A planetary system 116 light-years from Earth has a peculiar pattern. It could flip the script on how planets form, scientists say.

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

Scientists have identified a rocky outer planet in a system where a gas giant was expected. The discovery challenges ...

A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

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

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

A NASA Hubble Space Telescope observation program called OPAL (Outer Planet Atmospheres Legacy) obtains long-term baseline observations of Jupiter, Saturn, Uranus, and Neptune in order to understand ...

Scientists used the European Space Agency's Cheops satellite to discover that the planetary system around the star LHS 1903 ...

Astronomers have found a distant world that challenges planetary formation theory, with a rocky planet where gas giants should be.
