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

The planets around a nearby star seem to be in the wrong order, hinting that they formed through a different mechanism than the familiar one by which most systems grow ...

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 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 ...

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 ...

A global team of astronomers, led by the University of Warwick, have used a European Space Agency (ESA) telescope to discover a planetary system that turns our understanding of planet formation upside ...

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.

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

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

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

While idea may violate Occam’s razor, “it remains a speculative but logically open alternative,” says biologist Robert Endres ...

Researchers found that shifting gravity patterns may have encouraged the growth of Antarctica’s huge ice sheets ...
