Star Factory Messier 17

Nebula's are star-forming regions rich in interstellar clouds of dust, hydrogen, helium and other ionized gases. How else do they keep the star factory running? On Tuesday, NASA released this breathtaking image of "star factory Messier 17," also known as the Omega Nebula or the Swan Nebula.

From NASA:

Sculpted by stellar winds and radiation, the star factory known as Messier 17 lies some 5,500 light-years away in the nebula-rich constellation Sagittarius. At that distance, this degree wide field of view spans almost 100 light-years. The sharp, composite, color image utilizing data from space and ground based telescopes follows faint details of the region's gas and dust clouds against a backdrop of central Milky Way stars. Stellar winds and energetic light from hot, massive stars formed from M17's stock of cosmic gas and dust have slowly carved away at the remaining interstellar material producing the cavernous appearance and undulating shapes.
