Scientists have discovered the first direct key organic elements in the comet with evidences about how life began on Earth, which confirms the theory that they were the heavenly bodies upon a time brought to Earth and throughout the solar system, researchers said on Saturday. Spacecraft European Space Agency’s Rosetta has repeatedly detected amino acid glycine by which living organisms synthesize proteins in a cloud of gas and dust around comet 67P / Churyumov Gerasimenko, the BBC reported.
Glycine has previously indirectly detected in the samples to Earth in 2006 fell from another comet Wild 2 samples discovered in the US state of Utah were contaminated, making it difficult to scientific analysis. “The fact that the glycine discovered more comets shows that not even the Wild 2 67P are no exceptions,” said Kathrin Altwegg of the University of Bern, who led the study published in the journal Science Advances.
The discovery indicates that the glycine common element in the parts of the universe where stars and planets, says Altwegg. “Amino acids are everywhere and life could arise in any part of the universe,” she said. Her team found and phosphorus, a key element in all living organisms and other organic molecules in the dust around 67P. This is the first time that some comets found phosphorus, said the BBC. Scientists long debate about the circumstances that led to the emergence of life on Earth billions of years ago, including the hypothesis that comets and asteroids with organic elements fall into the oceans on Earth in the early stages of its history.
The spacecraft of the European Space Agency (ESA) repeatedly detected amino acid glycine ensuring the living organisms synthesize proteins in the cloud of gas and dust around comet Churjumov-Gerasimenko (which means even as Churi, 67P / C-G or 67P) and can proved how life began on Earth. Glycine previously indirectly was detected in samples of earth fell in 2006 by another comet Wild 2. However, the specimens discovered in the US state of Utah were contaminated, which hampered scientific analysis.
“The fact that glycine was detected in more comets, indicates that Wild 2 67P or no exceptions.”, Says the BBC Kathryn Eltveg the University of Bern who managed the survey. The discovery suggests that glycine is a common element in the parts of the universe where stars and planets arise adds Eltveg. “Amino acids are everywhere and life could occur in any part of the cosmos,” she said.
