Astronomers from Max Planck Institute for Astronomy, Heidelberg, Germany  and Stockholm University have identified the most massive star in our home galaxy's largest stellar nursery, the star-forming region W49. The star, named W49nr1, has a mass between 100 and 180 times the mass of the Sun. Only a few dozen of these very massive stars have been identified so far. As seen from Earth, W49 is obscured by dense clouds of dust, and the astronomers had to rely on near-infrared images from ESO's New Technology Telescope and the Large Binocular Telescope to obtain suitable data. The discovery is hoped to shed light on the formation of massive stars, and on the role they play in the biggest star clusters.
