[edit] Summary

A rendering of the w:2dF Galaxy Redshift Survey data.
This was created using the Intrepix AstroVis software created as part of a university project.
The data set used is the "best spectroscopic observations" in ASCII format.
30% of the sources (galaxies) were chosen at random from the data set to be rendered for this image.
Fluctuations in density in various parts of the universe are clearly visible from this image.

Created by Enoch Lau. As a courtesy, please let me know if you alter this image or this image description page.
