The #Trifid #Nebula is a captivating celestial object that showcases a unique combination of cosmic phenomena.
The object is an unusual combination of an open cluster of stars, an emission nebula (the relatively dense, reddish-pink portion), a reflection nebula (the mainly NNE blue portion), and a dark nebula.

#PhotoOfTheDay: The Light, Dark, and Dusty #Trifid
#Messier20, popularly known as the Trifid Nebula, lies about 5,000 light-years away toward the nebula rich constellation Sagittarius.
It is too faint to be seen by the unaided eye. Over 75 hours of image data captured under dark night skies was used to create this stunning telescopic view.

What's happening at the center of the #Trifid Nebula?
Three prominent dust lanes that give the Trifid its name all come together. Mountains of opaque #dust appear near the bottom, while other dark filaments of dust are visible threaded throughout the nebula.
A single massive #star visible near the center causes much of the Trifid's glow. The Trifid, cataloged as M20, is only about 300 000 years old, making it among the youngest emission nebulas known.
