Bright waves of new stars, lanes of dark dust, and a central clump of billions of older stars highlight this Hubble Space Telescope view of Messier 100, one of the leading members of the Virgo Cluster, a collection of hundreds of galaxies. M100 is bigger and more massive than our home galaxy, the Milky Way. It is about 56 million light-years away. [ESA/NASA/STScI]
