@nationalspacesociety's TikTok video "This simulation shows the future of the three largest galaxies in our Local Group: the Milky Way, Andromeda, and Triangulum. In about 4 billion years, the Milky Way and Andromeda are expected to collide. Roughly 2 billion years later, they'll merge into a single giant elliptical galaxy, while Triangulum continues its journey nearby.
