Wasp-39b and Its Parent Star (Artist's Impression)

Caption

A team of British and American astronomers used data from several telescopes on the ground and in space -- among them the NASA/ESA Hubble Space Telescope -- to study the atmosphere of the hot, bloated, Saturn-mass exoplanet WASP-39b, about 700 light-years from Earth. The analysis of the spectrum showed a large amount of water in the exoplanet's atmosphere -- three times more than in Saturn's atmosphere.
