Astronomers have discovered a planetary system that appears to flip one of astronomy's most reliable rules on its head.

Explore the story of our solar system’s formation, tracing how a vast cloud of gas and dust collapsed under gravity, collisions, and angular momentum to create a thin, spinning protolanetary disc.

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 found a strange planetary system 116 light-years away. It orbits a red dwarf star called LHS 1903. The planets are arranged in an unexpected order. The outermost planet is rocky, which ...

A small red dwarf star in the Milky Way has drawn attention after astronomers mapped four closely orbiting planets around it. The system, known as LHS.

Astronomers have found a rocky planet where it should not exist, orbiting far from a cool red star. Could this strange ...

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

Of the solar system’s planets, Saturn piques the human imagination with its signature rings and impressive moon count of 274. But compelling new research reignites theories of an ancient collision ...
