SOFIA: Stars and the Space Between

By sending an infrared telescope to altitudes of 12,000 meters (40,000 feet) and higher, NASA and the German Aerospace Center (DLR) conduct astronomical research that would be impossible using telescopes based on Earth. The Stratospheric Observatory for Infrared Astronomy—SOFIA—is the only airborne telescope in the world. Infrared imaging of stars and planets is difficult from ground-based observatories, because water vapor in Earth's lower atmosphere blocks most infrared radiation. SOFIA operates from a modified Boeing 747, soaring high above occluding vapor to capture infrared emissions from distant galaxies. Using instruments that include a high-speed imager and a sensitive far-infrared spectrometer, SOFIA will provide insights into distant star formation, the chemical composition of deep space, and the atmospheres of planets within our own solar system.
