The furthest object we have observed, is a destructing star (GRB 090423) at 13.1 billion light years away.
This answer is only partially correct because humans can only see that distance with improvements on their eyes. For example a telescope. But humans originally can only see 2,300,000 to 12,000,000 light years into space with perfect vision & nothing to enhance their sight.
Not even close to a million light years away, at least the ones we can see. All the stars we see in the sky are in our own galaxy, the Milky Way, which is 100,000 light years across. Most of the stars that are visible to the naked eye are less than 1,000 light years away. Sirius, the brightest star in the night sky is 8.6 light years away. There are stars millions to billions of miles away in other galaxies, but we cannot see them at such a great distance. Even with telescopes it is difficult to make out individual stars.

When you see a galaxy 8 billion light years away you are how many years into the past?
When you see a galaxy that is 8 billion light years away, you are observing it as it was 8 billion years ago because light takes time to travel across such vast distances.
How many light years away is warped galaxy?
ESO 510-G13 is a spiral galaxy approximately 150 million light-years away in the constellation Hydra See:- http://en.wikipedia.org/wiki/File:Warped_galaxy.jpg
How long would it take to see a star explode on earth?
That depends on how far away the star is. If the exploding star is 1,000 light years away we would see the supernova 1,000 years later. If it is 2,000 light years away we would see it 2,000 years later.
If you had a telescope on a planet 3000 light years away and zoomed in on earth what would you see?
If you had a telescope on a planet 3000 light years away and zoomed in on Earth, you would see the Earth as it was 3000 years ago. Due to the time it takes for light to travel, you would not be seeing Earth in real-time, but rather how it appeared 3000 years in the past.
If you look far enough away can you see Earth in the past?
No. If you look far enough away, you will see OTHER objects in the past. For example, if a galaxy is ten million light-years away, the light of this galaxy took 10 million years to reach us, so we see this galaxy 10 million years ago. Earth's light, from millions of years ago, doesn't come back to us, since (roughly speaking) light travels in a straight line, and moves at the speed of light (300,000 km/sec).
How many light years are there in stars that are in your sky?
The distance to stars is measured in light years, which is the distance light travels in one year. The stars we see in the night sky are typically several light years away, with the closest star to Earth, Proxima Centauri, about 4.24 light years away.
With the worlds largest telescope you can only see how many billion light years away?

When you see a galaxy 8 billion light years away you are how many years into the past?
When you see a galaxy that is 8 billion light years away, you are observing it as it was 8 billion years ago because light takes time to travel across such vast distances.

How can you see stars billions of light years away?
The light from the stars travels billions of years. Most of the stars we see are already gone, but the light from them us still traveling.
How long would it take to see a star explode on earth?
That depends on how far away the star is. If the exploding star is 1,000 light years away we would see the supernova 1,000 years later. If it is 2,000 light years away we would see it 2,000 years later.
The star is about 425 light years away if it explodes tonight?
You will see it in 425 years time
What is the distance of the stars you see at night?
If you mean, with the naked eye: anywhere between 4 light-years, and thousands of light-years; however, there are three galaxies you can see with the naked eye, two of which are about 180,000 light-years away, while the Andromeda Galaxy is 2-3 million light-years away. With powerful telescopes, on the other hand, stars and galaxies can be seen that are millions, and even billions, of light-years away.
How many light years out can your telescopes look out in space?
With the naked eye, you can see stars up to about 1000 light years away. You can also see the Andromeda Galaxy. That's about 2.5 million light years away. That's the most distant object visible to the naked eye. Binoculars show it easily. With a 3" refracting telescope can see stars down to at least magnitude 9, plus some galaxies beyond Andromeda. The biggest telescopes can see to over 10 billion light years.
If you had a telescope on a planet 3000 light years away and zoomed in on earth what would you see?
If you had a telescope on a planet 3000 light years away and zoomed in on Earth, you would see the Earth as it was 3000 years ago. Due to the time it takes for light to travel, you would not be seeing Earth in real-time, but rather how it appeared 3000 years in the past.
Why can you see 2500 light years away but cannot get a good picture of Pluto?
Well yes there is light on Pluto. But it is very very hard to see. The objects we see that are 2500 light years away are unimaginably gigantic. In comparison, Pluto isn't even the equivalent of a tiny particle of dust.
How many years does starlight travel?
It depends on the distance of the star to Earth. The distance to the star in light years is the number of years the light took to get here. Most of the stars we see at night are within a few hundred light years of Earth. The closest star other than the sun is about 4.2 light years away.
