M94 |  Many detailed features in this spiral galaxy in the constellation Canes Venatici have been brought out by drastically compressed image mapping: an extremely bright inner region surrounded by a blue ring of young star clusters, a fainter yellowish region of older stars also surrounded by traces of young stars, and even further out, a very much fainter outer ring.
