The question is on everyone's mind. People all over the world are devoting their lives to finding the answer. Does extraterrestrial life exist? There is evidence of habitable zones in the solar system and ways to learn about them, planets meeting certain conditions, and a wide range of reactions to discover the answer. These days, there is almost as much evidence that aliens may exist as there is for non-existence. Say no to plagiarism. Get a tailor-made essay on “Why Violent Video Games Should Not Be Banned”? Get the original essay Many exoplanets, planets outside our solar system, have been discovered using the Kepler space telescopes. So far, 47 of them have been found to meet Earth's habitability criteria. According to scientists who study light cast on exoplanets, specific color wavelengths will appear when certain elements are present. The appearance of oxygen or other elements necessary for survival could mean that life is present. However, it is possible that aliens have adapted to survive through the use of different chemicals, which scientists can put together without knowing they have found the answer. Life on Earth can and does exist in extreme environments. the case of extraterrestrial organisms. Certain types of archaea and other organisms can thrive in extreme conditions. The Curiosity rover concluded that ancient Mars was warmer and had the right chemicals and energy sources that helped life thrive. Jupiter's moon Europa has a 3,100 kilometer frozen ocean. The idea of ​​chemical reactions occurring when water interacts with the rock surface producing nitrogen, carbon, phosphorous and other gases could mean that life could persist in this environment. Previous findings have shown that radiation on Europa is destroying any chance of life, but new research has shown that just one centimeter of ice in areas of low radiation has been proven to contain amino acids essential for survival. Life also requires energy, as Europe's tidal bending can provide heat for chemical reactions that can provide energy. As for how humans would react to the discovery of extraterrestrial life, that depends on the circumstances. A study conducted by the American Association for the Advanced Science concluded that the majority of people would respond with positivity rather than outrage or fear. The difference in circumstances between discovering extraterrestrial life and encountering extraterrestrial life is very different. Vakoch, a psychologist who works on creating interstellar messages, has found that those who are secure in their beliefs are more likely to welcome extraterrestrial life.
