November 11, 2013 - 8.8 Billion “Goldilocks” Planets in Milky Way. “Just in our Milky Way galaxy alone, thats 8.8 billion throws of the biological dice.” - Geoff Marcy, Univ. of Calif.-Berkeley Of the estimated 200 billion stars in the Milky Way galaxy alone, scientists report that 40 billion of those stars are similar to our yellow sun. 1/5th of the yellow suns have Earth-size planets in the “Goldilocks” zone of temperatures that can sustain life. Further, reinforcing the likelihood of life elsewhere in our universe are recent German supercomputer simulations of data collected from the Hubble Space Telescope that estimate there might be as many as 500 billion galaxies in this universe, many older than the Milky Way Galaxy.
