Alpha Centauri is the second studio album by German electronic music group Tangerine Dream.

The other difference is that this album focuses on dark, spacey soundscapes as opposed to jam sessions.

[citation needed] The shift in instrumentation resulted in an atmosphere dubbed by Edgar Froese himself as "Kosmische Musik".

Side 1 employs the same guitar riff as "Fly and Collision of Comas Sola", but the single was at the time otherwise an unconnected release.

Re-releases of Alpha Centauri in the 2000s have however included either or both parts of Ultima Thule as bonus tracks.
