Hubble detects Exoplanet with glowing water atmosphere

Scientists have found the strongest evidence to date for a stratosphere on an enormous planet outside our solar system.


An international team of researchers, led by the University of Exeter, made the new discovery by observing glowing water molecules in the atmosphere of the exoplanet WASP-121b with NASA’s Hubble Space Telescope.

In order to study the gas giant’s stratosphere - a layer of atmosphere where temperature increases with higher altitudes - scientists used spectroscopy to analyse how the planet’s brightness changed at different wavelengths of light.
