For the first time, water clouds have been detected [space.com] outside of the solar system. The body, a brown dwarf named WISE [nasa.gov] 0855, is only 7.2 light-years from Earth. It was studied from the Gemini North [gemini.edu] telescope in Hawaii for 13 nights.
The team found water vapor and also confirmed the object's temperature, which is about minus 10 degrees Fahrenheit (minus 23 degrees Celsius, or 250 kelvins). For comparison, the temperature at the top of Jupiter's clouds is about minus 225 degrees Fahrenheit (minus 143 degrees Celsius, or 130 kelvins).
