[h=2]Nasa still cannot explain the eerie hisses and whistles recorded by special microphones 22 miles above the earth's surface[/h]
Mysterious hisses and whistles have been recorded 22 miles above the earth's surface using infrared microphones aboard a Nasa sutdent balloon experiment.
The 'infrasounds' were captured by Daniel Bowman, a student at the University of North Carolina, accoridng to a report in LiveScience.
The sounds can only be heard by human ears after speeding up the recordings and were picked up at frequencies below 20 hertz.
'It sounds kind of like The X-Files,' Mr Bowman told Live Science.
Infrasonic sound can travel long distances and natural phenomenon such as earthquakes and storms can cause infrasounds, but researchers still do not know what was picked up in these recordings.
