To misquote Carl Sagan...billions and billions. The deep sky survey has not been completed so no accurate count is given.

I have read that there are at least as many galaxies that we can see as there are stars in our milky way galaxy. This is estimated to be ~400,000,000,000. However, with the Hubble telescope it may be 4-5 times this amount or more. If our galaxy is average sized then that means ~800,000,000,000,000,000,000 stars are within our viewing ability. It kind of boggles the mind, doesn't it.

After the ultra deep field Hubble photo, I'm not sure that scientists can even guess. I heard that it could take decades just to get the count from the ultra deep view, and that was a very small portion of the sky.

The estimate that I have heard the most is 125 billion galaxies.

I don't know that there is an exact count - its in the billions (from the Hubble Deep Field Survey and other deep-sky surveys recently done).

There are probably more than one hundred billion galaxies in the universe.
