The fourth planet in the system is a rocky world, while the second and third ones are gas planets.

Astronomers have discovered a planetary system that appears to flip one of astronomy's most reliable rules on its head.

Planet hunters have grown used to strange worlds, but a handful of discoveries now point to something even more radical: giant planets that loop around their stars on orbits so skewed they almost defy ...

Despite its unmemorable name, J2322-2650 is a strange system. A Jupiter-sized exoplanet orbits an energetic neutron star, which constantly bombards it with gamma rays. Now, a team of astronomers has ...

Scientists are unraveling the mysteries of "steam worlds"—exoplanets known as sub-Neptunes that are rich in water but orbit so close to their stars that their surfaces are shrouded in thick ...

Astronomers are investigating a strange class of exoplanets known as eccentric warm Jupiters — massive gas giants that orbit their stars in unexpected, elongated paths. Unlike their close-orbiting ...

This artist’s concept shows what the exoplanet called PSR J2322-2650b (left) may look like as it orbits a rapidly spinning neutron star called a pulsar (right). Gravitational forces from the much ...

"Our approach gives astronomers an idea of how many spots a star might have, where they are located, and how bright or dark they are." When you purchase through links on our site, we may earn an ...
