2015 was an exciting year for NASA's flying observatory, the Stratospheric Observatory for Infrared Astronomy, or SOFIA. By flying at altitudes of more than 40,000 feet, above more than 99% of the water vapor in Earth's atmosphere, SOFIA can make observations with its 2.5-meter diameter infrared telescope and crew of pilots and scientists that no other current ground or space observatory can.
