We have been searching for life on other space globes, including our natural satellite, Moon and our closest neighbor, Mars.

Moon is the only place after Earth where we, the humans have walked. The purpose was to find out if our moon can host life!

Space agencies are planning to land humans on Mars, too, in the near future to dig out the traces of life. NASA and their European counterparts are also extending their search for extraterrestrial life on some of the moons of JupiterSaturn and a few dwarf planets such as Ceres. These strange rocks have many awesome characteristics to support life.

Scientists and space watchers have time and again created the sensation with their not-so-reliable findings.

According to many conspiracy theories, aliens are already in contact with humans. If that is true, how easy it is for us to identify extraterrestrial life on Earth and in the outer space?

Finds of a Spanish University

A Spanish journal “Acta Astronautica” recently published a report about the finds of a study done by researchers at the University of Cádiz, Spain. A group of people was asked to spot the (signs of) human-made structures on alien land, and most of them spotted Earth-like creatures such as the famous waving gorilla or the (illusion of) human face on the top of a volcanic mountain on Mars.

Humans are so biased and have such a narrow definition of extraterrestrial intelligence (ETI) that it is hard for them to believe that aliens can be present in any form and may have an entirely different DNA or physical structure.

The reason behind the definition of ETI we have is basically the science fictions we read or watch. The visual representation of aliens has made us believe that aliens are an advanced version of humans. However, the fact can be miles away from our belief.

Telescopes and radio antennas to receive alien signals

NASA and other agencies have installed large radio telescopes to see and receive alien frequencies.

Amoeboid found below the thick frozen layer of water on a distant planet can also be an example of extraterrestrial life. Can single-celled creatures send radio signals or can it be spotted through a large city-sized telescope in the Earth’s orbit? Are the technology and approach we use to #search for extraterrestrial intelligence (SETI) really alien friendly? Are they advanced enough to spot aliens?

Characteristically, we have been searching for blue-red human-like creatures that we see in our movies. But, we need to understand that not every living thing in the universe can be a mirror image of creatures living on the Earth.

It’s all about the limitations of our imagination, say the researchers at the Spanish University.

The need is to broaden our search criteria to find brainy aliens. We need to peep into multiple directions following a multidisciplinary approach. But, what remains unquestioned here is, are we really open for that? Should we really contact aliens? #Alien life #how to spot an alien
