The blue areas the Hubble Space Telescope image are young stars, the darker areas are dust lanes, while the reddish spots and splotches are galaxies in the background.[3] 250 Cepheid variables have been observed in NGC 5584. The image is a composite of several exposures taken in visible light between January and April 2010 with Hubble's Wide Field Camera 3. External links
