Westerlund 2, a young star cluster with an estimated age of about one or two million years, is the subject of study in this Chandra X-ray Observatory image. Until recently little was known about this cluster because it is heavily obscured by dust and gas. However, using infrared and X-ray observations, Westerlund 2 has become regarded as one of the most interesting star clusters in the Milky Way galaxy. It contains some of the hottest, brightest and most massive stars known.Image Credit: NASA/CXC/Univ. de Liège/Y. Naze et al
