UCLA astrophysicists have now measured the shape of the orbits of exoplanets—from the size of Jupiter down to the size of ...

Scientists have used data from NASA's retired planet-hunting space telescope 'Kepler' to discover that small and large worlds have very different upbringings. The team found that larger planets on non ...

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 ...

An international team of astronomers has discovered a distant planetary system that challenges long-standing theories of how planets form. Across our galaxy, astronomers routinely observe a ...

New research using NASA’s James Webb Space Telescope examines the maximum sizes of gas giant exoplanets, measuring chemical compositions and formation processes in the HR 8799 system.
