New picture of the month from the James Webb Space Telescope of the quasar RX J1131-1231, features an excellent example of gravitational lensing as the foreground galaxy smears the image of the background quasar into a bright arc and creates four images of the object.

Image Description: A small image of a 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 centre of the ring, the elliptical galaxy doing the lensing appears as a small blue dot. The background is black and empty.
