From Your Couch" and "Astro at Home". Her favourite things to talk about in astronomy is black holes and gravitational waves, space travel, the possibilities of extraterrestrial life, the expanding universe, how stars die, and much more. If you are an oxygen breather, you are going to LOVE this episode.
