Solar wind speeds remain elevated as an incoming coronal mass ejection approaches Earth, with forecasts indicating increased ...

After a calm week, the sun erupted again. A powerful M5.1 solar flare burst from an emerging sunspot region, shaking the stillness of space weather and igniting new forecasts of heightened activity.

Has the Sun’s activity increased or decreased in the last few years? This is what a recent study published in The Astrophysical Journal Letters hopes to address as a team of scientists investigated ...

One way to track the solar cycle is by counting the number of sunspots, which are dark, cooler patches on the Sun’s surface.

What: A major coronal hole on the Sun is releasing high-speed solar wind toward Earth, driving recent auroral activity and space weather disturbances. Coronal holes are cooler regions where the Sun’s ...

Did two vast holes really open up on the Sun and point directly at Earth? We unpack whether Earth is facing serious space ...

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 ...

EIA’s latest monthly “Electric Power Monthly” report (with data through July 31, 2025), once again confirms that solar is the fastest growing among the major sources of US electricity. In July alone, ...
