This is M20, the Trifid Nebula. The nebula gets its name from the dark
lanes of dust that trisect the emission portion (red portion) of the nebula.
The blue portion of the nebula is reflection nebulosity, dust and gas that
is not emitting light but simply reflecting light of the bright stars in the
region. The Trifid nebula is about 5,200 light years distant.
