How the universe called us for the first time

It is remarkable that, even though Jansky was the first to observe and study radio waves in Astronomy, plenty of physicists before him were concerned with their presence theoretically. In the decade 1860, James Clerk Maxwell proved with his work in electromagnetism that electromagnetic waves could be linked with any wavelength, and laid the foundation for the understanding of the dissemination of electromagnetic waves, including radio waves. However, the detection and study of radio waves in the Radio astronomy frame started long after Maxwell’s work. Johannes Wilsing and Julius Schneiner tried to detect the sun’s radio waves, without success. After Jansky’s discovery in 1935, a great number of discoveries were made, with him being the pathfinder until his early death in 1950, but also other physicists like Grote Reber, who repeated his observations, the British military scientist James Stanley Hey and George Clark Southworth, Jansky’s colleague at Bell labs, with the last two detecting the sun’s radio waves. Lastly, great work was carried out by Jocelyn Bell, who was the first one to detect radio waves coming from pulsars.
