Brown dwarfs are smaller than the Sun but larger than Jupiter and are relatively dim in comparison to many other objects in the night sky. Their climate tends to be windy with many hot patches of clouds consisting of silicate dust and iron droplets. These giant clouds are able to change their size by becoming thicker or thinner and can move very quickly. But why is that?

New research carried out seeks to explain how clouds change shape and move quickly on brown dwarfs. Using insights from NASA’s Spitzer Space Telescope researchers have designed a model that shows giant waves causing extreme movement of particles in the brown dwarf’s atmosphere as well as the changing thickness of the silicate clouds. Researchers are also confident that the clouds are separated into different bands depending on their latitudes, and traveling at different speeds[…]
