» STEREO 10 Anniversary

STEREO currently consists of a space-based observatory, STEREO-A, orbiting the Sun just inside of 1 AU - slowly catching up with Earth as it orbits about the Sun. This viewpoint away from the Earth-Sun line allows scientists to see the structure and evolution of solar storms as they blast from the Sun and move out through space.

This movie shows a spherical map of the Sun as it currently appears, formed from a combination of the latest STEREO-A beacon images combined with a SDO/AIA. The movie starts with the view of the Sun as seen from Earth, with the 0 degree meridian line in the middle. The map then rotates through 360 degrees to show the part of the Sun not visible from Earth.
