Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new ...

The origin of super-Earths and sub-Neptunes has been revealed in a system of four young planets that are dramatically losing ...

Discover the fascinating journey of a planet that orbits a black hole. This video delves into the dynamics of celestial ...

Exoplanets like Earth have been discovered but not all Earth-like planets are equal when it comes to alien life.

In theory, a planet may be able to orbit a binary star system in a figure of eight, but it may not be particularly stable, ...

A Tatooine-like world with a key difference from the desert planet in "Star Wars" has been serendipitously discovered orbiting not two stars, but a pair of brown dwarfs. What's more, this wacky planet ...

— -- Goldilocks, like most fairy tales, offers children a lesson and a happy ending. Whether a Goldilocks planet offers astronomers something similar still hangs up in the air, with the story's ...

This artist’s concept shows what the exoplanet PSR J2322-2650b may look like. Gravitational forces from the much heavier pulsar it orbits are pulling the Jupiter-mass world into this bizarre lemon ...

A team of international researchers led by Tomas Stolker in the Netherlands has imaged a young gas giant exoplanet near a 12-million-year-old star. The planet is orbiting a star whose planet formation ...

Astronomers have long searched for life within a rather narrow ring around a star, the "habitable zone," where a planet should be neither too hot nor too cold for liquid water. A new study argues that ...

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 ...

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 ...
