Karl Guthe Jansky was born on October 22, 1905, in what was then the Oklahoma Territory. His father, Cyril M. Jansky, was the dean of the University of Oklahoma College of Engineering. From a young age, Jansky showed a keen interest in science and technology, inspired by his father's work in the field.
Jansky pursued his passion for physics and radio engineering at college, where he excelled in his studies. After completing his education, he landed a job at Bell Labs, a prestigious research facility known for its cutting-edge innovations in telecommunications.
It was at Bell Labs that Jansky made his groundbreaking discovery in August 1931. While working on minimizing static interference in voice radio transmissions, he detected radio waves emanating from the Milky Way. Further investigation revealed that these waves originated from an unexpected source - the constellation Sagittarius. This discovery marked the birth of radio astronomy and solidified Jansky's place in history as one of its founding fathers.
Jansky's work revolutionized our understanding of the universe and paved the way for future advancements in radio astronomy. His research on the origins of static interference, including its link to thunderstorms, laid the foundation for further exploration into the cosmic sources of radio waves.
James Van Allen, another prominent astronomer, also made significant contributions to the field of space research. His discovery of the radiation belts encircling the earth, which were later named after him, complemented Jansky's work and expanded our knowledge of the cosmos.
