NASA’s STEREO Stunning Images

STEREO. ‘STEREO (Solar TErrestrial RElations Observatory) is the third mission in NASA’s Solar Terrestrial Probes program (STP). This two-year mission will employ two nearly identical space-based observatories – one ahead of Earth in its orbit, the other trailing behind – to provide the first-ever stereoscopic measurements to study the Sun and the nature of its coronal mass ejections, or CMEs. With this new pair of viewpoints, scientist will be able to see the structure and evolution of solar storms as they blast from the Sun and move out through space.’

NASA STEREO Stunning Looping Arcs
Stunning Looping Arcs — June 9-10, 2007. This STEREO image and video clip of the Sun in extreme ultraviolet light (June 9-10, 2007) showcases a string of active regions near the Sun’s equator over about 36 hours. We see several active regions (brighter areas with the loops above them) that were lined up as they approached the edge of the Sun. Credits: NASA, STEREO.
