NGC 5713 and NGC 5719
Adam Block says: " NGC 5719 and NGC 5713 make for an interesting pair of spiral galaxies. NGC 5719 is edge-on from our perspective and displays the tell-tale signs of the interaction by its warped disk. Indeed there is a very faint stream of stars that extends several galactic radii from the galaxy in both directions- a feature not typically captured. The face-on NGC 5713, peculiar as well, shows its perturbations by its complex inner structure and unusual single spiral arm. These galaxies are roughly 80 million light years away."
