Abstract :
Cosmic static is defined as electromagnetic radiation which may be detected by radio receiving equipment and which has extraterrestrial origin. A highly directive system for detecting and recording these radiations is described and analyzed. Data are given on the variations in intensity of cosmic static in relation to various regions of the galaxy. The effects of interference are discussed. It is suggested that cosmic static is the eguivalent of thermal agitation in which all space is the conductor and the input terminals of the detecting equipment are projected by means of an antenna system to same far-distant part of space.
