A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

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

Far beyond our solar system, in the distant Pegasus constellation, lies a star system that is reshaping our understanding of planetary formation. HR 8799, located 129 light-years away, is home to a ...

LHS 1903 flips rock and gas on their heads, hinting that late-born planets can rewrite the rules around common red dwarfs for now.
