Can telescopes see 1000000 miles away?

Answer 1

Theoretically as far as infinity, it all depends on what one wants to observe. It also depends on how much distortion there is - atmosphere etc.

However, if a mountain is 50 feet from you and it is pitch black, then you cannot see it. If it is day light, then you can see it. Yet if that same mountain is a thousand miles away you may see it as a "feature" of the horizon.

The same with the universe. Some objects are so far away that there is "nothing" to "see" even if they exist.

If there was a star with a luminosity of 500 trillion times that of our Sun located 90 billion light years from Earth then there is a good chance we could observe it. If that same Sun had a luminosity of our own Sun then there is no chance we could observe it.

"See" relies on the ability to observe, based on luminosity and distance.

In fact, you can see the Milky Way with the naked eye. In certain directions, you see some clouds of light that span a large area of the sky.

Answer 3

A million miles away? Better start reading up. The Hubble Telescope can see 13.7 billion light-years out. Doing the math, that 13,700,000,000 light-years times 5,900,000,000 miles per light-year, or 80,830,000,000,000,000,000 miles, almost 81 quintillion miles.
