About SOFIA

SOFIA, the 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 telescopes. SOFIA is made possible through a partnership between NASA and the German Space Agency at DLR.

A long horizontal narrow orange cloud on a background of soupy brown and gray clouds. Magnetic field streamlines are laid over the orange cloud like stripes on a tiger's back.
Two images of Jupiter side by side. On the left is Jupiter with its red spot and swirling brown, beige, and white cloud bands. On the right is Jupiter in the same position but with only a few bands showing yellow and dark orange against an orange background, with no red spot visible.
This composite image of R Aquarii resembles a ring of fire over a black field, with a glowing purple “S” flowing through it. Near the center of the image, in the middle of the ring and the “S” wave, is a twinkle of bright white, which is the Mira variable in R Aquarii.
Green and red swirls of nebulae are seen over a field of bright blue stars with W3 glowing white. Two spectra are laid over the background image, one green, one red.
Cygnus-X northeast region with segments showing the magnetic field orientations and curves highlighting filaments and sub-filaments.
Arc-shaped patch with gold border and SOFIA text in gold with the telescope mirror in place of the O. The patch reads "New Zealand 2022, NASA, DLR, USRA, DSI" and shows SOFIA flying over New Zealand with the Milky Way and the fours stars of the Southern Cross constellation in the background sky.
