Astronomers want to collect as much data as possible using as many systems as possible. Sometimes that requires coordination ...

Only 11.4 light-years away, two exoplanets have been detected around a neighboring star. One of them, Gl725Bc, is located in ...

A distant star system with four super-sized gas giants has revealed a surprise. Thanks to JWST’s powerful vision, astronomers detected sulfur in their atmospheres — a chemical clue that they formed ...

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

What if humanity could no longer live on Earth? Perhaps a catastrophic event forced us to find a new home among the stars.

A newly identified planet candidate, HD 137010 b, looks strikingly Earth-like in size and orbit — but it may be colder than Mars due to its dimmer star. If it has a thick enough atmosphere, though, ...

A newly discovered planet orbiting a distant star may change scientists’ understanding of how planetary systems form. View on ...

Worlds like Tatooine—the iconic twin-sun planet from Star Wars—are no longer confined to science fiction; they have entered ...

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 ...

If a gas giant planet is big enough to ignite deuterium fusion, it becomes a brown dwarf instead of a planet. But this definition is incomplete and does not tell us how gas giants form or what ...

Key takeawaysIf a gas giant planet is big enough to ignite deuterium fusion, it becomes a brown dwarf instead of a planet.

A closer look at the planets around a star called LHS 1903 may just flip our understanding of how planetary systems form.
