Number 249 (Story #2), November 21, 1995 by Phillip F. Schewe and Ben Stein THE INFRARED SPACE OBSERVATORY (ISO) , just put into orbit by the European Space Agency, will extend the work performed a decade ago by NASA's IRAS satellite, but with greater sensitivity and with a 10-fold improvement in spatial resolution. ISO will look at infrared light in the 3-200 micron wavelength range. This corresponds to targets at temperatures between 10 and 1000 K, objects such as cool stars, brown dwarfs, the interstellar medium, and distant infrared galaxies. ISO's eccentric orbit keeps the craft out of Earth's radiation belts for 16 hours each day. (New Scientist, 4 November 1995.)
