A starry seahorse with a large curling tail lowers its head for a collision in this image of IC 4687 from the NASA/ESA Hubble Space Telescope.
This galaxian dragonfly, wings folded, rests deep in space. NASA’s Hubble Space Telescope clearly shows a pair of merging, edge-on galaxies called NGC 6670. Astronomers believe the two galaxies have already had one close encounter with each other and are making a second pass. The galaxies are just 50,000 light years apart. For comparison, our Milky Way Galaxy is 100,000 light-years wide and the nearest large galaxy to it is the Andromeda Galaxy at two million light-years away.
