description Overview

W49A

W49A is a giant H II region and one of the most massive star-forming complexes in the Milky Way, located approximately 36,000 light-years away in the constellation Aquila. It contains numerous massive O-type stars and is studied as an analog to distant starburst regions because of its extreme luminosity at infrared and radio wavelengths. The nebula is obscured by dust at visible wavelengths, so it...

W51 Nebula
