Videos of eerie noises erupting from the skies have recently surfaced on YouTube, sending people into a panic around the world. The video above shows a particularly frightening episode of this phenomena recorded in Germany as a child stands in the street bewildered by what he's hearing.
Now NASA is stepping in to provide some insight into what could actually be causing this scary pattern. NASA scientists believe the ominous noises could potentially be the "background noise" of the Earth otherwise known as "Ambient Earth Noise." Since this still lacks scientific confirmation, rampant speculation continues about potential extra-terrestrial theories for these "trumpet noises."
But don't count NASA as a UFO-doubter just yet. NASA is considering adding a message to the New Horizons probe to communicate with alien life in the near future.
