Fact Sheet
Colorful Turbulence
Clouds of hydrogen gas mix with small amounts of oxygen, sulfur, and other elements in this Hubble Space Telescope image of a region of M17, a nebula that is giving birth to new stars. The nebula is about 5,500 light-years away. The energy of hot, young stars in the nebula causes the gas to glow. The different colors represent different elements.
