a piece of the Allende meteorite which fell in Mexico in 1969. It contains the oldest known matter: 4.567 BILLION years old calcium and aluminium inclusions! The material formed during the early formation of the Solar System.
Polished, acid-etched sphere of an iron-nickel meteorite. The pattern of intergrown crystals is called a Widmanstätten pattern. I’m not sure I’ve ever seen it in a sphere before - looks like some of the crystals actually go from side to side and basically create circles on this surface!
Scientists discover origins of ancient Hopewell culture's meteorite jewellery
The native Hopewell culture, which thrived along rivers and streams in North America from 200BC to 500AD, is today survived by a number of beautiful artefacts made from exotic materials – including copper and silver.
But perhaps the most exotic Hopewell artefacts are those made from iron extracted from meteorites. It is not known how these artefacts were viewed among the Hopewell, but what is certain is that they were extremely scarce due to the fact that meteoritic iron is so rare.
In 1945, researchers discovered 22 beads made of meteoritic iron, hidden in a burial mound at the Havana site in Illinois. A number of studies over the following decades attempted to describe these mysterious beads, analyse their chemical composition and understand their significance for the Hopewell people. Read more.
