Our sun has officially hit its solar maximum, with increased rates of auroras and solar flares expected in the coming months, NASA has announced. The sun goes through 11-year cycles of activity, ...

The agencies that track sunspot activity say we’re now in peak solar activity, which has a big impact on the amount and southward extent of the Northern Lights. On Oct. 15, 2024 NOAA, NASA and the ...

A whopping sunspot that is getting larger and crackling with activity threatens to flash powerful solar flares in our planet's direction. The sunspot, named AR3780, appears to be getting bigger and ...

Sunspots are the visible component of active regions, areas of intense and complex magnetic fields on the Sun that are the source of solar eruptions. “During solar maximum, the number of sunspots, and ...

The sun is powered by the nuclear fusion of hydrogen to helium, deep within its core. Above the sun's surface, however, a different force dominates: electromagnetism. This force is responsible for ...
