How did the moon form? Recent discoveries show that the history of our natural satellite is much more amazing than we thought: intense primary magnetic field, still recent volcanism, axis tilt ...

There are different versions of the formation of the moon. One hypothesis suggests that the moon came from an accumulation of small particles of cosmic dust. Another version claims that the Moon came from a powerful impact of the Earth with a meteorite, and is a fragment of the earth's crust. However, these versions are not confirmed, since no similarities were found between the chemical composition of terrestrial and lunar rocks.

The moon has no atmosphere, there is no oxygen. Life on the moon is impossible. It is covered with debris of cosmic bodies and a layer of cosmic dust. A person on the surface of the moon can only be in a special spacesuit. The temperature there reaches around 250 degrees of heat during the day, and at night the temperature drops to 150 degrees of cold. The main factor why a person cannot be on the moon is solar radiation, the level and strength of which have a fatal effect.

The moon is under constant observation by astronomers. Its strong magnetic field, volcanoes on the surface, movement around the Earth, all this still raises a lot of questions among scientists.

In all cultures of the past and present, the Moon occupies a special place. Its proximity to Earth, the ever-changing alternating monthly cycle, the new moon and the full moon have generated many myths and beliefs. She also inspired many artists.
