Tut’s Extraterrestrial Dagger
In 2016, scientists used an X-ray fluorescent spectrometer on a dagger discovered in King Tutankhamun’s tomb way back in 1922. For decades the dagger had left scientists confused because it contained iron, which was rare because Egyptians rarely did anything with iron 3,300 years ago. Also, the dagger hadn’t rusted in thousands of years. But the analysis indicated that the dagger was made out of cobalt and nickel which came from a meteorite that had fallen to Earth.
