This composite image illustrates the possibility of a Roman Space Telescope “ultra deep field” observation. In a deep field, astronomers collect light from a patch of sky for an extended period of time to reveal the faintest and most distant objects. This view centers on the Hubble Ultra Deep Field (outlined in blue), which represents the deepest portrait of the universe ever achieved by humankind, at visible, ultraviolet and near-infrared wavelengths. Two insets reveal stunning details of the galaxies within the field.
Beyond the Hubble Ultra Deep Field, additional observations obtained over the past two decades have filled in the surrounding space. These wider Hubble observations reveal over 265,000 galaxies, but are much shallower than the Hubble Ultra Deep field in terms of the most distant galaxies observed.
These Hubble images are overlaid on an even wider view using ground-based data from the Digitized Sky Survey. An orange outline shows the field of view of NASA’s upcoming Nancy Grace Roman Space Telescope. Roman’s 18 detectors will be able to observe an area of sky at least 100 times larger than the Hubble Ultra Deep Field at one time, with the same crisp sharpness as Hubble.

Giavalsco (University of Massachusetts); , and : J. Rhodes (JPL); : K. Ratnatunga (Carnegie Mellon University); : H. Rix (MPE); : W. Sparks (STScI); , , and : S. Malhotra (Arizona State University); : R. Thompson (University of Arizona); and : S. Beckwith (STScI); : C. Kretchmer (JHU); : M. Stiavelli (STScI); : R. Bouwens (Universiteit Leiden); : R. O'Connell (University of Virginia); , and : G. Illingworth (University of California, Santa Cruz); , , and : S. Faber (University of California, Santa Cruz); : P. van Dokkum (Yale University); : A.

The 2014 Hubble Ultra Deep Field image was produced by H. Teplitz, M. Rafelski (IPAC/Caltech), A. Koekemoer (STScI), R. Windhorst (Arizona State University), and Z. Levay (STScI). The wider Hubble mosaic image was created by A. Koekemoer (STScI), including the most recent data obtained on this field, and extending an older combination by the Hubble Legacy Field team which includes G. Illingworth, D. Magee (University of California, Santa Cruz), K. Whitaker (University of Connecticut), R. Bouwens (Leiden University), P. Oesch (University of Geneva), P. van Dokkum (Yale University), I. Labbe (Swinburne University), B. Holden (University of California, Santa Cruz), M. Franx (Leiden University), and V. Gonzalez (Universidad de Chile). |
| Instrument | ACS/WFC, WFC3/IR, WFC3/UVIS |
| Exposure Dates | 2002-2019 |
| Filters | ACS/WFC (F435W, F606W, F775W, F814W, and F850LP); WFC3/IR (F105W, F125W, F140W, and F160W); WFC3/UVIS (F225W, F275W, and F336W). |
| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the ACS/WFC, WFC3/IR and WFC3/UVIS instruments on the Hubble Space Telescope. Several filters were used to sample various wavelengths. For the wider Hubble survey area, the color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter, as follows: Cyan: ACS/WFC F606W; Green: ACS/WFC F606W + F850LP; Orange: ACS/WFC F850LP. For the Hubble Ultra Deep Field image (with filters corresponding to the 2014 release), the color results from assigning different hues (colors) to each monochromatic (grayscale) image from the different filters grouped as follows: Blue: WFC3/UVIS F225W + F275W + F336W, ACS/WFC F435W + F606W; Green: ACS/WFC F775W + F814W + F850LP, WFC3/IR F105W; Red: WFC3/IR F125W + F140W + F160W. |
