  2. Explorer 49 - Wikipedia

    en.wikipedia.org/wiki/Explorer_49

    The Radio Astronomy Explorer B (RAE-B) mission was the second of a pair of RAE satellites. It was placed into lunar orbit to provide radio astronomical measurements of the planets, the Sun, and the galaxy over the frequency range of 25-kHz to 13.1-MHz. The experiment complement consisted of two Ryle-Vonberg radiometers (nine channels each ...

  3. Radio astronomy - Wikipedia

    en.wikipedia.org/wiki/Radio_astronomy

    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 .

  4. Channel 37 - Wikipedia

    en.wikipedia.org/wiki/Channel_37

    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 ...

    en.wikipedia.org/wiki/Nançay_Radio_Observatory

    Radio astronomy emerged after the Second World War, when experts and surplus equipment became available for civilian use.The École Normale Superieure was given three 7.5 m diameter Würzburg Riese that the British had seized from the Germans during the war.

  6. Arthur Covington - Wikipedia

    en.wikipedia.org/wiki/Arthur_Covington

    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.

    The Vermilion River Radio Observatory (VRO) was a research facility operated by the University of Illinois from 1959 to 1984, featuring a 400-foot (120 m) linear parabolic radio telescope. The 420-acre (170 ha) site was a pioneering facility in radio astronomy.

    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. [1]

    en.wikipedia.org/wiki/Explorer_38

    Explorer 38 (also called as Radio Astronomy Explorer A, RAE-A and RAE-1) was the first NASA satellite to study Radio astronomy. Explorer 38 was launched as part of the Explorer program, being the first of the 2 RAE satellites. Explorer 38 was launched on 4 July 1968 from Vandenberg Air Force Base, California, with a Delta J launch vehicle. [3]
