By tracing solar flare gamma rays, scientists gain new insight into particle behavior that shapes space weather forecasts.

Watch this one-week time-lapse of the coronal hole in the Sun's atmosphere from NASA's Solar Dynamics Observatory. Amazing ...

Solar wind speeds remain elevated as an incoming coronal mass ejection approaches Earth, with forecasts indicating increased ...

A coronal mass ejection from the X-5 class flare, the strongest flare of solar cycle 25, will likely trigger geomagnetic storms when it hits Earth. When you purchase through links on our site, we may ...

A recent coronal mass ejection may disrupt Earth’s geomagnetic field on Friday, potentially making the aurora borealis ...

Coronal loops, well-defined hot strands of plasma that arch out into the sun’s atmosphere, are iconic to the sun’s imagery. But many of the supposed coronal loops we see might not be there at all.

Two huge coronal holes, dozen of times the size of the Earth, have appeared on the sun. These have been spewing fast solar winds toward Earth as fast as 1.8 million mph. Experts explain what they are ...

Michael Hahn and Daniel Wolf Savin from Columbia University’s Astrophysics Laboratory in New York found evidence that magnetic waves in a polar coronal hole contain enough energy to heat the corona ...

Some of the most spectacular features on the Sun are its coronal loops — incandescent structures of hot plasma that arc for thousands of miles above magnetically active regions of the Sun, forming ...
