The James Webb Space Telescope has taken the deepest look yet at Kepler-51d, an ultra-low-density exoplanet sometimes compared to cotton candy, and found that a thick atmospheric haze blocks nearly ...

A bizarre, ultra-light planet is cloaked in such a thick haze that even JWST can’t reveal its composition. Its unusual size and orbit are forcing scientists to rethink how planets form.

Scientists have discovered a distant solar system very much like our own, in which the orbits of all known planets lie in nearly the same plane and are aligned with the star's rotation. In recent ...

These three exoplanets are among the least dense ever found, and all attempts to probe their atmospheres have been blocked by ...

A hazy, ultra-light “super-puff” planet, Kepler-51d, is hiding its secrets and challenging how scientists understand planet formation.

AMES, Iowa – An international team of astronomers has used nearly three years of high precision data from NASA’s Kepler spacecraft to make the first observations of a planet outside our solar system ...

Kepler-51 is a young G-dwarf star hosting three super-puffs and one low-mass non-transiting exoplanet. Kepler-51d, the ...

CAPE CANAVERAL, Florida (Reuters) - NASA's planet-hunting Kepler space telescope has found 11 new planetary systems, including one with five planets all orbiting closer to their parent star than ...
