A new study offers key insights into Mars' water cycle.

The James Webb Space Telescope has turned its infrared eyes toward Jupiter, capturing auroras hundreds of times brighter than those on Earth glowing on the gas giant's poles.

It's been one year since the historic Gannon Storm lit up the night sky with auroras and piqued interest in space weather. Here's what experts say we learned from the historic event.

A first-of a-kind space weather "tabletop" exercise has revealed major weaknesses in America's preparedness for major solar storms.

A new image from Europe's Copernicus Sentinel-3 satellite shows the huge Antarctic iceberg A-23A stuck 45 miles (73 kilometers) off the coast of South Georgia Island.

After a pair of satellites failed to reach their desired orbit around the moon last year, China used a novel gravity "slingshot" tactic to get the satellites in the correct spot.

NASA is no longer asking U.S. companies for proposals to get the ice-hunting VIPER rover to the moon but still hasn't given up on the mission.

Earth's atmosphere pulses in sync with the sun's fiery outbursts, indicating it is more sensitive to solar activity than previously thought, according to new research.

The moon spent a few million years as a volcanic wasteland, covered with ongoing eruptions that spewed from mountains and even from the ground itself.
