NASA's Webb Reveals an Exoplanet Atmosphere as Never Seen Before
New observations show that a previously identified exoplanet, TOI-1075 b, is among the most massive super-Earths found so far.
Discovery Alert: Massive Planet is a 'Hulk' among Super-Earths
A new study of the "super-Earth" GJ 1252 b shows that the planet likely has a very minimal atmosphere or, possibly, no atmosphere at all.
Discovery Alert: Ultra-hot 'Super-Earth' Could Have No Atmosphere
A newly discovered 'super-Earth' lies in the habitable zone around its star, and appears to be in a prime position for further atmospheric investigation.
