HST ACS F814W image of the gravitational lens RXJ1131−1231. The lensed AGN images of the spiral source galaxy are marked by A, B, C, and D, and the star forming regions of the spiral galaxy form the spectacular lensed structures. The primary lens galaxy and the satellite lens galaxy are indicated by G and S, respectively.
