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 sun has erupted with its first X-class solar flare of 2015, a not-so-subtle reminder that it can still muster the energy required to generate the most powerful class of solar explosion.
On Earth, the sun usually looks like an orange blob or a yellow blob, depending on the time of day. Fascinating, sure, but - a blob. If you want to take the boring out of the sun, you need NASA images. Amy explains how the agency gets its cool shots.
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.
A huge arc of plasma has been imaged rising from the sun's surface by a NASA solar observatory, producing a beautiful view of the sun's magnetic dynamics in action. Continue reading →
For the first time, a massive solar flare revealed the process that created it, confirming new theories about flares and the explosive ejections of solar material often linked with them.
The first few months of 2014 have certainly been active for our nearest star and last night the sun unleashed another X-class flare -- the most powerful type of solar flare. Continue reading →
On Saturday, the sun erupted with an X-class flare, knocking out radio communications for several minutes. Continue reading →
