NASA captured an image of an intense solar flare released by the sun on Tuesday evening. The solar flare peaked at 5:49 p.m. EDT on Tuesday, NASA's Solar Dynamics Observatory said. It was an X-class ...

An X-class solar flare has produced an Earth-directed coronal mass ejection, increasing solar activity and raising the likelihood of geomagnetic impacts within 24 hours.

The sun has emitted a powerful solar flare that has the capability to interfere with technology on Earth. The explosive burst of radiation peaked on the evening of June 17, matching the intensity of ...

Our planet was rocked by some of the worst geomagnetic storms in more than 20 years. Triggered by a slew of solar flares, the storms disrupted satellites, power grids, and GPS and cast the northern ...
