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

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 ...

Helium can help scientists detect the speed and direction at which we’re moving through space. Deuterium, which is left over ...

Flickering coronal "loops" on the Sun are warning signs of a coming solar eruption, paving the way for better space weather ...

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 ...

Solar flares are sudden ... The researchers hope that these flickering variations of the coronal loops could be between 60 to 80 percent accurate in predicting the occurrence of a flare in ...

A solar cycle: a montage of ten years of Yohkoh SXT images, showing the variation in solar activity over a solar cycle, from August 30, 1991, to September 6, 2001. Credit: the Yohkoh mission of ISAS ...

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 ...
