An inside-out planetary system around the star LHS 1903 is turning everything that astronomers know about planet formation upside down.

The system, observed using the European Space Agency's Cheops space telescope, consists of four planets — two rocky and two ...

Scientists investigating the puzzling, long-lasting, and extreme dimming of a distant star have narrowed the suspects down to either a so-called “failed star” brown dwarf or a truly massive ...

Astronomers have long thought solar systems follow a simple pattern similar to our own: small, rocky worlds orbit close to ...

Scientists say a nearby red dwarf star hosts a planetary lineup that looks like a mirror image of our own solar system, with ...

The planetary system, located 120 light-years away, features four worlds orbiting a red dwarf star and challenges classical formation schemes.

The system consists of four planets, two rocky and two gaseous, orbiting a relatively small and dim star called a red dwarf.

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.

PARIS, France - Surprised astronomers said Thursday they have discovered a star with planets in a bizarre order that defies scientific expectations -- and suggests these faraway worlds formed in a ...

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...

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