The fickle and changeable night light has long attracted the attention of people who are interested in the unknown, secret, unsolved. Despite numerous studies conducted, some of the mysteries of the moon remain unsolved. Why do moon shadows look deeper and richer? Where did the "obelisks" appear on the surface of the satellite, obviously of man-made origin?
Satellite origin
Many secrets of the Moon are of interest to researchers, but the most impressive mystery remains the origin of the astronomical object. On this score, there are several theories, each of which may turn out to be correct. Some scientists are of the opinion that the Moon once broke away from our planet. They believe that the Pacific Ocean formed in place of the missing fragment.
There is a version that the Earth at one time collided with the forming protoplanet called Theia. As a result of the "space accident", a cloud of dust and debris was formed, which then turned into a familiar night star.
Why do moonquakes happen?
On our planet, the cause of an earthquake is tectonic plate shifts. However, such formations do not exist on the Moon, while moonquakes are observed quite often. What caused this phenomenon? Experts believe that the gravity of the Earth and its tidal activity are to blame.

Moonquakes can be triggered by solar activity, as well as by the impact of meteorites. However, even the most significant fluctuations rarely exceed 5.5 points on the Richter scale. This is enough to make small objects vibrate. The average duration of the tremors is about 10 minutes.
Artificial constructions
Many researchers rack their brains whether there is a UFO and whether representatives of an extraterrestrial civilization visit the satellite of our planet? This theory is supported by one of the secrets of the moon, discovered with the help of various satellites. Scientists managed to notice strange things on the surface of an astronomical object.
These are structures in the form of a parallelepiped with a height of several meters to 1.5 km. There is a version that these buildings were abandoned by representatives of the extinct ancient civilization. Others attribute their construction to aliens. However, the official NASA secrets of the Moon are not impressive, they believe that the pictures of mysterious objects are fake.
Moon dust
It is a very insidious substance, as small as flour, but with a dense and rough texture. It can penetrate almost anywhere. Moon dust is a problem for astronauts.
It can penetrate into the compartments of the ship and even inside the spacesuit, which leads to the appearance of allergic reactions.
It is believed that even the most durable steel object will become unusable if it is in contact with moon dust for a long time. This unusual substance smells like burnt gunpowder.
A shadow that absorbs objects
Many of the mysteries of the moon are explained by very rational reasons. Astronauts Buzz Aldrin and Neil Armstrong had an interesting discovery during their first visit to the moon. They found that local shadows are much darker and richer than terrestrial ones (later it turned out that this is a consequence of the lack of atmosphere).
As soon as a man stepped into the shadow, he ceased to see his own legs. And this is even despite the presence of a bright solar disk in the sky. The unusual optical effect made many of the spacecraft's maintenance tasks much more difficult.
Man is not given to fully clarify the secrets of the universe and the mysteries of the universe. The deeper we penetrate into space, the more questions appear that have no answers.
