Solomon J. Buchsbaum, Executive Director of the Bell Labs Communications Sciences Division (left) and David Cohen, Mayor of Holmdel, NJ examine historic marker honoring the beginning of the science of radio astronomy. The marker was placed in front of Bell Labs Holmdel building on Crawford Cornor Road. More than 40 years ago, the late Karl Jansky, then a research engineer at Bell Labs, was studying the causes of static which was interfering with the Bell System's trans-Atlantic radio-telephone service. When he discovered that part of the static were radio waves emanating from the center of our own galaxy, the Milky Way, a new field of science -- radio astronomy -- was born. In the background is the horn antenna built by Bell Labs in 1960 for Project Echo, a passive satellite communications experiment. It was later modified for the Telstar experiments. Bell Labs uses the antenna today to study improved radio communications techniques.
