"Biotwang" noises sound like sci-fi Star Trek and Star Wars sounds coming from deepest ocean trench.

Scientists first detected the noises in 2014 while using underwater gliders to carry out an acoustic survey of the Mariana Trench .

In 2016 , researchers revealed that biotwang was most likely a call from large baleen whales, such as blue whales or humpback whales.
