Here is a YouTube video showing how the Hubble space telescope was used to take photos of the most distant galaxies.
In 2004, looking in the direction of one of the most dark areas of the sky, but not blocked by interstellar gas, they pointed the telescope very steadily, at a point in the constellation of Orion, for several days in order to detect the most distant galaxies.
The colour of stars or galaxies indicates their distance. The ones with the most red shift being the furthest away. Using this information the scientists were able to construct a 3D view of some 10000 galaxies and the video above illustrates the view that your would see if your were to travel that way - at warp speed perhaps. This is the first 3D picture of such distant galaxies that I have seen. Enjoy !
