Web17 dec. 2024 · It took 380,000 years for electrons to be trapped in orbits around nuclei, forming the first atoms. These were mainly helium and hydrogen, which are still by far the most abundant elements in the universe. Present observations suggest that the first stars formed from clouds of gas around 150–200 million years after the Big Bang. 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. ibiotics akutpflege
