Glowing water atmosphere detected on an exoplanet
Scientists using NASA's Hubble Space Telescope claim to have discovered the strongest evidence yet for an exoplanet with an atmosphere of glowing water. The top of planet's atmosphere is heated to 2,500ÂºC, hot enough to boil some metals, scientists said. The planet named WASP-121b is 1.2 times massive than Jupiter and orbits its host star in 1.3 days, they added.
