The Nebra Celestial Disk, dating back at least 3,600 years, is considered the oldest astronomical stellar map of cosmic phenomena.

This disk is, therefore, the oldest representation of the night sky made by man. The Nebra disk is used to measure the angle of the Sun at the poles.

Some theories say that it appears that ancient Europeans intentionally buried it thousands of years ago. At that time, they had been using this map for about 200 years and had even made some changes to hide some of the stars and add symbols to better accommodate leap months.

Archaeologists from the Goethe University in Frankfurt and the Ludwig-Maximilian University in Munich have reanalyzed all data related to the reconstruction of the discovery site and the surrounding circumstances of the area where the ancient copper disc was discovered.

The researchers’ findings show that the disk must date back to the Iron Age that is, it is approximately 1,000 years younger than previously ᴀssumed. This makes all the previous explanations about the Nebra Sky bronze disc become obsolete.
