A team of astronomers has proposed that one of the most viable methods to identify liquid water and potential life forms on distant planets is to look for signs of reduced carbon in their atmospheres.
Notably, the presence of carbon dioxide in the atmospheres of rocky planets could be easily identified using NASA's James Webb Space Telescope (JWST).
"The Holy Grail in exoplanet science is to look for habitable worlds and the presence of life, but all the features that have been talked about so far have been beyond the reach of the newest observatories," said Julien de Wit, assistant professor of planetary sciences at MIT.
