The galaxy cluster MACS-J0417.5-1154 is so massive it is warping the fabric of space-time and distorting the appearance of galaxies behind it, an effect known as gravitational lensing. This natural phenomenon magnifies distant galaxies and can also make them appear in an image multiple times, as Webb saw here. Two distant, interacting galaxies -- a face-on spiral and a dusty red galaxy seen from the side -- appear multiple times, tracing a familiar shape across the sky. Active star formation, and the face-on galaxy’s remarkably intact spiral shape, indicate that these galaxies’ interaction is just beginning. Image credit: NASA / ESA / CSA / STScI / V.

$This Webb image shows the RX J1131-1231 galaxy distorted by gravitational lensing into a dim ring; at the top of the ring are three very bright spots with diffraction spikes coming off them, right next to each other; these are copies of a single quasar in the lensed galaxy, duplicated by the gravitational lens; in the center of the ring, the elliptical galaxy doing the lensing appears as a small blue dot.
