Mind-Boggling New Images of the Sun

NASA's recently launched Solar Dynamics Observatory is returning early images that confirm an unprecedented new capability for scientists to better understand our sun's dynamic 
processes.

Some of the images from the spacecraft show never-before-seen detail 
of material streaming outward and away from sunspots. Others show
 extreme close-ups of activity on the sun's surface. The spacecraft 
also has made the first high-resolution measurements of solar flares 
in a broad range of extreme ultraviolet wavelengths.
