Episode 370 - Explosions in space and citizen science

March 16, 2020

From galactic explosions, and waiting for supernova space is full of mysteries. What happens when a super massive black hole in a massive galaxy cluster...erupts? A massive explosion shred a hole 15 times larger than the Milky Way. What is happening with Betelgeuse? Could Betelgeuse just have shed it's coat? Is Betelgeuse about to go 'nova or is something else happening?   We find out about galactic research you can do from your couch. Tracing out a spiral is easy for humans to do, so why not help trace out a galaxy? Looking for something to do at home, why not citizen science helping trace galaxies?
