Water clouds on exoplanet 7 light years away

Not that it is likely to be raining on this exoplanet too much but it is the first time such an observation has been made about its cloud composition. The exoplanet in question is literally a cool brown dwarf with a temperature of around 0°C making it a bit warmer than Jupiter, so may be a chance for snow?

Found intially using images from NASA’s WISE infrared space telescope by Kevin Luhman, an astronomer at Pennsylvania State University.

Exoplanet designated as WISE J0855-0714.

The evidence of water was attributed to work led by Jacqueline Faherty using the ground based 6.5-metre Magellan Baade telescope telescope in Chile.
