This Hubble image shows LEDA 12535, a barred spiral galaxy some 320 million light-years away in the constellation of Perseus. The color composite was assembled from images taken by Hubble’s Wide Field Camera 3 (WFC3) in ultraviolet, visible, and near-infrared light. It is based on data obtained through three filters. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / I. Chilingarian.

$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.
