Sandage began working at the Mount Palomar observatory. In 1958 he published the first good estimate for the Hubble parameter, namely 75 km/s/Mpc, which is quite close to today's accepted value. Later he became the chief advocate of an even lower value, around 50, corresponding to a Hubble time of around 20,000 million years. Palomar Observatory is a privately-owned observatory located in San Diego County, California, 90 miles (145 km) southeast of Mount Wilson Observatory, on Palomar Mountain. ... Hubbles law is the statement in astronomy that the redshift in light coming from distant galaxies is proportional to their distance. ...


He performed spectral studies of globular clusters, and deduced that they had an age of at least 25,000 million years. This led him to speculate that the universe did not merely expand, but actually expanded and contracted with a period of 80 billion years. The current cosmological estimates of the age of the universe, in contrast, are typically of the order of 13 billion years.

Nothing is certain as to the extent of either the age or size of the universe, but the age of the Universe, according to the Big Bang theory, is defined as the largest possible value of proper time integrated along a timelike curve from the Earth at the present epoch...


He is most noted for the discovery in the M-82 galaxy of jets erupting from the core.

Dr. Sandage was born of Jewish background, but at age 60 became a Christian. He responded to the question, "Can a person be a scientist and a Christian?", with "Yes. As I said before, the world is too complicated in all its parts and interconnections to be due to chance alone."
