Hubble : Zooming on star cluster Messier 15. HD

This video sequence begins with a zoom through the constellation of Pegasus (The Winged Horse), finishing with Hubble observations of Messier 15, one of the oldest and densest globular clusters known. This glittering cluster contains over 100 000 stars, as well as something more exotic and mysterious at its core: a rare type of black hole. Credit: NASA, ESA, Digitized Sky Survey 2, Nick Risinger .
