THE TRIFID NEB­ULA

Sky at Night Magazine - - EARTH FROM SPACE -

This is a spec­tac­u­lar and brightly coloured three-in-one neb­ula. Your im­ages will show red ‘emis­sion’ re­gions of glow­ing hy­dro­gen gas, blue ar­eas where light is be­ing re­flected and scat­tered from nearby stars, and dark ar­eas of dense dust ob­scur­ing what lies be­hind.
