"NASA Discovers 17 Exoplanets with Potential Liquid Oceans"
TL;DR
NASA has identified 17 exoplanets that could potentially have subsurface oceans buried beneath thick sheets of ice. These planets, similar to Jupiter's icy moons, may be promising places to search for signs of life. While their host stars may not provide enough heat to keep water in liquid form on the surface, internal sources of heat such as radioactive decay and tidal forces could sustain a subsurface ocean. Telescopes may be able to detect geological activity on these planets, and the emission spectra of their atmospheres could provide clues about the presence of life.
