James Webb Deep Field Image

NASA's James Webb Space Telescope captures the deepest and sharpest infrared image of the distant universe, revealing stunning details of galaxy cluster SMACS 0723. This composite image, taken by Webb's Near-Infrared Camera (NIRCam) over 12.5 hours, showcases thousands of galaxies, including the faintest objects ever observed in infrared. The image, equivalent to a grain of sand held at arm's length, depicts SMACS 0723 as it appeared 4.6 billion years ago, with the combined mass of the galaxy cluster acting as a gravitational lens. Webb's NIRCam unveils previously unseen structures within these distant galaxies, providing insights into their masses, ages, histories, and compositions, and shedding light on the earliest galaxies in the universe.
