The brown dwarf binary CFBDSIR 1458+10

This image of the brown dwarf binary CFBDSIR 1458+10 was obtained using the Laser Guide Star (LGS) Adaptive Optics system on the Keck II Telescope in Hawaii. Adaptive optics cancels out much of Earth’s atmospheric interference, improving the image sharpness by a factor of ten and enabling the very small separation binary to be resolved. This is the coolest pair of brown dwarfs found so far—the colder and dimmer of the two components is a candidate for the brown dwarf with the lowest temperature ever found. This colour picture was created from images taken through four different filters at near-infrared wavelengths.
