How Cosmic Rays Make Astronauts See Stars

Cosmic rays, high-energy particles from space, affect astronauts by causing visual phenomena and potential health risks like cancer and cataracts. Earth's magnetic field offers some protection, but regions like the South Atlantic Anomaly expose spacecraft to radiation. Research aims to understand and mitigate these effects, with theories like Cherenkov radiation and retina interaction being explored. Protecting astronauts from cosmic radiation is crucial for future space exploration.
