Best Answer

Astronomers now estimate that the observable universe contains anywhere between 100 and 300 billion galaxies. However, if spacetime is flat on large scales (as it seems to be), the universe is infinite in size and contains an infinite number of galaxies in total - they are just so far away that there light has not had time to reach us since the beginning of the universe. In fact, because the universe is expanding, we will never see most of these galaxies ever!
billions
The answer to your question is unknown. The universe is infinite containing billions and billions of galaxies as it expands.

Scientist's have estimated about 125 Billion galaxies or even more.
There must be approximately 1011 galaxies in the observable Universe.

Note 1: That's a 1, followed by 11 zeroes.

Note 2: The entire Universe is probably much bigger, but it isn't know how much.

There is no definitive answer.

Every time we develop better telescopes, we discover that what we thought were tiny smudges on the photos were actually more distant galaxies. Astronomer Carl Sagan was sometimes mocked because of the way that he used to pronounce "BIL-lions and BIL-lions of stars", but it turns out that he was wrong; he should have said "Billions _OF_ billions".

There are probably more than 100 billion (1011) galaxies in the observable universe at distances up to 13 billion light years. That's only in the observable Universe, the part we can actually see. There are probably hundreds of billions more galaxies out there! We will never find them all.

There are billions of galaxies.

New ones are forming constantly.

Existing ones merge and separate forming others.

Who knows!! New stars are being found almost daily.

Our Galaxy contains anywhere between 100 and 400 billions stars, and it's estimated that there are upwards of a 100 billion galaxys

So estimating, there are over 10,000,000,000,000,000,000,000

far over 200 billion.

if you saw 1000 differrent galaxies every night it would take 275,000 YEARS to find them all. and there are more continously made as the universe expands.

In which direction are mostly all galaxies moving?

Actually, most galaxies are all moving away from all other galaxies, not just from ours. The exception is the Andromeda galaxy, with which the Milky Way is on a collision course.


What determines the shape of a galaxy?

That is related to their past history. Many galaxies have undergone collisions with other galaxies; this takes out most of the interstellar gas, and the galaxies can no longer form new stars. If I remember correctly, such galaxies will change into elliptical galaxies.That is related to their past history.

Are all 100000000000 galaxies in our universe be any size and shape?

Yes, galaxies can be any size and shape.


What is tough to be at the very center of all galaxies?

Perhaps you mean "thought to be"? - It is believed that all, or most, galaxies have a supermassive black hole at their center.


Three quarters of all known galaxies are what galaxies?

That is a difficult question to fully answer as types of galaxies are not fully defined. A ball park figure would be dwarf galaxies, or spiral galaxies depending on the area in question. See related question for a full breakdown.

How many stars are in a cluster?

A cluster is a collection of galaxies, normally less than about 50 galaxies. All clusters are different and all galaxies are different. A ball point figure would put the maximum number of stars at around 10,000,000,000,000 stars or 10 trillion.
