Too many to count, unless you were seriously bored.

The universe is made up of many galaxies. When galaxies were first discovered they were called island universes because they looked like islands of stars in a dark sea. New galaxies are discovered every day containing large numbers of stars. My results show the number of galaxies from some sources is the same and from some it is different. The more recent sources give larger numbers. This is because of new inventions that make it easier to find galaxies. One of these is the Hubble Space Telescope which enables us to see farther out into space and locate more of the universe's galaxies. These sources are just estimates because the numbers are always changing. Another reason that we do not know the exact number of galaxies is because they range in sizes. There can be extremely large galaxies and extremely small galaxies. The smaller galaxies are harder to detect.
I did a galaxy search here at work ..
according to our observatory's massive database the number of galaxies entered in the system is
125 billion galaxies
As they are discovered they are immediatly faxed to us so that is the number of galaxies as of this post .

Billions upon billions. Honesetly no one knows. The amazing thing is that every galaxy can contain billions of stars... It's almost unimaginable. Check out this cool picture...

almost every dot in the picture is a galaxy containing billions of stars each. If anything, this picture will help you realize how small a part our little planet is in the universe. Sorry it is kind of low quality... but here are some more for you:

Billions upon billions. There's a picture my science teacher showed us that was separated into 1 in.sections. In every square inch, there was more than a million galaxies.

Carl Segan says Billions and Billions.
