As reported by Ukrinform, this is stated in the press release NASA.

James Webb’s discovery thus complements recent research suggesting that K2-18 b could potentially be a Hyckean exoplanet that could have a hydrogen-rich atmosphere and an ocean-covered surface.

Hykean planets are a hypothetical type of habitable planets.

It is stated that K2-18 b orbits the cool dwarf star K2-18 and is located 120 light-years away from Earth in the constellation Leo.

Exoplanets like K2-18 b, which lies between Earth and Neptune in size, are unlike anything else in our solar system.

The lack of nearby equivalent planets means that these “sub-Neptunes” are poorly understood, and the nature of their atmospheres is a subject of active debate among astronomers.

“Our research highlights the importance of looking at a variety of habitable environments in the search for life elsewhere. “Traditionally, the search for life on exoplanets has focused mainly on smaller rocky planets, but the larger Hykean worlds are much more amenable to atmospheric observations,” said astronomer Nikku Madhusudhan of the University of Cambridge. .

As reported by Ukrinform, a group of astronomers using the TESS space telescope discovered that: two sub-Neptune-class exoplanets.
