The existence of the planet, named AT2021uey b, took years to verify. Astronomers have located a rare exoplanet on the edge of the Milky Way. The exoplanet, a gas giant named AT2021uey b, orbits a low ...

This year, the number of NASA-tracked confirmed worlds discovered beyond our solar system surpassed 6,000, and several thousand more await confirmation. The growing tally reflects how dramatically ...

The balloon-based EXCITE mission measures infrared phase curves of hot Jupiter exoplanets to map temperature and atmospheric composition from long-duration Antarctic flights.

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 ...

An exoplanet called HD 137010 b might be the closest thing astronomers have ever seen to “Earth 2.0.” The trouble is that it’s only been seen once—and may never be glimpsed again ...

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 ...

Using the Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new exoplanet orbiting a nearby star. The newfound alien world, designated TOI-2431 b, is ...

The interstellar visitor may still have a few things to tell us before it leaves our solar system.

Just decades after the first exoplanets were identified, our database of the distant worlds—monitored by the NASA Exoplanet Science Institute—has breached a new threshold. Now, astronomers have ...

The team of astronomers behind the find suggested it could help us better understand planet and moon formation in our solar system and beyond the Milky Way. The team was able to make the first-ever ...

At the beginning of the exoplanet age, the goals were fairly simple. The first was to find as many of them as possible to flesh out our understanding of the exoplanet population. The second was to ...
