The moon is one of many heavenly bodies that exist in the universe, but since it revolves around the earth, it has been one of the most interesting objects of study for human beings. Granted, we haven’t been back on the moon since the last landing in 1972; the moon is still an important part of scientific research and there are still so many lesser-known facts about the moon.
From being an object that superstitions were based on in the far past to being an object of scientific curiosity, the moon holds significant importance.
Interesting Facts About the Moon.
1. The Moon Can Make You “Crazy.”
Around 300 years BC, it was found that the moon had a significant effect on ocean tides. Philosophers Aristotle and Pliny, the Elder, were sure that the human brain was mostly liquid, so the moon could have a similar effect on brains as it did on tides.
They believed that those tides in the brain could make people temporarily insane. However, during the 1980s, 37 different scientific studies were analyzed by a psychologist and an astronomer to test this theory. As expected, they proved the philosophers wrong. They concluded that the moon did not affect the brain. However, it is still the topic of research as the brain and minds are viewed differently by many scientists and researchers.
2. Jumping Water on the Moon
NASA’s Lunar Reconnaissance Orbiter (LRO) discovered water on the moon in 2009. An upgrade to this orbiter, the Lyman Alpha Mapping Project (LAMP), has shown that water molecules can travel around the moon as its surface warms and cools as the day goes by.
Apparently, during the midday, water that has remained as the ice starts to melt and heat up just enough for some molecules to get lifted into the atmosphere. It travels until it finds a cooler area and then settles back into the surface as ice. Makes you wonder what that would look like if it could be seen with naked eyes, huh?
Not mooncakes, moonquakes! According to NASA, as the moon’s interior cools down, it is shrinking. The moon has gotten about 150 feet smaller in the last several hundred million years.
Imagine a grape shrinking into a raisin, getting all wrinkly. But since the moon does not have an outer layer that is flexible like the skin of a grape, the crust of the moon breaks as it shrinks.
During this shrinking, one section of the crust is pushed over or under another section, creating hill-like structures. This is somewhat similar to what happens to tectonic plates during an earthquake. These moonquakes can be as strong as five on the Richter scale.
4. Moon Craters; War Remnants?
In Greek mythology, it is believed that Typhoeus, the son of Tartarus and Gaia, wanted to rule the earth by getting rid of every god that lived on it. They believed that Poseidon, the Titan of oceans and water, tried to stop Typhoeus as he came for the war, but he poisoned the waters altogether.
The sky gods had to end the war, including the stars’ spirit and Selene, the Titan of the moon. They believed that the moon was Selene’s chariot that she could ride across the sky and that the craters on the moon were leftover from when she rode the moon chariot into battle.
5. The Good Side of the Moon
Don’t worry if you have a good and a bad side because apparently, the moon does too! It has one side with a smooth and thin crust and another thick and dotted with craters.
Researchers have one possible reason for this; a giant body like an asteroid that crashed onto one side of the moon. They believe that this crash happened in the very early days of the moon.
By modeling 360 different collisions and comparing the results, they suggested that an object 500 to 560 miles across could have created this big crater.
6. Fresh footprints; Alien Existence?
The first-ever moon landing took place on July 20, 1969, and the last one in 1972. No man has been on the moon since then, but fresh footprints can be seen on the surface of the moon.
Although this might excite some people who believe aliens exist, they are just some leftover footprints. Since the moon does not have an atmosphere like the earth, these tracks last long.
7. The Scary Side
The moon looks calm and quiet from afar, but it can get really scary, really fast when you step foot on it. Moondust is a fine, electrically-charged powder than can be found on the moon’s surface.
This dust is so abrasive that it can cut through three layers of Kevlar-like material. This could get into the joints of astronauts’ suits and make them unable to move their limbs. It is also toxic to the lungs.
Astronauts have said that they couldn’t see their own hands and feet because the shadow on the moon is almost pitch black. What is creepier is they say that a light halo would appear around their shadows sometimes.
8. Rules for Naming Craters
The International Astronomical Union is responsible for naming the craters on the moon. They give these names surrounding a particular theme.
There are generally two groups these names can fall under; deceased scientists, explorers, artists, and scholars who are known for their contributions in their field and deceased American astronauts and Russian cosmonauts.
