These two images are of the same part of the sky. The image on the left is from the original Hubble Ultra Deep Field observation. JWST’s Near-Infrared Camera took the image on the right. Hubble’s observation with its Wide Field Camera 3, required an exposure time of 11.3 days. The JWST image only took 0.83 days. Several areas within the Webb image reveal previously invisible, red galaxies. You can download the full resolution from the Space Telescope Science Institute.
