A planetary system 116 light-years from Earth has a peculiar pattern. It could flip the script on how planets form, ...

The fourth planet in the system is a rocky world, while the second and third ones are gas planets.

By Will Dunham WASHINGTON, Feb 14 (Reuters) - Astronomers have observed a planetary system that challenges current planet ...

Astronomers have found a distant world that challenges planetary formation theory, with a rocky planet where gas giants should be.

A global team of astronomers, led by the University of Warwick, have used a European Space Agency (ESA) telescope to discover ...

Astronomers have found a compact solar system whose planets line up in a way that, according to current models, should not be possible. Around the small star LHS 1903, a dense rocky world orbits on ...

A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

A closer look at the planets around a star called LHS 1903 may just flip our understanding of how planetary systems form.
