...theory advanced by Dr. Shapley at the meeting deals with the distances in the universe and fixes these relative distances larger than ever before, almost beyond the conception of the human mind. The Harvard director has previously overthrown the accepted Kapteyn theory and has now elaborated on his own theory which replaced...
...universe was a geocentric one, and in the sixteenth century Copernicus made the first great step in astronomical research by overturning this old theory in favor of a heliocentric one which held that the earth and the planets went around the sun. In 1902, a man named Kapteyn put forth the theory that the sun was the center of things and that the stars were scattered about it. This Kapteyn Universe, as it was called, was in good standing till 1917 when Dr. Shapley found that we were not the center of things after...
...Cepheids from us. In this way he has calculated that the large Magellanic cloud is 86,000 light years away from us, a light year being the distance that a ray of light travels in a year at the rate of 186,000 miles per second. In the Kapteyn Universe, it was held that there was no star over 35,000 light years away...
...Bart J. Bok, of Kapteyn Astronomical Laboratory in Groningen, Holland, has joined the Observatory staff for one year to carry out researches in spectrophotometry and stellar statistics. Dr. Leon Hufnagel, of Poland, has returned to the Harvard Observatory for a few months to continue his astrophysical researches. Dr. A. Pannekoek, director of the Astronomical Institute of the University of Amsterdam, visited the Harvard Observatory for a few days in October in the interest of his researches on the structure of the Milky...
...operation with Professor Kapteyn of Holland, the Observatory is also making an exhaustive study of the magnitude and position of stars far too small to be seen by the naked eye. There are nearly 100,000,000 such stars, but by selecting typical areas it is possible to generalize accurately about the entire number...
