Webb Observations of Hubble Ultra Deep Field (Full Field)

This image of the Hubble Ultra Deep Field was taken by the James Webb’s Near-Infrared Camera. The Webb image observes the field at depths comparable to Hubble – revealing galaxies of similar faintness – in just one-tenth as much observing time. Hubble’s original image, made between 2003 and 2004, took 11 days to capture the view of nearly of 10,000 galaxies. By comparison, in 2022, Webb was able to observe the same target in high-resolution, in less than 24hrs. Webb’s new data complements previous data sets by providing detailed information for just about all of the galaxies in this field, allowing scientists to piece together the bigger picture.
