An animated view of the Local Group of galaxies: the Milky Way and Andromeda (M31), two great spirals falling toward each other across 2.5 million light-years at about 110 kilometres per second, with the smaller Triangulum (M33) nearby. The whole group streams through space at about 600 kilometres per second.

The Milky Way’s journey through the Local Group
Two great spirals — the Milky Way and Andromeda — fall toward each other across 2.5 million light-years at ~110 km/s, set to merge in ~4.5 billion years. The whole group streams through space at ~600 km/s.
