The Telescope-Toting 747 That Sees More than Hubble
A telescope-toting 747 is about to become astronomy's most versatile tool In the movies, opening the door on a plane at 45,000 feet is disastrous. But this spring it will be standard procedure on one 747-one carrying a telescope high enough to capture the cosmos better than ever before. Built into the tail end of a Boeing 747, the Stratospheric Observatory for Infrared Astronomy (SOFIA) will soar above the atmospheric water vapor that blocks most infrared light from ground observatories, to shoot detailed images of star-forming nebulae, planets' atmospheres and clouds of organic molecules. The 2.5-meter mobile telescope-operated by NASA and Germany's space agency-will best the Hubble and Spitzer space telescopes by scanning the widest range of light of any scope, from ultraviolet to the far infrared. And because SOFIA is easier to design and maintain than a space telescope, it could be built and operated for a third of the cost. Stargazing...
