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

While the Sun’s solar flares strongly correlate with sunspots, observations of more than 14,000 other stars show this is not generally the case.

Climate data in a report published by the National Oceanic and Atmospheric Administration’s (NOAA) Climate.gov website found that the sun’s solar activity, including overall brightness and sunspot ...

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

The Sun seems like a perfectly reliable, unchanging presence in the daytime sky, but it’s not. Intense heat and pressure in its core fuses hydrogen atoms into helium, fueling the cosmic fire that ...

'Dilbert' creator Scott Adams dies at 68 after prostate cancer battle Actor Kiefer Sutherland arrested for allegedly ...

Not only did we witness some big storms on Earth in 2025, but the sun also put on a show for the country, fuelling a number ...

Solar physicists say they have found a key source of intense gamma rays unleashed when Earth's nearest star produces its most ...

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 ...

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 ...
