...specific function of the coronagraph is to determine the wavelength distribution of the corona's ultraviolet rays in order to derive temperatures within the corona...
John L. Kohl, research associate at the Harvard Observatory and principal scientist for the program, conceived the "ultraviolet-light coronagraph." Edmond M. Reeves, lecturer on Astronomy, is directing...
...coronograph is designed to create an artificial solar eclipse, thereby permitting observation of the ultraviolet rays of the corona, the portion of the sun's atmosphere which extends well beyond the visible disk...
Presuming Voyager 2 overcomes its troubles, the twin flight is a unique project. The Voyagers go elaborately equipped for sightseeing. They carry wide-and narrow-angle television cameras, cosmic ray detectors, magnetometers, infra-red spectrometers and radiometers, as well as instruments for detecting and recording ultraviolet radiation and radio emissions from the planets. They will, it is hoped, give man his closest look yet at Jupiter, a planet that contains more matter than all the other planets in the solar system put together. The pair will also devote a good deal of attention to four of Jupiter...
...another 15% of the ozone layer. Most disastrous would be a large-scale nuclear war, which would blast enough nitrogen oxides into the atmosphere to reduce the ozone layer by as much as 70% for a period of from five to ten years. Even a slight increase in ultraviolet rays seems to cause a higher incidence of skin cancer, and a significant depletion of the ozone layer could cause far-reaching damage to plant and animal life and trigger drastic climatic changes...
