NASA SHOCK: The moon retracts like a grape while moon tremors hit the lunar orb | Science | New

The moon's temperature inside the Moon's climate has caused the lunar orbit to shrink 50 m (150 ft.) In hundreds of millions of years. As the moon cools inside, its outer "wrinkles" and "shrivel" like dehydrated grapes turn into grapes. This incredible process causes cracking and breaking of the delicate surface of the Moon, creating tectonic faults. When parts of the crust separate, they move to adjacent parts of the surface, causing earthquakes, or rather, moonquakes.

According to Thomas Watters, a scientist at the Smithsonian National Museum of Air and Space in Washington, these lunar earthquakes can be incredibly powerful.

He said: "Our analysis provides the first evidence that these faults are still active and may cause moon shakes today, as the moon continues to cool and shrink gradually.

"Some of these earthquakes can be quite strong, around five on the Richter scale."

Lunar faults produce prominent escarpments or abrupt and visible visible banks of lunar orbit.

NASA said that the escarpments of the Moon looked like "small steep cliffs" that stretch for several miles at a time.

These incredible discoveries were published today (May 13) in the journal Nature Geosciences.

Dr. Watters led a study of seismometric data collected on the Moon by five Apollo lunar landing missions.

Astronauts from NASA's Apollo 11, 12, 14, 15 and 16 satellites have left seismometers on the moon to detect tectonic activity in the lunar orbit.

The Apollo 11 alone measured 28 earthquakes in total over a short 28-week period.

Earthquakes range from 2 to 5 on the Richter scale.

By examining Apollo data with new algorithms, Dr. Watters' team identified eight earthquakes within 30 km of a prominent lunar fault line.

Dr. Watters said, "We believe that it is very likely that these eight earthquakes were caused by slippery faults under the effect of stress accumulation when the lunar crust was squeezed. by global contraction and tidal forces, indicating that the Apollo seismometers recorded the contraction of the Moon. technically active.

In order to eliminate the possibility of a coincidence biasing the data, the researchers performed 10,000 simulations of Moonquake.

The researchers found less than four percent chance that the tremors erupted near the faults by coincidence.

In addition, the researchers found that the impacts of meteors on the Moon had created a different type of earthquake than natural seismicity.

John Keller, NASA's Goddard Spaceflight Center, said, "It's really remarkable to see how the LRO mission data from nearly 50 years ago was combined to advance our understanding of the Moon while suggesting future missions to study the inner processes of the Moon. should go. "

But the Moon is not the only object of our solar system to suffer the effects of shrinkage.

According to NASA, "huge" thrust faults on Mercury measure up to 1,000 km (600 miles) of light and over 3 km in altitude.

NASA said, "Since rocky worlds are expanding when they heat up and contract when they cool down, Mercury's big mistakes reveal that it was probably hot enough to be completely melted after training.

"Scientists who are trying to reconstruct the origin of the moon are wondering whether it is the same for the moon or if, on the contrary, it was only partially melted, perhaps with an ocean of magma on an inside deeper and heating more slowly. "

Quick facts about the moon:

1. To this day, the Moon is the only celestial object outside the Earth on which the human has set foot.

2. The gravitational effects of the Moon on our home planet create tides in the seas and oceans.

3. Scientists believe that the Moon formed after an object the size of Mars hit the Earth about four billion years ago.

4. There are more than 190 moons in our solar system and our moon is the fifth largest of all.

5. American astronaut Neil Armstrong was the first man to stand on the moon on July 21, 1969.

6. The average distance between our Moon and the Earth is known as Moon Distance (LD) and is 238,857 miles (384,403 km).

7. The Earth's orbit on the Moon lasts approximately 27.3 days.

8. At 4,500 meters, Mons Huygens is the highest mountain of the Moon.

9. The side of the Moon facing the Earth is known as the near side, while the other side is the big side, not the dark side as some call it.

10. The gravitational pull of the Moon at the surface is only about 17% of that of the Earth.
