Study of the Cosmos, at best, is considered a semi-scientific discipline, primarily because the laboratory for carrying out measurements and tests of theories (the Cosmos) has been largely inaccessible for centuries. The cosmic vista into the yonder, however, continued to fascinate humankind due to its inherent beauty and sheer curiosity. The inven...

... formation and evolution of stars from regions of interstellar space containing other gases, which are the sources of radio waves, have been widely studied with radio telescopes, yielding exceptionally useful information on star birth. New galaxies, such as Cygnus A, have been found to be a million times brighter than Milky Way in radio-wave region [12] [13] of emission spectrum, with large lobes of radio-wave emission (Figure 3) around the central region emitting in the optical domain-detailed studies showed that the outer radio wave lobes are only 3 million years old as compared to the central region going back to 10 billion years. Radio astronomy has revealed altogether new facts about the Cosmos, such as the existence of quasi-stellar objects (quasars) in 1960 [14]- [16], which emit brightly both in the visible and the radio frequency region of the electromagnetic wave spectrum. ...
