In the search for decades in outer space, scientists now claim that they have discovered the first molecular bonds formed at the beginning of the universe after a great blow.
Finding helium hydride ions (HeH +) in the fog of NGC 7027 ended with epic hunters of astronomers to find molecules that are difficult to understand in space.
"The lack of evidence of helium hydride in the universe has questioned our understanding of chemistry at the beginning of the universe," said astronomer Rolf Gusten. Science Alert, quoted on Friday, April 19, 2019.
"The findings now found have solved such doubts," he continued.
As soon as the Universe cooled nearly 14 billion years ago after Big Bang, the theory found that the ions of the light elements began to merge.
"In this metal-free and low-density environment, neutral helium atoms form the first molecular bond of the universe in helium hydride ions (HeH +) through radiation ratios to protons," Gusten and colleagues explained in a new paper.
How to identify
Scientists estimate that HeH + might be formed in the 1970s, but so far they have never been able to detect it.
According to the researchers, this was due to the fact that the Earth's atmosphere was fundamentally a barrier to the spectrometer (instrument for determining the wavelengths of various beams) based on the soil.
The Gusten team was able to overcome these obstacles at the same time as the German Astronomy recipient at Terahertz (GREAT) frequencies is able to fly from NASA's infrared astronomy (SOFIA) spacecraft strategy.
According to Gusten, GREAT is the only device that can make such a perception and can only see helium hydride in outer space if it is released first in the air.
"Someone or something can't make such a search from the Earth Observatory because the 149 μm Earth atmosphere is completely opaque," Güsten explained.
"So we have to go into space or use your instruments from the platform by flying at a certain height, such as SOFIA, which floats above the lower atmosphere," he continued.
