Answer 2

The earliest estimates of the number of galaxies in the Universe were very small. For centuries, astronomers thought there might be just one—our own. Most recent estimates built off observations from 1995, when NASA’s Hubble Space Telescope stared at a dark patch of sky for hours and returned a picture of thousands of glittering galaxies no one had ever seen before. Further measurements led astronomers to believe there are between 100 billion and 200 billion galaxies in the observable Universe that human-made technology can detect. 
 
Galaxies — those vast collections of stars that populate our universe — are all over the place. Perhaps the most resonant example of this fact is the Hubble eXtreme Deep Field, a collection of photographs from the Hubble Space Telescope revealing thousands of galaxies in a single composite picture.
