Amateur archaeologists have discovered a 500-year-old compass believed to have belonged to Nicolaus Copernicus. Found in Frombork Castle, Poland, where Copernicus developed his heliocentric theory, the copper-alloy instrument was buried under the castle gardens. Experts from the Nicolaus Copernicus Museum confirm the compass's possible connection to the astronomer. Copernicus lived in the castle, where he later wrote *De Revolutionibus Orbium Coelestium* (1543), a foundational work in modern science.
