At the center of this picture is an unremarkable looking faint star, too faint to be seen through all but the largest amateur telescopes. This ancient star, in the constellation Leo, is called SDSS J102915+172927 and has been found to have the lowest amount of elements heavier than helium of all stars yet studied. It has a mass smaller than that of the Sun and is probably more than 13 billion years old. ESO/Digitized Sky Survey 2
