Unexplained alien sounds recorded at the edge of space 22 miles from Earth’s surface baffle scientists

These new eerie ‘alien sounds’ have been recorded 22 MILES above Earth by NASA.

This new sound recording from the edge of space has unexplained hisses and whistles that puzzle scientists!

This is the first time in 50 years that eerie sounds from the edge of space have been recorded aboard a NASA student balloon experiment and that at 22 miles (36 kilometers) above the Earth’s surface.

The mysterious infrasound hisses and whistles are baffling the scientific community:

Several hypothesis exist for the origin of these ‘alien sounds‘:

  • Signals from a wind farm under the balloon’s flight path
  • Crashing ocean waves
  • Wind turbulence
  • Gravity waves
  • Clear air turbulence
  • Vibrations caused by the balloon cable.

Storms, earthquakes, volcanoes, avalanches and meteors all produce infrasonic sound waves, which carry for long distances. Infrasound is below human hearing range, but speeding up the recordings makes them audible.

I find that this weird signal is really complex and kind of creepy!
