An "alien" weapon? No, but it is extraterrestrial

 

I have to admit that the headline of this Daily Mail article intrigued me. 

'Alien weapon' made 3,000 years ago is found in Switzerland

Made by aliens? 

A laser cannon brought to Earth 3,000 years ago?

A sword with a handle made for an entity with three fingers?

No, it's not that exciting.  It's a weapon made on Earth, but made from an iron meteorite.

"The arrowhead - made out of a meteorite - was found by researchers from the University of Bern at an ancient Bronze Age site called Mörigen in Switzerland.

Geologists tested the artifact's composition, which includes aluminum-26, a short-lived isotope once abundant in the early solar system - but it is not naturally found on Earth."

In fact, it was probably made from a meteorite that fell in what is now Estonia.

This article from the Smithsonian magazine is somewhat more balanced.

So here's the little alien arrowhead.
