Description

Messier 17 (NGC 6618), also known as the Omega or Swan Nebula, is a bright emission nebula in the constellation Sagittarius. Located about 5,500 light-years away, it is an active star-forming region where intense radiation from young, massive stars causes the surrounding hydrogen gas to glow. Dark dust lanes sculpt its characteristic swan-like silhouette.
