Two very different galaxies drift through space together in this image taken by NASA's Hubble Space Telescope. The peculiar galaxy pair is called Arp 116. Arp 116 is composed of a giant elliptical galaxy known as Messier 60 (or M60) and a much smaller spiral galaxy, NGC 4647. The faint bluish spiral galaxy NGC 4647 is about two-thirds of M60 in size and much lower in mass - roughly the size of our galaxy, the Milky Way. Read more
