Solar activity as seen with STEREO's SECCHI imagers

Solar activity as seen with STEREO's SECCHI imagers from the Sun out to Earth. These images wrap around the sky so that you see Earth from both sides. Numerous Coronal Mass Ejections (CMEs) are seen erupting from the Sun and heading out to Earth orbit.

Images at center and left are from the STEREO-A observatory, while the two images on the right are from STEREO-B. Data taken Feb. 1-19, 2010.
