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.
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.
NASA's Nuclear Spectroscopic Telescope Array has turned its gaze from distant black holes and focused on our sun, producing the most sensitive measurement of high-energy solar X-rays ever achieved.
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 →
On July 26, NASA's Solar Dynamics Observatory (SDO) noticed something peculiar about its normally uninterrupted view of the sun -- a chunk was missing. Continue reading →
And barely an hour apart from each other, too! Continue reading →
NASA's Interface Region Imaging Spectrograph watched a magnetic eruption in the solar corona, giving us the most intimate view of the creation of a CME yet. Continue reading →
