Hubble Solves Merger Mystery From Milky Way’s Early Years

https://science.nasa.gov/missions/hubble/hubble-solves-merger-mystery-from-milky-ways-early-years/?utm_source=newsletter&utm_medium=email&utm_campaign=nn202633 Our home galaxy, the Milky Way, grew to its current size in part by consuming smaller galaxies. Now, new data from NASA’s Hubble Space Telescope shows definitive evidence of a dwarf galaxy merging with the young Milky Way galaxy in the earliest phases of its evolution. This finding extends our knowledge of our galaxy’s history 1.8 billion years further back in time than before.
