Primordial behemoths, Population III - universe's first generation of stars, very different from modern, or Population I stars, formed from pristine hydrogen and helium gas, before heavier elements were distributed throughout the universe by supernovae and powerful stellar winds, bigger and hotter than modern stars. Most Population III stars are expected to have lived and died between about 100 and 400 million years after the Big Bang, after which there would have been enough heavy elements in the cosmos to form stars that are more similar to the ones we see today.
