- New Observations of Recently Active Wrinkle Ridges in the Lunar Mare
– The surface of the Moon features various tectonic features, including lobate scarps and wrinkle ridges, which have formed due to compressional stresses on the lunar lithosphere.
– Recent evidence suggests that these features have been recently displaced and formed, indicating ongoing geological activity.

- Lunar Landscape: Wrinkle Ridges
– Wrinkle ridges on the Moon are related to stresses induced by mare basalt-filled basins and predominantly extend along NW or NE orientations.
– The far side of the Moon has very little mare (lava plains) compared to the near side, which may be due to a thicker crust and less volcanic activity.
– One theory suggests that a dwarf planet impact deposited radioactive isotopes on the near side,facilitating more volcanism and mare formation.

Unveiling the Secrets of the Moon’s Far Side: A Geological Mystery
The moon, our closest celestial neighbor, has long been a subject of interest and scientific inquiry. Recent findings have shed new light on the geological history of the moon’s far side, revealing intriguing details about its formation and evolution. A team of researchers, including those from NASA, has identified 266 wrinkles on the remote side of the moon, providing valuable insights into the lunar landscape.
A Closer Look at the Moon’s Wrinkles
The remote side of the moon is characterized by ridges that are considerably smaller than those on the near side. These ridges measure about 100 meters in width and stretch up to 1,000 meters in length. Notably, these wrinkles appear in clusters of 10 to 40, a pattern that is much smaller compared to their near-side counterparts.
Age and Formation: A Geological Enigma
One of the most intriguing aspects of these findings is the age of the wrinkles. despite the assumption that the far side of the moon formed together with the near side, these wrinkles appear much younger.This discrepancy challenges conventional geological theories and suggests that the moon’s far side has experienced more recent geological activity.
The Science Behind the Discoveries
Geologists use various methods to determine the age of lunar features. One such method involves counting craters. The logic is straightforward: older features will have more craters, while younger features will have fewer craters. According to this method, the wrinkles on the far side are estimated to be between 84 million and 160 million years old. This age range indicates that the volcanic activity on the far side must have occurred relatively recently, within the last few billion years.
Implications for Lunar Geology
The discovery of these wrinkles and their age has significant implications for our understanding of lunar geology. It suggests that the moon’s far side has been more geologically active than previously thought. This new information can help scientists refine their models of lunar formation and evolution.
Visualizing the Findings
To better understand the scale and distribution of these wrinkles, refer to the table below:
| Feature | Near Side | Far Side |
|————————–|———————————–|———————————–|
| Width (meters) | Up to several kilometers | About 100 meters |
| Length (meters) | Up to several kilometers | Up to 1,000 meters |
| Number in Clusters | Fewer clusters | 10 to 40 per cluster |
| Estimated Age (millions of years) | Varies | 84 to 160 million |
Conclusion
The moon’s far side continues to reveal its secrets, challenging our understanding of its geological history. The discovery of these wrinkles and their age provides a new piece of the puzzle, helping us piece together the story of the moon’s formation and evolution. As we continue to explore and study our celestial neighbor, we uncover more about the universe and our place within it.

The Chang’e 5 Mission: Unveiling the Moon’s Recent Volcanic Activity
The Chang’e 5 mission marked a significant milestone in lunar exploration.This Chinese mission successfully returned moon material samples to Earth, collected from around the Rümker Mons volcanic dome in Oceanus procellarum, a vast lunar mare. The analysis of these samples revealed volcanic glass beads in the regolith,indicating volcanic activity approximately 123 million years ago,with a margin of error of about 15 million years.
If these findings are accurate, they suggest that the moon is still contracting as heat slowly escapes from its interior. This ongoing contraction could lead to continued volcanic activity, even in the present day. Moonquakes, detected by seismometers placed on the lunar surface during the Apollo missions, provide evidence of this geological activity. Severe moonquakes can pose risks to human activities on the moon’s surface, prompting astronauts to avoid particularly hazardous areas.
The findings were published on January 21 in the Journal of Planet Science. This discovery has profound implications for our understanding of the moon’s geological history and its potential for future human exploration.
