You can now 3D-print your own miniature version of NASA's flying telescope, the Stratospheric Observatory for Infrared Astronomy (SOFIA).

Engineers at NASA's Ames Research Center in California have created an eight-piece model of the airborne observatory, and the digital files needed to 3D-print your own tiny SOFIA are free to download here

Unlike space-based observatories like the Hubble Space Telescope, which launch on top of a rocket before being deployed into orbit, the SOFIA telescope is built into an airplane. Specifically, SOFIA resides inside a modified Boeing 747 wide-body jetliner. SOFIA observes the universe from the stratosphere, where it flies at altitudes of up to 45,000 feet (14 kilometers).

"SOFIA flies higher than commercial jetliners to get above 99 percent of the water vapor in Earth's atmosphere, which blocks infrared light from reaching the ground," NASA officials said in a description of the 3D-printing files. "This is why SOFIA is capable of making observations that are impossible for even the largest and highest ground-based telescopes."

Researchers with NASA and the German space agency, which is known by its German acronym, DLR, have used SOFIA to study stars, planets, comets, black holes and more. The telescope has found atomic oxygen on Mars, watched the dwarf planet Pluto pass in front of a distant star to learn about its atmosphere, and became the first airborne observatory to study distant exoplanets

This 3D-printable version of SOFIA is built to a scale of 1/200 and is just under a foot long. It includes a miniaturized version of SOFIA's 106-inch (2.7 meters) reflecting telescope, which is situated at the rear of the aircraft behind a door that can be either open or closed. The fuselage can also be opened to reveal details of the inside of the aircraft.
