Number 19 (Story #4), January 29, 1991 by Phillip F. Schewe and Ben Stein THE MILKY WAY HAS BEEN PHOTOGRAPHED AT A WAVELENGTH of 205 microns for the first time by the Cosmic Microwave Explorer satellite. The intensity and pervasiveness of this radiation, which comes from ionized nitrogen, was unexpected. This and other microwave and far-infrared measurements made by COBE contribute to a better understanding of star formation in our galaxy. (Science News, 19 Jan.)
