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

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, ...

The sun typically goes through regular cycles of increased and decreased activity, but in recent years, it hasn't been ...

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 ...

Activity on the sun is not constant; it varies along a cycle of about 11 years. The peak of this solar cycle — called solar maximum — is when sunspots, solar flares and coronal mass ejections (CMEs) ...

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 ...

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 ...

Using the combined might of spacecraft scattered across the Solar System, scientists have built the most detailed map yet of ...

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 ...

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, ...

People in the U.S. were treated to stunning auroras last week when a powerful geomagnetic storm pushed the celestial displays as far south as Florida and Mexico. The spectacle was particularly ...
