Exoplanets, by definition, exist outside our solar system, orbiting other stars. That means they’re pretty far away. Telescopes, even top-notch ones like Hubble, can’t image anything as small as a ...

Astronomers have discovered a new exoplanet — but this time, the way they found it may be as significant as the discovery itself. Researchers used a breakthrough combination of indirect and direct ...

Since the discovery of the first exoplanet in 1992, astronomers have been on the hunt for these alien worlds, finding thousands of them all over the cosmos. But there are some that — though they ...

The NEID instrument mounted on the 3.5-meter WIYN telescope at the Kitt Peak National Observatory. The NASA-NSF Exoplanet Observational Research (NN-EXPLORE) partnership funds NEID (short for ...

The search for new planets outside the solar system, also known as exoplanets, is one of the most fascinating and interesting challenges that astrophysics research has been facing in recent years.

For centuries, planets beyond our solar system—called exoplanets—existed only in theory and science fiction. It seemed nearly impossible to detect planets light-years away, since the relatively tiny ...

Astronomers are on the hunt for alien life outside of our Solar System. More than 4,000 exoplanets have been discovered in recent years, but we don’t yet know if any of them have all the key ...

It was almost 100 years ago that Clyde W. Tombaugh discovered Pluto. That was the last planet found until 1992, when humans found another one. But this new planet wasn't in our solar system—it was ...

As the first successful technique used to detect exoplanets orbiting distant stars, the radial velocity method aims to detect a periodic Doppler shift in a stellar spectrum due to the star's motion ...

Artist’s rendition of variety of exoplanets featured in the new NASA TESS-Keck Survey Mass Catalog, the largest, single, homogenous analysis of TESS planets released by any survey thus far. The study ...
