NGC 1309 is a spiral galaxy 100 million light-years away. It is about a third of the size of our Milky Way Galaxy, but no disappointment to view. The bluish spirals are caused by small stars and lanes of dust particles. The galaxy lies near Eridanus, which is one of the constellations we studied this week. This is a stunning photograph from the Hubble Space Telescope which also shows many other galaxies which are more distant in the background.
