Such stars are likely to have existed in the very early universe (i.e., at high redshift), and may have started the production of chemical elements heavier than hydrogen that are needed for the later formation of planets and life as we know it.
Sellised tähed eksisteerisid tõenäoliselt väga varajases universumis (st kõrgpunanihke ajal) ja võisid alustada vesinikust raskemate keemiliste elementide tootmisega, mis oli vajalik hilisemate planeetide ja elu tekke jaoks sellisena, nagu me neid teame.
