Total solar irradiance (TSI), essentially a measure of the amount of light the Sun puts out, varies with the 11-year sunspot cycle and influences Earth’s climate, especially when TSI is notably higher ...

In a new study published in The Astrophysical Journal Letters, NASA researchers reveal that the Sun — long believed to be drifting into a historic lull — has instead been ramping up its activity since ...

A new NASA computer climate model reinforces the long-standing theory that low solar activity could have changed the atmospheric circulation in the Northern Hemisphere from the 1400’s to the 1700’s ...

For example, between 1645 to 1715 the Sun experienced a pronounced period of low activity known as the Maunder Minimum, and the same is true between the years 1790 and 1830 (a.k.a. the Dalton Minimum) ...

The sun has been quiet for the past couple of years. Too quiet. Normally, our home star goes through a sort of rising and falling sleep-wake cycle that lasts 11 years, on average. At the so-called ...
