The M4.4 solar flare unleashed a coronal mass ejection (CME) into space — and Earth might just receive a glancing blow.

The Mars Curiosity rover had to weather a solar storm. Specks seen in the video the rover captured are "caused by charged ...

Wednesday’s solar storm peaked around 4:25 a.m. ET, when the sun fired off a huge X-class flare, hurling streams of plasma and charged particles into the cosmos.

On May 10, 2024, Earth experienced the most powerful geomagnetic storm in over two decades. The storm, known as the Gannon Storm, was triggered by a series of massive solar flares and coronal mass ...

The sun has been active and unleashed an intense combination of coronal mass ejections and coronal hole high-speed streams with a geomagnetic storm forecasted for tonight, Aug. 7, and tomorrow, Aug. 8 ...

The exact timing of the CME’s arrival and how much of a geomagnetic storm will be produced remains to be seen.

The great solar storm of May 2024, which sparked beautiful auroral displays over much of the world, also created two new radiation belts that were observed with a satellite that came back from the ...

A coronal mass ejection hurtling from the sun toward Earth could unleash the northern lights in up to 18 states in the US.

The northern lights have creeped further south, but will Tennesseans be able to catch a glimpse of them again?

NASA’s Solar Dynamics Observatory captured this image of the Sun on May 7, 2024, in extreme ultraviolet light (at a wavelength of 304 Ångstroms). At center, the active region that instigated ...

NASA launches satellites to learn more about magnetic reconnection, which will help better predict geomagnetic storms.
