While many archaeological discoveries are made through carefully conducted excavations, others occur in ways that are not ideal for archaeologists. The Nebra Sky Disc was discovered in 1999 when two treasure hunters, armed with metal detectors, illegally dug up a severely rusted bronze disc near Nebra, Germany, which took many years of research and scientific testing for the disc to be recognized as an extremely important archaeological find.
Although at the time of discovery it seemed nothing more than a piece of rusty bronze, the object offered scientists invaluable insight into how Bronze Age people perceived the world above them.
