Question

What is the farthest object from the Earth that we have detected?

Answer 1

Quasars. They have been detected at a redshift of z=6.7 (someone claimed they saw one at z=10 but that is disputed). They are the farthest objects. (Around about 1 mill. years after the universe formed). We think they are extremely bright AGN (active galactic nuclei) galaxies.

The cosmic microwave background (CMB, I've never heard it called MRB before...how fascinating!) isn't really an object as such, it is just radiation, but it is one of the oldest forms of radiation we can observe.

Answer 2

the ferthest thing ever dettecded was a galaxy called Abell 1835 IR1916 it is 13.23 billion light years away it is thought to be one of the first galaxys in the universe because we curently think the universe is about 14.7 bill years old we see how old it is by readshift and it is curently the ferthest thing away

but... ask this question again in 10 years and it will be a different      

anser because of the new space teloscopse going up soon lol

Answer 3

I think the farthest item would be the Microwave Background Radiation (MRB) observed by the Wilkinson Anisotropy probe.  It is probably the oldest observation we can ever observe , just after the Big Bang by about 380,000 years...the Universe is pretty much opaque before that.

Answer 4

Unfortunatly, by the time we can detect something far away, its actually nothing but a picture rays of some object, which was there billions of years ago. We don't know, whats out there.

Answer 5

The Oort Cloud which is about 1 light year away from the sun.  The Oort Cloud holds comets and defines the boundary of our solar system.

If you mean a specific, single object then it is definitely Sedna (see second link below).

EDIT:  Whoops...answered the question thinking in the earth's solar system.  My bad.

Most distant object ever detected is a galaxy 13 billion light years away (so looking back to a time when the Universe was about 700 million years old).  See last link below for more info.
