In a conventional system like our own, rocky planets such as Mercury, Venus, Earth, and Mars orbit closest to the host star. Farther out, gas giants ...

Scientists have identified a rocky outer planet in a system where a gas giant was expected. The discovery challenges ...

Astronomers have discovered an exoplanetary system, 116 light-years away, that could redefine our understanding of how ...

An exoplanetary system located about 116 light-years from Earth may be reshaping scientists’ understanding of how planets ...

Astronomers have found a unique planetary system orbiting a red dwarf star. The system includes a rocky planet situated beyond its gaseous siblings, contradicting existing planet formation theories.

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 ...

Typically, from what astronomers have gathered thus far, star systems follow a tidy logic: small, rocky worlds huddle close to the warmth of their star, while massive gas giants bloat up in the colder ...

There is a typical configuration for planetary systems across the Milky Way. Astronomers have now stumbled across an outlier.

Published on The CHEOPS satellite enabled the discovery of a fourth exoplanet around the star LHS 1903, which would have formed after the others ...

Astronomers found a strange planetary system 116 light-years away. It orbits a red dwarf star called LHS 1903. The planets are arranged in an unexpected order. The outermost planet is rocky, which ...

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

Astronomers have discovered a distant solar system, LHS 1903, that defies traditional planet formation theories, prompting a reevaluation of these models.
