Solar flare

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.

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

The sun has released several powerful M- and X-class solar flares over the past few days, resulting in radio blackouts around the world.

A powerful X1.1-class solar flare was released by the sun on March 28, resulting in radio blackouts across North and South America

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

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.

Observations made using a new method have revealed that sun-like stars produce cataclysmic superflares once every hundred years. Could our sun create one soon?

The sun just unleashed one of its largest solar explosions in recent years, temporarily causing a radio blackout on Earth and spitting out a coronal mass ejection that will likely collide with our planet this weekend.

A 'rule-breaking' sunspot has fired off an extremely powerful X-class solar flare, launching a CME toward Earth that could bring vibrant weekend auroras.

Three powerful solar eruptions could bring auroras as far south as New York and Idaho right at the peak of the Perseid meteor shower this weekend.
