Wa­ter ice found in ex­oso­lar body

Down to Earth - - SCIENCE -

EV­I­DENCE OF wa­ter ice clouds out­side our so­lar sys­tem has been found for the first time. The clouds have been found on a brown dwarf named W0855. Brown dwarfs are ob­jects much big­ger than gi­ant plan­ets and much smaller than tiny stars. The clouds were de­tected by com­bin­ing images taken through a te­le­scope over three nights. Ice clouds are a great tool in un­der­stand­ing a planet's at­mos­phere. In our so­lar sys­tem, such clouds are present in plan­ets such as Jupiter and Saturn.
