The beautiful Trifid Nebula, also known as Messier 20, lies about 5,000 light-years away, a colorful cosmic sky. It shares this field with open star cluster Messier 21 (top left).
The Trifid nebula is about 40 light-years across and a mere 300,000 years old. That makes it one of the youngest star forming regions in our sky. M20 and M21 are easy to find with even a small telescope in the nebula rich constellation Sagittarius. In fact, this well-composed scene is a composite from two different telescopes.
