For the first time, scientists have used satellite data to create a 3D map of the sun's interior magnetic field, the ...

Northern lights occur when a solar flare interacts with Earth's atmosphere.

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.

A high-resolution image of the flare from the Inouye Solar Telescope, taken on August 8, 2024, at 20:12 UT. The image is about 4 Earth-diameters on each side. “This is the first time the Inouye Solar ...

Earth’s magnetic field was rattled by a solar outburst that arrived with almost no warning, lighting up skies and briefly reminding power grid operators and satellite controllers how vulnerable modern ...

After weeks of reduced activity, the sun erupted with three powerful flares on a single day. That could send solar flares toward Earth, impacting electronics and making it possible to view the ...

The sun is not a static, tranquil sphere of gas, but an active, turbulent star with magnetic fields that twist and snap in powerful eruptions. Among the most striking and energetic of these eruptions ...

This was the view as a multi-colored curtain of aurora formed to the south in my sky during the great display of Northern Lights on May 10, 2024. The Kp Index peaked at 8 this night bringing the ...

The Van Allen radiation belts, massive regions of charged particles trapped by Earth's magnetic field, have become "fully charged" due to repeated solar storms. A space weather observer warns that the ...

Referred to as a “stealth storm,” a recent coronal mass ejection went undetected until it hit Earth. Stealth coronal mass ejections are more common after the Sun transitions from the solar maximum to ...
