Super-Galaxies & Cepheids. Astronomer Harlow Shapley of Harvard, who loves to systematize the universe, was the first man to find that stellar galaxies like the Milky Way, each containing billions of stars, were sometimes huddled in groups which he calls "super-galaxies." Last week he reported the discovery, made by astronomers at Harvard's observatory in South Africa, of two new, far-off super-galaxies, each of which is about 1,000,000 light-years in diameter (one light-year equals approximately six trillion miles). Another discovery, nearer home, concerned the Cepheid variables-a class of stars, mostly yellow...
...Shapley's report to the Academy dealt principally with observations of southern galaxies and clusters, and was given in collaboration with Dr. John S. Paraskevopoulus, Superintendent of the South African station...
...Shapley said that the "newly found prenomenon" of Cepheid distribution may prove to be "an indicator of gravitational potential throughout a galaxy." However, there may be another, alternative explanation of the peculiar distribution, involving the distribution of various chemical substances in the Magellanic Cloud, Shapley said. There is a possibility that the chemical distribution of the cloud is such that the large stars were found in densely populated star areas...
