 Going beyond our galaxy, Hubble captured two nebulae inside the small Magellanic cloud, situated as to appear as one. Intense radiation from the brilliant central stars is heating the hydrogen in each of the nebulae, causing them to glow red. This is part of a study to understand how interstellar dust is different in galaxies that have a far lower supply of heavy elements. The small Magellanic cloud has between a fifth and a tenth of the amount of heavy elements that the Milky Way does. Because it is so close, astronomers can study its dust in great detail and learn about what dust was like earlier in the universe's history.
