ESO News | First 3D observations of an exoplanet’s atmosphere

Astronomers have revealed for the first time the 3D structure of an exoplanet’s atmosphere. Tylos (or WASP-121b) is a gaseous, giant exoplanet located some 900 light-years away. Astronomers were able to differentiate three different layers in its atmosphere, where winds carry elements like hydrogen, sodium, iron at extreme speeds, creating weather patterns never seen before. This was possible by combining all four telescope units of ESO’s Very Large Telescope in Chile.
