Another option, as University of Cambridge astronomer Nikku Madhusudhan recently proposed, is that the planet is a "hycean world." That term means hydrogen-over-ocean, since astronomers predict ...

The hypothetical worlds on which these biosignatures may be found are called hycean planets. Their name is a combination of "hydrogen" and ocean." It was first coined in 2021 by Nikku Madhusudhan ...

Madhusudhan and his two collaborators propose a new category of planet, which they dub a "Hycean" world. Much larger than Earth but smaller than Neptune, Hycean worlds would boast water oceans ...

The research shows that planet K2-18b is most likely a type called a Hycean planet, which is located within the habitable zone of its star and is covered in a liquid water ocean. This type of ...

The idea of a Hycean world is Dr Madhusudhan’s suggestion for an answer which would apply to planets like K2-18 b. It imagines a core of rock and iron about the size of Earth that is covered by ...

One other planet also has been identified orbiting this star. A 'HYCEAN WORLD' About 5,800 planets beyond our solar system, called exoplanets, have been discovered since the 1990s. Scientists have ...

K2-18b is considered a Hycean exoplanet — as opposed to a rocky planet — due to its potential to possess a hydrogen-rich atmosphere and surface covered in ocean water. Since it was discovered ...

He coined the concept of hycean planets, supposedly the best class of planets to look for life. The hycean planets have liquid oceans underneath a hydrogen rich atmosphere. The K2-18b is a hycean ...

The previous discovery was the first time carbon-based molecules were found in the atmosphere of an exoplanet in the habitable zone and added to studies suggesting it could be a Hycean planet ...
