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

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

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 ...

Look west just after sunset from this weekend for a chance to see some of six planets, though the best views will be had later this month.

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

New research suggests Einstein's general relativity explains the rarity of planets orbiting two suns. In tight binary systems ...

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