- Like their descendants, these stars were element-making machines, building new elements in their hearts as temperatures and pressures increased. When these stars exploded, after only a short lifetime, they scattered the newborn elements into the space around them, allowing the next generation of stars to incorporate that gas and dust.

Jan 13, 2021 · But those variations, literal ripples in the structure of the universe, are revealing how the first stars formed. Computer models show that the minuscule density fluctuations in the early...
The first generation of stars, often called Population III (or Pop III), form from metal-free primordial gas at redshifts z ∼ 30 and below. They dominate the cosmic star-formation history until z ∼ 15–20, at which point the formation of metal-enriched Population II stars takes over.
Jun 13, 2023 · Recent observations of GN-z11 by the James Webb Space Telescope have revealed hints that this galaxy harbors Population III stars—the first generation of stars to form in cosmic history.

How do clouds of gas and dust collapse to form stars? Why do most stars form in groups? Exactly how do planetary systems form? How do stars evolve and release the heavy elements they produce back into space for recycling into new generations of stars and planets?
Jun 17, 2015 · A team of astronomers has found the best evidence yet for the very first generation of stars, ones made only from ingredients provided directly by the big bang. Made of essentially only hydrogen and helium, these so-called population III stars are predicted to be enormous in size and to live fast and die young.
