|
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. |
