GJ 504 b has been one of astronomy’s stranger nearby worlds for years, a faint pink companion circling a sunlike star 57 ...

Astronomers have spent years searching for a possible hidden giant planet far beyond Neptune. Unusual orbits among distant ...

Astronomers have recently uncovered a remarkable planetary system around the faint orange star WASP-132, featuring two exoplanets that couldn’t be more different. One is a rocky world that completes ...

The hunt for Planet Nine continues as new discoveries make the Solar System’s biggest mystery even harder to solve. Is there ...

Nearly a decade after astronomers first proposed that a massive, unseen world is warping the paths of the most distant known ...

In 2020, astronomers detected WD 1856+534 b, a gas giant that orbits a star 81 light-years from Earth. This exoplanet, which is roughly six times the mass of Jupiter (making it a "super-Jupiter"), was ...

The orbits of the planets around the sun have been the source for many a scientific debate. Their current orbital properties are well understood but the planetary orbits have evolved and changed since ...

This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...

Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...

Astronomers from the Massachusetts Institute of Technology (MIT) have made an unusual discovery, finding a planet which is in the process of disintegrating. And as it decays, it is leaving behind a ...

Washington, D.C.—Observations of the highly unusual—sometimes called “forbidden”—exoplanet TOI-5205 b taken by JWST suggest the giant planet’s atmosphere has fewer heavier elements than its host star.
