Artist impression of the planetary system with four planets,around a small red star,called LHS1903. Caption: Astronomers have long thought solar systems follow a simple pattern similar to our own: ...

Astronomers have discovered a distant solar system, LHS 1903, that defies traditional planet formation theories, prompting a reevaluation of these models.

The discovery overturns traditional models that predicted gas giants in outer orbits and suggests planets can form in gas-poor environments.

Scientists say a nearby red dwarf star hosts a planetary lineup that looks like a mirror image of our own solar system, with rocky worlds bookending a pair of gas-rich planets. Around the star LHS ...

During a break from looking at planets around other stars, ESA’s CHaracterising ExOPlanet Satellite (Cheops) mission has observed a dwarf planet in our own Solar System and made a decisive ...
