Noting the weather patterns of a brown dwarf


Hubble space telescopes and NASA's Spitzer investigated the stormy atmosphere of a brown dwarf called 2MASSJ22282889-431 026, creating the "climate map" far closer to this kind of cold orbs similar to stars. The forecast shows clouds planet-sized wind-driven involving these strange worlds.
