Unidentified flying objects have been reported by astronauts while in space. These sightings have been claimed as evidence for extraterrestrial life by ufologists.

Some of the alleged sightings never occurred: science fiction writer Otto Binder perpetuated a hoax claiming Apollo 11 Commander Neil Armstrong had encountered UFOs during the Apollo mission.^[1] UFO proponents see comments by astronauts or photos processed by NASA as one of the "strongest bodies of evidence" because they are considered to be of high trustworthiness; however, NASA Assistant Administrator for Legislative Affairs, Robert F. Allnut, concluded in a 1970 letter, "after fifteen years of manned space voyages including space stations and landing on the Moon, spacemen have brought back not a shred of evidence – verbal, photographic, or otherwise – for the existence of extraterrestrial spacecraft, or 'UFOs'."^[2]

In 2009, footage from NASA was posted on YouTube by ufologists which "renew[ed] UFO conspiracy theories that the government is hiding knowledge about its interactions with intelligent life" by relying on a "lack of context" to promote a "collection of indistinct imagery and allegations".^[3] A number of the incidents were collected for an episode of the 2014 television series Are We Alone?.^[4]
