The Hubble Ultra Deep Field in 3D

Fascinating video about an experiment they did with the Hubble telescope. They pointed the telescope in to a dark, empty part of space about the size of a small grain 0f sand and then left the lens open for 10+ days. This video shows and talks about what they found.  In that incredibly small window they found tens of thousands of galaxies each of which contains hundreds of billions of stars. It really gives a glimpse of a perspective of how big and infinite the universe is.
