The birth of Milkomeda
Watch for the equivalent of 5 billion years as the merger of the Milky Way and the Andromeda Galaxy results in the birth of a single elliptical galaxy: Milkomeda.
Over the next 5 billion years, our home galaxy will merge with the Andromeda Galaxy. The galaxies will interact through several near-misses, drawing out long tidal "tails" of material that could cause our Sun to jump ship and join Andromeda before the final merger.
