From LunaCognita, a handy overview of extraterrestrial strangeness:
This compilation includes many of my favorite NASA UFO encounters/sightings that I have archived over the years. All of these examples (with the exception of the second-to-last one) were captured on film by NASA astronauts or Russian Cosmonauts over the past half-century – showing many amazing examples from different eras – Gemini, Apollo, Apollo/Soyuz Test Project, Skylab, STS, the ISS, plus a couple Russian-source additions from their unmanned Zond and Mir Space Station programs as well thrown in to round things out.
