Ultraviolet Night Airglow of Venus
Barth, C. A.; Stewart, A. I.
The night airglow spectrum of Venus in the ultraviolet is dominated by the v' = 0 progressions of the gamma and delta bands of nitric oxide. The bands are produced by two-body radiative recombination of nitrogen and oxygen atoms. Since the source of these atoms is in the dayside thermosphere, the night airglow is a tracer of the day-to-night therm…
International Ultraviolet Explorer probes the universe.
Hartline, B. K.
The impact of the International Ultraviolet Explorer (IUE), launched in January 1978, on ultraviolet astronomy is reviewed. An assortment of firsts has been achieved, including the first UV observation of a supernova, the first high-resolution UV spectrum of a star in another galaxy, and the first evidence that acetylene is present in the upper at…
