![]() We asked members of the PEARLS team that created this image to share their thoughts and reactions while analyzing this field: Download the full-resolution version from the Space Telescope Science Institute. This representative-color image was created using Hubble filters F275W (purple), F435W (blue), and F606W (blue) and Webb filters F090W (cyan), F115W (green), F150W (green), F200W (green), F277W (yellow), F356W (yellow), F410M (orange), and F444W (red). Because this image is a combination of multiple exposures, some stars show additional diffraction spikes. Light from the most distant galaxies has traveled almost 13.5 billion years to reach us. Thousands of galaxies over an enormous range in distance and time are seen in exquisite detail, many for the first time. This image represents a portion of the full PEARLS field, which will be about four times larger. A swath of sky measuring 2% of the area covered by the full moon was imaged with Webb’s Near-Infrared Camera (NIRCam) in eight filters and with Hubble’s Advanced Camera for Surveys (ACS) and Wide-Field Camera 3 (WFC3) in three filters that together span the 0.25 – 5-micron wavelength range. The NIRCam observations will be combined with spectra obtained with Webb’s Near-Infrared Imager and Slitless Spectrograph (NIRISS), allowing the team to search for faint objects with spectral emission lines, which can be used to estimate their distances more accurately. This beautiful color image unveils in unprecedented detail and to exquisite depth a universe full of galaxies to the furthest reaches, many of which were previously unseen by Hubble or the largest ground-based telescopes, as well as an assortment of stars within our own Milky Way galaxy. The image is comprised of eight different colors of near-infrared light captured by Webb’s Near-Infrared Camera (NIRCam), augmented with three colors of ultraviolet and visible light from the Hubble Space Telescope. ![]() “Medium-deep” refers to the faintest objects that can be seen in this image, which are about 29 th magnitude (1 billion times fainter than what can be seen with the unaided eye), while “wide-field” refers to the total area that will be covered by the program, about one-twelfth the area of the full moon. The image, which accompanies a paper published in the Astronomical Journal, is from the Prime Extragalactic Areas for Reionization and Lensing Science (PEARLS) GTO program. The Hubble space telescope creates photographs that no human being, let alone the most creative artist could ever generate for us to enjoy.NASA’s James Webb Space Telescope has captured one of the first medium-deep wide-field images of the cosmos, featuring a region of the sky known as the North Ecliptic Pole. The light emitted from these stars traveled from another time if not another century, until it was captured by these images. What photography is incapable of delivering is a picture of space and time, but these atomized impressions of color, the stars captured in these photographs are, however, pictures of time. One could almost believe that all this is not only rationally motivated, but rather that these prominent images which the Hubble (unlike any other instrument let alone the human eye) makes are concrete pictures of the invisible. Dangerous maintenance maneuvers are executed again and again to keep the Hubble functioning. Renowned scientists place the Hubble on the same niveau as Galileo Galilei's original telescope. For one and a half decades, Hubble has helped revolutionize our understanding of the universe its gaze goes further in time and space than ever before. It has occupied the editorial columns and feature pages of the world press ever since a space shuttle's robot arm placed the fragile telescope in orbit in 1990. The Hubble space telescope is one of the finest instruments humanity has ever sent into space. The large formats of these photographs enable complete immersion into the universal world of the stars. The abstract and beguiling beauty of gentle fog, colorful swirls, and glistening light is an invitation to stroll through the Milky Way and discover unanticipated solar systems. Viewing these panoramas of outer space is like taking a spectacular trip.
