A new study from Austria is proving, that the sky disc from Nebra is really from the Bronze Age and not from the Iron Age, as two historians for prehistory Gebhard and Krause had claimed, that the sky disc didn't belong to the place, where it identified finding place should be. It should only have been a single finding without proper context, which should be dated to Iron Age.
After a new study from 13 austrian scientists there can be no serious doubt, that the Mittelberg in Nebra is the authentic finding place.
Judicial testemonies of the looter and the receiver, explorations of the State Office for Monument Preservation and Archeology in Saxony-Anhalt and markings in the area make it possible to locate exactly, where the sky disc was originally hidden.
The disc also has damages, which were inflicted only a shortl time before by the looter. The sediment of the finding place has also a high concentration of gold and cooper, which would only be the case if the sky disc had rested a long time in the ground.
Also soil samples of the finding place and samples from earth on the sky disc are fitting, also from a bronze sword and axe, which was confiscated together with the sky disc from the looter.
Also trace elements and lead isotopes of the sky disc are corresponding to with those of a copper deposit near Salzburg, which is known for copper mining from 18. till 9. century BC. The gold of the disc is originating from the Carnon River in Cornwall, where gold mining is documented for the 17./16. century BC.
The tin and lead isotopes are also corresponding with other artefacts of early Bronze Age.
Finally data from a radiocarbon examination of organic material from the sword are dating to 1600 BC.

So the Sky Disk of Nebra is still the oldest known concrete depiction of the Cosmos.
