NASA\u2019s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb\u2019s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.<\/p>\n\n\n\n

<\/a><\/figure><\/div>\n\n\n\nThousands of galaxies \u2013 including the faintest objects ever observed in the infrared \u2013 have appeared in Webb\u2019s view for the first time. This slice of the vast universe covers a patch of sky approximately the size of a grain of sand held at arm\u2019s length by someone on the ground.<\/p>\n\n\n\n
This deep field, taken by Webb\u2019s Near-Infrared Camera<\/a> (NIRCam), is a composite made from images at different wavelengths, totaling 12.5 hours \u2013 achieving depths at infrared wavelengths beyond the Hubble Space Telescope\u2019s deepest fields, which took weeks.<\/p>\n\n\n\n The image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago. The combined mass of this galaxy cluster acts as a gravitational lens<\/a>, magnifying much more distant galaxies behind it. Webb\u2019s NIRCam has brought those distant galaxies into sharp focus \u2013 they have tiny, faint structures that have never been seen before, including star clusters and diffuse features. Researchers will soon begin to learn more about the galaxies\u2019 masses, ages, histories, and compositions, as Webb seeks the earliest galaxies in the universe.<\/p>\n\n\n\n This image is among the telescope\u2019s first-full color images. The full suite will be released Tuesday, July 12, beginning at 10:30 a.m. EDT, during a live NASA TV<\/a> broadcast.
