A new analysis of ancient treasures uncovered in Spain has revealed some of the artifacts were made with ‘alien metals’ 3,000 years ago.
Scientists conducted a new analysis of the Treasure of Villena, a hoard of 59 gold-plated objects found in 1963, finding two objects featured meteoric iron.
Meteoric iron is an early-universe protoplanetary disk remnant found in meteorites made of iron and nickel.
A gold-coated cap and bracelet contained the extraterrestrial material from a meteor that crashed into Earth one million years ago, according to the team’s estimates.

The study explained that meteorite iron is found in certain types of stony meteorites, composed mainly of silicates – a salt made of silicon and oxygen.
‘Since they come from outer space, are composed of an iron-nickel alloy with a variable nickel composition greater than five percent by weight,’ researchers wrote.
‘They also contain other minor and trace chemical elements, cobalt being one of the most significant.’
Using fallen meteorites to fashion objects was a common practice thousands of years ago, as a similar artifact was found in the tomb of Tutankhamun.
The Treasure of Villena was discovered on the Iberian Peninsula, revealing a look at when people shifted from stone to bronze.
However, the trove likely belonged to an entire community and not a single royal family.
About 90 percent of the collection was made with 23.5-carat gold and includes eleven bowls, three bottles, and 28 bracelets.
The artifacts were discovered by archaeologist José Maria Soler in December 1963, while he and his team were excavating a dry river bed called the ‘Rambla del Panadero’ – about seven miles from Villena.

Researchers found a cap and bracelet that featured meteoric iron – the former had 5.5 percent and the latter just 2.8 percent
Study senior author Ignacio Montero Ruiz, a researcher at Spain’s Institute of History, told Live Science: ‘The iron technology is completely different to the copper-based metallurgy and to the noble metals (gold and silver).
