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

Analysis of an ancient meteorite suggests that rocky planets both near and distant from the sun may have formed at the same ...

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

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

We know that our Solar System is not the blueprint for all planetary systems out there. There are gas giant planets orbiting ...
