M45 is also known as the Pleiades or Seven Sisters. Unfortunately in this close up image the full seven are not visible. This is one of the closest star clusters to us, and is clearly visible to the naked eye as a 'cloudy patch' in the night sky. The cluster is dominated by hot blue stars which are lighting up the dust cloud they are passing through.
