Karl G. Jansky

Karl G. Jansky was an American engineer and scientist who is considered a pioneer in radio astronomy. In the early 1930s, he discovered radio waves coming from the Milky Way galaxy while working on radio telecommunications. His work revealed that the universe emits radio signals, opening a new way for scientists to explore space beyond visible light. Jansky’s discoveries laid the foundation for modern radio astronomy, enabling us to study cosmic phenomena like stars, black holes, and galaxies in radio wavelengths, vastly expanding our understanding of the universe.
