This video zooms into the small areas of sky that the Hubble Space Telescope was aimed at to construct the eXtreme Deep Field, or XDF. The region is located in the southern sky, far away from the glare of the Milky Way, the bright plane of our galaxy. In terms of angular size, the field is a fraction the angular diameter of the full moon, yet it contains thousands of galaxies stretching back across time. Hubble pointed at a tiny patch of southern sky in repeat visits (made over the past decade) for a total of 50 days, with a total exposure time of 2 million seconds. More than 2,000 images of the same field were taken with Hubble's two premier cameras: the Advanced Camera for Surveys and the Wide Field Camera 3, which extends Hubble's vision into near-infrared light.
