Water detected in atmosphere of Jupiter-like exoplanet
Astronomers have detected the presence of water molecules in the atmosphere of a nearby exoplanet. Located 50 light years away, '51 Pegasi b' is the first exoplanet discovered orbiting a star and the first known 'hot Jupiter'. It has a high surface temperature, as it orbits its parent star very closely, at a distance of only 75 lakh km.
