WISE J104915.57-531906 is at the center of the larger image, which was taken by the Wide-field Infrared Survey Explorer (WISE). This is the closest star system discovered since 1916, and the third closest to our sun. It is only 6.5 light-years away.
The original image appeared to be of a single object, but a sharper image from Gemini Observatory in Chile showed that it was from a pair of cool star-like bodies called brown dwarfs.
