Is there alien life on earth?

Quick answer: Which animal can survive temperatures ranging from 150 ° C to absolute zero (-273.15 ° C)? If you think this living thing does not exist, rest assured that there are many people who have never heard of the pet. But it does exist.

Affectionately nicknamed the alien, the Tardigrada or Water Bear is just as common a human being as we are. They are tiny creatures, measuring millimeters, used to humid environments.

Weird

It is interesting to realize that the mouth of these little animals has a tubular aspect, with some small stylets attached. The diet is based on algae, plant cells or small invertebrates.

Another curious feature is that tardigrades are able to withstand a thousand times more radiation than either of us, and of course hold up to 6, 000 atm (atmospheric pressures).

Space travelers

These small strange animals can live for many years, as long as they pass an important phase of complete numbness when they dehydrate and “shut down” in the process called cryptobiotic. To get back to normal life they need to hydrate.

Because of all these bizarre characteristics of practically superpowers, these tiny animals have already been sent by NASA into space without equipment. And of those who went, a third came back alive. Maybe that's where the alien reputation comes from.
