The timeframes, the craftsmanship, the materials they used, it's all incredible and a good representation of human ingenuity in its infancy.

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.

Deepwater6 Posted March 21, 2018 Author Report Share Posted March 21, 2018 I thought that odd as well, once a star starts to create iron it's pretty much doomed, and I would think the closer it gets to it's demise the more Fe it produces.
