Answer:

No one really knows for sure, but there have been estimates that there are more than there are grains of sand. Hundreds of billions might be a reasonable "guesstimate".

  • Astronomers now estimate that the observable universe contains anywhere between 100 and 300 billion galaxies. However, if space time 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 their 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!
  • The answer to your question is unknown. The universe is infinite containing billions and billions of galaxies as it expands. Roughly 150-200 billion galaxies though.
  • It is not definite how many galaxies there are but there could be up to 500 billion galaxies! I think that was found out by a German organization.
  • There are millions of galaxies that we can observe from Earth, but there are millions more that we cannot observe.
  • About 100,000,000,000 (a hundred billion) and still expanding!
  • Let's not forget the galaxies that are not in the observable Universe! Add up all the galaxies in the entireUniverse (including the part we can't see) and the number of galaxies could be in the trillions or larger! Humans can't even conceive huge numbers like that so knowing this has little effect on most of us. It is truly mind boggling how many galaxies could be out there.

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.

There are no types of basic galaxies. There are galaxies of different nature such as spiral, barred spiral, lenticular and irregular galaxies.

Galaxy clusters typically have anywhere from 50 to 1,000 galaxies.

Spiral galaxies account for about 60% of all the galaxies. There are an estimated 100 billion galaxies in the observable Universe. So there about 60 billion spiral galaxies.

Approximately 60% of all galaxies are spiral

about 60 billion spiral galaxies

5 galaxies in each dome... 6 domes... 7 hidden galaxies... 3 trials... 70 galaxies.

Do you know how many galaxies are in space?It is never ending just like space.

Yes, galaxies frequently collide, our own milky way is a result of many galaxies colliding and merging.

There are Ten Billion Galaxies in outer space

125 billon galaxies exist :D

Yes, many galaxies rotate around a center or core. The majority of all of the known galaxies rotate around a core.

They study distant galaxies because they want to know whats out in other galaxies and how many planets it has

It's not known to any degree of accuracy, but about 66% of all spiral galaxies are barred and about 60% of galaxies in the local Universe are spiral galaxies.

There is no way to find out how many galaxies are documented, but according to the NASA Extragalactic database, there are 4 million named. It is estimated that there are hundreds of billions of galaxies in space.

All galaxies are massive clusters of stars scattered across the universe. Many galaxies take the same form, for instance, spiral and elliptical galaxies. Some galaxies also have a black hole in their center.

The milky way is the name of our galaxy, there are no other galaxies in it.

The group comprises more than 30 galaxies

It is believed that there are over 170 billion galaxies in the observable universe.

Yes, So many galaxies outside of our own.

There are no smaller galaxies in the Andromeda galaxy. In the Local group of galaxies to which Andromeda and the Milky Way are part of, there are around 30 smaller galaxies,

Not just dwarf galaxies. Giant elliptical galaxies lie likely the result of many galaxies, small and large, merging.

Elliptical galaxies are called so because of their peculiar shape. The number of stars in these galaxies may change galaxy to galaxy. So there is no saying how many stars.

A Galaxy Cluster can contain between 50 and a 1,000 galaxies.
