This image from the NASA/ESA Hubble Space Telescope shows a dwarf galaxy named UGC 685. Such galaxies are small and contain just a tiny fraction of the number of stars in a galaxy like the Milky Way. Dwarf galaxies often show a hazy structure, an ill-defined shape, and an appearance somewhat akin to a swarm or cloud of stars—and UGC 685 is no exception to this. Classified as an SAm galaxy—a type of unbarred spiral galaxy—it is located about 15 million light-years from Earth.
