Of the thousands of single-star systems in our galaxy, around 10% are known to have planets. Scientists thus expected about ...

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

The atmospheres of exoplanets have been a focal point of the field lately, with the James Webb Space Telescope taking a look at as many as it can manage. But time on the world's most powerful space ...

Unlike large-scale space observatories such as the James Webb Space Telescope (JWST), EXCITE offers a cost-effective alternative for gathering critical data. This mission uses a unique approach, a ...

A mysterious object has caused a long-lasting and extreme dimming of a distant star, but is this object a 'failed star' brown ...

An exoplanet called HD 137010 b might be the closest thing astronomers have ever seen to “Earth 2.0.” The trouble is that it’s only been seen once—and may never be glimpsed again ...

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

The planet is one of the best worlds for follow-up studies to determine whether it could be habitable or not.

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 ...

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, ...

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 ...
