It’s notoriously difficult to predict when the sun will belch out a large solar flare — an explosive burst of radiation that ...

Earth’s elliptical orbit causes slight variations in solar energy, with about 7% more sunlight reaching Earth during perihelion than aphelion. So, is Earth hotter in January than in July?

Scientists have long struggled to accurately predict solar flares, but a recent breakthrough using NASA’s Solar Dynamics Observatory has uncovered a promising new sign: flickering coronal loops. These ...

Solar radiation variability is a critical factor in understanding climate change and its impacts on energy production, particularly solar energy. Recent research has focused on how changes in air ...

If everything in our solar system formed from the same solar nebula, why do the planets have different compositions? Herbert WichTitusville, Florida To better understand why the planets have variable ...

The Sun's activity was observed by NASA's Solar Dynamics Observatory (SDO) spacecraft. Its mission is to study the Sun’s ...

Conventional models for solar, for example, often reduce variability to a yearly average. “It was not as important when renewable wind and solar were only 5% of all energy sources but that is ...
