A space telescope designed to look into the furthest-most reaches of space at some of the most energetic phenomena in the known universe has, once again, been turned to face our nearest star.
A giant eruption from the sun that scientists thought would hit Earth in 2014 missed because the sun's magnetic field channeled it away from the planet in an unexpected way.
After a long period of calm, the sun awoke from its slumber and erupted with one of the most powerful solar flares of the year on Tuesday.
When you block out the glare of the sun, usually invisible -- and beautiful -- phenomena pop into view.
This beautiful portrait of our nearest star was captured by NASA's Solar Dynamics Observatory (SDO), picking out the powerful and elegant loops of magnetized plasma reaching high into the sun's corona.
The most powerful solar storm of the current solar cycle is currently reverberating around the globe.
Jan. 19, 2015, was a red letter day for NASA's Solar Dynamics Observatory -- one of its instruments, having continually stared at the sun for 5 years, captured its 100 millionth observation of our nearest star.
Eruptions on the sun's surface are probably caused by giant, unstable magnetic plasma arches, a new study reports — a discovery that brings scientists one step closer to predicting solar outbursts that can wreak havoc on Earth.
