Sneak a peek at the deepest and sharpest infrared image of the early universe ever taken — all in a day’s work for the Webb telescope. (Literally! Webb was able to capture this image in less than one day, while similar deep field images from Hubble can take multiple weeks).

This image isn’t the farthest back we’ve ever observed. Non-infrared missions like COBE and WMAP saw the universe much closer to the Big Bang (about 380,000 years after), when there was only microwave background radiation, but no stars or galaxies yet. Webb sees a few hundred million years after the Big Bang.
