Trillions of Galaxies in Universe
The Milky Way Galaxy is our cosmic home, but we are definitely not alone in the observable universe. With the help of the revolutionary Hubble telescope, astronomers took their first deep look at the universe in 1995 and revealed a mind-blowing estimate of 120 billion galaxies. With the advanced technology of the Hubble and other telescopes, a new analysis of deep space has led astronomers to revise that estimate 10 fold into the trillions, since 90 percent of the galaxies in the universe are too faint and too far away for the current generation of telescopes to observe.
