Back Detection of OH and O<sub>2</sub> in atmosphere of Venus

Detection of OH and O2 in atmosphere of Venus


Date: 19 May 2008
Satellite: Venus Express
Depicts: VIRTIS spectrum of OH and O2 in atmosphere of Venus
Copyright: Piccioni et al.

Comparison of the observed night-side airglow spectrum (black line) with OH synthetic spectra. The most prominent emission features at 1.27 and 1.58 µm are due to O2. The other features are the OH fundamental bands at 1.44 µm (2-0) and 2.80 µm (1-0). The 250 K synthetic spectrum (green line) is shown below the observed spectrum for the full range. Full details in A&A, 483, L29-L33, May 2008.
