Are we Alone in the Universe? Or is there some extra-terrestrial intelligent life out there somewhere in the Universe? What are the chances that we will ever be able to find a so-called techno signature and evidence of advanced technological civilizations? How are scientists searching for life elsewhere in the universe? What is science doing about it? Scientists are engaged in finding answers to these questions, bearing on the deepest secrets of the nature and destiny of mankind, under the assumption that there is in fact, life out there to be explored. The search of extra-terrestrial life (SETI) The search for extraterrestrial life is a persuit of extraordinary importance, partially in light of the potential significance of success. The search for evidence of extraterrestrial intelligence (SETI) is placed in the more extensive galactic context of the search for extrasolar planets and biomarkers of primitive life somewhere else in the universe. A decision tree of possible search strategies is introduced just as a concise history of the search for extraterrestrial intelligence (SETI) projects since 1960. The attributes of 14 SETI projects currently working on telescopes are talked about and analyzed. Plans for a SETI search in the future are laid out. Plans for progress, the significance of invalid outcomes, and a few opinions on the deliberate transmission of signals are additionally included. SETI results to date are negative, yet in reality the quest has only started yet. SETI scientists are busy calculating the likelihood of their contact with extra-terrestrials through radio frequencies, using Drake Equation, presented the 1960s by Frank Drake of the SETI institute in California, it has helped scientists from SETI plug in their best guesses and, estimate that there about 10,000 civilizations out there in the galaxy, sending signals our way – which has led scientists to believe that we will, sooner or later, detect alien signals within a decade or two. This optimism relies on the probability of life arising on suitably habitable planets that is always taken to be 100%. SETI 2.0 and the odds of discovering intelligent aliens 2020 has been an interesting year as far as the search for extraterrestrial intelligence is concerned. We actually haven't been able to track down an alien sign yet, but researchers have been working with new technologies and systems that are expected to extraordinarily improve the process. Early in 2021, they revealed they have amassed a ton of new survey data to go through, collected in the past few years by radio telescopes. A blueprint for new approaches to the question of alien intelligence was announced by the National Radio Astronomy Observatory (NRAO) in mid-February 2020. The old SETI paradigm of just looking for radio signs is changing as new technology is used and novel thoughts are thought of. Additionally, in mid-February, the Breakthrough Listen initiative reported by means of UC Berkeley that an astounding 2 petabytes (2 million gigabytes) of information was delivered from the most recent SETI study of our universe which is thought to be the most extensive overview yet of radio emissions from the plane of the galaxy and the area around the central black hole. As a component of the new technological advancements, the SETI Institute will add another signal-processing system to the Very Large Array. However, what are the odds of life and intelligence emerging beyond our planet or are we really alone? From the developments of various nearby stars we have now detected unseen companion bodies orbiting around them that are probably pretty the size of large planets. From our insight into the processes by which life emerged here on the earth we realize that comparable processes should be genuinely regular all through the universe. Since intelligence and technology have a high survival value it appears to be likely that primitive life forms on the planets of different stars, evolving over a long time, would at times create intelligence, civilization and a high technology. Also, we on the earth presently have all the technology vital for communicating with different civilizations in the depths of space. In fact, we may now be remaining on a threshold going to make the groundbreaking stride a planetary society takes however once: first contact with another civilization..
