For the first time, astronomers have directly mapped the surface of a rocky planet outside our solar system, and the result is stark: a scorched, pitch-black world with no atmosphere, no clouds, and ...

What can a 3D map of an exoplanet’s atmosphere teach astronomers about the planet’s formation, evolution, and composition? This is what a recent study published in Nature Astronomy hopes to address as ...

(Nanowerk News) Scientists using NASA’s James Webb Space Telescope have observed a rare type of exoplanet, or planet outside our solar system, whose atmospheric composition challenges our ...

Though long theorized to exist, the first exoplanet was detected in 1991. Since then, their known diversity has increased exponentially.

Using the James Webb Space Telescope (JWST), scientists observed the light coming from the exoplanet NGTS-10A b for 18 hours, ...

Conventional wisdom assumes the ratio of gases in a planet's atmosphere should match the ratio of gases in the natal disk that birthed it. For the first time, researchers compared gases in a ...
