This video zooms in from a wide field image of the night sky into globular cluster Messier 9, ending on Hubble's image. Hubble's detailed image of this star city resolves over 250 000 individual stars. This ball of stars is located towards the centre of our galaxy. A wide palette of colours is visible here, a testament to the varied temperatures of the stars in the cluster. Red stars are cooler, while blue ones are hotter.
