Scientists discover the remains of a large-scale fossil that has hidden in space – Science Exam – cnBeta.COM

According to foreign media reports, the first stars in the universe have disappeared for a long time, but their marks may still exist in space. Scientists believe they've found one. Researchers from the University of Swinburne in Melbourne, Australia, used Keck Observatory to carry out celestial archaeological work on space.

Through this observation with two of the world's most powerful telescopes, researchers have discovered "primitive gas clouds" in distant universities and appear to have no heavy elements, suggesting that they are "fossil remains "and Big Bang.

So how do you find fossil remains in space?

By studying gas clouds, scientists can have a deeper understanding of some of the earliest events in the universe. If these gas clouds are not destroyed by waste, then they can exist in the early universe.

The research team believes that they have found a substance that is almost free of heavy contaminated elements. But the fossil still has no waste levels that can be found – because it is completely clean – stating it comes from a very early universe and were not found in 1.5 billion years after the big bang.

Professor Michael Murphy, one of the Principal Investigators of the study, noted that the finding was significant because they needed to know if such clouds could last for millions of years without contagioning by several generations.

Only such gas clouds were discovered before this discovery – such a finding is usually accidental. Looking actively for gas clouds and showing that they are not harmed by heavy elements, the Murphy team proved practicable to detect them.

Indeed, this is the first time for researchers at the University of Swinburne to make such a finding. As early as 2016, the research team also used data on the super large Chile's telescope to discover a "almost primitive" gas cloud.

However, why these gas clouds are so clean, there may be some explanations: the cloud has been contaminated by one of the earliest stars in the universe, leaving only the remains of heavy elements . However, the telescope used by the research team can not find it; the other is the gas cloud. He passed through the galaxy for the first time so he was not contaminated by other stars.

Murphy said: "This is an exciting possibility, because of understanding how these gas support galaxies are a major problem in astrophysics. We want to prove this in the future by removing any galaxies near the cloud."
