how many galaxies are there in the universe
If you assume that the XDF is a typical region of outer space, you can calculate how many XDFs it would take to fill the entire night sky; itâs about 32 million. Multiply by the number of galaxies you find in the XDFâwhich is around 5,500âand thatâs how we arrive at 176 billion galaxies, at least, in the Universe.
