The Last Master of Naked-Eye Astronomy

Tycho Brahe mapped the heavens with unmatched precision using only his eyes. He remains the greatest astronomer to have charted the stars before the invention of the telescope.

Before telescopes existed, Tycho built massive instruments to measure planetary positions with startling accuracy. His detailed data provided the vital foundation for Kepler to unlock the laws of planetary motion. Interestingly, his life was as colorful as his work, as he was also a famous alchemist and astrologer. He proved that you do not always need complex technology to change the course of human history.
