\n“Hycean worlds are planets with habitable ocean-covered surfaces and H2-rich atmospheres. Their lower densities, larger sizes, and lighter atmospheres compared to Earth-like planets make hycean worlds more readily detectable and more conducive for atmospheric characterization. Similarly, their wider habitable zone compared to Earth-like planets also makes them more abundant, with over a dozen hycean candidates already identified.”
