Jupiter’s upper atmosphere is hundreds of degrees warmer than expected. After a decades-long search, scientists may have pinned down a likely source of that anomalous heat. The culprit, a new study ...

There is a paradox at the heart of our changing climate. While the blanket of air close to the Earth’s surface is warming, most of the atmosphere above is becoming dramatically colder. The same gases ...

A storm from the Sun can make a planet’s sky glow or a spacecraft’s computer fail. On Mars on May 2024, it did both, just ...

Uranus, named after the Greek sky god, was discovered in 1781, becoming the first planet identified with a telescope. Despite ...

Researchers have detected measurable traces left in the upper atmosphere when a rocket stage burns up, finding about ten ...

Rising concentrations of carbon dioxide in the upper atmosphere will change the way geomagnetic storms impact Earth, with potential implications for thousands of orbiting satellites, according to new ...

Nearly 30 years ago, scientists in aircraft miles above the ground finally managed to capture a phenomenon never before confirmed on film. This flash of red light, lasting no longer than a few ...

A team led by the University of Colorado Boulder has found the mechanism behind the sudden onset of a “natural thermostat” in Earth’s upper atmosphere that dramatically cools the air after it has been ...

A growing body of peer-reviewed research shows that rocket launches and satellite reentries are depositing pollutants ...

A new phase of the space race is unfolding far above Earth, but its effects may not stay there. Satellite launches have increased sharply recently, la.

NASA's James Webb Space Telescope has captured the first vertical view of Uranus's upper atmosphere, delivering an unprecedented look at the planet's ionosphere and auroral structures. The new ...

Saturn’s upper atmosphere and ionosphere constitute a complex system in which neutral and charged particles interact under the influence of external energy inputs, internal dynamics and ...
