...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...
...eleven-year sunspot cycle was ushered in last autumn when Mount Wilson observers spotted two faint spots too far from the solar equator to be survivors of the old cycle, too small to have any effect on earth. Last week near the sun's eastern edge erupted a whirling blot 16,000 miles across. Astronomers predicted magnetic storms and poor radio reception during the twelve days before the sun's rotation wheeled it out of sight, thought it might grow big enough to be seen with the unaided eye through smoked glass...
...Shapley has advanced the idea that the sun, moon, and other planets all came to life at once from an eddy swirling in the gas that was the parent of the "Milky Way." According to that thesis, the whole solar system is made up of fragments of the gas-like matter ejected from that huge shining mass of material which later was condensed into those countless stars we view as our "Milky Way." This, for Dr. Shapley, is just one of a series of similar galaxies in space and is of no particular importance...
Life does not exist on Mars or any other solar planet except Earth, in the opinion of Dr. Walter Sydney Adams, director of Mt. Wilson Observatory. Mars, most propitious of Earth's neighbors, is not only inhospitably cold and scantily watered, but also almost devoid of oxygen. Some months ago Dr. Adams and Dr. Theodore Dunham Jr. trained spectroscopes on the red planet, computed that it has under 1% as much free oxygen as Earth...
...Earth belongs) was given by Drs. J. S. Plaskett and J. A. Pearce of the Dominion Astrophysical Observatory at Victoria, B. C. Their total was 170 billion stars. The Milky Way is apparently rotating round a centre once every 220,000,000 years. From this centre they find the solar system 30,000 light years away...
