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

Scientists say a nearby red dwarf star hosts a planetary lineup that looks like a mirror image of our own solar system, with ...

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 ...

Astronomers have spotted an unusual 'inside-out' planetary system where a rocky world seems to have formed far beyond the realm typically reserved for gas giants.

Surprised astronomers said Thursday they have discovered a star with planets in a bizarre order that defies scientific ...

With this new survey, astronomers have gained a peek inside a stage of exoplanet system formation they have yet to fully ...

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