Question:
What is the farthest object from the earth that has ever been detected? What is that distance of that object?


Replies:
Dear Kelly.,

The farthest object I have seen through my telescope is the double quasar Q0957+56 in Ursa Major. It is about 8.5 billion light years and is visible to us because it is gravitationally lensed by an intervening galaxy.

I believe the farthest galaxy was imaged by Richard Ellis, and it is about half a billion years younger than the big bang. If the big bang was 13.7 billion years ago, then the Ellis find is about 13 billion years. But that is somewhat uncertain.
