Just 16 times larger than earth and orbiting in the habitable zone of a sun-like star, kepler-452b could be one of the best place in our galaxy so far to look for extraterrestrial life further investigation will require advanced, space-based telescopes such as those currently in development at nasa. The probability of humans finding extraterrestrial intelligence in our galaxy equals nfpnef1fifcfl, where n equals the number of stars in the milky way, fp equals the fraction of those stars having planets, ne equals the number of those planets that can support life, f1 equals the number of those planets on which life arises, fi equals the.

Ever since humans acknowledged the enormity of the universe, we have intuited that life must exist somewhere, either in our galaxy or some galaxy far, far away if the universe contains billions of galaxies, and if each galaxy contains billions of stars, and if a fraction of those stars have earth-like planets, then hundreds -- maybe even thousands -- of alien civilizations must exist across.
4 2001, more rigorous calculations connected to the 1960s drake equation suggests that our galaxy may contain hundreds of thousands of life-bearing planets. Using this approach, frank and sullivan calculate how unlikely advanced life must be if there has never been another example among the universe's ten billion trillion stars, or even among our own milky way galaxy's hundred billion. Does life exist elsewhere in the cosmos share attempting to estimate the number of life forms in our galaxy is a bit like guessing the number of words in a book.
