A Flight through the Universe
This animated flight through the universe was made by Miguel Aragon of Johns Hopkins University with Mark Subbarao of the Adler Planetarium and Alex Szalay of Johns Hopkins. There are close to 400,000 galaxies in the animation, with images of the actual galaxies in these positions (or in some cases their near cousins in type) derived from the Sloan Digital Sky Survey (SDSS) Data Release 7. Vast as this slice of the universe seems, its most distant reach is to redshift 0.1, corresponding to roughly 1.3 billion light years from Earth. The Baryon Oscillation Spectroscopic Survey (BOSS) spectroscopic data in Data Release 9 includes well over half a million galaxies at redshifts up to 0.8 – roughly 7 billion light years distant – and over a hundred thousand quasars to redshift 3.0 and beyond.

Fascinating video.

Has there been any research on what’s within the vast distances between galaxies?

I suppose we can’t really know, since we’re barely able to get a probe out of the solar system and even at that, the distances are almost unimaginable.
