This is the largest ever released by NASA's Hubble telescope. So large in fact that it would take 600 HD TV's to properly display this image.
Nonetheless, the amount of data or pixels of this image is infinitesimally small compared to our Universe. Thoughts of the Total Perspective Vortex burst into my mind upon watching this magnificently beautiful and large photo turned into a thought provoking video.
Any Hitchhiker's Guide to the Galaxy fan will be able to tell you about the TPV. However, if you are unfamiliar with it, Nick Page does a great job animating this scene in the book below.
