The Department of War on Friday released a second round of declassified Unidentified Anomalous Phenomena files, including three newly published military videos and hundreds of pages of historical government documents detailing decades of unexplained sightings.

The release includes infrared footage allegedly captured by U.S. military platforms in the Middle East, Cold War-era investigation files involving mysterious “green orbs,” a CIA report describing a glowing object spotted in the Soviet Union in 1973, and audio files of astronaut accounts from the Apollo 12 mission.
