This Hubble Space Telescope image, known as the Hubble Ultra Deep Field, reveals about 10,000 galaxies and combines ultraviolet, visible, and near-infrared light. Two programs that will use the James Webb Space Telescope will add more detail to this image, capturing thousands of additional galaxies in a fuller range of infrared light. Webb will return both imagery and data known as spectra, providing more details about some of the earliest galaxies to exist in the universe for the first time.

This image shows where the James Webb Space Telescope will observe the sky within the Hubble Ultra Deep Field, which consists of two fields. The Next Generation Deep Extragalactic Exploratory Public (NGDEEP) Survey, led by Steven L. Finkelstein, will point Webb’s Near-Infrared Imager and Slitless Spectrograph (NIRISS) on the primary Hubble Ultra Deep Field (shown in orange), and Webb’s Near-Infrared Camera (NIRCam) on the parallel field (shown in red). The program led by Michael Maseda will observe the primary field (shown in blue) using Webb’s Near-Infrared Spectrograph (NIRSpec).
