There are worlds like hot Jupiters, gigantic and very hot, as well as ocean worlds and super-Earths with a rocky structure ...

For centuries, astronomers faced the challenge of classifying objects in space based on their appearance. When observing an ...

Talk about a hot mess. Scientists have uncovered a hellish “lava world” where temperatures soar to a blistering 2,700 degrees Fahrenheit — hot enough to melt rock into a churning ocean of magma and ...

A young planet 370 light-years away is emitting an unexpected radio signal, giving a clearer view of how giant planets grow.

Scientists using NASA’s James Webb Space Telescope have found a unique planet in another star system that’s shaped like a lemon. The lopsided Jupiter-style planet is so bizarre that it may blur the ...

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.

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

Astronomers have identified a giant planet circling a tiny red dwarf star at a distance so extreme that it sits about 690 times farther from its star than Earth is from the Sun. The discovery pushes ...

Astronomers have discovered a new class of exoplanet that defies traditional categories of planetary classification. In a groundbreaking study published in Nature Astronomy, researchers led by the ...

A team of researchers has uncovered nearly 70 rogue planets in our galaxy, the largest group ever discovered, according to the European Southern Observatory. Rogue planets are described as "elusive ...

Astronomers have discovered two gas giant planets orbiting stars in the Beehive cluster, a collection of about 1,000 tightly packed stars. The planets are the first ever found around sun-like stars in ...
