Matter Content
The observable universe contains between 1022 and 1024 stars (between 10 sextillion and 1 septillion stars). To be slightly more precise, according to the Sloan Digital Sky Survey, " a conservative estimate.... the currently observable universe is home to of order 6 x 1022 stars" These stars are organized in more than 80 billion galaxies, which themselves form clusters and superclusters.
Two approximate calculations give the number of atoms in the observable universe to be close to 1080.
