Scientists raised by 20 times an assessment of abundance of the most ancient molecule in the Universe

Scientists carried out new measurements of destruction by electrons of a molecular ion of hydride of HeH%2B helium — the earliest connected condition of atoms in the Universe — and found out that they are much steadier, than was considered earlier, so during an era of emergence of the first stars concentration of HeH%2B was at least in 20 times more. It can significantly affect estimates of cooling of primary clouds of gas, and also demands revaluation of a role of a molecule in degradation of relic radiation, scientists in the Science magazine write...
