"Stars are not spread uniformly across the universe, but are normally 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 (1011) galaxies in the observable universe.[39] While it is often believed that stars only exist within galaxies, intergalactic stars have been discovered.[40]
Astronomers estimate that there are at least 70 sextillion (7×1022) stars in the observable universe.[41] That is 230 billion times as many as the 300 billion in the Milky Way."
