Bio
famous astronomer Walter Baade’s Ph.D. student in stellar evolution. During the early 1950s he served as Edwin Hubble’s observing assistant at the Mount Wilson and Palomar Observatories. Hubble, for whom the space telescope is named, discovered that the universe is larger than the Milky Way and that it is expanding.
During the course of his studies he made seminal contributions to dating the ages of stars and the expansion age of the universe, classifying galaxies, and understanding galaxy formation and evolution. He led the first major redshift—or distance—surveys of galaxies, from which he created a three-dimensional map to explore galaxy distribution and the dynamics of the nearby universe. Sandage was the first to recognize the existence of quasars without strong radio emission. Quasars are the brightest and most distant objects in the universe. He developed new techniques for observing, which affected a broad range of astronomical topics.
