Q&A: Chandra Mission
Q:
What is the most distant object Chandra can see, and what type
of object is it?
A:
The most distant objects detected by Chandra so far are quasars.
The X-rays we see from these objects left the objects about 13
billion years ago, when then age of the universe was a little
over a billion years, and was about one-sixth of its present
size.
