Like all museums, the Natural History Museum in Bern, Switzerland is full of treasures. But this one seems to come from elsewhere. In an article published in the Journal of Archaeological Science, archaeologists indicate that they have discovered that a 3,000-year-old arrowhead, found in the Bronze Age in the Swiss village of Mörigen, had been made with metal… extraterrestrial . This very small weapon, only 39.3 mm long, would have been forged in iron from a meteorite that would have fallen on Earth, reports Le Figaro.
The metal used to make this arrow would therefore not come “from our planet”, specify the archaeologists who signed the study. They put forward a hypothesis to establish its provenance more precisely: the iron used by Swiss ironworkers three millennia ago, and which was therefore used to forge this weapon, could come from the Kaalijarv meteorite, which fell in Estonia at that time. .
New analysis reveals: an arrowhead found in the 19th Century in the late
When this meteorite fell on Estonia, it disintegrated into small pieces of iron, which could therefore easily have been cut to form small sharp arrows.
Meteoric iron isn’t the only extraterrestrial element in this little spire. A radioactive isotope, Aluminium-26, produced in supernovae, therefore only in space, has been detected. The whole forming a particularly unique object.
