It would have taken several cycles of star-birth and supernova explosions for there to be enough oxygen to be detected by our instruments today, considering the fact that the oldest stars - called Population III
stars - had extremely short lifespans of about 2 million years only.

These first-generation stars, called Population III
, would have been responsible for churning out the heavier elements that shaped the evolution of second-generation stars and the galaxies they lived in.
Stars typical of the first stellar generation, known as Population III
stars, are prime candidates as the source of all that energy.
Scientist Luigi Piro, the director of research at the Institute for Space Astrophysics said that one of the great challenges of modern astrophysics has been the quest to identify the first generation of stars to form in the universe, which they refer to as Population III
Papers address high-mass star formation by gravitational collapse of massive cores, the binarity of Eta Carinae, metallicity-dependent Wolf-Rayet winds, and an overview of cosmic infrared background and Population III
, among other topics.
The book concludes with the wider cosmological implications, including Population III
stars, Lyman break galaxies, and gamma-ray bursts, for each of which massive stars are believed to play a crucial role.
360 Heads of the secondary schools were taken as population III
of the study.
The three populations in this study were designated Population II, Population III
, and Population VII.
Problem behavior and psychiatric impairment in a developmentally disabled population III
: Psychotropic medication.
Over the past decade, a new type of star has emerged at the forefront of stellar astrophysics: Population III
. These were the first stars born in the universe, when the cosmos was only a few hundred million years old (S&T: May 2006, page 30).
