I know, it's the way they always say it just 1000 light years away, as if anyone alive in the next 1000 years at least is going to live to see it.

That depends entirely on what fraction of c one is traveling and what reference frame you're using.

Counterintuitively, travelling 1000ly at 0.99c won't take anywhere near 1000 years for the passengers.

....not that it's even possible today.
