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) ...

New images of the sun captured by the Solar Orbiter mission showcase the highest-resolution views of our star’s visible surface ever seen, revealing sunspots and continuously moving charged gas called ...

Massive solar flares, graceful eruptions of solar material, and an enormous sunspot make up some of the imagery captured by NASA's Solar Dynamics Observatory in 2013 and 2014. A year ago this weekend, ...

New research suggests that the unexpected intensity of the ongoing solar maximum may be partly tied to a lesser-known, 100-year solar cycle. If true, solar activity could spike further in the coming ...

There were significantly more X-class solar flares in 2024 than any other year for at least three decades. The arrival of solar maximum was a key reason for the spike, but other factors were also at ...
