Question
If there are any Star Boffins reading El Reg, can they answer this:
Does this mean that there was a generation of stars with only hydrogen that fused into helium, went nova and spread that around?
This new helium went into making new stars which fused hydrogen into helium, and helium into Lithium, then they went bang, ekcetera...
So there may be even older shorter lived stars yet to be discovered?
