WASP-121 b is the definition of an "extreme" exoplanet — it's so hot that it rains droplets of liquid iron. Now, astronomers have discovered that this planet, located around 900 light-years away from ...

This discovery is out of this world. For the first time since its operations began in 2021, the James Webb Space Telescope (JWST) has captured a direct image, published by the journal Nature, of a new ...

An exoplanet discovered in 2020 contains the coldest temperatures ever measured on a planetary body, according to scientists. The planet, called WD 1856+534 b, is a gas giant exoplanet the size of ...

Astronomers have detected over 5,800 confirmed exoplanets. One extreme class is ultra-hot Jupiters, of particular interest because they can provide a unique window into planetary atmospheric dynamics.

Exoplanet habitability depends on a whole host of factors, with liquid water at the top of the list. It also requires a stable atmosphere, the right chemistry, and possibly even things like plate ...

"Until we can separate these signals more clearly, we have to be especially careful not to misinterpret them as signs of life." In 2023, scientists from Cambridge University reported what appeared to ...
