Unmanned spaceprobe Voyager 2, launched in August 1977, has flown out of the Solar System and into interstellar space. That happened on 5 November 2018.

The coolest thing is that the Voyager probes carry grammophone records with a taste of Earth, if some extraterrestrials find them.

That's incredible. And I'm amazed that a launch 16 days apart, plus different trajectory, resulted in a 6 year difference. I didn't even exist when this thing and its sibling left Earth... With that distance and age of the technology, wonder how long it takes for a signal to come back.

I guess if the solar system is somewhat disc shaped, if we just went in the direction we label as "up," rather than out past the planets, I suppose we'd leave the solar system a lot sooner...?

Not long, a lot of people don't realise that the transmissions from both are actually as light (most probes are this way), so less than a day even at the distances they are at.

I love the optimism on the part of the ones who launched it, that the alien space travelers who may come across it would have a record player. :lol:

At least they had the good sense even then not to pack it with 8-tracks. Human beings don't even know what those are for anymore, let alone space people. :trazz:

I'm genuinely curious which records were included. Hopefully, nothing by the Grateful Dead. That'd most likely be considered an act of war, even way up there.

I read.. just various noises that are 'found' on our Planet Earth.
That is what is on the copies of The Golden Discs that are on-board both Voyager 1 and Voyager 2.

I think there should be some Elvis Presley, Beatles and Dolly Parton.
