Hubble space telescope images 200312/9/2023 ![]() The observation – among the very first science observations undertaken by Webb – is part of Early Release Science (ERS) program 1334, one of 13 ERS programs designed to help astronomers understand how to use Webb and make the most of its scientific capabilities. On June 20, 2022, the James Webb Space Telescope spent just over one hour staring at Messier 92 (M92), a globular cluster 27,000 light-years away in the Milky Way halo. Pagan (STScI).Įditor’s Note: This post highlights data from Webb science in progress, which has not yet been through the peer-review process. Download the full-resolution image of M92 from the Resource Gallery at the Space Telescope Science Institute. The image is about 5 arcminutes (39 light-years) across. The gap covers the dense center of the cluster, which is too bright to capture at the same time as the fainter, less dense outskirts of the cluster. The black strip in the center is a chip gap, the result of the separation between NIRCam’s two long-wavelength detectors. This image is composite of four exposures using four different filters: F090W (0.9 microns) is shown in blue F150W (1.5 microns) in cyan F277W (2.77 microns) in yellow and F444W (4.44 microns) in red. The near-infrared camera observations were taken from 3 September to 27 November 2003.Image of the globular cluster M92 captured by the James Webb Space Telescope’s NIRCam instrument. Astronomers incorporated the advanced camera's visible-light observations into the image to better discriminate the colours of the distant galaxies. This composite image was assembled from exposures taken by the near-infrared camera and the advanced camera. Located in the constellation Fornax, the region is so empty that only a handful of stars within the Milky Way galaxy can be seen in the image. In ground-based photographs, the patch of sky in which the galaxies reside (just one-tenth the diameter of the full Moon) is largely empty. Peering into the Ultra Deep Field is like looking through a 2.5 metre-long soda straw. The Ultra Deep Field observations represent a narrow, deep view of the cosmos. If discovered, these record-breaking galaxies may offer clues to the emergence of galaxies when the universe was only 2 to 5 percent of its present age. The remotest galaxies will only appear in the infrared image. To find them, astronomers must combine the infrared and visible-light images. Some light also has been absorbed by intergalactic hydrogen.Īstronomers are hoping to strike it rich by finding some of the farthest known galaxies, existing perhaps 400 million years after the big bang. The light from remote galaxies has been stretched from visible to invisible infrared wavelengths by the expansion of space. Astronomers used Hubble's near-infrared camera to find very distant galaxies that cannot be seen in visible light. This infrared image offers a slightly farther look into the universe's past, compared with the snapshot of the same field taken in visible light by Hubble's Advanced Camera for Surveys. This galaxy-studded view represents a "deep" core sample of the universe, cutting across billions of light-years. Taken by the Near Infrared Camera and Multi-Object Spectrometer aboard the NASA/ ESA Hubble Space Telescope, the image is part of the Hubble Ultra Deep Field survey, the deepest portrait ever taken of the universe. This infrared view reveals galaxies far, far away that existed long, long ago.
