NASA, the United States' space agency, is dedicated to space exploration and both crewed and robotic missions.
Documentation from astronauts who have observed lights and particles in space offers a glimpse into how such sightings were recorded and investigated during various missions. A sighting that isn't immediately identified isn't proof of aliens. Among the explanations discussed in NASA's documentation are intraocular phenomena, water droplets, and particles near the spacecraft; there are also cases where the available material doesn't allow for a definitive determination of what was seen. Here you'll find articles, photographs, transcripts, and interviews related to NASA and UFOs.

Common questions about NASA
What is NASA?
NASA is the United States' space agency. It is involved in space exploration, crewed and robotic flight programs, and scientific research.
Has NASA confirmed the existence of aliens?
The materials presented on this page do not prove alien visitation. Unidentified sightings or those unexplained by the available documentation are not, in themselves, evidence of an extraterrestrial origin.
What have NASA astronauts seen in space?
The documentation and articles on this page describe flashing lights, sparkling particles, and objects seen near spacecraft or against the backdrop of Earth. In some cases, explanations have been offered, while in others, the available information is insufficient for identification.
Did the flashes seen by astronauts come from aliens?
Not according to the information described here: NASA determined in the case of the Apollo 12 crew that the flashes did not come from outside, and other articles discuss the possibility that their source was an intraocular phenomenon. No report of a flash should be automatically interpreted as an external object.
Does NASA investigate UFOs?
This page features reports of sightings documented by astronauts or investigated by NASA, alongside articles and interviews concerning unexplained observations. A single item or online video is not necessarily an official NASA finding.
