NGC3079 & The Twin Quasar

About this image

QSO 0957+561 A/B was the first identified gravitationally lensed object in 1979. It's a single quasar appearing as two objects due to its light being bent by an intervening galaxy YGKOW G1 located directly between Earth and the quasar. This is a mosaic of two images to show quasar field of view with respect to NGC 3079. The Twin quasar lies at a redshift of z = 1.41 (8.7 billion light years).
