Forthcoming from Dr. Charlotte Emma Moore, 35-year-old Princeton Observatory researcher already known for her spectroscopic measurement of sunspot temperatures, the identification followed a triangular cooperation. Dr. Moore took some especially clear laboratory spectra of phosphorus provided by Dr. Carl Clarence Keiss of the Bureau of Standards, compared them minutely with some very faint lines lately observed on the infra-red solar spectrum by Mount Wilson's Harold Delos Babcock, found that three lines coincided...
...observers will use 14 spectrographs and ten direct cameras to record the appearance of the meteors. In order to photograph their spectra, special red plates will be used...
...addition to getting the spectra of the meteors, the watchers hope to find the velocity of the train drifts in the upper atmosphere, 60 miles above the earth. At this height there is a terrific speed and nothing else gives as good an idea of the velocity as the paths of the meteors...
...Harvard Observatory and Dr. Joseph C. Boyce of the Massachusetts Institute of Technology have at last succeeded in identifying the element responsible for the major part of the sun's coronal radiation, marking the first important step in unravelling a mystery dating from the first observations of the spectra of the corona more than sixty years...
...mass before it spread out into the gaseous brilliantly shaded tail, which may have been between 50 and 100 miles long." One million meteors enter the earth's atmosphere each hour, become incandescent from friction. But rarely are astronomers able to photograph the hot spots and analyze the spectra. Last week Harvard's Dr. Peter Mackenzie Millman proudly reported that he had spectral pictures of nine meteors. Six, possibly seven were mostly stone. All contained some iron (heated to vapors of between 2,600° and 4,600° F.). One or more contained calcium, manganese, aluminum, chromium...
