Zooming in on stars in the Andromeda Galaxy’s halo (1)

This video zooms in on the location of Hubble observations in the Andromeda Galaxy’s giant stellar stream. An area which appears virtually empty in the wide-field view is revealed as being packed with many stars.

The halo is a relatively sparse sphere of stars and dark matter which surrounds a galaxy’s disc.
