Astronomers are as proud of the number of total solar eclipses they have witnessed as railroad conductors are of the gold service stripes on their sleeves. Dr. Samuel Alfred Mitchell, director of the Leander McCormick Observatory, University of Virginia, who has been looking at the skies for 32 years, has the great totality total of 15 min. (six eclipses) to his credit. He has had to travel 90,000 mi. to do it. Had he attended every instance of the sun's darkening since 1900 he would have a grand total of 68.1 min. and might have traveled...
...small reflector loaned by Harvard University. Last week, after being polished for two years, the large mirror was ready to be installed. Director Harlan True Stetson, onetime Harvard astronomer, watched the installation, summed up in his mind two problems he wants to solve with it: the causes of solar storms, which have a great effect upon terrestrial weather and radio reception; the cosmic clouds which he thinks may surround the earth and sun, may influence the intensity of solar radiation. Perkins Observatory was founded at Ohio Wesleyan University by one of its teachers of mathematics and astronomy, Hiram Mills Perkins...
...Charles Greeley Abbot, secretary of the Smithsonian Institution, members of the Institution have studied these variations in sun radiations in relation to the earth's temperature. For the last six years measurements made at Washington and other stations showed a definite temperature movement up or down whenever solar radiation increased or decreased. With a change in solar radiation of only .8%, temperature was affected as much as 5° F. This effect must be indirect, must operate through some unknown atmospheric condition since at times a rise in radiation will lower temperature and at other times will raise...
...office many of his hours have been whiled away on top of Mt. Hamilton, 30 mi. southeast of Berkeley, where, as director of Lick Observatory, he spends his time staring into the sky watching stellar orbits, comets, nebulae. For the past 30 years his fame as an authority on solar eclipses has caused him to be selected to lead expeditions into India, Russia, Spain, Australia. If you wanted to communicate with President Campbell, a letter to Lick Observatory would always reach...
...down, Venus, the evening star, appear. It was the opening performance of the country's first planetarium. A planetarium is a complex instrument for reproducing on an elaborate scale the motions of the 5,400 stars visible to man, and the planets of the solar system. It is a simple matter to note the motion of the moon and sun because they are large, travel rapidly relative to man. But the stars are so deliberate that in a planetarium the universe is speeded up as much as 4,000,000 times its normal rate to make star changes apparent...
