Sunspot Activity Surges to a 23-Year High as Solar Maximum Defies ExpectationsSunspot activity on the Sun has reached its highest level in 23 years, with an average of 215.5 sunspots per day recorded ...
Sunspots are temporary, dark regions on the sun's surface caused by concentrated magnetic activity, which inhibits the flow of hot plasma and lowers their temperature compared to the surrounding ...
NASA explain: "Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s ...
During this active phase, the sun's magnetic field eventually snaps and completely flips, which triggers a falling-off period of solar activity and a decrease in sunspots until the whole cycle ...
On X, the space agency likened the shape of the flare and other activity observed on the Sun in the image to a smiley face.
The solar cycle refers to the 11-year period of solar activity from a maximum of observed sunspots through a minimum to a new maximum. The sunspots are the visible evidence of the solar magnetic ...
A planet-sized, magnetic dark spot on the sun, known as sunspot region AR3842, let out a massive burst of radiation on ...
The sun's magnetic activity—the origin of the solar wind and the resulting bright aurora displays—is calculated daily by counting sunspots on its surface. Sunspots are magnetic disturbances on ...
The Sun's impressive collection of sunspots implies that its period of peak activity, which likely began earlier this year, will be even livelier than originally thought. Having begun in December ...
CMEs are enormous clouds of solar plasma and solar magnetic field that are spat out of our star during periods of intense activity. CMEs are usually produced at sunspot regions and often accompany ...
Stunning Northern lights expected tonight and Friday After a major X-class solar flare erupted from the Sun late on Tuesday, ...
Authorities predict that states as far south as Oregon and Illinois will be able to see auroras between now and Oct. 6 ...
