How can the antenna be so powerful, that we can communicate with that probe that is many light years apart, with no lost of signal?
i don't get it

NASA said so. :(

NASA said they sent humans on the moon in 1969.
"Why the live TV signal was so blurry? Can we have more proofs?"
NASA: "20 pictures aren't good enough! You idiots."

Yes but signal can be converted to digital with no quality loss. Because each peak is encoded...
So why do they keep using analog ? And pictures with resolution like my old VGA webcam?

With apparently telescopes that can see so far nebulas. How can they not be used to take high HD pics of near earth planets....

If I understand correctly, the answer would be that to view distant recesses of space the technology of radio telescopy is used...just light at various frequencies is analyzed. I don't think vigar has traveled a single light year as of yet...at a distance of about 10 billion miles it has traveled only a fraction of a light year which is about 6 trillion miles in distance.

Earthlike planets are discovered using an extrapolation of data...effects on observable objects such as parent stars.

Near Earth Objects are highly observable and very good photos have been taken, I think.
