NASA orbiter has discovered a strange cave on the moon.
Deep passages from the surface lead to a whole network of catacombs. They are large enough to accommodate an entire city.
Moreover, the caves have their own climate: it is assumed that a space suit is not needed here, and a person can walk just in pants and a sweater.
The temperature on the surface of the moon varies from +130 to -173 degrees Celsius, which makes it completely uninhabitable. In the catacombs, the constant temperature is kept at +17 degrees.
Apparently, the caves were formed from lava tubes – objects that arose after volcanic eruptions.
At the same time, the dimensions of the found cave are huge. The lava tube (if this is it) stretches for 50 kilometers. The ceiling height exceeds 75 meters.
The catacombs on the satellite are the oldest of all mankind: they were formed at least 3.5 billion years ago.
“This is not a place for a temporary base. The catacombs can easily fit a whole city. Some astrophysicists joke that it is already there,” Dr. Honshu Kaguya, one of the authors of the discovery, told reporters.
American astronauts are planning to check the caves soon. A new lunar mission should take place before the end of the 30s.
