???? Traces of extraterrestrial life have fascinated scientists and the general public for decades. The vast and mysterious universe could harbor life forms beyond our planet. Technological advances and recent discoveries have rekindled hope of finding signs of extraterrestrial life. From the search for microorganisms on Mars to the analysis of exoplanets in the habitable zone, astronomers are intensifying their efforts to detect traces of life. Space missions, cutting-edge telescopes and studies of planetary atmospheres are invaluable tools in this search. The discovery of extraterrestrial life would represent a major scientific revolution that would change our understanding of the universe and our place in it. Theories abound, hypotheses multiply, but one question remains: are we really alone in the universe? Every day, researchers scan the stars for the slightest clue, hoping to one day answer this fascinating enigma. ????

In 1950, while discussing the possibility of extraterrestrial life with his friends, Fermi formulated a series of questions: Today they are known as the Fermi paradox. Why have we not found any trace of extraterrestrial life when the Sun is far from being the oldest star in our Galaxy? Other civilizations must have lived before us. Even if they have already become extinct, why have we not found any trace of them? According to scientists, humanity on Earth could have been detected from the confines of the Solar System. Over the years, there have been many hypotheses to answer the Fermi paradox. The most radical is that the probability of the appearance of life may ultimately be very low, and that the Earth was the only winner in this lottery. Perhaps we are really desperately alone in the Universe. But there are other hypotheses. Perhaps life began elsewhere, but was wiped out by cosmic events. It could never reach the advanced state we know today on Earth. Perhaps extraterrestrial life exists, but only in the form of microbial, plant, mineral or animal life. Or perhaps intelligent life exists, but interstellar travel is impossible or prohibited by extraterrestrial civilizations. Perhaps extraterrestrials are unable or unwilling to establish contact with us. They may simply not have found us yet. We may not even be on their list of potentially habitable planets to explore. Other civilizations may have developed differently than we have. They have not developed technology similar to ours, so they have devised alternative means of communication, for example. Or, on the contrary, perhaps it is we who are not technologically advanced enough. Perhaps we are unable to detect extraterrestrial life. Extraterrestrials send us signals, but we are unable to detect them. Perhaps there is life elsewhere, but it is undetectable. For example, at the bottom of an ocean protected by a layer of ice. Perhaps, on the scale of the Universe, the search for extraterrestrial life from Earth is still too new. Perhaps we are the first intelligent life form in the Universe, and others will follow, but by then our civilization will already be extinct. We will not be around to see it. Perhaps aliens avoid us because they are afraid of us. Or perhaps... aliens are already among us...? io This channel is an official affiliate of the ORBINEA STUDIO network.
