The Early Release Observations and associated materials were developed, executed, and compiled by the ERO production team: It is part of Webb Early Release Observations. This image was created with Webb data from proposal 2736. Redshift of cluster is z=0.39 (about 4.24 billion light-years) NIRCam was built by a team at the University of Arizona and Lockheed Martin’s Advanced Technology Center.įor a full array of Webb’s first images and spectra, including downloadable files, please visit: ![]() In addition to Goddard, several NASA centers contributed to the project, including the agency’s Johnson Space Center in Houston, Jet Propulsion Laboratory (JPL) in Southern California, Marshall Space Flight Center in Huntsville, Alabama, Ames Research Center in California’s Silicon Valley, and others. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages Webb for the agency and oversees work on the mission performed by the Space Telescope Science Institute, Northrop Grumman, and other mission partners. NASA Headquarters oversees the mission for the agency’s Science Mission Directorate. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency). Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. The James Webb Space Telescope is the world's premier space science observatory. The full suite will be released Tuesday, July 12, beginning at 10:30 a.m. This image is among the telescope’s first-full color images. Researchers will soon begin to learn more about the galaxies’ masses, ages, histories, and compositions, as Webb seeks the earliest galaxies in the universe. Webb’s NIRCam has brought those distant galaxies into sharp focus – they have tiny, faint structures that have never been seen before, including star clusters and diffuse features. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying much more distant galaxies behind it. The image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago. This deep field, taken by Webb’s Near-Infrared Camera (NIRCam), is a composite made from images at different wavelengths, totaling 12.5 hours – achieving depths at infrared wavelengths beyond the Hubble Space Telescope’s deepest fields, which took weeks. This slice of the vast universe is approximately the size of a grain of sand held at arm’s length by someone on the ground. ![]() Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail. NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. These are images of background galaxies that have been stretched and distorted by the foreground galaxy cluster. They follow invisible concentric circles that curve around the center of the image. There are also many thin, long, orange arcs. In the center of the image, between 4 o’clock and 6 o’clock in the bright star’s spikes, are several bright, white galaxies. It has eight blue, long diffraction spikes. Some look as large as the galaxies that appear next to them.Ī very bright star is slightly off center. Most appear blue with diffraction spikes, forming eight-pointed star shapes. In front of the galaxies are several foreground stars. Most appear as fuzzy ovals, but a few have distinctive spiral arms. ![]() Some are shades of orange, others are white. Thousands of small galaxies appear across the image. They include foreground stars, galaxies in a galaxy cluster, and distorted background galaxies behind the galaxy cluster. This image shows many overlapping objects at various distances.
