Well, if the universe is expanding, as many believe, then the answer to that question changes all the time. :) this would mean that space would never end because it never stops expanding
Here are some interesting things to read about it though:

well space is probably lasting forever, or if people believe that its expanding from it's small are. that's fine
Depending on the direction observed, the visible universe is tens of billions of light-years in radius. Just the observed part appears to contain billions of galaxies. But the images we see of some distant stars are the light that left them before the Earth existed.
The only universe we know is many billions of light years in circumference.
The universe is ever expanding at a very quick rate. The currently most quoted estimate of the minimum radius of the observable universe is 78 million light years, that is a diameter of 156 million. Whether the universe as a whole is spatially infinite is not known, though that assumption is consistent with observations.
Although we may make presumption, the true answer is not known yet, we will leave it to future scientists.
im telling you know space is never ending!!!!!!
infininte... it just keeps going and going, in fact, scientists have discovered that indeed, the universe is getting bigger. That's only in our solar system. there are probably millions of different solar systems out there.
That would basically be the size of the Universe. This is not currently known. The observable Universe has a radius of about 46 billion light-years; the entire Universe is probably much larger than that.
The known visible Universe is approximately 100 billion Light Years across. However that does not mean it is not bigger it just means, that that is as far as we can see at the moment. 50 years ago we would not have been able to see that far. There are many theories as to how large the Universe is, but what is measurable with toady's technology is as I stated before, about 100 billion light years spherical across.
Space is ever expanding with not only many galaxies but multiple universes that even at the current moment may be in the process of creation right now. Space can never be measured.

The observable Universe has a diameter of about 90 billion light-years. It is believed that the Universe stretches out much further - but how much further is not currently known, not even approximately.
our space to be at least a billion trillion
(10^21 ) times bigger than the largest distances our hunter-gatherer ancestors knew about
There is an ending spot in space. It's just a forever place. Eternity!
Approximately 18,000 mph.
The space shuttle takes approximately 1 month to reach space.
The Kennedy Space Center complex encompasses approximately 219 square miles of area on the Florida Space Coast. That doesn't include the adjacent Cape Canaveral Air Force Station across the Merritt Island Causeway, which comprises about 1,325 acres.
The Space Shuttle Endeavour, the orbiter built to replace the Space Shuttle Challenger, cost approximately $1.7 billion.
Approximately $40 billion
The Big Bang is believed to have occurred approximately 13.8 billion years ago, making it the earliest event in time that we know of.
Approximately 18,000 mph.
Quite big!!!
It is approximately a sphere.

That is approximately 355 ml. of space

Space Is Infinatly Big
Most theorists will tell you that there was no space at all before the 'big bang'. Space itself began expanding along with the materials in the big bang.
BIG VERY BIG!!!!
Really big.
