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 ...

A powerful solar flare erupted from the sun on November 14, 2025, causing radio blackouts across parts of Africa. This X4-class flare, the second-strongest of the year, originated from a highly active ...

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 ...

You could get more opportunities to see supercharged auroras over the next few months, thanks to our very active sun. Solar activity waxes and wanes on an 11-year cycle. The current cycle, known as ...

Establishing a key link between the solar cycle and global climate, new research led by the National Center for Atmospheric Research (NCAR) shows that maximum solar activity and its aftermath have ...

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 ...

During strong cycles, the sun’s total brightness at the solar maximum is about 0.1% higher than during its solar minimum, but when averaged out over the industrial period, the sun’s total brightness ...

There may be more northern lights – or aurora borealis – sightings this spring. As we near the spring equinox, also known as the vernal equinox, on March 20, the Earth's magnetic field and solar wind ...

Last month, Earth was treated to a massive aurora borealis that reached as far south as Texas. The event was attributed to a solar storm that lasted nearly a full day and will likely contend for the ...
