Today's Astronomy Picture of the Day shows NGC 6872, a "barred spiral". It is described as "a conventional barred spiral in which severe tidal interaction took place" (you think?).
I thought that perhaps NGC 6872 might have been a galaxy listed by Halton Arp in his famous Atlas of Peculiar Galaxies, but it does not appear to be there.
What it most puts me in mind are some of the "stargate sequence" images from the film 2001: A Space Odyssey, created with drops of ink and resembling exploding stars, globular clusters and galaxies.
