Newly discovered gravitational lens system RXS J1131-1231

Image of the newly discovered gravitational lens system RXS J1131-1231 recorded by the EFOSC2 instrument on the ESO 3.6-m telescope (left panel). Deconvolution ("image sharpening", right panel) allows a better view of the four star-like components (the four images of the same distant quasar), the Einstein ring (the elongated image of the quasar's host galaxy) and the lensing galaxy (the central bright diffuse image).
