SOFIA Infrared Imagery of Comet ISON

November 26, 2013
Images of Comet ISON were obtained by SOFIA's FORCAST camera at wavelengths of 11.1, 19.7, and 31.5 microns. Measurements at 31.5 microns, crucial for determining the temperature and other characteristics of the comet's material, cannot be made using ground-based telescopes.
