Are humans alone in the Milky Way? This constitutes one of the greatest astronomy investigations of all time. The Kepler mission was launched in March 2009 to scan a sector of the Milky Way to ascertain dozens of Earth-sized planets within the habitable zone (Jerry 1). Applying the transit method, NASA scientists would conclude that the amount of stars containing habitable planets has revitalized the question of extraterrestrial life. Through cutting-edge spacecraft and specially designed methods, NASA has achieved many of its key goals and discovered hundreds of exoplanets. Without a doubt, these discoveries have made Kepler one of the most important NASA missions to date. NASA formulated specific objectives for the Kepler mission. The aim is above all to delve deeper into the diversity and structure of planetary systems. This goal can be achieved by evaluating a large sample of stars. Through the Kepler mission, NASA scientists hope to achieve their 6 goals (Jerry 1). These goals include determining planets in the habitable zone and understanding the shapes and sizes of their orbits. Another goal of the Kepler mission is to evaluate the quantity of planets in multistar systems. Next, NASA hopes to evaluate the variety of sizes, densities and masses of short-period giant planets. Ultimately, these scientists and astronomers will determine more planets of each newly discovered planetary system and evaluate the characteristics of the stars that protect 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 through...... half of the document ......pler The mission had to continue until 2015 to achieve the set goals and objectives. On November 14, 2012, NASA announced the conclusion of Kepler's primary mission and the start of its extended mission. In February 2014, about a month ago, NASA (Van 1) announced the announcement of 715 newly verified exoplanets. In conclusion, the findings of the Kepler mission have raised questions in many different fields about the possibility of extraterrestrial life. As we understand our universe better, the future of astronomy begins to resemble science fiction. All things considered, the field of astronomy is getting closer to making further progress and perhaps finding an answer to this perplexing question. For now, Kepler's planetary candidates are under scrutiny. The results are exciting not only for science, but for human civilization.
