![]() One of the Hubble Space Telescope’s most iconic images is the Hubble Ultra Deep Field, which unveiled myriad galaxies across the universe, stretching back to within a few hundred million years of the Big Bang. 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.Ĭredit: NASA, ESA, A. Expanding further, we see the Hubble data overlaid on a ground-based view using data from the Digitized Sky Survey.Īn orange outline shows the field of view of NASA’s upcoming Nancy Grace Roman Space Telescope. The view then expands to show a wider Hubble survey of that area of sky (white outline), which captured about 265,000 galaxies in a large mosaic. This zoom-out animation begins with a view of 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. Such an observation would fuel new investigations into multiple science areas, from the structure and evolution of the universe to star formation over cosmic time. ![]() As a result, a Roman Ultra Deep Field would collect millions of galaxies, including hundreds that date back to just a few hundred million years after the big bang. The Roman Space Telescope will be able to photograph an area of sky 100 times larger than Hubble with the same exquisite sharpness. Now, astronomers are looking ahead to the future, and the possibilities enabled by NASA’s upcoming Nancy Grace Roman Space Telescope. Similar observations have followed since then, including the longest and deepest exposure, the Hubble Ultra Deep Field. ![]() The resulting Deep Field image captured thousands of previously unseen, distant galaxies. In 1995, the Hubble Space Telescope stared at a blank patch of the sky for 10 straight days. Koekemoer (STScI), Acknowledgement: Digitized Sky Survey A Roman Ultra Deep Field would collect millions of galaxies, including some of the rarest and most distant 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.Ĭredit: NASA, ESA, and A. An orange outline shows the field of view of NASA’s upcoming Nancy Grace Roman Space Telescope. These Hubble images are overlaid on an even wider view using ground-based data from the Digitized Sky Survey. 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. Two insets reveal stunning details of the galaxies within the field.īeyond the Hubble Ultra Deep Field, additional observations obtained over the past two decades have filled in the surrounding space. 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. 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 composite image illustrates the possibility of a Roman Space Telescope “ultra deep field” observation.
