Who knows. It's a bit like asking how old someone is who lives in New Mexico.
If we can see it and it's 13 billion light years away, then the only thing we know for
sure is that it existed 13 billion years ago. If the whole galaxy suddenly winks out
and disappears tomorrow, we won't know about it for another 13 billion years.
For that matter, maybe it already has!

It's very simple. A light-year is the distance light travels in one year, so what you see of a galaxy 13 billion light-years away, is as it was 13 billion years ago.

You'll have to live another 13 billions years to see it as it is "now"! :-)
What else can I help you with?
What was the year 13 years ago?
1998 considering the year is now 2011.
What was the climate 100 billion years ago?
I feel pretty confident in stating here that there was no climate to gauge if one takes into account that there was no 100 billion years ago, as it would've been before the big bang (13-15 billion yrs ago) which we now consider is when time began.
Why does the theme song from the big bang theory say 13 million years ago instead of 13 billion years ago?
The theme song of "The Big Bang Theory" refers to "13.7 billion years ago" in the context of the universe's age, but the line often gets simplified to "13 million years ago" in casual discussions. This is likely a misunderstanding or misquote, as the correct figure is indeed in the billions. The reference serves to highlight the vast timescale of cosmic history, underscoring the show's scientific themes through a catchy tune.
Is a redshift of 7 equal to a light travel distance of nearly 13 billion years?
Yes, a redshift of 7 does equal to a light travel distance of nearly 13 billion years (i.e. 12.9 billion years).
How many miles is 13 billion light years from earth?
No, that's the radius. The diameter is twice that, at about 27.4 billion light years. 13.7 billion light years is the furthest distance light can have travelled in our Universe which began, astronomers estimate, about 13.7 billion years ago.
When was the First year in time?
About 13 and a half billion years ago
When was the sun established?
Well over 4.6 billion years ago, but less than 13 billion years ago.
What was the year 13 years ago?
1998 considering the year is now 2011.
When did the universe form?
13 billion years ago because of the Big Bang.
The universe began about?
13-15 billion years ago through the big bang.
Estimate of when the Milky Way Galaxyfor formed?
maybe 13 billion years ago.
When did the first galaxies and stars develop?
About 13-14 billion years ago. Cosmologists are not in agreement as to what happened the first few million or billion years, but most agree that the age of our Universe is about 15 billion years.
Did the Milky Way Galaxy explode fourteen billion years?
Stars that now exist within our Milky Way -- indeed, all stars themselves -- did not exist till about 13 billion years ago. Our galaxy did not take its present form till about nine billion years ago.
What was the climate 100 billion years ago?
I feel pretty confident in stating here that there was no climate to gauge if one takes into account that there was no 100 billion years ago, as it would've been before the big bang (13-15 billion yrs ago) which we now consider is when time began.
How long will a star like earth's sun last?
13 billion years, roughly. Our sun was created about 6.5 billion years ago so it is just starting middle-age.
Can you explain me in simple words when will the world come to an end?
in about 13 billion years, that is the amount of time universe was created ago.
How many years ago did life begin in the Ocean?
3.5 billion years ago is the oldest direct evidence for life on Earth. Direct evidence is found in 3.5-billion-year-old cherts (rocks deposited in the ocean) in which several microorganisms have been identified. These microogranisms are much like cyanobacteria which is found in abundance throughout the Earth today. 3.8 billion years ago is the oldest indirect evidence for life on Earth. Indirect evidence is found in 3.8-billion-year-old banded iron deposits (chert) which contain a Carbon 13 to Carbon 14 ratios similar to ratios found in organisms today.
