Researchers have provided some new insights about the powerful geomagnetic storm that flared up last Mother's Day, after a big solar storm hit Earth.

Scientists looked at Jupiter's massive auroras using the James Webb and Hubble Space Telescopes — and found a mystery they can't fully explain.

An 11-year Hubble study has finally revealed how long a day lasts on Uranus.

The sounding rockets released vapor tracers and pressure sensors at different altitudes across central and northern Alaska during a sudden auroral substorm.

The James Webb Space Telescope has successfully detected auroras on Neptune for the first time ever, finishing a job that NASA's Voyager 2 probe began decades ago.

Auroras are possible over the U.S. tonight (March 25) as a "moderate" geomagnetic storm hits Earth.

The gigantic coronal hole is blasting high-speed solar wind toward Earth, potentially igniting vibrant auroras and minor geomagnetic activity on Jan. 31.

NASA's LEXI instrument is set to land on the moon's surface sometime this month. Using X-ray sensors, the device will watch Earth's atmosphere "breathing out and breathing in" to uncover key space weather mysteries.

Last year, Earth spewed charged particles into the sun in a rare cosmic event that has surprised scientists.
