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, ...

BOULDER–Challenging conventional wisdom, new research finds that the number of sunspots provides an incomplete measure of changes in the Sun’s impact on Earth over the course of the 11-year solar ...

Every eleven years, the sun's magnetic field flips. Sunspots—dark, cooler regions on the sun's surface that mark intense ...

At the end of the last solar cycle in 2019, the official predictions were that the next cycle would be just as mild as its predecessor. Those predictions were wrong. The current Solar Cycle 25 turned ...
