Ancient mysterious object could be the key to uncovering supernova events from thousands of years ago that are no longer visible. The discovery is in the form of a carved stone disc found in Italy. Researchers believe that this artifact represents a depiction of a night sky map. This finding was reviewed in a study published in the journal Astronomische Nachrichten, as reported by Newsweek on Thursday (4/1).

The castle in Rupinpiccolo is believed to have functioned as a fortress between 1800/1650 BC and 400 BC. Although the exact age of the stone cannot be determined with certainty, it is likely that the stone disk originates from a specific period, indicating an age of at least 2,400 years. The stone disk shows clear traces of being carved by human hands and does not appear randomly scattered, as conveyed by researchers.
