M20 - The Trifid Nebula

Copyright: Jim and Janet Castano/Adam Block/NOAO/AURA/NSF

The constellations of Sagittarius and Scorpius are popular targets for astronomers during the summer months, even in mid-northern latitudes where they never rise very high above the horizon. The reason is the wealth of amazing objects on view, of which the Trifid Nebula is just one. It is a planetary nebula which shines at magnitude 5, putting it well within the reach of binoculars, even from light polluted skies.
It is seen visually as a white gaseous object, whilst long-exposure photography brings out its true colours as shown above. The Trifid Nebula is around 2200 ly away.
