The Hubble Deep Field was an image taken by the Hubble Space Telescope over a period of about ten days, of a particularly dark patch of sky. If you looked in this area for a minute you would see nothing. Stray photons of light were captured and collected, and stacked and filtered, and the result revealed the light from thousands of distant galaxies. By measuring the number of degrees across the photo, and counting the galaxies, it became possible to estimate the number of galaxies in our universe.
There are about one hundred billion of them, or 100,000,000,000. That is a one followed by eleven zeroes, or 1 x 10^11 in scientific notation. Any way you say it, it is still a lot.
The universe contains countless galaxies, think of the universe as a galaxy of galaxies.

The galaxy, the one we are in, we call the Milky Way. It is one of billions of galaxies. These galaxies and everything else make up the universe. Compared to the universe galaxies are small fry.
Like our galaxy contains billions of stars, the universe contains billions of galaxies.
universe is largest. universe is made up of billions of galaxies.
Universe is describing the galaxies. There are different galaxies and our galaxy is called Milky Way Galaxy. There are some other galaxies miles away from ours.
The estimated number of galaxy mergers, given that there are 100 billion galaxies in the universe, is 100 billion.
A universe is a very big realm of darkness with galaxies in it. and there are billions of galaxies in the universe! One of those galaxies is our solar system, and in that solar system is our planet. There probably is even more then just one univserse. O_o Well... Galaxies are within the universe and a universe is defintly bigger then a galaxy
more galaxies
The estimated number of galaxy groups, given that there are 100 billion galaxies in the universe, is 100 to 200 billion.
Other galaxies are moving away because the universe is expanding, but we are not at the centre of the universe.
Yes. The Milky Way is just one galaxy. There are billions of galaxies in the known universe.
