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

The system, observed using the European Space Agency's Cheops space telescope, consists of four planets — two rocky and two ...

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...

An international team of astronomers has discovered a distant planetary system that challenges long-standing theories of how planets form.

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...
