APOD 4.1


In this image of the Milky Way taken in the Canary Islands off of Spain, nine high resolution images of the night time sky have been combined to create a visually stunning panorama.  The Milky way galaxy is composed of over 400 billion stars and dust, which are mostly concentrated in the area of the flattened, rotating disk that holds our Solar System.  The Milky Way galaxy is classified according to Hubble's system as a Sbc because the spiral arms mostly dominate the object.  Alongside the Milky Way, the image of the waxing gibbous Moon and the Pleiades star cluster (located in between the constellation Taurus and Perseus).
