| Shown here is the "star factory" Messier 17. It is about 5,000 lightyears away from Earth in the constellation Sagittarius. The view here spans almost 100 lightyears. M17 has a large stock of cosmic gas which contributes to its large amount of stellar birth. M17 is also known as the Omega Nebula and the Swan Nebula. |
