The dim glow of the binary brown dwarf system CFBDSIR 1458+10, as seen in the H-band (1.6 microns) by the Keck II Telescope’s powerful Laser Guide Star Adaptive Optics system. Field of view is 1.5 by 1.5 arcseconds wide. CFBDSIR 1458+10B is the smaller, cooler partner of the pair. Credit: Michael Liu (IfA/Hawaii), W.M. Keck Observatory
