The red supergiant underwent five stages in the life cycle of a star. The yellowish regions represent visible images taken with the Hubble Space Telescope, over which are the blue ultraviolet images taken with GALEX. Since GALEX doesn't have Hubble's spatial resolution, the blue blobs show up as blurry and larger than reality. Credit: Kevin Schawinski (Oxford), NASA/GALEX/HST, COSMOS.
