'Chilling howls': NASA reveals spooky sound from a supermassive black hole – Listen here

NASA has released a haunting audio clip featuring sound waves from a supermassive black hole located 250 million light-years away. This eerie sound, transposed to be audible, was detected at the heart of the Perseus galaxy cluster.

The sound, captured for the first time, is a series of chilling howls. It's an unsettling, almost angry noise that has captivated listeners worldwide. The sound waves were extracted and raised in pitch so human ears could detect them. Sound Waves from the Heart of Perseus

In 2003, astronomers discovered acoustic waves emanating from the Perseus black hole. While these waves were too low in frequency for human ears to hear, their remarkable discovery led to a sonification project. This project allowed the waves to be transposed 57 and 58 octaves higher, enabling us to hear them.

The lowest note detected from the black hole was a B-flat, over 57 octaves below middle C. This frequency is so low that it would take 10 million years to complete one cycle.

The Role of Sound Waves in Galactic Evolution

These sound waves are more than just a curiosity. They help heat the gas and plasma in the galaxy cluster, which in turn plays a role in the evolution of these systems. The heat generated by these waves is crucial for star formation and galaxy cluster development.
