Exoplanets

The exoplanet telescope TESS revealed a distant world using an entirely different detection method than the one it was built around

Astronomers have for the first time observed an atmosphere around a giant planet orbiting a white dwarf

A cold, cherry-blossom-hued exoplanet supports bizarre clouds chock-full of salts

Planets might exist in the least likely place you’d imagine—around the outskirts of supermassive black holes

An out-of-this-world weather report from NASA’s James Webb Space Telescope reveals how clouds move across a giant planet hundreds of light-years from Earth

Ahead of schedule and under budget, the Nancy Grace Roman Space Telescope will launch in early September. The mission aims to map the universe in unprecedented detail

Rather than slowly condensing over millions of years, the first building blocks of Earth and other planets may have formed rapidly in a chaotic disk at the dawn of the solar system

The decades since scientists confirmed the first planet around another star have been rich in discovery, but it’s rare to see a new solar system as it forms

Although astronomers have found thousands of exoplanets, the number of confirmed exomoons—and exorings—is still zero. But that may soon change

Fresh observations from the James Webb Space Telescope show how vivid auroras surge through Uranus’s tilted magnetic field

Four worlds around a small, dim star are challenging theories of planet formation

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
