Daniel Bowman, a University of North Carolina graduate student, has managed to record what he calls alien space sounds in the stratosphere of our planet.
Bowman recorded the strange noises using special microphones that are ultra sensitive and were mounted on a high-altitude scientific balloon.
Bowman captured the infra-sonic sounds using his special balloon during a scientific study he was conducting for NASA and the Louisiana Space Consortium.
The project is called High Altitude Student Platform and it aims to make students interested in learning more about space.
Bowman’s high-altitude helium balloon was up in the sky at a height of 22 miles above New Mexico and Arizona when it captured the mysterious noise.
According to NASA experts, this is the first time someone records space sounds using a space balloon in more than 50 years.
The researchers said the balloon traveled for about 9 hours, flying across a total of 450 miles, reaching an altitude of more than 123,000 ft.
Bowman stated in an interview for Live Science that the sounds his balloon captured were somehow similar to the theme song from the popular sci-fi TV show The X Files.
According to Bowman, he was very surprised to see that the signal was very complex. The researcher said that he was expecting to see only a few small stripes.
Bowman’s discovery of the alien space sounds generated a number of theories from scientists who think they know what caused it.
Some believe that the noises were actually signals that come from a wind farm found below the balloon’s flight path.
Others theorize that what Bowman captures is nothing more than the sound of the crashing ocean waves.
Other possible explanations of the strange noises pointed out to things like turbulence, gravitational waves or vibrations form the cables of the balloon.
NASA is planning to release another space balloon later this year and scientists hope that this mission will help explain better the mysterious noises captured by the first balloon.
According to experts, infrasonic sounds can travel long distances and can only be hard at frequencies that are below 20 hertz.
Sources of terrestrial infrasound waves include volcanoes, avalanches, earthquakes and storms.
These sounds can also be made by a meteor passing, said the scientists.
NASA launched more than 70 experiments under the HASP project since it began in 2006.
All the balloons involved in the experiments were designed by students from colleges all over the U.S.
