NASA. LARGE FORMAT. HUBBLE telescope. This image from the Hubble Space Telescope shows an exceptional group of interacting galaxies called "Arp." 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 band of blue jewels that crosses the top is the combined light of clusters of extremely bright and hot young blue stars. These massive stars shine intensely in ultraviolet light. The smaller, nearly edge-on companion shows distinct signs of intense star formation in its core, perhaps triggered by the encounter with the companion galaxy. A series of spiral patterns uncommon in the larger galaxy is a telltale sign of the interaction. The large outer arm appears partially as a ring, a feature observed when interacting galaxies pass through each other. This suggests that the smaller companion has in fact plunged deeply, but off-center, through UGC 1810. 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. It is not yet clear how these two spirals connect. "ARP" is in the constellation Andromeda, about 300 million light years from Earth. The image shows a tenuous tidal bridge of matter between the two galaxies, which are separated by tens of thousands of light years from each other. The interaction was photographed on December 17, 2010 by Hubble's Wide Field Camera.Vintage chromogenic print. Numbering in the margin on the front.
