In a groundbreaking discovery, scientists have identified a super-Earth exoplanet that may host vast oceans. This celestial body, believed to be rich in water, has sparked excitement in the scientific ...

Super-Earths can exist in wider orbits around their parent stars than was previously believed, suggesting these Earth-like exoplanets could be more common than we thought.

"It confirms K2-18 b to be our best chance to study a potential habitable environment beyond the solar system at the present time." ...

NASA says researchers studying exoplanets in space using the TESS space telescope have discovered a super-Earth orbiting its red star's habitable zone. Scientists say one "year" of its orbit would ...

The other is 70% larger than the Earth and might host a deep ocean. These two exoplanets are super-Earths — more massive than the Earth but smaller than ice giants like Uranus and Neptune.

Super-Earths have been spotted in other stars' habitable zones before. For example, a team using NASA's prolific Kepler Space Telescope announced the discovery of the potentially habitable world ...

Earth's magnetic field results from its flowing liquid metallic core. If super-Earths lack such dynamic cores, investigators suggested they might lack magnetic fields as well.

A super-Earth on a highly eccentric orbit would also be especially bad news for the inner planets, because it would be more likely to push or pull Earth, Mars and Venus into eccentric or tilted ...

Super-Earths — alien planets bigger than Earth, but containing less than 10 times its mass — may be undifferentiated hunks of rock, possessing neither a mantle nor a core, researchers found.

The two super-Earths, however, are a little too close for comfort, meaning they’re too hot to maintain liquid water. Both receive between 2.5 and eight times more energy from their star than ...

Researchers define a celestial body as a super-Earth in terms of its size: It has to be larger than Earth and smaller than Neptune. The term doesn't necessarily suggest that the exoplanet is ...
