Is there life on the moon?

The Moon, Earth's only natural satellite, is full of secrets. The moon, orbiting at 385,000 km and only 1.2% of Earth's mass, has fascinated people for centuries. In 1969, the first humans landed on the moon, but our knowledge about it is still limited. As we continue to look for another life in the universe, one question remains: could there be life on the moon?

When talking about life on the moon, you do not have to think that there could be some form of life – at least as we know it – on the surface of the moon, the absence of atmosphere prohibits the presence of liquid water. In fact, if you pour water on the moon, it will immediately evaporate or freeze.

However, the moon would have ice on the bottom of some craters. We are not talking about a huge plaice like the poles of our planet, but frozen water, mixed with regolith, this 1

0-m-thick layer of dust that covers the lunar soil. This water would come from the fall of meteorites and comets billions of years ago. In the polar cold at the bottom of the crater, where temperatures are around -230 ° C, this ice can be preserved forever.

But if the moon is partly made of earthy elements – we do not know 100% of its origin but it is likely that it formed after the collision of Earth with Thea, a planet the size of Mars – it should theoretically also have water and organic molecules, the elemental building blocks of life.

In the cave, pockets of liquid water may be located moon base. While the subsurface is a true permafrost that is frozen at -17 ° C at a depth of 2m, the temperature increases by about 1.75 ° per meter of depth. The underground water could also be kept liquid by underground friction.

If there are pockets of liquid water under the lunar bottom, they are most likely there for billions of years, which is enough time for life to appear and possibly develop into more complex shape. But even if there are lives in these water packages, it is still very unlikely that they would have an ecosystem whose wealth is comparable to that on Earth.

Until we return to the Moon and take viable samples to test for microbes traces of life, the answer to the question of whether there is life on the moon is unlikely, but perhaps.
