New research suggests that the unexpected intensity of the ongoing solar maximum may be partly tied to a lesser-known, 100-year solar cycle. If true, solar activity could spike further in the coming ...

Back in 2019, a consortium of scientists predicted August 2025 as the peak of the solar activity cycle. But where are we now? When you purchase through links on our site, we may earn an affiliate ...

Solar activity, manifested primarily through sunspots, solar flares and coronal mass ejections, has long influenced both the near-space environment and terrestrial systems. Over millennia, variations ...

The Northern Lights may ramp up in intensity for the next 50 years as the sun potentially enters a new long-term phase of heightened activity, suggests a new study by solar scientists. The night sky ...

Our sun is about five times less magnetically active than other sunlike stars—effectively a special case. The reason for this could reside in the planets in our solar system, say researchers at the ...

On December 8, 2025, the Sun unleashed a powerful solar flare, an event that captivated the attention of scientists and space enthusiasts alike. This flare, classified as an X1.1, marks one of the ...

A year ago this weekend, the sun’s activity created some of the most spectacular auroras on record, with displays visible as far south as Florida. The incredible spectacles last May (and another ...
