Planets capable of supporting life with fundamental needs are unexpectedly prevalent throughout the cosmos.It is estimated that there might be 60 billion planets in the Milky Way’s habitable zones suitable for life.With the huge quantity of galaxies, scientists predict around 50 sextillion habitable planets, suggesting Earth is just one possibility for supporting life.
