    The Milky Way had a previously unknown big sibling that was torn apart by the neighboring Andromeda galaxy long ago, a new study suggests. Andromeda and the Milky Way are the two largest members of the Local Group, a collection of more than 50 galaxies packed into a dumbbell-shaped region of space about 10 million light-years across. Andromeda was not kind to the onetime third-biggest member of this family, devouring it about 2 billion years ago, according to the new research. "Astronomers have been studying the Local Group — the Milky Way, Andromeda and their companions — for so long,"...

This entertaining composite image compares the angular size of the nearby galaxy to a brighter, more familiar celestial sight. In it, a deep exposure of Andromeda, tracing beautiful blue star clusters in spiral arms far beyond the bright yellow core, is combined...
