APOD 3.4

Grand design is right. M100, a spiral galaxy is made up of over 100 billion stars. The defined spiral arms are similar to the one's we can find right here at home in the Milky Way Galaxy. M100 stands out as one of the brightest members of the larger Virgo Cluster of galaxies. M100 or NGC 4321 is 56 million light-years away, located near the constellation Berenice's Hair, or Coma Berenices. This particular image was captured by the Hubble Space Telescope in 2009. The bright blue star clusters and intricate winding dust lanes are the hallmark of the grand design galaxy class. This particular galaxy has been critical in helping astronomers determine the size and age of the Universe.
