Moon
It is the fifth largest moon in the solar system.
In size, it is second only to Ganymede, Titan, Callisto, and Io.

On its surface, there are both geologically young areas and much older, darker, and covered with many craters.

The Earth is therefore a slightly flattened ball - this shape is called a geoid.
Cosmos
The development of the universe can be divided into five stages.
The very early universe lasted only a picosecond, during which time the laws of physics that we know today had not yet developed.

The Moon's magnetic field is over 100 times weaker than the Earth's and ranges from 1 to 100 nanotesla.
It is not dipolar, so it is assumed that its source is not the nucleus but the crust.
Fungi

Cordyceps species are parasitic fungi that live on animals - insect larvae or spiders - using them a ...
