Zooming in on the remarkable star SDSS J102915+172927

This video zoom sequence starts with a wide-field view of the bright constellation of Leo (The Lion) and slowly closes in on what looks like an unremarkable faint star. This ancient star 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.
