The Significant Invention

Introduction:
There are many fascinating things about the universe and there are lots to learn from it too. Most of the discoveries in outer space were in our solar system and most of them were observed from the human eye aided by telescopes. Is it possible to observe objects from outer space using instruments other than the telescope? Fortunately, we are able to explore other parts of the electromagnetic spectrum using different kinds of observations such as the radio telescope, invented by Mr. Grote Reber, who was inspired by Mr. Karl Jansky. The radio telescope has been significant in finding quasars and pulsars that are very distant from our solar system.
The Interesting Discovery:
In the 1930s, Mr. Jansky was assigned to investigate the sources of static that possibly may interfere with radio voice transmissions for his company Bell Labs. His investigation involved an antenna, designed to receive radio waves with a frequency of 20.5 MHz, which he built himself. He installed thi...
