Dagger in Tutankhamun's tomb was made with iron from a meteorite - Guardian
A dagger entombed with King Tutankhamun was made with iron from a meteorite, a new analysis on the metal composition shows.
In 1925, archaeologist Howard Carter found two daggers, one iron and one with a blade of gold, within the wrapping of the teenage king, who was mummified more than 3,300 years ago. The iron blade, which had a gold handle, rock crystal pommel and lily and jackal-decorated sheath, has puzzled researchers in the decades since Carter’s discovery: ironwork was rare in ancient Egypt, and the dagger’s metal had not rusted.
Italian and Egyptian researchers analysed the metal with an x-ray fluorescence spectrometer to determine its chemical composition, and found its high nickel content, along with its levels of cobalt, “strongly suggests an extraterrestrial origin”. They compared the composition to known meteorites within 2,000km around the Red Sea coast of Egypt, and found similar levels in one meteorite.
