The Northern Trifid Nebula
The Northern Trifid Nebula is smaller and more distant than its namesake M20. It lies 2,100 light-years away in the constellation Perseus. It spans about three light-years and contains both reddish and blue components. The blue is reflection nebula, where dust behind the stars reflects starlight. The red in this case is not from the usual emission of hydrogen, but rather it is the light of a massive young star that emits strongly in Hydrogen-alpha wavelengths, and whose light is being dimmed and reddened by dust within the core of the nebula. To either side of the nebula additional dust and soot is evident in large areas that contain few stars. (10-inch Astro Systeme Austria astrograph at f/6.8, SBIG STL-11000M CCD camera, Hydrogen-alpha/LRGB image with exposures of 440, 350, 180, 160, and 160 minutes, respectively)
