you gotta think of how long ago that picture was taken. It may have been recieved from earth in 1990. but the photo itself was taken probably a while back before then. You need to consider how far away the Voyager is. The signal transmitted back to earth can only be so fast. It probably took YEARS for earth to recieve that photo.

UGH! i cant even put into words how things beyond earth awe-strike me! i dont think anyone can
