NGC 3079 NGC 3079

NGC 3079 is a barred spiral in Ursa Major, but for me the real "star" in this image is the Twin Quasar. Which is a single quasar that appears doubled by gravitational lensing by a foreground galaxy. It took the light 8.7 billion years to arrive here. The light from one component takes an additional 14 months to arrive having taken a longer path. This was the first observable object demonstrating the effects of gravitational lensing.
