Astronomers believe the young Milky Way once swallowed a dwarf galaxy
Astronomers believe they've mapped an important sequence of events that shaped our galaxy 10 billion years ago. In a paper published in Nature Astronomy today, researchers from the Instituto de Astrofisica de Canarias (IAC) share their findings that a dwarf galaxy, Gaia-Enceladus, once collided and merged with the early Milky Way. Their discovery offers a new understanding of how the Milky Way formed.
