The model and movies made here were made by Dinoj Surendran and Mark Subbarao.

The software in which the model was built is Partiview, written by Stuart Levy.

Data on galaxies come from the Sloan Digital Sky Survey, prepared by Mark Subbarao of Sloan / U Chicago / Adler.

The picture of the Milky Way in some of the movies was taken by the COBE satellite.

Data for the Milky Way, locations of the local galaxies, and Partiview code for the Cosmic Microwave Background was taken from the Digital Universe models created by the American Museum of Natural History and the Hayden Planetarium. More specifically:

  1. Brian Abbott of AMNH/Hayden compiled, from M. Merrifield & J. Binney's 1998 book "Galactic Astronomy", locations of local galaxies .
  2. Brian Abbott of AMNH/Hayden and Ron Drimmel of the University of Torino prepared, mainly from HIPPARCOS satellite data, the locations of about 100 000 stars in the Milky Way

(Note that we have not used any part of the AMNH/Hayden Extragalactic Atlas, which we highly recommend for amateur and professional amateurs and professionals. It is not as pretty as ours, since galaxies are represented by colored points rather than pictures, but that also means you can run it on a slower computer. You can get it from the Digital Universe page.)

Pictures of the local galaxies were retouched from original pictures taken by the following people. The retouching consisted of clipping out a circular part of the original photograph centered at the galaxy and increasing the contrast so that the background was black. Note that most pictures come from, or were linked to by, the seds.org collection of Messier objects.
