    Johns Hopkins Scientist Finds Elusive Star with Origins Close to Big Bang



    I didn't know stars could last trillions of years.

    8ball Considerably more oppressed than yow

    I’m being pedantic again, but isn’t *everything* made from materials spewed out from the big bang?

    Sprocket. Regret, transience and disillusioned fortitude..

    Theoretically. :)

    They mean the elements created in the big bang, i.e. nothing beyond lithium.

    HAL9000 you seem to know your onions. Is this real?

    Yes, the claim that it is momentarily greater than the total power output of the observable universe is correct, though they understate the power output by ~3 orders of magnitude. See earlier thread here.
    They mean it is a pristine, first generation star formed purely of material arising from primordial nucleosynthesis. All the stars in our neighbourhood also contain heavily reprocessed material from previous generations of stars - our own Sun is most likely a third generation star (judging from its composition).
