This infrared view of the Large Magellanic Cloud, a satellite galaxy to our own Milky Way, offers astronomers a unique chance to study the life cycle of stars and dust in a single galaxy.
Blue represents starlight from older stars. Red around bright regions is dust heated by stars, while the red dots scattered throughout are either dusty, old stars or more distant galaxies. The greenish clouds contain cooler interstellar gas and molecule-sized dust grains.
