Back in 2004 NASA pointed the Hubble Space Telescope, with newly installed advanced surveying cameras, at an uninteresting dark patch of the sky – purely for curiosity. After 3 months of gathering light readings, astronomers used the results to create the Hubble Ultra Deep Field, the deepest image of the universe ever taken in visible light.
NASA has now created the above 3D fly-through simulation of that same image to give people more context to viewing the 10,000 separate galaxies in the tiny piece of sky.
