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.
With at least 200 billion galaxies out there (and possibly even more), weâre very likely talking about a Universe filled with around 10 to the power of 24 planets , or, for those of you who like it written out, around 1,000,000,000,000,000,000,000,000 planets in our observable Universe.
