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; itâs about 32 million. Multiply by the number of galaxies you find in the XDFâwhich is around 5,500âand thatâs how we arrive at 176 billion galaxies, at least, in the Universe.
Livio pointed out there could be galaxies in these other universes â if they exist â but we have no way right now of knowing for sure. So the number of galaxies could even be greater than 200 billion, when considering other universes. In our own cosmos, Livio said, astronomers will be better able to refine the number upon the launch of the James Webb Space Telescope (for which his institute will manage the mission operations and science).
