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.

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 ...

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, ...

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

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 ...

The Sun seems like a perfectly reliable, unchanging presence in the daytime sky, but it’s not. Intense heat and pressure in its core fuses hydrogen atoms into helium, fueling the cosmic fire that ...

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 ...

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 ...

NEW ORLEANS (WVUE) - An uptick in strong solar activity could create a severe solar storm, bringing the Northern Lights as far south as Alabama and northern California. The sun produced an X5.1 flare ...

The sun has become more and more active over the last 16 years, in a turn that surprised scientists and could affect space weather and technology on Earth, NASA announced this week. A new research, ...
