One solution often used in science fiction is to place the space travelers into suspended animation, typically in a state of biological suspension akin to a deep sleep.

It turns out that Tabby’s Star — the star that has been hypothesized to have an alien megastructure around it — is not alone when it comes to wild fluctuations in its light output. Astronomers at Germany’s Max Planck Institute for Extraterrestrial Physics have found yet another star that experiences its own drops in brightness, although this one may offer a clue as to why it appears to periodically flicker out.
