The Milky Way now has a twin (or two)




Research presented today at the International Astronomical Union General Assembly in Beijing has found the first group of galaxies that is just like ours, a rare sight in the local Universe.

The Milky Way is a fairly typical galaxy on its own, but when paired with its close neighbours - the Magellanic Clouds - it is very rare, and could have been one of a kind, until a survey of our local Universe found another two examples just like us.
