   Jun 8, 2023 · The Stratospheric Observatory for Infrared Astronomy (SOFIA) made the first-ever measurement of heavy atomic oxygen in Earth’s upper atmosphere. Heavy oxygen is so called because it has 10 neutrons, rather than the normal eight of “main” oxygen, the form we breathe.

   Why did Sofia need an infrared observatory?

   • As an infrared observatory, SOFIA needed to be able to view the sky unobstructed by Earth's atmosphere, which absorbs most of the infrared radiation coming from space.

   What is a SOFIA telescope?

   • SOFIA soars over the snow-covered Sierra Nevada mountains with its telescope door open during a test flight. SOFIA is a modified Boeing 747SP aircraft. The observatory’s mobility allowed researchers to observe from almost anywhere in the world, and enabled studies of transient events that often take place over oceans, where there are no telescopes.

   What happened to the SOFIA observatory?

   • The observatory, fitted with an 8.9-foot-wide (2.7 meters) telescope with a nearly 20-ton mirror, used a door in the side of the aircraft to peer at the sky. A collaboration between NASA and the German Aerospace Center (known by its German acronym DLR), the SOFIA project was prematurely ended in 2022 after operating for 12 years.
