Unveiling the Brilliant Mind Behind Radio Astronomy: The Story of Grote Reber
Introduction
Grote Reber was a self-taught American radio astronomer, and his work was critical to the development of modern radio astronomy. He was one of the first to use radio waves to study celestial objects, and his pioneering work helped to expand our understanding of the universe. Reber’s story is one of passion, perseverance, and dedication, as he worked tirelessly over many years to develop new technologies and techniques for observing the cosmos. In this post, we’ll take a closer look at the life and legacy of Grote Reber.
The Early Years
Grote Reber was born in Wheaton, Illinois, in 1911. As a child, he was fascinated by science and technology, and he spent hours tinkering with radios and other electronic devices. After high school, he enrolled in the Armour Institute of Technology (now the Illinois Institute of Technology) in Chicago, where he studied electrical engineering.
Discovering Radio Astronomy
During the 1930s, Reber read about the work of Karl Jansky, who had discovered the first radio waves coming from outer space in 1932. Inspired by Jansky’s work, Reber decided to build his own radio telescope to study the cosmos.
The First Radio Telescope
In 1937, Reber constructed the world’s first parabolic radio telescope in his backyard in Wheaton. The telescope had a diameter of 31 feet and was made of sheet metal and a wire mesh. Reber used this telescope to map the radio emissions of the Milky Way, producing the first radio map of the galaxy.
The War Years
During World War II, Reber worked for the U.S. government, helping to develop radar technology. He continued to work on radio astronomy in his spare time, building a new radio telescope in Tasmania in 1949.
The Legacy of Grote Reber
Throughout his career, Reber made many important contributions to radio astronomy. He developed new techniques for observing the cosmos, including the use of small radio telescopes to study individual stars and the use of interferometry to improve the resolution of radio images. He also discovered a number of new sources of radio emission, including the first known radio galaxy, Cygnus A.
