If some of the galaxies in this image are 10 billion light years away what does that mean you are actually looking at when you take a picture of those galaxies?

You are looking at the light that that star made 10 billion years ago. Since it takes that many years for the light to reach earth, you would not notice if that star died for 10 billion years, just like you wouldn't notice by looking at it that the sun suddenly died for 8 minutes (The amount of time it takes for its light to reach the earth). We are constantly looking at the sun 8 minutes ago!

Can two galaxies combine together?
Galaxies do combine or merge together. In about 4.5 -> 5.5 billion years time time, the Andromeda Galaxy will combine with our galaxy, the Milky Way Galaxy. In a lot of cases Irregular Galaxies are believed to have formed with interactions with other galaxies. See related link for a picture of two galaxies merging.
What other types of galaxies are there besides the milky way?
The answer is YES. There are an estimated 200 billion galaxies in the known Universe. Most of these galaxies are relatively similar to our own, some bigger, some smaller, some differently shaped. Most galaxies hold 50-200 billion stars, and average about 50,000 - 100,000 light years across. Light travels at 180,000 miles PER SECOND, so if it only takes 2 seconds to get to the moon, 30 seconds to Mars, but 100,000 light years to cross our own galaxy, imagine the size! Mind boggling!
What is the shape of the black eye galaxy?
The Spindle Galaxy (NGC 5866) is a relatively bright lenticular galaxy in the constellation Draco.It is about 50 million light years from us.See related link for a picture.
How far would you travel to get from earth to mercury?
Well when looking at it on the picture that I have right in front of me, I'd say a few milliseconds.
Is it possible to find the absolute location or relative location of North America using a flat picture map?
No, because there are no lines of latitude or longitude on a picture map. It would be hard to figure out where a city actually is without them.
Will the Hubble Space Telescope capture an image of 100 billion galaxies in the universe into one picture?
The Hubble Space Telescope is a space telescope that was carried into orbit by a Space Shuttle in 1990 and remains in operation. Although it has taken photos from other galaxies, it does not have the capability of capturing a single image of 100 billion galaxies on one photo.

What is the furtherest distance scientists have been able to see into the universe?
The answer is quite more complicated than it seems. The farthest astronomers have seen in the visual spectrum is the Hubble Ultra Deep Field. This picture looks back in time about 13 billion years, and the galaxies it has captured wereprobably no more than 800 million years old. But it is a common misconception that since light travels at a set speed, a picture looking back 13 billion light years must be a picture of something 13 billion light years away. This isn't the case. Since the universe is constantly expanding, the galaxies depicted in the HUDF picture are no longer 13 billion light years away. In reality, the universe is now about 90-140 billion light years across. It comes off as a paradox because the universe technically expanded faster than the speed of light (how else could light from galaxies now 90 billion light years away reach us in 13 billion years?) It's a strange consequence of general and special relativity. Put simply, the light from the farthest objects scientists can see originated 13 billion light years ago, but these objects are not that far away in real time.
