So scientists say that there are billions of stars. But how far away from earth have they detected this? How far can we see into the sky? Does it seem like a neverending sky of stars?

We can only see as far as the lights/radiation of the stars reach us. Beyond that we simply 'don't know'.
What we currently know about the Universe is Next to Nothing!

Actually we "see" into the past when we look into the stars. Even as we just stratched the surface of space technology... there is far more information to glean on how far we can can see... we know that the stars are suns with their solar systems... in between each universe... well, is a void. To breach that void... the explanations to our answers will fulfilled... but for now... we can wonder.

Our universe does not go on forever. There is an "edge" so to speak. The universe is a big, growing bubble. The edge is expanding at the speed of light, so we would have to be going very fast (actually, so fast that we would be going backwards in time) to catch up to the edge. If you were able to catch up to the edge, the universe would appear much smaller and brighter. If you got to the edge, you would see the big bang, so you really couldn't cross the edge, at least using current physics. Beyond the "edge" is the multiverse, but that's difficult to explain.
Current technology that a majority of humans are privy to anyway, does not enable superluminal travel (i.e."warp" speed), so you can, at best, possibly make it to other star systems nearby using primitave chemical rockets.
For humans to explore space -deep space, that is- they are going to need to understand and be able to manipulate gravity. Also, more research is going to be needed in a new line of physics (something that better considers quantum physics with universal/expansionary physics I suspect). Humans will also have to learn to get along a little better with everyone too.
Anyway, the universe is big and it is interesting.

The stars we can see are in a range of the limits of our galaxy. after that we can see the galaxies like small stars.
Several satelites that are in orbit around the earth give us some info about the universe which for the moments its boundaries are approx 13.5 billion light years away and constantly expanting.

Theoritically, space has no boundaries.
