Organized from far-ultraviolet to near-ultraviolet bright galaxies, this poster encapsulates the heart of the Galaxy Evolution Explorer (Galex) mission to study how galaxies and star formation rates have changed over the past 10 billion years. To create this image, Galex scientists organized 196 different nearby galaxies in bins of increasing ultraviolet color. By placing the various snapshots side by side, astronomers can see how galaxies age differently. When viewed in ultraviolet, active star-forming regions in galaxies can be seen as glittering blue structures, while a soft, golden glow indicates the presence of older stars.
