This image, taken with Hubble's Advanced Camera for Surveys shows a part the globular cluster NGC 6752.
Behind the bright stars of the cluster, a denser collection of faint stars is visible—a previously unknown dwarf spheroidal galaxy. This galaxy, nicknamed Bedin 1, is about 30 million light-years from Earth.
