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 ...

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

— -- 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 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 ...

Planet formation used to sound straightforward: dust clumps into rocks, rocks grow into worlds, and the rest is detail. A ...
