5,000 Exoplanets: Listen to the Sounds of Discovery (360 Video)
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.
NASA Confirms 5,000 Exoplanets -- and Counting
What do planets outside our solar system, or exoplanets, look like? A variety of possibilities are shown in this illustration.
Exoplanet Types - 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.

Lanzado en 1990, el telescopio espacial Hubble es un gran observatorio espacial que ha revolucionado la astronomía.
El Telescopio Espacial Hubble
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.
Marble in the Sky: the Hunt for Another 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"?

Scientists using NASA’s Hubble Space Telescope have found evidence that a planet orbiting a distant star may have lost its atmosphere but gained a second one through volcanic activity.
Distant Planet May Be On Its Second Atmosphere, NASA's Hubble Finds
A rocky exoplanet GJ 1132 b, similar in size and density to Earth, possesses a hazy atmosphere made up of volcanic gases. Scientists say GJ 1132 b, orbiting a red-dwarf star about 41 light-years aw...
A Super-Earth With Plenty of Atmosphere
For a planet, the habitable zone is the distance from a star that allows liquid water to persist on its surface – as long as that planet has a suitable atmosphere.
