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

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

Their observations of a faint, cool M-dwarf star called LHS 1903 revealed a system with a rocky world at its outer edge. LHS ...

Everything we know about the formation of solar systems might be wrong, says University of Florida astronomy professor Jian Ge and his postdoc, Bo Ma. They’ve discovered the first “binary-binary” – ...

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

Astronomers have observed a planetary system that challenges current planet formation theories, with a rocky planet that ...

HR 8799, located 129 light-years away, is home to a rare group of super-Jupiters, gas giants that are much larger than our own Jupiter. These planets, orbiting far from their star, present a unique ...

New work from Carnegie’s Alan Boss and Sandra Keiser provides surprising new details about the trigger that may have started the earliest phases of planet formation in our solar system. It is ...

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

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 ...

Gas giants are massive worlds made mostly of hydrogen and helium. They lack solid surfaces, and in our solar system, Jupiter ...
