Hubble Ultra Deep Field 3-D Fly-Through

This is a pretty incredible simulation and it's the best thing I've seen all day.

A flight through the Hubble Ultra Deep Field, the most distant visible-light view of the universe. The redshifts of 5,333 galaxies were converted to distances to assemble a 3-D model of the data. This scientific visualization flies through the data to showcase its true 3-D nature.
