Sunspots are temporary, dark regions on the sun's surface caused by concentrated magnetic activity, which inhibits the flow of hot plasma and lowers their temperature compared to the surrounding ...

Sunspots are the most striking phenomenon of the solar magnetic field. After the invention of the telescope early in the 17th ...

Two new sunspots have ended a long period of relative quiet on the surface of our blazing host star, heralding the start of a new 11-year cycle of sunspot activity.

Sunspot activity has been in the past seven decades than at anytime in the past 8,000 years, according to a new study that provides the best historic reconstruction ever made of solar activity.

Higher solar activity brings more radiation, which can damage satellite electronics and force some satellites to deorbit ...

Sunspot and solar flare activity, which can disrupt communications and electrical systems on Earth, will increase until a peak sometime between 2023 and 2025.

Climate skeptics early on used intense sunspot activity in the 20th century to explain a rise in global temperatures - much to the chagrin of mainstream scientists.

The sun is most likely going into hibernation as the latest unusual solar readings, including fading sunspots and weakening magnetic activity near the poles suggest that we are headed towards a solar ...

Sunspots have long been used by climate skeptics to explain away a rise in global temperatures. They argued that solar activity appeared to trend upwards over the past 300 years, on pace with ...

Top: Reconstructed sunspot activity (10 year average) for the last 11,400 years based on C-14 data (blue curve) and the directly observed historical sunspot data since 1610 (red curve). The reliable C ...

While sunspot activity may indeed play somewhat of a role in this quiet hurricane season so far, it is likely just one of many contributing factors that scientists continue to study and try to ...
