M20 is a beautiful object in the constellation Sagittarius. It consists of three (out of four) Nebula types: Emission Nebula (the red glowing gas), Reflection Nebula (the blue glowing gas) and Dark Nebula (the dark lanes crossing in front of the previous ones). The emission nebula is fueled by several hot stars type O5 to O7. M20 is a young nebula, about 300,000 years old, and is part of the same complex of nebulosity of which the Lagoon Nebula, M8, is also part of.
