The Sun's Innermost Atmosphere
This combined image from Nov. 8-9, 2012, shows the sun's innermost atmosphere as seen by the Solar Dynamics Observatory (SDO) inside a larger image provided by the Solar and Heliospheric Observatory (SOHO). A coronal mass ejection can be seen traveling away from the sun in the upper right corner. Scientists can compare the images to correlate what's happening close to the sun with what happens further away.
