WISE J104915.57-531906
Brown Dwarfs in our 'Backyard'

The third closest star system to the sun, called WISE J104915.57-531906, is at the center of the larger image, which was taken by NASA's Wide-field Infrared Survey Explorer (WISE). It appeared to be a single object, but a sharper image from Gemini Observatory in Chile (inset), revealed that it was binary star system, consisting of a pair of brown dwarfs. This is the closest star system to be discovered in nearly a century. The discovery was announced in March, 2013.
