Scientists used the James Webb Space Telescope to observe the exoplanet WASP-18 b and its star before, during and after the planet was eclipsed. 

Researchers made a brightness map, tracing the glow from hot regions of WASP-18 b as it slipped behind, and reappeared from, its star.

The Webb Telescope directly observed water vapor on WASP-18 b, a gas giant exoplanet, in even relatively small amounts in an atmospheric spectrum.

WASP-18 b is a gas giant exoplanet 10 times more massive than Jupiter that orbits its star in just 23 hours. Researchers used NASA’s James Webb Space Telescope to study the planet as it moved behin...

We've wanted to study the TRAPPIST-1 exoplanets with the James Webb Space Telescope since its Christmas Day launch in 2021. We expect to see new science on the planets in the coming year.

Possible characteristics of clouds in exoplanet atmospheres that could be captured by NASA's James Webb Space Telescope.

NASA's James Webb Space Telescope will reveal secrets of clouds in the atmospheres of exoplanets – planets beyond our solar system.

A transmission spectrum made from a single observation from the Webb Space Telescope reveals atmospheric characteristics of the hot gas giant exoplanet WASP-96 b. 

El Conjunto de Telescopios Espectroscópicos Nucleares (NuSTAR, por sus siglas en inglés), complementa otras misiones astrofísicas de la NASA que estudian el universo en diversos espectros, mediante...

NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, explores our universe with its X-ray vision.

On March 21, 2022, the number of known exoplanets passed 5,000 according to the NASA Exoplanet Archive. This animation and sonification tracks humanity's discovery of the planets beyond our solar s...

This 360-degree animation and sonification tracks humanity's discovery of the planets beyond our solar system over time.

NASA has confirmed more than 5,000 worlds beyond our solar system during 30 years of exploration. There are billions of exoplanets in our galaxy alone, so many more discoveries await.

What do planets outside our solar system, or exoplanets, look like? A variety of possibilities are shown in this illustration. 

The more than 5,000 exoplanets confirmed in our galaxy so far include a variety of types – some that are similar to planets in our solar system, others vastly different.

¿Puedes oír los gritos de este exoplaneta?

Can you hear this exoplanet screaming?

¡Esta fuerza escalofriante te dejará temblando de terror!​

This bone-chilling force will leave you shivering alone in terror!

El telescopio espacial James Webb de la NASA es una verdadera maravilla tecnológica.

The James Webb Space Telescope is the world's premier space science observatory. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the myste...

In space for more than 30 years, Hubble truly is NASA’s most versatile, intrepid explorer. It brought the cosmos down to Earth.

Lanzado en 1990, el telescopio espacial Hubble es un gran observatorio espacial que ha revolucionado la astronomía.

In this artist's concept, a distant, life-bearing world orbits two stars instead of one, seen from the surface in a pink sky – yet in some ways still might be considered similar to Earth.

There are water worlds, lava planets, egg-shaped worlds, planets with multiple suns, and even planets with no sun at all! What can we learn from this weird, wondrous variety?
