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?

Some telescopes capture starlight shining through the atmospheres of exoplanets. Gases in these atmospheres can then be revefaled.

Space telescopes have pioneered the discovery of planets orbiting other stars in our galaxy; even more powerful versions will measure these planets' atmospheres in the future.   

Every star has a habitable zone, but where that zone lies is different for stars of different sizes and brightness.

When we describe different types of exoplanets – planets outside our solar system – what do we mean by "hot Jupiters," "warm Neptunes," and "super-Earths"? 

Acechando en nuestra galaxia, a aproximadamente 6.000 años luz de la Tierra, hay un monstruo llamado Cygnus X-1.
