Scientists: Universe contains at least 2 trillion galaxies
Astronomers say the universe contains at least 2 trillion galaxies, up to 20 times more than previously thought.
The finding was not easy to come by. An international team of scientists examined deep space images taken by the Hubble Space Telescope from over the past 20 years and converted them into 3D pictures.
From there, they measured the number of galaxies at different times in the history of the universe.
The researchers also used new mathematical models which allowed them to infer the existence of galaxies which the current generation of telescopes cannot observe.
This led to the surprising realization that some 90 percent of the galaxies in the observable universe are actually too faint and too far away to be seen yet.
Past observations had estimated the number to be around 100 billion.
