How can astronomers observe and study the Sun’s activity in the most efficient way despite the Sun and Earth orbiting each ...

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

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, ...

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

The Sun's activity is what gives us beautiful auroras — but it also has dramatic negative effects on satellites that go around Earth in a low orbit. When you purchase through links on our site, we may ...

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, ...
