Grand Spiral Galaxy  - M 100

Known as a grand design spiral galaxy, M100 is a large galaxy of over 100 billion stars with spiral arms that are like our own Milky Way Galaxy. This Hubble Space Telescope image of M100 was made in 2009 and reveals bright blue star clusters and intricate winding dust lanes which are hallmarks of this class of galaxies. Studies of variable stars in M100 have played an important role in determining the size and age of the Universe.
