I am enlightened to see such a view. Thanks ESA, NASA, SECCHI, STEREO departments. Nice perspective of our solar system and neighbouring bodies, including a labeled earth and moon, as seen by STEREO satellite A on February 18, 2007.

Another neat STEREO image is the earth impacting CME taken with STEREO A HI-1A & 2A (Shown near the very end of this video)

Labeled planets and other bodies within and outside our solar system.

January 2007 - non-periodic Comet McNaught @perihelion and JPL orbit simulation

Corona Australis also known as Corona Austrina, Coronae Austrinae, and "The Southern Crown"....
contrasts with semi-circular, arc shaped Corona Borealis, "The Northern Crown." The Brightest star in Corona Australis is Alpha Coronae Australis, belonging to approximate spectral type A2V. It has an apparent magnitude of +4.10.

In the northern sky.. the brighest star in constellation Corona Borealis is a binary star system named Alpha Coronae Borealis. It has an apparent magnitude that slightly varies from +2.21 to +2.32. Interesting quote: "As the brightest star in Corona Borealis, it lent its name to the brightest in Corona Australis." - wikipedia

Our star is typed as spectral class G2V, based on temperature, size and luminosity.

Credits to STEREO, SECCHI, NASA, Ulysses, Cassini, IBEX.. and others! Many thanks for the educational tools, video, effort and science put into the Heliospheric research missions.

Please feel free to let me know if you have any further comments or thoughts about something I should add to the video annotations. I really should have added much more for Andromeda! I will gradually add a few annotations to compensate.
