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 ...

AI Reveals Patterns in Solar Activity In their study, Guastavino and her team used machine learning to analyze historical solar activity data, training their algorithms on decades of solar ...

By historical definition, Solar Cycle 1 occurred between 1755 and 1766, placing the sun 's current cycle in Solar Cycle 25. As of the end of 2024, we are firmly within the solar maximum period.

The highest sunspot number in modern history was recorded in October 1957, where 359.4 sunspots were seen on average just before the maximum of Solar Cycle 19, while the highest number on record ...

The sun released an enormous explosion of radiation on Thursday, which is barreling through space. The solar flare is set to hit our planet Friday, triggering auroras in skies over several US states.

The Old Farmer's Almanac's 2025 fall prediction read: "Your trek to the pumpkin patch may be a bit steamy this year. The Old ...

The new theory suggests that the 80—to 100-year cycle may be more accurate in determining the active sun spot activity than the previously thought of 11-year cycles. That would mean the new ...

Scientists have released the closest images ever to the sun, captured by NASA’s Parker Solar Probe flying 3.8 million miles above the solar surface.

By examining ancient ice cores, scientists are able to obtain accurate dates for spikes in Be-10 (and other related isotopes), which can then be used to track historic solar activity.
