Snowball Earth was Cold and Scary and the Milky Way Magnetic Field is a Mess

from Walkabout the Galaxy · host Josh Colwell, Addie Dove, Jim Cooney, Audrey Martin

The Earth spent some crazy amounts of time (tens of millions of years) completely frozen over. And not, in the grand scheme of things, all that long ago. New research shows the ocean was salty and super-cold. How did life survive? New techniques using radio observations reveal a complicated and twisty galactic magnetic field. Join us for an icy, winter olympics themed episode to find out all this and more.
