Q&A: Galaxies, Galaxy Clusters, AGN, and Quasars
What is the most distant object Chandra can see, and what type
of object is it?
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.
