In the center of the Milky Way, the nitrile that forms RNA has been discovered

The new discovery of life-forming molecules that have been recorded at the center of our galaxy could have an impact on our understanding of how Life appeared on earth.

The emergence of life on our planet is still a mystery. One copy indicates that RNA (organic chemical compounds) created in a “molecular soup” consisting of, inter alia, methane, carbon dioxide and water hundreds of millions of years ago – this is called RNA World . Hypothesis.

It seems that scientists will not receive direct evidence on Earth to support the above hypothesis, but evidence can be sought outside our planet. source RNA prebiotic molecules (Nitrile) on Earth can be meteorites and asteroids.

In the distant past, the Earth was bombarded with all kinds of cosmic bodies. Indeed, scholars have stated that some meteoritesCurrently in our area Solar SystemThere are prebiotic molecules. As you know, meteorites or asteroids can form in dense molecular clouds.

It is especially interesting for this type of research Space Cloud G+0.693-0.027 There is no evidence of stars forming there yet, but scientists believe they may start forming there in the future. As Dr. Rivella says, “This means that her research (G + 0.693-0.027 cloud – ed.) can give us important insight into the chemical components that were available in nebulaWhich in turn led to the emergence of our planetary system. –

Scientists by studying the nebula have discovered a number of nitriles, including Cyanic acid, cyanoaline, propagrel cyanide and cyanopropene, as well as cyanoformaldehyde and glycolonitrile. This indicates that The basic building blocks of RNA can be found in space cloudsWhere stars and planets are formed.

– So far we’ve discovered some straight lines ribonucleotide precursorThe basic building blocks of RNA. But there are still key molecules missing that are difficult to detect. For example, we know that the origin of life on Earth likely required other particles as well, such as FatsResponsible for the formation of the first cells. Therefore, we should also focus on understanding how lipids can arise from simpler precursors available in the interstellar medium. – said astrobiologist Izaskun Jiménez-Serra, also of the Spanish National Council Ds. National Institute of Aviation Technology.
