I WONDER - Where Have Space Probes Travelled?

Probes have ventured beyond our solar system into interstellar space. NASA's Voyager One and Two, initially launched in the 1970s to study outer planets, have traveled farther than any human-made objects. They carry golden records with Earth's sounds and images, intended for potential intelligent life. Pioneer 10, 11, and New Horizons also transport human artifacts beyond the solar system.

How far have the Voyager probes traveled compared to other human-made objects?

What is the significance of the probes carrying sounds and images from Earth?
