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 .
The Star-Spectroscope of the Lick Observatory in 1898. Designed by James Keeler and constructed by John Brashear.. Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, ultraviolet, X-ray, infrared and radio waves that radiate from stars and other celestial objects.
A new type of stellar object has been discovered releasing energetic bursts of radio waves every 22 minutes. ... at the Curtin University node of the International Centre for Radio Astronomy ...

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 astronomy division in KASI. [25] Korean VLBI Network (KVN) Republic of Korea 22/43/86 ...
Very-long-baseline interferometry (VLBI) is a type of astronomical interferometry used in radio astronomy. In VLBI a signal from an astronomical radio source, such as a quasar, is collected at multiple radio telescopes on Earth or in space. The distance between the radio telescopes is then calculated using the time difference between the ...
The radio window is the region of the radio spectrum that penetrate the Earth's atmosphere. Typically, the lower limit of the radio window's range has a value of about 10 MHz (λ ≈ 30 m); the best upper limit achievable from optimal terrestrial observation sites is equal to approximately 1 THz (λ ≈ 0.3 mm).
