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

A rocky exoplanet in the LHS 1903 system defies planet formation models, hinting that gravitational upheaval reshaped the red dwarf’s four worlds.

Deep in the older, denser reaches of the Milky Way, there is a red dwarf star that shouldn’t exist — or at least, its family of planets shouldn’t look the way it does. The star is LHS 1903, and it ...

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

Astronomers have found a rocky planet where it should not exist, orbiting far from a cool red star. Could this strange ...

A team of international astronomers has announced the discovery of an 'inside-out' planetary system that defies the established understanding of planetary patterns.

For millions of years, a frozen wanderer drifted between the stars before slipping into our solar system as 3I/ATLAS—only the ...

The planets around a nearby star seem to be in the wrong order, hinting that they formed through a different mechanism than the familiar one by which most systems grow ...
