  • Astronomers have found water vapour in the atmosphere of an exoplanet called 51 Pegasi b -- and achieved the feat using a brand new technique. Detected over 20 years ago, 51 Pegasi b was the first known "hot Jupiter" -- a Jupiter-like world orbiting close to its star. It isn't the first such planet to have water spotted in its atmosphere, but it is the first non-transiting one. All previous water detections relied on planets transiting -- slipping in front of -- their host star as seen from Earth. That's a slight problem, in that most exoplanets never make transits.
