How many galaxies are there in all?

Answer 1

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.

Answer 2

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.

Answer 3

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".

Answer 4

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.

Answer 5

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.

Answer 6

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

Answer 7

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.

Answer 8

There are estimated to be around 100 to 200 billion galaxies in the observable universe. Each galaxy can contain billions to trillions of stars.

Answer 9

hundreds of billions
