Such a prediction was given by Professor of Astronomy from the University of Arizona Chris Impey. Start the search should be in the solar system, but it is worth to prepare for the fact that extraterrestrial life may not meet our expectations.
In an interview with Futurism astronomer Chris Impey suggested that scientists will discover the first signs of extraterrestrial life in 10-15 years. However, encounters with the higher mind should not be expected. Impey sure that in space will be able to find only traces of microbial life.
The most probable foci of extraterrestrial life Impei considers objects in the solar system – it is with these that search should begin. First of all, scientists should pay attention to Europe – the ice-covered companion of Jupiter.
On Mars, according to the scientist, finding life will be extremely difficult, since it is most likely hidden beneath the surface. Moreover, life on the Red Planet could exist sometime in the past, and now it is possible to find only traces of her stay. Recently, a group of scientists studied samples of rocks collected by the Curiosity rover in the Martian Gale Crater, which was once filled with warm water. Researchers suggested that conditions suitable for life lasted on Mars about 700 million years and ended 3.1 billion years ago.
Outside the solar system, astronomers and physicists are exploring terrestrial-type exoplanets. Impey believes that the main object of research should be the atmosphere of these planets, and not their surface. Over time, technology will identify the presence of biomarkers such as oxygen and methane, which indicate the possibility of microbial life.
According to the astronomer, humanity has never before had such tools for exploring outer space, as it is now. “Any present experiment of the SETI project surpasses all other similar experiments combined,” Chris Impey believes.
Many experts are trying to find an explanation for the Fermi paradox and the many years of unsuccessful search for alien civilizations associated with it. The astronomer of the SETI project, Seth Shostak, believes that aliens may not be microbes or humanoid creatures, but robots. For this reason, scientists should not look in space for traces of extraterrestrial life, but traces of extraterrestrial technology.
