There are roughly 500 billion galaxies in the universe, meaning there is somewhere in the region of 50,000,000,000,000,000,000,000 (5Ã1022) habitable planets. Iâll leave you to do the math on whether one of those 50 sextillion planets has the right conditions for nurturing alien life or not.
There are an estimated 100-300 billion galaxies in the observable universe. The number of stars in a galaxy depends on its size. The Milky Way Galaxy has between 200 and 400 billion stars.
