Joe Taylor first obtained his amateur radio license as a teenager, which led him to the field of radio astronomy. Taylor is well known in the field of amateur radio weak signal communication and has been assigned the call sign K1JT by the FCC. He had previously held the callsigns K2ITP, WA1LXQ, W1HFV, and VK2BJX (the latter in Australia). [3]
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 ...

Govind Swarup (March 23, 1929 – September 7, 2020) was a pioneer in radio astronomy.In addition to research contributions in multiple areas of astronomy and astrophysics, he was a driving force behind the building of "ingenious, innovative and powerful observational facilities for front-line research in radio astronomy".
In the case of M87, because the angle between the jet and the line of sight is not small, its nucleus is not classified as a blazar, but rather as radio galaxy. A blazar is an active galactic nucleus (AGN) with a relativistic jet (a jet composed of ionized matter traveling at nearly the speed of light ) directed very nearly towards an observer.
Astrophysics is a science that employs the methods and principles of physics and chemistry in the study of astronomical objects and phenomena. [1] [2] As one of the founders of the discipline, James Keeler, said, astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space—what they are, rather than where they are", [3] which is studied ...
Spektr-R [6] (part of RadioAstron program) (Russian: Спектр-Р) was a Russian scientific satellite with a 10 m (33 ft) radio telescope on board. It was launched on 18 July 2011 [7] on a Zenit-3F launcher from Baikonur Cosmodrome, and was designed to perform research on the structure and dynamics of radio sources within and beyond the Milky Way.
