"17 Exoplanets: Potential Havens for Liquid Water and Life's Essential Ingredient"
NASA has identified 17 exoplanets that could potentially harbor oceans of liquid water beneath icy shells, even though they are too distant and cold to exist within their host star's habitable zone. These worlds, similar to Jupiter's moon Europa and Saturn's moon Enceladus, could be promising places to search for signs of life. The amount of geyser activity on two of these exoplanets, Proxima Centauri b and LHS1140 b, could exceed that of Europa by hundreds to thousands of times, making them prime targets for telescopic observations.
