Based on the most recent information, astronomers estimate that there are not just billions of other galaxies, but trillions of galaxies. Many, like our Milky Way, would be made up of 100-400 billion stars each. Some think there could be as many stars in our universe as there are grains of sand on the earth. At the time of this writing the largest known galaxy, “IC 1101,” is approximately one billion light years away and is thought to have trillions (not just billions) of stars. Some astronomers once directed the Hubble Telescope at what looked like a tiny black speck in space, about the size of a grain of sand held at arm ’s length . Then they took a twelve-day [1,000,000 second] time exposure of that speck. When they enlarged the photo of that speck what do you think they saw? — Galaxies, galaxies, and more galaxies!
