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.
How far can a signal from Earth be received and be understandable?
In other words, can signals be sent from Earth and be receivable by far-away sources like other star systems? We can ‘barely’ hear Voyager 2, not even a light year away but it’s an extremely weak signal.
