What did the Apollo 12 astronauts see — and was it really UFOs?

“Apollo 12 Commander Pete Conrad, Command Module Pilot Dick Gordon, and Lunar Module Pilot Alan Bean described 'streaks of lights' visible in the dark while trying to sleep. NASA later attributed the phenomenon to cosmic-ray flashes on the retina — internal to the astronauts' vision, not external objects.”

The Apollo 12 'streaks of lights' audio is catalog entry NASA-UAP-D008 in PURSUE Release 02 (UAP.WATCH ID AUD-001). The recording is a post-mission medical debriefing of Apollo 12's three astronauts — Commander Charles 'Pete' Conrad, Command Module Pilot Richard F. Gordon, and Lunar Module Pilot Alan L. Bean — describing instances of 'streaks of lights' visible in the dark as they tried to sleep during the November 1969 mission. NASA's medical team initially considered whether the phenomenon matched what Apollo 11 LM Pilot Buzz Aldrin had reported and whether retinal exposure to cosmic rays might explain it. NASA's final assessment, recorded in PURSUE: 'the phenomena reported by the Apollo 12 flight crew were internal to the astronauts' vision rather than external light sources' — galactic cosmic rays striking the retina at high speed.
