This discovery is out of this world. For the first time since its operations began in 2021, the James Webb Space Telescope (JWST) has captured a direct image, published by the journal Nature, of a new ...

With sapphire waterfalls, lava rain and orbits around dead stars, these distant worlds push the limits of what’s possible.

The astronomical confusion started at 2 a.m ET on June 26, 2023. Scientists using the powerful James Webb Space Telescope sought to observe a planet beyond our solar system (an exoplanet) called ...

A newly discovered exoplanet is rewriting the rules of what planets can be. Orbiting a city-sized neutron star, this ...

Astronomers at the University of Cambridge in England announced on April 17 that they had found the strongest evidence yet that life may exist somewhere besides Earth. Using data from NASA's James ...

A team of astronomers using the James Webb Space Telescope have detected biosignatures in the atmosphere of a possible ocean world 124 light-years from the solar system. The scientists behind the ...

Astronomers have detected over 5,800 confirmed exoplanets. One extreme class is ultra-hot Jupiters, of particular interest because they can provide a unique window into planetary atmospheric dynamics.

Although we already know dozens of exoplanets without their own star, their masses could only be estimated. Now a precise ...

New discoveries and fresh looks at familiar worlds show how far exoplanet science has come — and how much remains unknown. When you purchase through links on our site, we may earn an affiliate ...

Exoplanets are planets outside Earth's solar system. In 1995, a gas giant named 51 Pegasi b, which orbits a star similar to Earth's sun, etched its name in history as the first exoplanet ever ...
