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 above this vapor to capture infrared emissions from distant galaxies.
