EUROPE: The recent alien hunting projects of several teams might be another failure, but some unusual sounds were captured by a balloon experiment set up by NASA, which they think could possibly come from another alien life.
The balloon carries an infrasound microscope that is able to record sound waves in the atmosphere at frequencies lower than 20 hertz. The device is floating just 22 miles above the Earth when it picked up the strange sound.
It was Daniel Bowman, a student from the University of North Carolina, who designed and built the balloon equipment used in the study. The initial program managed by NASA and the Louisiana Space Consortium tested the flight of the equipment where they captured sounds from the atmosphere of Arizona and New Mexico. It was just one of the ten experiments flown atop of the High Altitude Student Platform that successfully picked up the sounds. The said program was able to launch more than 70 student experiments in search of a successful project since 2006.
As that one balloon fly over the height of 37,500 meters above Earth for 9 hours, which is just below the top of the stratosphere and higher than the flight height of airplanes, it got the record of the highest point an equipment carrying infrasound has ever reached.
But the record is not all that, the sound captured by the balloon is what researchers claimed as a signal that they never encountered before.
