TOI-270 d, located just 73 light years away, could be key to understanding a new class of planets. A study revealed it may be a giant rocky planet with a thick, hot atmosphere. NASA’s JWST detected ...

This illustration shows what the hot rocky exoplanet TRAPPIST-1 b could look like based on this work. TRAPPIST-1 b, the innermost of seven known planets in the TRAPPIST-1 system, orbits its star ...

"L 98-59 c could be the first planet smaller than 2 Earth radii with a definitively detected atmosphere," a team of ...

The faraway exoplanet could help provide answers as to why there are hardly any planets with twice the diameter of Earth. A super-Earth that could explain the universe's mysterious lack of certain ...

SEE ALSO: Scientists haven't found a rocky exoplanet with air. But now they have a plan. Further studies of exoplanet K2-18b, which orbits a cool dwarf star in its so-called "habitable zone ...

Preliminary data suggested that TRAPPIST-1b was a gray, barren rock ... offering a glimpse into the diversity of rocky ...

Previous data gathered by NASA's exoplanet hunter TESS (short for Transiting Exoplanet Survey Satellite) suggest the exoplanet's host star, L 98-59, is more active than previously thought and ...
