Ten superclusters.
The estimated number of satellite galaxies, given that there are 100 billion galaxies in the universe, is 170 billion.
The estimated number of galaxy mergers, given that there are 100 billion galaxies in the universe, is 100 billion.
The estimated number of galaxy groups, given that there are 100 billion galaxies in the universe, is 100 to 200 billion.
There are approximately 7 trillion dwarf galaxies in the universe.
There are at least 15 billion elliptical galaxies in the observable universe, at distances up to 13 billion light years.
There are at least 5 billion irregular galaxies in the observable universe, at distances up to 13 billion light years.
There are at least 20 billion lenticular galaxies in the observable universe, at distances up to 13 billion light years.
There are an estimated 1011 (100 billion) galaxies in the observable Universe. It is not known how much bigger the Universe is, compared to the observable part.
Yes. Looking at a deeps space image it is apparent that the universe is filled with Galaxies. It is estimated that there are about 200 billion galaxies in the observable universe.
The observable Universe is estimated to have around 1011 (a hundred billion) galaxies. The entire Universe is much bigger than that, but it isn't known how much bigger. Perhaps it is infinite, in which case it might have an infinite number of galaxies.
If you counted 1 galaxy per second, it would take ~3200 years to count all 100 billion galaxies in the universe.
Yes. There is an estimated 1011 (a hundred billion) galaxies in the observable Universe.
