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

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

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 ...

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 manner never seen ...

Astronomers have spotted an unusual 'inside-out' planetary system where a rocky world seems to have formed far beyond the realm typically reserved for gas giants.

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 ...

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

Astronomers say a newly discovered solar system about 116 light years from Earth is challenging long held ideas about how planets form.According to CNN, researchers using telescopes from NASA ...

In our Solar System, the inner planets (Mercury to Mars) are rocky, and the outer planets (Jupiter to Neptune) are gaseous. This planetary pattern – rock then gas - is consistently observed acro ...

A small red dwarf star in the Milky Way has drawn attention after astronomers mapped four closely orbiting planets around it. The system, known as LHS.

Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't ...
