Hubble-James Webb comparison.jpg

Caption

A grey-scale image of the galaxy EGS_31125 at 10.6 billion years ago, visually classified as strongly barred (outlined in the centre image in a thick solid purple line with the spiral arms shown as faint purple lines). From left to right: Hubble Space Telescope WFC3 F160W and James Webb Space Telescope NIRCam F356W and F444W. This filter comparison demonstrates the effects of Point Spread Function (PSF), sensitivity and wavelength range on a galaxy image, particularly in the context of bars.
