Space discovery: Astronomers detect 'holy grail' of oxygen in the universe's oldest galaxy 1

According to the University of Swinburne in Australia, the spectral lines of a specific element always occur on the same wavelength.

As a result, astronomers were able to detect oxygen spectral lines in the light hitting Earth from G09.83808.

Leiden University said in a statement: “The new atomic oxygen spectral line has been seen as a holy grail for 20 years, but the galaxies really have to be far away.

“For not too distant galaxies, the light from the oxygen line does not penetrate through the Earth’s atmosphere.

“But, even when galaxies are very far away, you need very good telescopes in a high, dry place.”
