the star-forming region known as Messier 17 - or more commonly the Omega or Swan Nebula - which lies in the Sagittarius constellation. It is a vast region of gas, dust and hot young stars in the heart of the Milky Way.
HubbleSite - NGC 2074 Hubble peered into a small portion of the nebula near the star cluster NGC 2074 in this 18th anniversary image. The region is a firestorm of raw stellar creation, perhaps triggered by a nearby supernova explosion. The image reveals dramatic ridges and valleys of dust, serpent-head "pillars of creation," and gaseous filaments glowing fiercely under ultraviolet radiation. The region is on the edge of a dark molecular cloud that is an incubator for the birth of new stars.
