Negative optical photograph of Alpha Centauri
Negative optical photo of Alpha Centauri,the third brightest star in the sky. Alpha Centauri is in fact a double star; the presence of two stars (A & B) is just discernable here from the double diffraction spikes which surround the image. The pair,along with a faint companion known as Proxima Centauri,form the nearest known star system to our own,at a distance of only 4.3 light years. Alpha Centauri A & B,are about 20 arc seconds apart & orbit each other every 80 years. Proxima Centauri lies over two degrees away,out of the frame of this photograph
