NASA’s Solar Dynamics Observatory (SDO), launched on February 11, 2010, has returned with its first images of the Sun and the images are incredible! Never before have we seen photos or videos of the sun this close or this clear (the SDO can capture images 10x higher than HD cameras).
Of course, with all NASA images you can view these shown here and many others from the SDO project at the NASA homepage or the SDO website.
this video also contains some of the new images: http://www.newsy.com/videos/nasa-releases-hi-def-images-of-sun
