For the first time, evidence of water ice clouds has been found outside our own solar system. A team of astronomers at the Carnegie Institution led by Jacqueline Faherty took 151 photographs of the brown dwarf designated WISE J085510.83-071442.5 over three nights, and when that data was compared to predicted models of the atmospheres of brown dwarfs it was discovered that the atmosphere of WISE J085510.83-071442.5 has clouds of frozen water and sulfide.
A recent video released by the Carnegie Institution visualizes and summarizes the discovery and shows the significance of water ice clouds in the atmospheres of planets and brown dwarfs.
