Star forming region RCW 49 surrounds a young star cluster, Westerlund 2. This cluster is not able to be seen in the visible spectrum, so this image was captured in the infrared by the Spitzer Space Telescope. The black and white image is from the infrared data. The color image was taken with X-ray from the Chandra telescope, appearing in false color. Westerlund 2 is in Centaurus. This cluster contains some of our galaxy's most luminous and massive stars and is 2 million years old or less.
