Voyager 2, which was launched before Voyager 1, but is traveling away from the solar system more slowly, has finally accomplished what its brother did in 2013 - leave the solar system altogether for interstellar space.

Technically, what Voyager 2 has done is leave the space that is dominated by solar particles and entered the space that is dominated by interstellar cosmic particles. This happens at a "border" of sorts called the heliopause, where the outward pressure of solar particles is no longer strong enough to beat back the interstellar particles.

Voyager 2 is actually the third most distant man-made object from the sun, behind not only Voyager 1, but also Pioneer 10. However, because Pioneer 10 is heading off in the opposite direction, it will take a lot longer for it to actually leave the solar system. Thanks to the sun's motion through the interstellar medium, the "border" between the solar system and interstellar space is not a sphere; it is greatly elongated in the direction the sun is traveling from. However, Voyager 2 is moving faster than Pioneer 10 relative to the sun, and is expected to pass it early next year. It will never catch Voyager 1, which is moving away from the solar system faster than any other object man has ever sent into space.

Interstellar space vs. solar system got me like...

Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there--on a mote of dust suspended in a sunbeam.

I've always enjoyed the thought that eons after the human species ceases to exist this song will still be floating in space.

"This is a present from a small, distant world, a token of our sounds, our science, our images, our music, our thoughts and our feelings. We are attempting to survive our time so we may live into yours."

Great. What if Voyager 1 kills the granddaughter of some super powerful being playing in her toy spaceship. Just what we need.
