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

An exoplanetary system located about 116 light-years from Earth may be reshaping scientists’ understanding of how planets form. It was discovered using data from NASA’s Transiting Exoplanet Survey ...

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

Typically, from what astronomers have gathered thus far, star systems follow a tidy logic: small, rocky worlds huddle close to the warmth of their star, while massive gas giants bloat up in the colder ...

An inside-out planetary system around the star LHS 1903 is turning everything that astronomers know about planet formation upside down.

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 ...

In a conventional system like our own, rocky planets such as Mercury, Venus, Earth, and Mars orbit closest to the host star. Farther out, gas giants ...

Published on The CHEOPS satellite enabled the discovery of a fourth exoplanet around the star LHS 1903, which would have formed after the others ...
