NASA Student Records ‘Alien Sound’ 22 Miles Above Earth Surface
Daniel Bowman, one of the students from University of North Carolina at Chapel Hill, has recorded mysterious sounds from the edge of space. The recording contains unexplained hisses and whistles just 22 miles above the surface of the Earth.
The recording came for the first time in 50 years while Bowman was conducting a balloon experiment. Infrared microphones were used to record what is described as an “alien sound“ by the Daily Mail.
The sound captured can only be heard when the audio is sped up. The frequency of the sound was below 20 hertz.
The student told Live Science, “It sounds kind of like ‘The X-Files.'”
“I was surprised by the sheer complexity of the signal.”
According to the report from Live Science, scientists have planned another balloon launch in 2015 that can provide more ideas about the strange infrasound sources.
Lots of speculations are being made about NASA’s discovery. While it is possible for natural calamities such as earthquakes and storms to produce infrasounds, it is still unknown what caused this particular sound.
The infrasound sensor was dangling from a helium balloon. This is the first time it recorded such a sound. It was part of 70 experiments NASA has been conducting for college students since 2006.
The balloon floated 450 miles across the Earth and reached a height of 123,000 feet. Daniel Bowman said, “Surely, if we place instruments up there, we will find things we haven’t seen before.”
