Solar activity waxes and wanes on an 11-year cycle. The current cycle, known as Solar Cycle 25, began in December 2019 and is still in its maximum phase, experts say. "Currently, we're about two ...

We are currently in Solar Cycle 25, which began in December 2019, and are now in the grips of this cycle's solar maximum—and ...

A surprise announcement from scientists involved in monitoring the solar cycle has finally confirmed that the sun's most ...

Scientists at NASA and NOAA think the sun has reached the maximum phase of the solar cycle, which means another year — at least — of intense Northern Lights.

In this instance, with such an intense amount of ultraviolet (UV) radiation that accompanied the flare, a shortwave radio ...

After reaching solar maximum in Solar Cycle 25, the Sun continues producing multiple solar flares, with some Earth-directed ...

“Solar Cycle 25 sunspot activity has slightly exceeded expectations,” said Lisa Upton, co-chair of the Solar Cycle Prediction Panel. “However, despite seeing a few large storms, they aren ...

The last solar max in 2014 — Cycle 24 — was the fourth-least intense since Cycle 1 in 1755. Prospects didn't look much better for the current Cycle 25 a few years back. But the sun has ...
