Region of recent star formation in our Galaxy: continuum emission at 2 cm from the thermal radio source DR 21 observed at a resolution of 2 arcsec. The intesnsity is color-coded from blue (> 50 to 200 mJy/beam) to red (> 400 to a maximum of 600 mJy/beam). DR 21 is comprised of four ultracompact HII regions, each of which is excited by a recently-formed hot O or B star. The most intense HII region C (bottom) is about 10 arcsec across or 0.3 light-years (at a distance of 6000 light-years). Posted on: 04 Nov, 2003
