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 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 ...

Gas giants possibly developed slowly in the solar system. They developed cores layer by layer within a disk of ice and dust ...

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

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 ...

Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't ...

A team of astronomers has identified a four-planet system orbiting the red dwarf star LHS 1903 that defies conventional expectations about how planets arrange themselves around their host stars. The ...

Jupiter’s swirling storms have concealed its true makeup for centuries, but a new model is finally peeling back the clouds. Researchers found the planet likely holds significantly more oxygen than the ...

Astronomers have found a compact solar system whose planets line up in a way that, according to current models, should not be ...

Astronomers have discovered an exoplanetary system, 116 light-years away, that could redefine our understanding of how planets form.

Gas giants are massive worlds made mostly of hydrogen and helium. They lack solid surfaces, and in our solar system, Jupiter ...

Astronomers have spent the past decade cataloguing thousands of planets beyond the solar system, many of them falling into a strange middle category. .
