Question 9: A. so B. whereas C. or...e was an American who graduated with a 
degree in engineering. He went on to work as an amateur radio operator and later decided to try to build his 
own radio telescope in his backyard. Reber's first two radio receivers failed to pick up any signals from outer 
space, but in 1938, his third radio telescope successfully picked up radio waves from space. 
A radio telescope consists of a large parabolic-shaped dish antenna or a combination of two or more. The 
significance of the parabolic shape allows for the incoming radio waves to be concentrated on one focal point, 
allowing the signals to be picked up as strongly as possible. A larger dish means that more signals can be 
received and focalized. 
In the late 1950s and early 1960s, the largest radio telescope of the time was invented with a seventy-six-
meter telescope although larger telescopes have been made since then. The largest current radio telescope in 
the world is the RATAN-600 in Russia, whose diameter is 576 meters. It has provided valuable feedback of the 
sun's radio wavelengths and atmosphere. The largest radio telescope in Europe is a 100-meter diameter 
telescope in Germany, and the largest radio telescope in the United States is the Big Ear in the state of Ohio. 
The largest array of telescopes is the Giant Metrewave Radio Telescope in India. 
Radio telescopes have provided scientists with valuable information about our universe. One of the most 
important functions of radio telescopes is their ability to allow scientists to track different space probes, the 
unmanned space missions in outer space. Radio telescopes allow for the travel of space probes into places like 
the surface of Mars that are too dangerous for men to explore. Without radio wave technology, scientists would 
not know much of what inhabits the universe nor would they be able to see it. Radio waves are our eyes and 
ears in outer space.
