How many galaxies are there in the universe?

In 2015 it was believed that the observable universe contains 100-200 billion galaxies; in October of 2016, some new applications of mathematical modeling to the Hubble deep-space images produced a new estimate of 1 trillion to 2 trillion galaxies

Until a couple of weeks ago, the established count for galaxies was about 200 billion galaxies.

170 billion according to Wolfram Alpha.

But that may already be out of date, as last year a study stated that there are more than 10x more galaxies than previously thought. Nearly 2 trillion of them in the observable universe!

It's estimated to be somewhere between 100 and 200 *billion*....

Over 1,000 ......Ours has over 1 , 000 stars itself !..... Imagine over 1,000 galaxies with over 1,000 stars each !

No one knows. If you look in any direction in an area of sky the size of a dime held at arm's length, you'll see tens of thousands of galaxies. James Webb will use infrared, and will be able to see 1,000 times further. So I imagine we'll be seeing the very first galaxies within the next year or two. But to answer your question, there's no way to make an accurate guesstimation. There could very well be trillions in the observable universe.

Trillions.

all of them

According to the best estimates of astronomers there are at least one hundred billion galaxies in the observable universe. They've counted the galaxies in a particular region, and multiplied this up to estimate the number for the whole universe.

It's unknown to me.

Lots. Any other answer is pure speculation.

At least 400 billion, but perhaps more. We haven't really looked everywhere.
