...Cepheid variable stars, whose fluctuating light beams enable measurement of great interstellar distances, may prove also to hold important new clues to forces at work within the great island universes, or galaxies like our own Milky Way, Harlow Shapley, Director of the Observatory, recently told the National Academy of Sciences...

...Harvard astronomy station in South Africa reveal an unusual distribution of Cepheid variable stars in the Small Magellanic Cloud, neighbor star system of the Milky Way. There is a "peculiar concentration" of the larger, longer-period Cepheid variable stars in regions where the star population is dense, Shapley said. Cepheids fluctuate in brightness in periods ranging from a few hours to about fifty days; their mass is four to five times that...

...Harvard's famed Astronomer Harlow Shapley, during a brief excursion into entomology many years ago, discovered that the hotter an ant was, the faster it ran-in fact, that you could tell the temperature of an ant by its rate of movement...

Indications that the great stellar systems in space may possess outlying sparsely populated star "haloes" extending the system for beyond the size astronomers have generally assigned to them were reported by Dr. Harlow Shapley, Paine Professor of Practical Astronomy and Director of the Observatory speaking before a symposium of distinguished astronomers at the dedication of the McDonald Observatory's new 82-inch reflector yesterday...

Professor Shapley's talk followed and expanded an exposition by Dr. Bart J. Bok, assistant professor of Astronomy, of the attempt to disclose the Internal structure of the universe by work on the Milky Way. Bok is attempting to prove that the Milky Way is a rotating spiral nebula and has based his work on the ninety years research on external galaxies which the Observatory has conducted...
