What did scientists find on the Murchison meteorite that fell in Australia?


The Murchison meteorite is one of the most important objects that fell to Earth. The results of studies of a celestial body still cause fierce controversy in the scientific community and significantly change the idea of ​​the evolution of living nature.

The Murchison meteorite fell to Earth back in 1969. However, it attracted close public attention only a year ago, when American scientists

The solar system is believed to have formed from the debris of a once-deceased star 4.6 billion years ago. Thus,

Based on the fact that stars live for several billion years, the Americans concluded that before the formation of the Sun, space experienced a period of active star formation, a kind of «baby boom» 5-7 billion years ago.

The main and truly intriguing news was the fragments of fossil organisms found in the structure of the meteorite. The first organic inclusions in a meteorite

Studies have shown the presence of nucleic acids in the stone, similar in structure to the DNA and RNA of terrestrial organisms. Also, scientists have found amino acids on the meteorite — the «building blocks» of proteins, and hydrocarbons — the basis of organic chemistry.

In 2008, Japanese scientists

Cyanobacteria or blue-green algae are unicellular organisms, the first inhabitants of our planet. It was they who, in the process of photosynthesis, enriched the atmosphere with oxygen and gave impetus to the emergence of aerobic life.

If cyanobacteria are indeed present on the Murchison meteorite, then

Moreover, space is overflowing with such meteorites, and for the formation of life, suitable conditions are sufficient and the fall of this object on the surface of the planet. It turns out that even the planetary systems closest to us should be inhabited by different organisms!

The study of the Murchinsky meteorite is of great importance to both astronomers and society as a whole, and scientists will continue to study other meteorites to search for extraterrestrial life.
