After a calm week, the sun erupted again. A powerful M5.1 solar flare burst from an emerging sunspot region, shaking the ...

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, ...

The Sun has just unleashed an M5-class solar flare, a powerful burst of radiation that signals a clear uptick in solar activity as the current cycle heads toward its peak. While this event is not the ...

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 ...

Climate data in a report published by the National Oceanic and Atmospheric Administration’s (NOAA) Climate.gov website found that the sun’s solar activity, including overall brightness and sunspot ...

Our sun has officially hit its solar maximum, with increased rates of auroras and solar flares expected in the coming months, NASA has announced. The sun goes through 11-year cycles of activity, ...

Thanks to a surge of solar activity, a round of northern lights could steal the show, giving skywatchers in up to 10 states a ...

New research suggests that the unexpected intensity of the ongoing solar maximum may be partly tied to a lesser-known, 100-year solar cycle. If true, solar activity could spike further in the coming ...

The sun’s solar weather has caused several atmospheric events since entering its solar maximum phase on Oct. 15, according to NASA. The phenomenon happens about every 11 years as the sun's shifting ...

Solar activity, manifested primarily through sunspots, solar flares and coronal mass ejections, has long influenced both the near-space environment and terrestrial systems. Over millennia, variations ...
