New audio tapes released by NASA have revealed “outer-space music” heard during transits around the far side of the moon.
The new tapes reveal audio between astronauts Eugene Cernan and John Young discussing the strange noises, which were heard during a mission in 1969. The tapes are part of a new Science Channel series, NASA’s Unexplained Files; you can watch a portion of the episode above.
“Sounds like, you know, outer-space type music,” says one of the astronauts.
The recordings were previously archived and classified for the past several decades and were only just made public. A portion of the transcript, which was originally shared in 2008 and registers at over 500 pages, can be seen below.
The actual source of the noise is still being disputed by NASA engineers. One NASA technician believes the whistling was a result of radio interference while others think it’s something else.
Michael Collins, who flew over the dark side of the moon during the Apollo 11 mission, also reported hearing an “eerie woo-woo sound,” but said he had been warned by technicians beforehand that he might run into some sort of interference.
