(future galaxy resulting from merger of Milky Way and Andromeda)
Milkomeda (aka Milkdromeda) is a nickname given
to a future galaxy resulting from the
future Andromeda-Milky Way collision,
the galaxy merger of the Milky Way and
Andromeda (M31). This is expected to occur in about 4.5
gigayears, given their trajectories and masses.
More recent analysis and simulations claim that the collision and
merger may not occur, with about 50% probability.
