Astronomers have characterized the atmosphere of a young (20 Myr old) transiting exoplanet and found it to be unusually clear and puffy. By analyzing the planet's atmospheric features, they were able ...

Aerobraking is commonly used to slow down spacecraft when they arrive at various planetary systems. It requires a spacecraft to dip into the atmosphere of a celestial body in the planetary system, ...

Neptune’s auroras were expected near the poles, but James Webb found something far stranger. The discovery reveals how little ...

Researchers have shared a radical new idea for how to put a spacecraft in orbit around Neptune: Use the thin atmosphere of Triton, Neptune's largest moon, to capture it. When you purchase through ...

Astronomers have shown new atmospheric detail in a set of 15 exoplanets similar to Neptune. While none could support humanity, a better understanding of their behavior might help us to understand why ...

A team led by an astronomer from the University of Kansas has crunched data from NASA’s TESS and Spitzer space telescopes to portray for the first time the atmosphere of a highly unusual kind of ...

A tiny icy object orbiting beyond Neptune has surprised astronomers by displaying an atmosphere that, according to current ...

A strange dark spot on Neptune has been observed from Earth for the first time, offering fresh clues into how these marks form. In 1989, NASA’s Voyager 2 space probe detected a shadowy region on ...
