In four billion years, the Milky Way and Andromeda galaxies will collide, according to a study in the Astrophysical Journal. Roeland van der Marel, an astronomer at the Space Telescope Science Institute, talks about how this discovery was made, and the fate of our solar system.
In the SciFri Snack: Stargazers, be on the lookout. Astronomer Roeland van der Marel says that when the Milky Way collides with the Andromeda Galaxy, you’re in for one heck of a view -- and you only have 4 billion years to prepare. Check out more SciFri Snacks -- and join a conversation about what you've heard -- at Sound Cloud.
