    Yes. But the context is:

    The oldest of the dust grains were formed in stars that roared to life long before our Solar System was born.
    ...
    When stars die, particles formed within them are flung out into space. These "pre-solar grains" then get incorporated into new stars, planets, moons and meteorites.
    Down with racism. Long live miscegenation!

      As in a nova or a supernova?

      That's when most of the metals* are produced from the primordial hydrogen, helium, & touch of lithium.


      *Where "metals" are elements that are not H, He, or Li.
      Li is a metal
      H gets metallic properties close to absolute zero

          Some of the Lithium around today was formed in the first few minutes after the Big Bang:
