Fifteen years after its final flight, veterans of the Kuiper Airborne Observatory, or KAO, gathered at NASA’s Ames Research Center last Nov. 10 to witness the opening of a time capsule.

The KAO is a highly modified Lockheed C-141A cargo transport fitted with a 36-inch telescope. The observatory was based at NASA’s Ames Research Center in Moffett Field, Calif., for operations that began in 1974 and lasted 22 years before the flying observatory was retired in 1995.

CO emission observed by SOFIA/GREAT (12CO 11-10) and APEX (other lines) from supernova remnant W28.

Observations of supernova remnant W28 were made with the GREAT far-IR spectrometer during SOFIA’s Early Science program in 2011.

W28 is located in the inner part of the Milky Way Galaxy, near a large star-forming complex with HII regions including the well-known Trifid Nebula (Messier 20). W28 is about six thousand light-year from Earth and the supernova remnant is estimated to be about 20,000 years old.
