Thanks to the sun, we're in the middle of the best time to see the northern lights — and maybe the worst time to be a satellite. NASA announced Tuesday that the sun is in the "maximum phase" of its 11 ...

Artist’s concept of Parker Solar Probe. On Tuesday, Dec. 24, NASA's Parker Solar Probe got to within just 3.86 million miles (6.1 million kilometers) of the sun's surface. NASA’s Parker Solar Probe ...

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 has become increasingly active since 2008, a new NASA study shows. Solar activity is known to fluctuate in cycles of 11 years, but there are longer-term variations that can last decades. Case ...
