False-color near-infrared image of the core of the young massive cluster RCW 38 taken with the adaptive-optics camera NACO on ESO’s Very Large Telescope. RCW 38 lies at a distance of about 5,500 light years from the Sun. The field of view of the central image is approximately 1 arc minute, or 1.5 light-years across.
