Caption: Allan Sandage. Portrait of the US astronomer Allan Rex Sandage (born 1926). In 1960, Sandage discovered the optical object that was later identified with the first of the strong radio sources that would be called quasars. Much of his career has involved the study of stellar evolution and the ages of globular star clusters, as well as calculating the Hubble Constant (or the rate of expansion of the universe). Both of these subjects allow the age of the universe to be estimated. Photographed in 1954. ***** NO ADVERTISING USAGE IN CONSUMER OR TRADE MAGAZINES WITHOUT PRIOR WRITTEN APPROVAL *****.
