SOFIA is a modified Boeing 747SP aircraft. Credits: NASA/Jim Ross SOFIA, t he Stratospheric Observatory for Infrared Astronomy, is a Boeing 747SP aircraft modified to carry a 2.7-meter (106-inch) reflecting telescope (with an effective diameter of 2.5 meters or 100 inches). Flying into the stratosphere at 38,000-45,000 feet puts SOFIA above 99 percent of Earth’s infrared-blocking atmosphere, allowing astronomers to study the solar system and beyond in ways that are not possible with ground-based telescope s. SOFIA is made possible through a partnership between NASA and the German Space Agency at DLR. The observatory’s mobility allows researchers to observe from almost anywhere in the world, and enables studies of transient events that often take place over oceans where there are no telescopes.
