The planetary nebula BD+30 3639 was imaged by SOFIA using FORCAST (Faint Object InfraRed Camera for the SOFIA Telescope; P.I. T. Herter, Cornell University) at wavelengths of 6.4, 7.7, 11.1, 11.3, and 33.6 microns. BD+30 3639 (also known as PN G064.7+05.0) is located at a distance of 1.2 kiloparsecs.
Atomic oxygen is a key component in regulation of energy and mass exchanges within the Martian atmosphere. Neutral atomic oxygen (O I) was detected in the Martian atmosphere at a frequency of 4.7 THz (63 μm) on 14 May 2014 using the high-frequency channel of the far-infrared heterodyne spectrometer GREAT (German Receiver for Astronomy at Terahertz Frequencies; P.I. Rolf Güsten, Max Planck Institut für Radioastronomie) onboard SOFIA. The [O I] line was found in absorption against the Mars continuum with a high signal-to-noise ratio (see figures).
