Nebra sky disk has always been known as “the oldest astrolabe in the world”, and has been listed as the world memory project by UNESCO. But according to a new study, people may need to rethink the description because its age is in doubt. < / P > < p > two archaeologists from the University of Frankfurt and the University of Munich Re examined the location and manner of discovery of the Nebraska astrolabe disk. The disc was found in an illegal excavation near Nebraska in 1999, along with a large number of Bronze Age objects, including swords and jewelry. If the age of the astrolabe matches the age of other objects, it is about 3600 years old. According to a news release this week from the University of Frankfurt, “the information given by the looters is vague.”. Wearing detective hats, the researchers investigated the findings and concluded: “astrolabes cannot be associated with other discoveries that seem to help date the world’s famous objects in the first place.” Archaeologists say there is not enough evidence to prove that the astrolabe was dated to the early Bronze Age, according to archaeologists. Instead, the researchers believe that the pattern of the disc coincides with the iron age, making it about 1000 years later than assumed. < / P > < p > the researchers published their analysis report “key comments on the discovery complex of the so-called nebular disk” in the journal arch @ logische Informationen. UNESCO has described the Nebraska astrolabe as “one of the most important archaeological discoveries of the 20th century”. The scientists behind the study are calling for a new critical discussion of the disk. It probably belongs to a different time and place. Global Tech
