NASA. LARGE FORMAT. A superbly photogenic group of interacting galaxies is captured here by the HUBBLE space telescope. The largest of the spiral galaxies has a disk that is distorted into a rose shape by the gravitational tidal force of the companion galaxy below. The large outer arm appears partially ring-shaped, a feature observed when interacting galaxies pass through each other. The inner set of spiral arms is strongly distorted out of plane, with one arm passing behind the bulge and emerging on the other side. This group of galaxies is located in the Andromeda constellation, around 300 million light-years from Earth. 2011. Vintage chromogenic print. Numbering on front. Legend on back label. 40.6 x 40.6CM with margins.
