Mystery of haunting ‘alien sound’ coming from deepest point on Earth solved!

Scientists finally find the source of mysterious sound in Mariana Trench

Scientists were stunned to hear mysterious sounds coming out from the deepest point on Earth — Mariana Trench. Autonomous vehicle captured the creepy 3.5 second audio recording which boggled everyone’s mind. Scientists wanted to know what is the actual source of the sound, whether it is natural or it is due to some unnatural force.

However, researchers from the Oregon State University say that they have identified the source of mysterious sound and it originated from a new type of baleen whale.

“It’s very distinct, with all these crazy parts,” says one of the team, Sharon Nieukirk from Oregon State University. “The low-frequency moaning part is typical of baleen whales, and it’s that kind of twangy sound that makes it really unique. We don’t find many new baleen whale calls.”

The sound has a very wide frequency range from 38 hertz to 8,000 hertz. You can hear the out of the world sound below:-

According to researchers, these sounds are very similar to the ones produced by the metallic components of the ships in underwater. Researchers also concluded that the sounds do not seem to be produced by natural activities like earthquake which produce low-frequency sound nor the sound was produced by biological source or wind.

Scientists were able to record the same mysterious sound on numerous occasions from autumn 2014 to spring 2015 in the Marianas Trench Marine National Monument – a 246,000 km2 (94,981 mile2) part of the Mariana Trench east of Guam, and one of the largest marine protected areas in the world.

“The complex structure of the Western Pacific Biotwang sound, the frequency sweep, and the metallic nature of the final part of this call are all very similar to characteristics of dwarf minke whale Star Wars calls,” the team concludes.

Some researchers also claim it to be a proof of alien life and said that aliens are producing these mysterious sounds. However, study authors conducted the study and found that these sounds were produced by the baleen whales that live the region. Scientists say that these whales produce different types of frequencies in a short span of time.

However, some researchers are still not satisfied with the discovery because these fish make sounds during mating season which falls in winter, but mysterious sounds were heard throughout the year.

“If it’s a mating call, why are we getting it year round? That’s a mystery,” says Nieukirk. “We need to determine how often the call occurs in summer versus winter, and how widely this call is really distributed.”

Researchers will now initiate another examination to confirm the exact source of this mysterious sound.

The study appeared in the journal of Acoustical Society of America.
