This year has given stargazers plenty of opportunities to catch the colorful auroras of the northern lights flicker across the night sky, and that's expected to continue as the sun is now in its solar ...

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.

Massive solar flares, graceful eruptions of solar material, and an enormous sunspot make up some of the imagery captured by NASA's Solar Dynamics Observatory in 2013 and 2014. A year ago this weekend, ...

Researchers have discovered a new relationship between the Sun's magnetic field and its sunspot cycle, that can help predict when the peak in solar activity will occur. Their work indicates that the ...

In a new weekly update for pv magazine, Solcast, a DNV company, explains that the solar cycle does tend to increase the earth’s average annual extra-terrestrial irradiance, but only by a very small ...

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

The colossal ball of hot gas at the center of our solar system will be lively for the next year, NASA said. The sun has reached its "solar maximum period," which is a state of heightened activity in ...

The sun is quickly approaching a major peak in solar activity. Experts warn it could potentially begin by the end of 2023, years before initial predictions suggested. When you purchase through links ...
