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

The Sun seems like a constant, reassuring presence day to day, but it's actually fairly tempestuous and changeable. One particular change it undergoes is what we call the solar cycle. Every 11 years ...

The sun has become more and more active over the last 16 years, in a turn that surprised scientists and could affect space ...

Major power and communications disruptions could happen on Monday as Earth grapples with an avalanche of solar storms. At least 11 states are expected to be affected by Monday's solar activity: Alaska ...

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 ...

The sun is in its most active phase—solar summer—causing auroras and posing real risks to satellites, GPS, and power systems ...

With advance warning, however, steps can be taken to reduce the risks. If an electrical grid is running near capacity, for ...

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 ...

Cosmic rays, consisting predominantly of high-energy protons and nuclei originating from distant astrophysical sources, interact continuously with the solar wind and the heliospheric magnetic fields.
