About this image

Deep Fields within the Hubble Legacy Field

This image shows the sizes and locations within the Hubble Legacy Field of the two areas that Hubble first studied in this region, the Great Observatories Origins Deep Survey (GOODS) and the Hubble Ultra Deep Field (HUDF), along with the deepest image ever taken by Hubble, the eXtreme Deep Field (XDF).

The Hubble Legacy Field is one of the widest views ever taken of the universe with Hubble. Astronomers assembled the image from 16 years' worth of Hubble observations. The Hubble Legacy Field image combines many Hubble field surveys, including the iconic original HUDF and the first wide-field GOODS, as well as the XDF.

The image's wavelength range stretches from ultraviolet to near-infrared light, capturing all the features of galaxy assembly over time. The wide view contains about 30 times as many galaxies as in the HUDF. The new portrait, a mosaic of 7,500 exposures, covers almost the width of the full Moon.
