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 ...
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.
Smethurst began creating science communication videos when she was a postdoctoral fellow at the University of Nottingham for the Sixty Symbols YouTube channel, run by Brady Haran and the university's physics department. [4] She also has appeared on Deep Sky Videos, another channel operated by Haran on the theme of astronomy. [14]
John Gatenby Bolton FAA FRS CBE [1] (5 June 1922 – 6 July 1993) was a British-Australian astronomer who was fundamental to the development of radio astronomy.In particular, Bolton was integral in establishing that discrete radio sources were either galaxies or the remnants of supernovae, rather than stars.

The observations with the Collaroy antenna not only marked the beginning of radio astronomy in Australia, but also the first time radio astronomy had provided important information on a problem in traditional optical astronomy. [5] The introduction of interferometry was probably Pawsey's most important contribution to radio astronomy. [4]
Explorer 49 (also called Radio Astronomy Explorer-2, RAE-B) was a NASA 328 kg (723 lb) satellite launched on 10 June 1973, for long wave radio astronomy research. It had four 230 m (750 ft) X-shaped antenna elements, which made it one of the largest spacecraft ever built.
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.
