DescriptionThe bright star Alpha Centauri and its surroundings.jpg
English: This wide-field view of the sky around the bright star Alpha Centauri was created from photographic images forming part of the Digitized Sky Survey 2. The star appears so big just because of the scattering of light by the telescope's optics as well as in the photographic emulsion. Alpha Centauri is the closest star system to the Solar System.
Deutsch: Diese Großfeldansicht der Himmelsregion um den hellen Stern Alpha Centauri wurde aus Aufnahmen des Digtized Sky Survey 2 erstellt. Aufgrund der Lichtstreuung in der Emulsion der verwendeten Fotoplatten erscheint der Stern sehr groß. Alpha Centauri ist von unserem Sonnensystem aus gesehen das nächste Sternsystem.
