SDO's HMI instrument provides maps of magnetic fields of the entire surface of the sun, showing how strong they are and, for the first time ever, in which direction they are pointing.
A region of the Sun erupts in a powerful explosion, known as an "X-class" solar flare. These can cause observable effects on earth such as aurorae and power grid and communications satellite failures.
An aurora in Whitehorse Yukon Canada that appeared in the sky in the early hours of Oct. 1, 2012 due to the effects of a coronal mass ejection (CME) that erupted from the sun three days earlier.
Four separate images of the flare from the morning of July 4 show us different levels of the sun's atmosphere, allowing scientists to track how a solar eruption moves through the layers of the sun.
NASA launched five rockets to help scientists map the movement of high-altitude winds and create better models of the regions of space that can damage satellites and disrupt communications systems.
The sun blasted off a number of coronal mass ejections in just over two days in this image captured by the Solar and Heliospheric Observatory (SOHO) C2 coronograph.
This composite image, captured by NASA’s Solar Dynamics Observatory in multiple wavelengths almost simultaneously, reveals different temperatures and layers of the sun.
Spiraling magnetic loops, observed in extreme ultraviolet light by NASA's Solar Dynamics Observatory, dance and twist above an active region on the sun.
NASA's Solar Dynamics Observatory imaged the ragged shadow edge of Earth eclipsing the sun. The shadow has a variegated edge due to Earth's atmosphere.
NASA's Solar Dynamics Observatory captured this nicely rounded prominence eruption on March 19, 2011, as the disturbance erupted into space with a distinct twisting motion.
With numerous active regions populating the sun's surface, it is no surprise that March 6-8 NASA's Solar Dynamics Observatory saw flares and coronal mass ejections popping off in many directions.
After maneuvers to calibrate its instruments, the Solar Dynamics Observatory temporarily beamed back surreally distorted images of the sun reminiscent of abstract art.
