Radio astronomy is a subfield of astronomy that studies celestial objects at radio frequencies. The first detection of radio waves from an astronomical object was in 1933, when Karl Jansky at Bell Telephone Laboratories reported radiation coming from the Milky Way .
Channel 37 in System M and N countries occupied a band of UHF frequencies from 608 to 614 MHz. This band is particularly important to radio astronomy because it allows observation in a region of the spectrum in between the dedicated frequency allocations near 410 MHz and 1.4 GHz. The area reserved or unused differs from nation to nation and ...
With improved equipment, Ryle observed the most distant known galaxies in the universe at that time. He was the first Professor of Radio Astronomy in the University of Cambridge and founding director of the Mullard Radio Astronomy Observatory. He was the twelfth Astronomer Royal from 1972 to 1982.

Steinberg and Denisse were the co-founders in 1953 of the Paris Observatory's radio astronomy station in Nançay. Steinberg played a major part in the construction of the large decimeter radio telescope, [ 6 ] [ 7 ] which was officially inaugurated in May 1965 by Charles de Gaulle [ 3 ] but became fully operational only in 1967.
Arthur Edwin Covington (21 September 1913 – 17 March 2001) was a Canadian physicist who made the first radio astronomy measurements in Canada. Through these he made the valuable discovery that sunspots generate large amounts of microwaves at the 10.7 cm wavelength, offering a simple all-weather method to measure and predict sunspot activity, and their associated effects on communications.
By scanning the sky with radio telescopes, Hurley and her team located another, similar radio pulse that repeated only once every 2.9 hours – the slowest ever observed so far.
Grote Reber (December 22, 1911 – December 20, 2002) was an American pioneer of radio astronomy, which combined his interests in amateur radio and amateur astronomy.He was instrumental in investigating and extending Karl Jansky's pioneering work and conducted the first sky survey in the radio frequencies.
After releasing a study describing the observation in January 2022, O’Doherty and a team of astronomers at the Curtin University node of the International Centre for Radio Astronomy Research, or ...
