Activity on the sun is not constant; it varies along a cycle of about 11 years. The peak of this solar cycle — called solar maximum — is when sunspots, solar flares and coronal mass ejections (CMEs) ...

A powerful M8.1 solar flare sent a full-halo coronal mass ejection toward Earth, and scientists expect it to trigger strong G3 geomagnetic storm levels on Tuesday. Forecasts show the Kp index rising ...

A massive solar flare unleashed November 11 was one of the strongest on record, experts say—and the Earth-based fallout from weather on our closest star isn’t done yet. The flare—a powerful burst of ...

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 ...

A new study led by Southwest Research Institute (SwRI) links quasi-periodic pulsations (QPPs) in solar flares to dynamic oscillations in magnetic reconnection, a phenomenon that can drive space ...

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 clearest pictures ever taken of a solar flare have been taken by the world's largest solar telescope. Record-breaking images from the Daniel K. Inouye Solar Telescope in Hawaii reveal a flare four ...

Plasma astrophysicists at KU Leuven have created the first self-consistent simulation of the physical processes that occur during a solar flare. The researchers used Flemish supercomputers and a new ...
