Scientists have discovered that the "alien song" recorded from Earth's deepest point is actually the sound of a whale.

Have you heard about the mysterious noises coming from the Mariana Trench? For years, these eerie sounds have baffled scientists and sparked fears of an alien invasion. The Mariana Trench, located in the Pacific Ocean, is one of the most mysterious places on Earth, with depths reaching 37,000 feet and few people daring to explore its depths.

Back in 2014, these strange noises were first recorded, lasting between 2.5 and 3.5 seconds. They were dubbed "biotwangs" by scientists due to their unknown source. But now, after ten years, a team of researchers from the National Oceanic and Atmospheric Administration (NOAA) have finally solved the mystery.

According to a report from the Mail Online, the sounds were actually recorded by underwater gliders that were conducting acoustic surveys of the Mariana Trench. It turns out, these noises were not from an alien civilization, but rather from a species of whale.

The study, led by Dr. Ann Allen, revealed that the "biotwangs" were actually produced by Bryde's whales, a type of baleen whale. This confirms a theory proposed in 2016 by scientists from Oregon State University, who believed the strange sounds could be a previously unheard whale call.

Sharon Nieukirk, a senior faculty research assistant at the university, described the call as "very distinct" and "twangy." She also mentioned that they don't often come across new baleen whale calls, making this discovery even more exciting.

Thanks to advancements in technology, the team was able to analyze the noises again, this time using a combination of visual and acoustic data. They found that the Bryde's whales were consistently present in the Mariana Archipelago, with occasional appearances in other areas such as the Northwestern Hawaiian Islands and near the equator.

But how exactly do these whales produce such a unique sound? According to Dr. Allen, it's possible that they use it as a form of communication, similar to a "Marco Polo" game in the ocean. However, more research is needed to fully understand the purpose of this call.

The discovery of the source of these mysterious noises has been published in the Frontiers in Marine Science journal and has put an end to the speculation of an alien invasion. But the Mariana Trench still remains a mysterious and little-explored place, where only a few have ventured to uncover its secrets.
