OBSERVABLE UNIVERSE IS 10 TIMES BIGGER THAN WE THOUGHT

There are at least two trillion galaxies — 10 times more than scientists thought — that exist within the observable universe. And we can’t even see most of them.

The unfathomable dimension and contents of our world never cease to amaze, and this year scientists showed you can never underestimate the universe.

Using the Hubble Space Telescope a group of international astronomers compiled 20 years of images from the observatory, and other international observatories, to create a 3D model of the 200 billion galaxies already

estimated to exist.

But the model instead revealed that there are at least one trillion eight hundred billion more out there. Only 10 per cent of these are visible to us even with our strongest telescopes.

“It boggles the mind that over 90 per cent of the galaxies in the universe have yet to be studied,” said Christopher Conselice, who led the study published in October in The Astrophysical journal.
