Editor's Notes
- Shar7e history kae The early history of radio astronomy begins in 1894, with Sir Oliver Lodge. Lodge attempted detection of radiation from the sun at centimeter wavelengths. Unfortunately over the next forty years, further attempts also failed due to inadequate detection techniques. The more recent history of radio astronomy begins in 1931 when an American engineer named Karl Jansky, while working for Bell Telephone Laboratories, conducted experiments on radio wavelength interference. Jansky detected three separate groups of static; local thunderstorms, distant thunderstorms and a steady hisstype static of unknown origin. The unknown source that Jansky found is the center of the Milky Way as he was able to show by determining its position on the sky. Jansky was the first to detect radio emission from the Galaxy. The image above shows Jansky standing with his antenna (Photo courtesy of Bell Laboratories). This rotatable antenna looks similar to a merry-go-round; the rotation allowed it to move along with the static. The work done by Jansky included receiving frequencies in the range of 15 to 30 MHz (approximately 15-m wavelengths). Jansky published three reports on his findings, which were largely ignored for many years to come. The field of radio astronomy would eventually recognize him with a unit named for him; the Jansky is equivalent to 10^(-26) watts per m^2 per Hz.
