Far-infrared M17
Date
High-resolution far-infrared spectra of the nebula Messier 17 (M17) obtained with the GREAT spectrometer and SOFIA on the night of April 5-6, 2011, superimposed on a Spitzer near-infrared image. The white spectra are C II (singly-ionized carbon) and the green spectra are CO (carbon monoxide). The two panels at bottom show maps of C II and CO emission intensity within the red box in the upper panel.
