The top panels of this image show the Hubble Ultra Deep Field (HUDF) taken with WFC3/IR in three filters. This is the deepest image of the sky ever taken. By deconvoling the image with the Hubble PSF, and reconvolving it with the (sharper) JWST PSF, we can view the HUDF with JWST. For this "simulation", a noise suppression algorithm was used. The resulting JWST image, which is much sharper than the HUDF, gives a hint of what deep field images will look like on JWST.
