I am wondering if we could predict those events, and then launch a space probe similar to Voyager I and II that would be hooked in the alien star's gravity and orbiting around it while it travels in the Milky Way, which would be a some free speed for the space probe to explore space further.
Now, since stars rarely get that closed, I guess it's a bit pointless but I am still curious about it.
I wonder if another civilization had this same idea, and dropped a probe off some 70,000 years ago. Or perhaps the probe has yet to arrive, since elsewhere in this thread I see that comets dislodged by the perturbations of the passing stars are yet to arrive at Earth.
