The moon didn’t die as early as we thought


Using isotope dating and a method based on chronology of the lunar crater, which involves estimating the age of an object in space in part by counting the holes in it, the team determined that lava flowed into Oceanus Procellarum 2 billion years ago.

Chang’e 5 was China’s first lunar sample-return mission and the first survey to bring back lunar material since 1976. After launch at the end of November and Will return in early December 2020, it is one of at least eight phases in China’s lunar program to examine the full moon.

Nemchin said there is no evidence that radioactive elements that generate heat (such as potassium, thorium, and uranium) are in high concentrations under the moon’s mantle. That means that those elements may not be causing the flows in the lavas, as scientists think. Now, they will look for other explanations of how to create flows.

The history of the lunar volcano can teach us more about the Earth. Consistent with the giant impact force, the moon could become a chunk of the Earth so scattered that our planet collided with another.

“Whenever we get new or improved information about the age of lunar objects, that has a knocking impact not only on understanding the universe, but on volcanoes and even the general geology of other planets. , “he said Paul Byrne, an associate professor of earth and planetary science at Washington University in St. Louis. Louis, who was not involved in the study.

Volcanic activity is not just shaping what the moon looks like – those old lava beds that can be seen today as naked as large black patches on the moon’s surface – but can help respond. on the question of whether we are alone in the universe, according to Byrne.

“The search for extraterrestrial life in part requires an understanding of habitat,” Byrne said. Volcanic activity plays a role in the development of atmospheres and oceans, essential components of life. But what exactly it is new to us about the potential of life in any area will continue to be seen.
