The earliest existing stone was probably found in specimens from a moon rock brought to Earth by astronauts in 1971.

"This is an extraordinary discovery which helps to paint a picture of the primitive Earth and the explosion that has transformed our planet at the dawn of life "- said scientist David Kring of the Lunar and Global Institute.

Researchers are about 4 billion years old. According to an international group of scientists, it is proven that the stone of terrestrial origin is a piece of quartz, feldspar and zircon of 2 grams, which is deposited in a larger piece of rock called Great Bertha – minerals which are rare on the Moon, but are distributed on planet Earth. The flickering of zircon was particularly useful because zircon contains uranium, the known half-life of which allows precise dating. Further chemical analysis showed that the stone was formed in an oxidized system, similar to the Earth, at terrestrial temperatures and not at the temperature conditions of the Moon.

According to scientists, it would have been launched from Earth about 4 billion years ago when an asteroid or comet crash in a young planet, sending fragments of rocks into l & # 39; space. It should be noted that the Moon was then three times closer to the Earth. A piece of rock formed under the surface of the planet at a depth of about 20 km, where it remained, until a powerful blow did not occur. did not shake in the space.

9 billion years ago. Then he came to the surface about 26 million years ago and the astronauts discovered it decades ago and then went home

Reminder that scientists have recently recorded the # 39, history of the fall of a meteorite during the lunar eclipse.

As stated earlier, the European Space Agency (ESA) is planning its own landing on the Moon by 2025.

Previously, the Chinese machine had planted the first plant on the Moon. The cottonseeds were delivered to the surface of the satellite by the Chang-e-4 aircraft, recently manufactured for the first time in the history of landings on the back of the moon. Unfortunately, the germs did not last long.
