Hubble detects exoplanet with glowing water atmosphere

Friday, 4 August 2017

A global group of specialists, drove by the University of Exeter, made the new disclosure by watching sparkling water atoms in the air of the exoplanet WASP-121b with NASA's Hubble Space Telescope. 

So as to ponder the gas monster's stratosphere - a layer of climate where temperature increments with higher elevations - researchers utilized spectroscopy to examine how the planet's brilliance changed at various wavelengths of light. 

Water fume in the planet's climate, for instance, carries on in unsurprising routes in light of various wavelengths of light, contingent upon the temperature of the water. At cooler temperatures, water fume in the planet's upper climate squares light of explicit wavelengths emanating from more profound layers towards space. Be that as it may, at higher temperatures, the water atoms in the upper climate gleam at these wavelengths. 

The marvel is like what occurs with firecrackers, which get their hues from synthetic substances transmitting light. At the point when metallic substances are warmed and disintegrated, their electrons move into higher vitality states. Contingent upon the material, these electrons will discharge light at explicit wavelengths as they lose vitality: sodium produces orange-yellow and strontium produces red in this procedure, for instance. 

The water atoms in the air of WASP-121b comparatively emit radiation as they lose vitality, however it is as infrared light, which the human eye can't recognize.
