Astronomers may finally understand why planets orbiting two suns, the real-world equivalents of the "Star Wars" planet ...

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 ...

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 ...

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

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 tiny star is making big moves — whether its accomplice likes it or not. Astronomers have spotted a star just a fraction the mass of the Sun crashing through the Milky Way at an unbelievable pace.

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 ...
