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 .
An astronomical radio source is an object in outer space that emits strong radio waves. Radio emission comes from a wide variety of sources. Radio emission comes from a wide variety of sources. Such objects are among the most extreme and energetic physical processes in the universe .
Taeduk Radio Astronomy Observatory (TRAO) Daejeon, Republic of Korea 86–115 GHz TRAO was established in October 1986 with the 13.7 meter Radio Telescope. It opened the new era of the millimeter-wave radio astronomy in Korea as one of the main facilities of Korea Astronomy and Space science Institute [24] (KASI). It is operated by Radio ...

Astrophysical masers. Some late-type stars can produce astrophysical masers from their atmospheres and beam out coherent bursts of microwaves.. The Sun. The Sun, the nearest star to Earth, is known to emit radio waves, though it is virtually the only regular star that has been detected in the radio spectrum, because it is so close.
A radio telescope is a specialized antenna and radio receiver used to detect radio waves from astronomical radio sources in the sky. [ 1 ] [ 2 ] [ 3 ] Radio telescopes are the main observing instrument used in radio astronomy , which studies the radio frequency portion of the electromagnetic spectrum , just as optical telescopes are used to ...
