Galaxy NGC 5584 from Hubble WFC3
The brilliant, blue glow of young stars traces the graceful spiral arms of galaxy NGC 5584. Thin, dark dust lanes appear to be flowing from the yellowish core, where older stars reside. The reddish dots sprinkled throughout the image are largely background galaxies.
