Image: James Webb observations of the nearby rocky exoplanet Gliese 486 b suggest it has no thick atmosphere
This is the most precise measurement yet of terrestrial exoplanet's thermal emission with JWST. Gliese 486 is a red dwarf only 26 light years from the Sun. The exoplanet Gliese 486 b orbits the star once every 36 hours. It is bigger, denser and hotter than Earth....
