Walkabout’s Guide to the Galaxy

The galactic council of astrophysicists has decided to annex a large structure of stars and make the formally part of our home, the Milky Way galaxy. Take that Andromeda galaxy! The gang discusses recent discoveries that show that various populations of stars on the outskirts of the Milky Way are actually part of a single structure that was perturbed by a long-ago collision between our galaxy and another one. The new findings make the diameter of the Milky Way 60% bigger, at 160,000 light years side to side. The bad news is that Josh can no longer use the Monty Python universe song to remember the size of the galaxy. Hear the latest astrophysical news together with completely random discussion about self-driving trucks on this episode of WtG!
