The Universe May Have 10 Times As Many Galaxies As We Thought

Previous estimates suggested the existence of 100 billion to 200 billion galaxies, but apparently that data was way off, since new findings allege that the number has to be closer to a trillion based on how things are behaving in space. "آ…it boggles the mind that over 90 percent of the galaxies in the cosmos have yet to be studied."

آ…astronomers used all available data to construct a 3-D map of the universe around us, which allowed them to chart the number of galaxies that existed at different periods in history آ— the farther away a telescope looks, the further back in time it looks, because we're seeing light that has had to travel longer distances to reach the lens. The team's mathematical models indicate that for the universe to behave as it does, there must be more than a trillion galaxies unaccounted for. Their results are set to be published soon in the Astrophysical Journal.
