Encyclopedia > Grote Reber

Grote Reber (December 22, 1911December 20, 2002) was one of the pioneers of radio astronomy. He was instrumental in repeating Karl Jansky's pioneering but somewhat simple work, and conducted the first sky survey in the radio frequencies.

Karl Guthe Jansky (October 22, 1905 – February 14, 1950), was the American physicist and radio engineer who in 1932 discovered that the Milky Way galaxy emanates radio waves; he did not follow up his discovery, but it marked the birth of radio astronomy. ... There are several uses of the word survey: // Kinds of surveys Statistical surveys are used in marketing and polling research. ...


Reber was born and raised in Wheaton, Illinois, a suburb of Chicago, and graduated from Armour Institute of Technology (later Illinois Institute of Technology) in 1933 with a degree in radio engineering. He was a ham radio operator, and worked for various radio manufacturers in Chicago from 1933 to 1947. When he learned of Jansky's work in 1933, he decided this was the field he wanted to work in, and applied to Bell Labs where Jansky was now working. However this was during the height of the Great Depression and there were no jobs available.

Instead Reber decided to build his own radio telescope in his back yard in Wheaton, a suburb of Chicago. His design was considerably more advanced than Jansky's, consisting of a parabolic sheet metal mirror 9 meters in diameter, focusing to a radio receiver 8 meters above the mirror. The entire assembly was mounted on a tilting stand allowing it to be pointed in various directions, although not turned. The telescope was completed in 1937.

Reber's first receiver operated at 3300 MHz and failed to detect signals from outer space, as did his second, operating at 900 MHz. Finally his third attempt at 160 MHz was successful in 1938, confirming Jansky's discovery. Reber turned his attention to making a radio-frequency sky map, which he completed in 1941 and extended in 1943. He published a considerable body of work during this era, and was the initiator of the "explosion" of radio astronomy in the immediate post-WWII era.

During this time he uncovered a mystery that was not explained until the 1950s. The standard theory of radio emissions from space was that they were due to black-body radiation, light (of which radio is a non-visible form) that is given off by all hot bodies. Using this theory one would expect that there would be considerably more high-energy light than low-energy due to the presence of stars and other hot bodies. However Reber demonstrated that the reverse was true, and that there was a considerable amount of low-energy radio signal. It was not until the 1950s that synchrotron radiation was offered as an explanation for these measurements. As the temperature decreases, the peak of the black body radiation curve moves to lower intensities and longer wavelengths. ... Hannes Alfvén, and Nicolai Herlofson, predicted synchrotron radiation in space in 1950 [1] Synchrotron radiation is electromagnetic radiation, similar to cyclotron radiation, but generated by the acceleration of ultrarelativistic (i. ...


Reber later donated his telescope to the NRAO in Green Bank, West Virginia, and helped supervise its re-construction at that site. The telescope was then mounted on a turntable, allowing it to be pointed in any direction. Reber also helped with a reconstruction of Jansky's original telescope as well. In all Reber spent four years working for the National Bureau of Standards. The National Radio Astronomy Observatory (NRAO) is an institution set up by the United States government for the purpose of radio astronomy. ... Green Bank is located within Pocahontas County, West Virginia (Eastern Region), inside the Allegheny Mountain Range, and can be reached via Hwy 28. ... As a non-regulatory agency of the United States Department of Commerce’s Technology Administration, the National Institute of Standards (NIST) develops and promotes measurement, standards, and technology to enhance productivity, facilitate trade, and improve the quality of life. ...


In the 1950s he wanted to return to active studies but much of the field was already filled with very large and expensive instruments. Instead he turned to a field that was being largely ignored, that of very low-frequency radio signals. However most low-frequency signals are filtered out by the Earth's atmosphere, so Reber moved to Tasmania to start his observations there. Layers of Atmosphere (NOAA) Earths atmosphere is a layer of gases surrounding the planet Earth and retained by the Earths gravity. ...
