Hypatia Stone - Somewhat Unusual!

A stone found in the deserts of Egypt and named after the first female astronomer has a composition unlike anything seen on Earth - no silicates, tiny diamonds, metallic aluminium, silicon carbide and a nickel phosphorus compound.

You can read about it HERE. The original paper abstract can be found HERE.

It probably formed in a very cold environment, from materials that predate the Sun. But was the original meteorite formed after the Sun?

So lots of unknowns and opportunity for speculation!
