The first gravitationally lensed object ever discovered, Q 0957+561 is a quasar whose image is split into two by the gravity of a foreground galaxy. In this image, the two star like objects are the split images of the quasar. The fuzzy object near top quasar image is the foreground galaxy. The quasar lies at a redshift of 1.41. The foreground galaxy lies at a redshift of 0.39. In optical light, Q0957+561 appears as two point images of roughly 17 mag separated by 6.1 arcseconds. | ||
