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.
