How can some one see space objects which are millions of light years away? As I know, to see an object, we usually send light waves and capture the reflected ones back.

OK what I mean by this is I can stand at my back door step and see Mars at about 9:00 but how come I can’t see Mercury or Venus or anything else? Is it because the moon is blocking it?
Sorry if it doesnt make sence!!! =) please help me out.

Ok, so if the norther hemisphere sees one part of the universal sky, and the southern hemisphere sees the other, does the equator see all of the stars then? I’ve always been wondering. Thanks.
Fantasy Football Guru 27 asked:
How is it possible for scientists to have seen the gamma ray blast that supposedly occured 12.2 billion LIGHT YEARS away from earth. If im not mistaken, if something is 12.2 billion light years away from something, that means that at the speed of light, it would take 12.2 billion years to reach the object. How is seeing something that far way possible to see or detect?
