A newly discovered nearby exoplanet has turned out to be an interesting one indeed: Not only is it a relatively rare kind of super-Earth, it may also be a water world, covered in a deep ocean! TOI ...

If super-Earths only had liquid water for relatively small slices of their existence–for instance, a million years or so–it would be “discouraging” for the hypothesis that these planets ...

Researchers using the Hubble Space Telescope have discovered water vapor in the atmosphere of planet K2-18b, located about ...

Observed orbiting a small reddish star just 137 light-years away from Earth, TOI-715 b just may support water. Astronomers hope to find out.

Astronomers have finally uncovered water vapor in the atmosphere of a super-Earth exoplanet orbiting within the habitable zone of its star. The find means that liquid water could also exist on the ...

If this "one-of-a-kind" exoplanet were confirmed to be a water world, its ocean would be significantly deeper than Earth's. While our planet is 70% water, oceans account for less than 1% of the ...

For years, scientists have speculated about the nature of water on exoplanets, especially on super-Earths and sub-Neptunes — planets larger than Earth but smaller than Neptune. The prevailing ...

Astronomers have discovered a new exoplanet orbiting a distant star that might constitute a “super-Earth” completely covered in water. The planet, dubbed TOI-1452 b, is about 70% larger than ...

Astronomers have determined that the atmosphere of super-Earth Gliese 1214 b is likely water-rich. However, this exoplanet is no Earth twin. The high temperature and density of the planet give it ...

A rocky and water-rich planet, ... This artist's conception shows the newly discovered super-Earth GJ 1214b, which orbits a red dwarf star 40 light-years from our Earth.

A Japanese research team has used the Subaru Telescope to determine that the super-Earth-sized planet Gliese 1214 b (GJ 1214 b) is likely to have a water-rich atmosphere.

Astronomers have determined that the atmosphere of super-Earth Gliese 1214 b is likely water-rich. However, this exoplanet is no Earth twin.
