A new exoplanet model screens rocky worlds by their ability to retain atmospheres over geologic timescales, helping narrow the search for potentially habitable planets beyond Earth.

NASA has confirmed thousands of exoplanets beyond our solar system - a number that continues to grow as new discoveries are ...

Astronomers have discovered two "super-puff" exoplanets orbiting the same star with densities lower than cotton candy.

A team of astronomers used the James Webb Space Telescope to create the first 3D atmospheric map of an exoplanet. The fiery WASP-18b, a massive “ultra-hot Jupiter,” revealed striking temperature ...

Planets beyond our solar system can have magnetic fields similar to those closer to home, astronomers said Tuesday after observing extreme winds on scorching worlds known as "hot Jupiters." ...

GJ 3378b has moved closer to the kind of world astronomers most want to find: small, rocky, temperate, and near enough for future telescopes to inspect in far greater detail. The planet circles a red ...

For the first time, astronomers have obtained convincing signs of the existence of magnetic fields in exoplanets. They came ...

Most exoplanet hunters chase biosignatures the way bird dogs chase the scent of a quail. But in a talk at the European Astrobiology Institute’s recent BEACON 25 conference in Reykjavik, astrophysicist ...
