LONG LOST LOCAL GALAXY
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.
