An image of the grand design spiral galaxy Messier 100 obtained with the Hubble Space Telescope resolves individual stars within the majestic spiral arms. Messier 100 (100th object in the Messier catalog of non-stellar objects) is a face-on spiral galaxy. It is a rotating system of gas and stars, similar to our own galaxy, the Milky Way. M100 is a member of the huge Virgo cluster of an estimated 2500 galaxies. The galaxy can be seen by amateur astronomers as a faint, pinwheel-shaped object in the spring constellation Coma Berenices.
