Hycean worlds are also called ocean worlds. They're planets covered in oceans that also have thick hydrogen atmospheres.

By Jackie Wattles, CNN (CNN) — Waters may be flowing on the surface of a colossal planet that lies about 120 light-years from Earth, according to new evidence uncovered by the James Webb Space ...

Planet in ‘habitable’ zone could have rare oceans and a possible sign ... there is the potential for life — but researchers still aren’t certain that these Hycean planets could sustain ...

Some planets in the so-called habitable zone, where temperatures are right for liquid water, are probably not good for life at all. Others outside that designated area might be perfectly comfortable.

Considering Hycean worlds expands the possible range of habitable planets because they can hang on to liquid water outside what is considered the traditional Goldilocks zone. "Hycean planets can ...

Some planetary scientists have dubbed these hypothetical planets Hycean worlds: ... In our Solar System, the habitable zone extends from just inside Earth’s orbit to just beyond Mars’ orbit.

There are no confirmed Hycean exoplanets just yet. And there is no planet quite like K2-18b in our own solar system, and that makes planets like it “poorly understood,” according to NASA.

Waters may be flowing on the surface of a colossal planet that lies about 120 light-years from Earth, according to new evidence uncovered by the James Webb Space Telescope.

“Our findings are a promising step towards a deeper understanding of Hycean worlds in this quest.”Researchers plan to continue using the Webb telescope to study the distant planet and attempt ...
