...three years ago 58 solar elements had thus been recognized. Then Dr. Charlotte Emma Moore, 38-year-old Princeton astronomer, was able with the help of two colleagues to announce phosphorus...
...human beings would have to carry umbrellas coated with lead before venturing under the glare of "Nova Cassiopeiae." Other highlights of the astronomers' convention: Nos- 60, 61, 62. In the sun hydrogen, helium, calcium, sodium, carbon, nitrogen, and many another terrestrial element have been identified by comparing the solar spectrum with very clear spectra of substances photographed in the laboratory...
Last week Dr. Charles Greeley Abbot, head of the Smithsonian Institution and world-famed authority on solar radiation, declared that if William Shakespeare had lived in the 20th Century he would have become an astronomer. One thing Astronomer Shakespeare would have had to get straight from the start is the different classes of nebulae. Astronomers apply nebula not only to whole galaxies of stars far beyond the Milky Way. but also to patches of dark or faintly luminous matter within the Milky Way, which is the home galaxy of earthlings. They may be distinguished by calling the local patches galactic...
Chicago's Northwestern University last week announced successful tests of a "sunburnometer," a recording device to measure the intensity of the ultraviolet component of the sun's light which causes sunburn. The sunburn-causing wave lengths can be considered as the "health band" in the solar spectrum, mainly because it contains the still narrower band which produces vitamin D in the skin. Developed by Professors Walter S. Huxford and Robert Cashman, the "sunburnometer" is noi sensitive to visible light or to the short radiation on the other side of the sunburn band. It may also be used...
...Given this manifestation of solar activity, our interest lies in the determination of any possible terrestrial influence," Andrews said. "The presence of huge magnetic fields in the sunspots results in their acting as howitzers to pour forth charged particles of matter into the interplanetary realm. If the earth is in the range of the howitzer, its atmosphere is the recipient of these particles, and, beyond doubt, electrical phenomena should occur there...
