I'm sure a few of these are debatable, but that aside, this slide show is amazing. The timeframes, the craftsmanship, the materials they used, it's all incredible and a good representation of human ingenuity in its infancy.

A couple of things about that link. First it talks of the oldest things on Earth - and then promptly follows with an article about a star thousands of light years from Earth. 

 

Secondly and more interestingly it says the star is old because of its low Fe content. Do you know why this would be? I'm no astronomer but I am aware that Fe is the element with the most stable nucleus of them all. I would naively have expected the amount of Fe to increase with time, rather than decrease.
