Double Quasar Gravitaional lensing warped space-time! QSO 0957+561A and B On this occasion I was not after the galaxy NGC 3079 in Ursa Major, which looks lovely in this image but trying to find something called a double quasar! An intervention of a concentration of mass between Earth and the quasar is causing double imaging! Now I have seen the effects of gravitational lensing and a consequence of warped space-time At first I thought the nice double stars in the vicinity were what I was looking for. Bernd of the A-team at Slooh introduced me to Aladin Sly Atlas and I was able to locate the actual quasar.
