Back in 2019, a consortium of scientists predicted August 2025 as the peak of the solar activity cycle. But where are we now?

On May 29, 2020, a family of sunspots — dark spots that freckle the face of the Sun, representing areas of complex magnetic fields — sported the biggest solar flare since October 2017. Although the ...

The sunspot patch that caused the early May auroras is again active. Formerly AR 3664, the area generated three X-class flares, including the most powerful of the solar cycle, before spinning out of ...

The largest geomagnetic storm since 2003 that occurred last Friday may be just the beginning of a more intense than expected period of solar activity. More explosions of energy and light occurred in ...

Once-rare displays of Northern Lights at southerly latitudes look set to continue for the foreseeable future as scientists confirmed that August saw the sun at its most active for 23 years. The sun's ...

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 ...

Astronomers in Arar have spotted massive sunspots reaching incredible sizes, impacting solar activity and Earth’s communication systems. Discover the effects and significance of these cosmic phenomena ...

A sunspot so large it was seen from the surface of Mars is now facing Earth. The gargantuan sunspot group AR3576 from end to end stretches for more than 124,274 miles (200,000 kilometers) and contains ...

In recent months astronomical observatories have frequently reported huge, black spots marching across the face of the sun, seriously disturbing some kinds of radio transmission on Earth. Sunspot ...
