| Did NASA find a planet with water? Water vapor has been discovered on a planet roughly the size of Neptune; the smallest exoplanet known to have water. HAT-P-11b is 120 light years away in the constellation Cygnus and sits close to its star in a five-day orbit. |
NASA’s James Webb Space Telescope in its study of K2-18 b, an exoplanet, discovered the presence of carbon dioxide and methane.
This suggests that K2-18b could be a Hycean exoplanet, one which has the potential to possess a hydrogen-rich atmosphere and a water ocean-covered surface.
