Scientists find that a glowing cloud that obscured a star was caused by a cataclysmic collision of two giant exoplanets.

A large, gaseous planet orbits a star that should have destroyed it.

With the discovery of six new exoplanets, scientists have tipped the scales and surpassed 5,500 exoplanets found (there are now 5,502 known exoplanets, to be exact).

Stars farther from the center of our galaxy possess fewer of the most common types of planets, a recent study shows.

Scientists used the Webb Telescope identified water vapor in the atmosphere of WASP-18 b, and made a temperature map of the planet as it slipped behind, and reappeared from, its star.

A team of astrophysicists and citizen scientists have identified what may be some of the last planets NASA’s retired Kepler space telescope observed during its nearly decade-long mission.

New data from NASA's Webb space telescope reveals new details about a strange but common planet type, a 'mini-Neptune.'

An international team of researchers has used NASA’s James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b.

The planet is rocky and almost precisely the same size as Earth, but whips around its star in only two days.

A second Earth-sized world is found in habitable zone of a star with three previously known planets.

A previously discovered "hot Jupiter" appears to be spiraling into its star, new data shows.

Two exoplanets orbiting a red dwarf star may be "water worlds." They are 218 light-years away in the constellation Lyra, and are unlike any planet found in our solar system.
