Using the Hubble Space Telescope we have seen 13 billion light years into space, these are some of the very first galaxies to form after the big bang. [Search for "hubble space telescope ultra deep field images" to see the actual images.]

Although technology is always improving, we can never see much further than this point in time.

The problem is the time it takes for light to travel to Earth. The light we see from these very first galaxies have been travelling for 13 billion years to reach us, so really we are looking back in time. In them 13 billion years the light has been travelling to us, the universe has already expanded another 13 billion years. The reality is that many of the stars that make up these galaxies no longer exist in the same way we are seeing them today.

Theoretically, if the edge of the universe emitted visible light and stopped expanding today, we would still have to wait 13.7 billion years (the current age of the universe) before we would be able to notice. Therefore how far we can see is always governed by the time it takes for light to reach us.

If you think about it - the light we see from these very first galaxies was emitted before life and the Earth even existed! Bare in mind that light travels so fast it could go around the Earth 7 times in 1 second...

The Hubble telescope can see 13.7 billion light years away (pretty much the edge of the universe). But I have no idea how far you can see. Also, considering that the universe is expanding, everyday we can see a little bit further.

Telescopes have been aboard the spacecraft that have gone beyond the edge of the solar system. Zond, Phobos, Mars96, Mariner, Pioneer, Voyager, Galileo, and Cassini programs have sent many to all the planets except Pluto. And Pluto is no longer considered a planet. More craft have been sent to comets and asteroids.The farthest reaching ones are the two Voyager craft, that have gone far beyond Neptune. Each was carrying a fine telescope to image planets and moons during flybys.

How long is a piece of string? It depends on the strength of the telescope, check the box or the telescope it should have the magnification written on it. Also, you may not get this immediately, but any telescope picks up ONLY light that falls upon it, not matter how far away the object you are looking at. So telescopes really don't 'see' or 'detect' any distance at all. They just have varying abilities to focus and concentrate the light that comes to them.

The Hubble telescope cannot see the end of the universe but it can take photographs of distant nebulas, stars, etc. that are closer to the edge of the universe (and thus to its beginning) than earlier telescopes could.

Hubble can see somewhere in the neighborhood of 20 billion light years into space (knows as "the observable universe). That would be about 120,000,000,000,000,000,000,000 miles.

It's limit is 13.8 billion light years. THAT is pretty far!!!!!!!!!!!!

Well that depends. Like the Hubble can see 13.8 billion light years away, but smaller telescopes might not be able to see past the sun. Trick, huh?

Objects have been observed with distances estimated to be in the neighborhood of 13 billion light years.

n can see very clearly from space, as there are no clouds to block the view. About 900,000,000 miles can be seen.

People commonly look through telescopes to see into space. Telescopes are used by NASA to see stars and planets very far away, and less sophisticated models are used to see planets in our solar system, or even the moon.


Has the Voyager spacecraft left your solar system?

No. Both voyager 1 and 2 are on their way out of our solar system and will eventually escape one day. They have gone well beyond the furthest planet Neptune, but the solar system extends out much further, with the sun have a gravitational effect on objects as far out as 50,000 astronomical units or so. The voyager space craft has got out as far as 116 astronomical units so far.
