M100 is one of the brightest members of the Virgo cluster of galaxies. It is located in the constellation of Coma Berenices and is a beautiful example of a nearly face-on spiral galaxy. Visually, this galaxy has two bright spiral arms and several fainter arms. Color photographs reveal the young blue stars in these spiral arms. The galaxy has a slightly asymmetric shape, which may be the result of interaction with neighboring galaxies. M100 can be located with a pair of binoculars, although the best detail can be seen with a large telescope.
