SMA Reveals Giant Star Cluster in the Making

This image from the Smithsonian's Submillimeter Array maps the projected density of molecular gas in the central 30 light years of W49A. Brighter colors mark denser regions. The brightest region at the image center is less than three light-years across, yet it contains about 50,000 suns' worth of molecular gas.
