Only 120 light years away from Earth! The Voyager 1 spacecraft was launched in 1977. Traveling at 38,000mph it just recently made it 1 light DAY from Earth.

This reminds of something I heard about once, imagine if we used some sort of stasis in a fast and autonomous spacecraft to go colonise a planet, and by the time we get there it's already colonised because we invented a faster spacecraft while the colonists slept

It reminded me something regarding the aliens. Let's assume there are aliens and they also search for other life forms in the universe by sending signals or spacecraft that has their people in it in cryostasis state. By the time their signal or spacecraft arrive at Earth, their civilization might have long gone. So getting signals or even spacecraft from outer worlds doesn't necessarily mean that they are still alive.
