A planet relatively close to Earth could be the first ever detected with a potentially life-sustaining liquid ocean outside our Solar System, according to scientists using the James Webb space ...

Temperate exoplanet LHS 1140 b may be a world completely covered in ice (left) similar to Jupiter’s moon Europa or be an ice world with a liquid substellar ocean and a cloudy atmosphere (centre). LHS ...

As much as 95% of an exoplanet's water could be trapped forever deep inside its iron core, transforming what we thought we knew about water worlds and potentially rendering them even more habitable ...

A University of Michigan astronomer used NASA's James Webb Space Telescope (JWST) to discover an exoplanet with a promising temperature, an indication of possible liquid water present. The discovery ...

Data suggests K2-18b is a "world with an ocean that is teeming with life," said study lead author Nikku Madhusudhan, an astrophysicist at the University of Cambridge in England. A whopping 8.6 times ...

An exoplanet in the habitable zone of its own sun is now suspected to have a liquid ocean and an atmosphere, meaning it has potential to harbor life similar to that on Earth. The planet, named LHS ...

A Southwest Research Institute-led study modeled the chemistry of TOI-270 d, an exoplanet between Earth and Neptune in size, finding evidence that it could be a giant rocky planet shrouded in a thick, ...

Discovered in 2011 by NASA's Kepler Space Telescope, TrEs-2b absorbs 99% of the light it is struck with and reflects only 1%, ...

An ancient rocky world so close to its star that its surface is largely molten should have been stripped bare of gas long ago. Instead, new observations reveal that this ultra-hot planet has somehow ...
