Castelliere di Rupinpiccolo is an ancient earthen castle located in the province of Trieste in Italy. The place was home to a fortified settlement formed in the Middle Bronze Age. Archaeological evidence suggests that it was also active in the Iron Age, until the site was discovered in AD. It was abandoned around the 5th century.
According to the press release issued by the Italian National Institute of Astrophysics (INAF), two circular stones with a diameter of 50 cm were recently discovered at the entrance to the earthen castle. Daily heritage.
According to Paolo Molaro of INAF and researchers from Ca' Foscari University in Venice and ICTP, one of the stones represents the sun, while the other is a carved celestial map dating back to 1000 BC. It dates back to the 4th century.
German about stones Astronomische Nachrichten A study was published in the journal, in which the authors determined that the sky map depicts the sky above Rubinpicolo about 2,500 years ago, making this discovery one of the oldest known star maps found in Italy.
Ancient star map from Italy may lead to a black hole
The research team identified 29 inscriptions on the stone, which correspond exactly to the constellations Scorpio, Orion, Pisces, and Cassiopeia. Based on the angle of the marks, researchers believe the inscriptions may have been made by the same person using a primitive metal hammer and chisel.
The star engraved in the rock, identified as Theta Scorpio, disappeared from view due to its position low on the horizon in Castelleri di Rubinbeccolo. However, researchers discovered, with the help of the Stellarium program, which simulates the night sky, that this star BC. About 400, can be seen from the ancient inscription.
Inscription 29 is particularly interesting because it shows no connection with celestial models. Instead, the study's authors suspect that it may actually be a depiction of a supernova. From a fleeting phenomenon that suddenly appeared in the night sky for days or months at that time and then faded and disappeared.
If this is indeed the case, the researchers suggest that by tracking the focal point in the night sky, associated with Section 29, it would likely reveal a black hole left behind by the supernova explosion.
