Are human beings alone in the Milky Way? This is one of the largest astronomical surveys of all time. The Kepler mission was launched in March 2009 to scan a sector of the Milky Way for dozens of Earth-sized planets in the habitable zone (Jerry 1). By applying the transit method, NASA scientists would conclude how many stars contained habitable planets, which revitalized the question of extraterrestrial life. Using advanced spacecraft and specially designed methods, NASA has achieved many of its fundamental goals and discovered hundreds of exoplanets. Unquestionably, these discoveries made Kepler one of NASA's most remarkable missions to date. NASA has formulated specific goals for the Kepler mission. Above all, it is a question of deepening the diversity and structure of planetary systems. This goal can be achieved by evaluating a large sample of stars. Thanks to the Kepler mission, NASA scientists hope to achieve their 6 objectives (Jerry 1). These goals include determining which planets are in the habitable zone and determining the shapes and sizes of their orbits. Another goal of the Kepler mission is to assess the number of planets in multiple star systems. Next, NASA hopes to assess the variety of sizes, densities and masses of short-period giant planets. Finally, these scientists and astronomers will determine more planets from each newly discovered planetary system and evaluate the characteristics of the stars that host the planetary systems. These goals are what Kepler mission employees strive to achieve every day of the mission. The Kepler mission is the first to be able to detect Earth-sized planets around other stars. This is possible in the middle of the document......pler The mission was to continue until 2015 to achieve the goals and objectives. On November 14, 2012, NASA announced the conclusion of Kepler's primary mission and the start of the extended mission. In February 2014, about a month ago, NASA (Van 1) announced the discovery of 715 newly verified exoplanets. In conclusion, the Kepler mission's findings have raised questions in many areas about the possibility of extraterrestrial life. As we understand more about our universe, the future of astronomy is starting to look like science fiction. All things considered, the field of astronomy is poised to make even more progress and possibly find an answer to this puzzling question. For now, Kepler's planetary candidates are being examined. The results are exciting not only for science, but also for human civilization..
