ANCHORAGE - A years-long research project conducted by Finland's Aalto University suggests the aurora borealis is more than just pretty lights in the night sky.
Video collected as part of the Auroral Accoustics project captured the noise on three separate microphones placed nearly 230 feet off the ground. The project collected sound samples from several locations around Finland over many years, but it wasn't until May 2012 the clapping noise was first discovered.
While researchers said the video is far from scientific proof of auroral sounds, it represented the first instance in the project's history noise from the northern lights was captured simultaneously on multiple microphones.
