The moon didn’t die as early as we thought

Use isotope dating and based techniques Chronology of Lunar Craters, Which involves estimating the age of objects in space by calculating craters on its surface. The team determined that lava flowed into Oceanus Procellarum 2 billion years ago.

Chang’e 5 is China’s first lunar sample return mission and the first probe to bring back lunar material since 1976. Started in late November with Return in early December 2020This is one of at least eight stages in China’s lunar plan to explore the entire moon.

Nemchin said there is no evidence that there are high concentrations of heat-generating radioactive elements (such as potassium, thorium, and uranium) beneath the moon’s mantle. This means that these elements may not cause these lava flows as scientists believe. Now, they will have to find other explanations about how flows are formed.

The volcanic history of the moon can teach us more about the earth. According to the giant impact theory, the moon may be just a large piece that was knocked loose when the earth collided with the earth.

“Whenever we get new information or improved information about the age of material on the moon, it will not only have a chain reaction, but it will not only understand the universe, but also the volcanic activity on other planets and even general geology,” said Paul Byrne, Associate professor of planetary science at North Carolina State University, he was not involved in this research.

Byrne said that volcanic activity not only shaped the appearance of the moon — those ancient lava beds are visible to the naked eye today as huge black spots on the surface of the moon — and may even help answer the question of whether we are alone in the universe.

“The search for extraterrestrial life requires an understanding of habitability to a certain extent,” said Byrne. Volcanic activity plays an important role in the cultivation of the atmosphere and ocean, which is a key component of life. However, it remains to be seen what these new discoveries tell us about potential life elsewhere.
