1997 National Oceanic and Atmospheric Administration hydrophones detected and captured by deep sea microphones the loudest sound ever, named “The Bloop”. What created this strange sound in Earth's Pacific Ocean?
Although Bloops are some of the loudest sounds of any type ever recorded in Earth's oceans, their origin remains unknown. The Bloop sound was placed as occurring several times off the southern coast of South America and was audible 5,000 kilometers away.
Although the sound has similarities to those vocalized by living organisms, not even a blue whale is large enough to croon this loud.
The sounds point to the intriguing hypothesis that even larger life forms lurk in the unexplored darkness of Earth's deep oceans. No further Bloops have been heard since 1997, although other loud and unexplained sounds have been recorded.

Could aliens be living under the sea?
