OBSERVATORY WILL FEATURE RADIO ON POPULAR PROGRAM

The College Observatory staff will introduce a notable innovation into its general public educational program tomorrow evening, with the first of a series of 15-minute radio talks on various astronomical subjects. Twenty-two of these talks, by nine members of the Observatory staff, are planned for Tuesday and Thursday evenings during the next three months, to be broadcast from Station WEEI, the Edison Electric Illuminating Company, of Boston.

Many Subjects to be Discussed

Among the subjects to be discussed are the origin of the Earth and its age, "The Stuff that Stars are Made Of," "Life in Other Worlds," "Comets, Eclipses, the Use of Telescopes," and "Beyond the Milky Way".

The Harvard Observatory, one of the oldest in America, is also one of the most famous astronomical institutions in the world. Its photographic collection is by far the largest in the world, and is used in the problems of stellar evolution; the history of the stars, and the dimensions and structure of the sidereal universe.

The first radio talk of the series, to be given by Dr. Harlowe Shapley at 7.45 o'clock tomorrow night, will be on "What are the Stars?" Dr. Shapley is Paine Professor of Practical Astronomy at Harvard, and has been director of the College Observatory since 1921.
