"NASA Discovers 17 Exoplanets with Potential Life-Sustaining Oceans"

NASA has identified 17 exoplanets that could potentially have subsurface oceans buried beneath thick sheets of ice, making them promising candidates for hosting life. These planets, similar to Jupiter's icy moons, receive enough internal heating from the decay of radioactive elements and tidal forces from their host stars to maintain internal oceans. While their host stars may not provide conditions warm enough for liquid water on the surface, these planets may generate enough heat below the surface to sustain a subsurface ocean. Follow-up observations will involve capturing the emission spectra of light traveling through these planets' atmospheres to search for chemical signs of life.
