With the Voyager II spacecraft millions of miles from earth and continuing on, how are we able to send/receive data from deep space?

Even though there’s some good answers here, I think people are failing to address something – the messages sent to and fro travel at *almost the speed of light*! So even if Voyager 2 was 300,000 km away, it would still only take 1 second for its messages to reach us, and another second for our messages to reach it. This can reasonably go on for YEARS!
