A infrared, false-color composite image of the massive young stellar cluster RCW 38. The axes label the position of the image in the sky, and the insert shows a length of 3.3 light-years at the distance of the cluster (for comparison, the closest star to our sun is about 4 light-years away). CfA astronomers studying this cluster have categorized 317 young stars and their environments.
