A furled model of the first starshade built by NASA’s Jet Propulsion Lab is shown in an Astro Aerospace/Northrup Grumman facility in Santa Barbara, California in 2013.

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

This slide explains some of the history of exoplanet detection over the last 30+ years.

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?

This slide compares the Kepler Space Telescope to the Transiting Exoplanet Survey Satellite (TESS) space telescope.

A series of images of a distant gas giant reveal its orbit around its star Beta Pictoris, located some 60 light-years from Earth.

The star appears to blink in a pattern. It dims like clockwork as six "hands" of differing size orbit around it at different rates.

When a planet passes directly between a star and its observer, it dims the star's light by a measurable amount. Light curves get complicated when more planets are transiting a star. The combined li...

Exoplanets can be pretty weird places, but do their names have to be so weird, too? Watch and learn how the scientific community determines and categorizes these unique planets.

Animation of a frozen planet, similar to worlds in our own solar system's Kuiper Belt.

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.

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

This slide explains the radial velocity method for exoplanet detection. 

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

Exoplanets – planets outside our solar system – are everywhere. At NASA, we're studying exoplanets to learn all about their weirdness, their variety, and all the fascinating things they can tell us...

The habitable zone is the distance from a star where one can have liquid water on the surface of a planet. If a planet is too close to its parent star, it will be too hot and water would have evapo...

The Kepler space telescope will remain for decades in orbit around the Sun, weaving in and out of Earth’s orbital path.

This video shows an artist's impression of the free-floating planet CFBDSIR J214947.2-040308.9.

Animation of HAT-P-7 light curve with magnified y-axis to better show the occultation dip in brightness. When the planet passes behind the star, light that is reflecting off the planet from the sta...

This animation shows the first-ever map of the surface of an exoplanet, or a planet beyond our solar system.

On this episode of Q&Alien, we talk about what the term "habitable zone" means - and what it doesn't.
