Description

My main focus with this image was not the galaxy NGC 3079, but the quasar "QSO 0957+561 A/B". It is a quasar around 8 billion light years distant, and is being gravitationally lensed such that it appears in two places at once from our vantage point. Version B has the "twin" quasar marked at the yellow arrow.
