Apollo Imagery
A color enhancement of a far-ultraviolet photo of the Earth
high res (2.7 M) low res (174 K)
S72-36972 (21 April 1972) --- A color enhancement of a far-ultraviolet photo of Earth taken by astronaut John W. Young, commander, with the ultraviolet camera on April 21, 1972. The original black and white photo was printed on Agfacontour film three times, each exposure recording only one light level. The three light levels were then colored blue (dimmest), green (next brightest), and red (brightest). The three auroral belts, the sunlit atmosphere and the background stars (one very close to Earth, on left) can be studied quantitatively fro brightness. The UV camera was designed and built at the Naval Research Laboratory, Washington, D.C. EDITOR'S NOTE: The photographic number of the original black & white UV camera photograph from which this enhancement was made is AS16-123-19657.
