  1. "Alpha Centauri" is an album by the German electronic music group Tangerine Dream. The music on this album is quite different from Tangerine Dream’s first album Electronic Meditation, partly because of a heavier reliance on keyboards and electronic technology, although they still mostly remain in the background: the dominant instruments on the album are organ and flute. The other difference is that this album focuses on dark, spacey soundscapes as opposed to jam sessions. The shift in instrumentation resulted in an atmosphere dubbed by Edgar Froese himself as Kosmische musik.

Alpha Centauri or Toliman is the brightest star in the southern constellation of Centaurus and the third brightest star in the night sky. The Alpha Centauri system is located 1.34 parsecs or 4.37 light years from the Sun, making it the closest star system to our Solar System. Although it appears to the unaided eye as a single object, Alpha Centauri is actually a binary star system whose combined visual magnitude of −0.27 makes it the third brightest star seen from Earth after the −1.46 magnitude Sirius and the −0.72 magnitude Canopus.
