  Karl Guthe Jansky - Wikipedia, the free encyclopedia
Jansky was born in Norman, Oklahoma, and studied at the University of Wisconsin where he received his Bachelor of Science degree in Physics in 1927.
Jansky was assigned the job of investigating the sources of static that might interfere with radio voice transmissions.
Two men who learned of Jansky's discovery in 1933 were of great influence on the later development of the new study of radio astronomy: one was Grote Reber, who singlehandedly built a radio telescope in his back yard in 1937 and did the first systematic survey of radio waves from the sky.

 Jansky - Wikipedia, the free encyclopedia
In radio astronomy, the flux unit or jansky (symbol Jy) is a non-SI unit of electromagnetic flux equivalent to 10
The unit "jansky" is named after the pioneering radio astronomer Karl Jansky.
The brightest natural radio sources have flux densities of the order of one (to one hundred) jansky, which makes the jansky a suitable unit for radio astronomy.

Jansky was born in 1905 in Norman, OK, where his father was Dean of Engineering at the University.
Jansky was named for Karl Guthe, a German-American physicist and teacher whom his father admired.
Jansky's first assignment was to investigate natural sources of radio static, and he undertook construction of a short-wave recording system in addition to doing measurements of static interference with long-wave reception.

 Jansky and Reber: Two Remarkable Stories in Early Radio Astronomy   (Site not responding. Last check: 2007-11-03)
Extraterrestrial radio waves were first detected in 1931-32 by Karl Jansky at the Bell Telephone Labs in New Jersey while he was investigating sources of interference to recently opened, trans-Atlantic shortwave (20 MHz) radiotelephone circuits.
At this time Jansky was only a few years beyond his physics degree from the University of Wisconsin, where his father was a professor of engineering.
Jansky studied this "star noise" off and on until 1935, establishing that the emission came from the direction of the Milky Way and the galactic center, but did not pursue it in any further detail.

While trying to determine the causes of radio communications static, Jansky discovered (1931) radio waves from extraterrestrial sources—a discovery that prompted the investigations of Gröte Reber and led to the development of the science of radio astronomy.

The jansky (Jy), is sometimes called the flux unit, is the unit used mostly in radio astronomy to measure the strength, or more precisely the flux density, of radio signals from space.
In measuring signal strength, it's necessary to take into account both the area of the receiving antenna and the width of the frequency band in which the signal occurs.
It is named after Karl Jansky, the American physicist who discovered radio waves from space in 1930.
