Sofia: Sky Telescope
It could be said that the sky comes alive at night. From Earth's surface, the brief absence of the Sun brings a spectacle of lights - stars, galaxies, nebulae and planets - a window into the Universe. The Stratospheric Observatory for Infrared Astronomy (SOFIA) will take one of the largest and most versatile airborne telescopes 45,000 feet above Earth's surface to study space. Explorers have looked through this window for hundreds of years - and now through ever more powerful telescopes that work at the edge of space.
