Hubble Legacy Field

The Hubble Legacy Field represents the largest, most comprehensive "history book" of galaxies in the universe. The image, a combination of nearly 7,500 separate Hubble exposures, represents 16 years of observations gathered together into a unified whole, giving the image its uneven shape. It includes Hubble deep-field surveys, such as the 2012 eXtreme Deep Field (XDF) and the 2004 Hubble Ultra Deep Field (HUDF), as well as the 2003 Great Observatories Origins Deep Survey (GOODS). The wavelength range stretches from ultraviolet to near-infrared light. The image presents a wide portrait of the distant universe and contains roughly 265,000 galaxies. They stretch back through 13.3 billion years of time to just 500 million years after the universe's birth in the Big Bang. The tiny, faint, most distant galaxies in the image are similar to the seedling villages from which today's great galaxy star-cities grew. The faintest and farthest galaxies are just one ten-billionth the brightness of what the human eye can see. The wider view contains 100 times as many galaxies as in the Hubble Ultra Deep Field. The new portrait, a mosaic of multiple snapshots, covers almost the width of the full Moon. Lying in this region is the XDF, which penetrated deeper into space than this legacy field view. However, the XDF field covers less than one-tenth of the full Moon's diameter. The Hubble Legacy Field is located in the constellation Fornax.
