How were the first stars formed
Web19 mei 2024 · The very first stars likely formed when the Universe was about 100 million years old, prior to the formation of the first galaxies. As the elements that make up most of planet Earth had not yet formed, these primordial objects – known as population III stars – were made almost entirely of hydrogen and helium. WebBut beginning in the 1980s, large-scale surveys began to identify the small population of iron-deficient stars that likely formed in the first billion years following the Big Bang. Those surveys expanded the number of recognized stars with iron abundances less than 1% of the Sun’s; nowadays, many tens of thousands of such stars are known. 7 7. T.
