Henize 206 is a region of star formation in the Large Magellanic Cloud of the approximate scale of the Orion belt and sword. Our Spitzer Space Telescope infrared images and Cerro Tololo Inter-American Observatory (CTIO) optical images show that the region is experiencing very energetic star formation. ... A few percent of the total flux from this brightest region in Henize 206 emanates from infrared peaks of subparsec scale. ...
