Object  M20- The Trifid Nebula
Info

M20- The Trifid Nebula is located in the constellation  Sagittarius. It is a cloud of dust and gas where stars are forming. The red portion of this complex is light from new born stars that make the hydrogen gas glow. The blue area is caused by star light reflected from dust grains. The double star to the centre of the nebula, HN 40 (elongated in this particular image due to exposure times) illuminates the area. It is approximately 5,200 L.y. away.
