What will Aliens look like? A Secrets Reveal by Astrobiologists

If we were to discover extraterrestrial life someday, this would be undoubtedly become the greatest find in the history of mankind. While most science fiction works predict that a contact with aliens could end very badly, there is no shortage of those who prefer to apply optimism.

In any case, one of the most enigmatic questions related to this subject is what would be the appearance that these extraterrestrials would have.

The question has been formulated by the Gizmodo portal to several astrobiologists within the context of a recent theory that arose contemplating the possibility that there is microbial life on a moon of Jupiter and in another one of Saturn.

“We should not expect to see a duplicate of Homo sapiens when we look for life outside of the Earth,” said Doug Vakoch, president of METI International, a scientific and educational research program on Sending Messages to Intelligent Extraterrestrials (METI) and Search for Extraterrestrial Intelligence (SETI).

Life on Enceladus

Vakoch does not rule out the existence of life under the icy bark of the Enceladus, a moon of Saturn, which feeds on the hydrogen that emerges to the surface. “But the waters of the Enceladus are so cold that it would be difficult to imagine a life greater than a bacterium,” he explained.

Rocco Mancinelli, a NASA astrobiologist, agrees with Vakoch in stating that “the Enceladus environment does not allow for multicellular life forms.”

SETI’s main astronomer, Seth Shostak, suggests that the alien life form that could most resemble aliens would be insects.

In turn, Caitlin Ahrens, an astrophysicist at the University of Arkansas (USA), thinks that alien life should not necessarily be carbon-based, as it is on Earth. For example, some extraterrestrial creatures could be composed basically of a chemical element like the sulfur.
