US government declassifies dozens of additional UFO files, including strange military videos

Editor's note: On Friday (May 22) the Department of Defense released a second tranche of UFO files, adding another 60 documents to its ongoing database. These include new videos from the military, and documents dating back to the 1970s. This article, originally published May 8, has been updated as Live Science reviews the files for possible items of interest.

UFOs have come to Washington again — this time, in a newly released tranche of more than 150 previously classified documents that cover nearly 80 years of alleged sightings.

Available to read today (May 8) on the Department of Defense website, the 162 newly declassified documents, photos, and videos cover reports of UFOs and UAP (unidentified anomalous phenomena, the government's preferred name for such sightings today) dating back as far as 1947.

The reports come from agencies across the government, including the Department of Defense (DOD), the FBI and NASA. The NASA offerings include images, audio files and transcripts of Apollo-era astronauts reporting anomalous sightings in space. However, most of these materials have been available for decades and never resulted in any compelling answers.

"The materials archived here are unresolved cases, meaning the government is unable to make a definitive determination on the nature of the observed phenomena," DOD representatives wrote on the agency's website. "This can occur for a variety of reasons, including a lack of sufficient data."

Are there any aliens?

Due to the poor data quality, the reports do not contain any compelling evidence of alien intelligence.

While NASA has not weighed in directly on the newly declassified files — save for a statement of support from Administrator Jared Isaacman — the space agency's official position remains that UAP are real but they have nothing to do with aliens.

"Are there any data supporting the idea that UAP are evidence of alien technologies?

"No," NASA's official UAP webpage states. "Most UAP sightings result in very limited data, making it difficult to draw scientific conclusions."

Indeed, NASA conducted its own independent investigation into UAP sightings in 2022 and 2023 and found no evidence of alien activity, again pointing to low-quality data among the alleged sightings.

What did the NASA astronauts see?

Some of the most interesting documents, from a historical perspective, are files related to UFO sightings reported by NASA astronauts in the 1960s. They include a transcript and audio recording of two NASA astronauts reporting an unidentified object in Earth orbit during the 1965 Gemini VII mission.

Just four hours into the flight on Dec. 5, 1965, astronauts Frank Borman and Jim Lovell reported seeing a "bogey" (military slang for an unidentified aircraft) out their spacecraft window, which Borman describes as "hundreds of little particles going by."

When NASA ground control pressed Borman on whether it could be a piece of the recently detached rocket booster, the astronauts said no, maintaining that they could see the booster in a separate part of orbit. The Gemini spacecraft soon drifted away from the object, never to see it again.

The files also include photos and transcripts from the Apollo 11, Apollo 12 and Apollo 17 missions, in which astronauts describe seeing various unidentified "flashes" and "particles of light" on the moon. These cases, like the others, remain unresolved due to a lack of sufficient data.

The underlying files have been available in public archives for decades. However, some newly released images from the Apollo 12 mission show zoomed-in boxes to highlight anomalous phenomena on the moon.

What are UAP?

So, if they're not aliens, what are UAP? According to a 2022 DOD investigation, most UAP sightings can be explained by birds, optical illusions, poor-quality photographs and foreign surveillance technology.

Many UAP files remain classified not due to the object sightings themselves, but because of the sensitive military technology used to record them, according to NASA.

The DOD plans to release additional declassified UAP documents every few weeks for the near future.
