LONG LOST LO­CAL GAL­AXY

Sky at Night Magazine - - BULLETIN -

The Milky Way has a long-lost sib­ling. Re­cent sim­u­la­tions show that dwarf gal­axy M32 is the core of a gal­axy that was once as large as our own but had its outer stars stripped away by An­dromeda. “Astronomer­s have been study­ing the Lo­cal Group – the Milky Way, An­dromeda and their com­pan­ions – for so long. It was shock­ing to re­alise that the Milky Way had a large sib­ling, and we never knew about it,” says Eric Bell from the Uni­ver­sity of Michi­gan who co-led the study.
