Solar Orbiter observations show that a medium-class solar flare formed through cascading magnetic reconnection events, ...

Every two seconds, the camera on board Solar Orbiter is able to freeze the corona on another frame, and in this rare data set, it has captured the early, quiet failures that can build into a major ...

"This is one of the most exciting results from Solar Orbiter so far." ...

Scientists watched a solar flare grow from tiny magnetic sparks into a violent plasma-raining avalanche on the Sun.

Deep in the core of most galaxies, hidden by spinning clouds of gas and dust, black holes spin like cosmic engines. These giants — some are billions of times heavier than our sun — can shoot out ...

"This is the largest solar radiation storm in over 20 years," the Space Weather Prediction Center said on Monday.

NASA’s Magnetospheric Multiscale is delivering promising early results on a process called magnetic reconnection – a kind of magnetic explosion that’s related to everything from the northern lights to ...

NASA’s Solar Dynamics Observatory has observed a magnetic explosion the likes of which have never been seen before. In the scorching upper reaches of the Sun’s atmosphere, a prominence — a large loop ...

But for the past several years, scientists have known of a mystery in the magnetotail: a missing storm. They have found a signature of a storm, but no storm to actually go along with it. NASA’s ...

Our Sun’s outer atmosphere, the corona, is millions of degrees hotter than it should be, and no one knows why.
