"Stars are not spread uniformly across the universe, but are
usually grouped into galaxies along with interstellar gas and dust. A typical galaxy contains hundreds of billions of stars, and there are more than 100 billion galaxies in the observable universe. While it is often believed that stars only exist within galaxies, intergalactic stars have been discovered. Astronomers estimate that there are at least 70 sextillion (7×1022) stars in the observable universe. [Wikipedia].
But didn't God already say that?
"As the host of heaven cannot be counted and the sand of the sea cannot be measured,..." (Jeremiah 33:22 NASB)." IPS
