Learn more about the Kepler-51 star system and some of the ''oddball" planets that reside there.

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

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 ...

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 ...

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

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 ...

It provides a dynamic, time-resolved view of planetary transformation, a missing link between young inflated worlds and the compact sub-Neptunes that populate the galaxy.
