NASA pointed the Hubble Space Telescope at a very dark section of sky to see what might be found. The telescope revealed
about 10,000 distant and never-before-seen galaxies. NASA would have to make observations of more than 10,000,000
other sections to study the rest of the sky. If every section of sky also looked out on 10,000 galaxies, about how many
galaxies would exist in the known universe?
100,000,000
1,000,000,000
10,000,000,000
100,000,000,000
