Sun Plasma FlickersCredit: Solar Dynamics ObservatoryA close-up, profile view of an active region in extreme ultraviolet light showcased several small spurts of plasma as they flickered out and retreated back into the sun over about 13 hours (June 16, 2011). This wavelength captures ionized helium at about 60,000 degrees not far above the sun's surface. Flashes of small solar flares can be seen triggering most of these spurts.

Monster ProminenceCredit: NASA/SDONASA's Solar Dynamics Observatory captured this view of a powerful M3.6 Class solar flare on Feb. 24, 2011 during a 90-minute sun storm. NASA scientists called the display a "monster prominence" that kicked up a huge plasma wave.
Class X2 Solar FlareCredit: NASA SOHOThe image of the powerful Class X2 solar flare of Feb. 14, 2011, shows how it appeared to both the Solar Dynamics Observatory in extreme ultraviolet light (center sun disk) and the SOHO's C2 coronagraph. This was the largest flare in more than four years
The First Time I Ever Saw Your FaceCredit: NASAA full-disk multiwavelength extreme ultraviolet image of the sun taken by SDO on March 30, 2010. False colors trace different gas temperatures. Reds are relatively cool (about 60,000 Kelvin, or 107,540 F); blues and greens are hotter.
Purple RainCredit: SDO/AIAThis image depicts coronal rain. Encircled are two plasma streamers, one hitting the sun's surface and another incoming behind it.
Shooting UpCredit: NASA/GSFCA prominence leaps off the surface of the sun in this new image from NASA's Solar Dynamics Observatory released on April 22, 2010. The prominence occurred on March 30.
