   Apr 17, 2024 · It is a modified Boeing 747SP aircraft that carries a 2.5-meter telescope, making it the largest airborne observatory in the world. SOFIA is designed to study the universe in the infrared spectrum, allowing astronomers to observe celestial objects that are not visible in the visible light spectrum.

8. People also ask

   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 does Sofia stand for?

   • The Flying Observatory SOFIA, the Stratospheric Observatory for Infrared Astronomy, was 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).

   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.

   How does Sofia work?

   • Flying into the stratosphere at 38,000-45,000 feet put 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 was made possible through a partnership between NASA and the German Space Agency at DLR.

   What did Sofia discover?

   • Among SOFIA's most hailed accomplishments is the discovery of water on sun-exposed parts of the moon. This couldn't have been done by any  ground-based telescope, as the signature of water would be completely blocked out by water vapor in Earth's atmosphere.

   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.
