Quebec scientists discover water world outside our solar system

A group of Quebec astrophysicists discovered that LHS 1140 B, which was first spotted 48 light-years away in 2017, is a water world.

LHS 1140 b “lives in its star's habitable zone, otherwise known as its ‘Goldilocks zone.’"
“This is the first time we have ever seen a hint of an atmosphere on a habitable zone rocky or ice-rich exoplanet," said Ryan MacDonald, a NASA Sagan Fellow
“the team might have even found evidence of ‘air’ on it.

James Webb Space Telescope suggests this exoplanet is our 'best bet' at finding an alien ocean

LHS 1140 b could make a great beach resort, with a possible ocean temperature of 68 degrees Fahrenheit.

Bewoonbare zone Exoplaneet LHS 1140b is waarschijnlijk Sneeuwbal- of Waterwereld

LHS 1140b is de op een na dichtstbijzijnde gematigde exoplaneet tot de Aarde, met een temperatuur die laag genoeg is om vloeibaar oppervlaktewater te ondersteunen.

La superterre LHS 1140 b pourrait être habitable avec une atmosphère contenant de l'azote, comme sur Terre !

On connaissait déjà des superterres avec une atmosphère mais, pour la première fois, on serait en présence d'une telle exoplanète qui serait en plus potentiellement habitable, à seulement 48 années-lumière du Système solaire. Cerise sur le gâteau, l'exoplanète LHS 1140 b exhibe dans le spectre de son atmosphère des indices de la présence d'azote, comme dans le cas de la Terre ou de Titan dans le Système solaire.
