(NLĐO) - The NASA clip includes a haunting audio segment, showcasing sound waves emanating from the "monster heart" of the Perseus galaxy cluster.
Science Alert has just published a terrifying clip provided by NASA, in which a mesmerizing space object is emitting a monstrous roar.
It is a supermassive black hole—often called a monster black hole—located at the center of the Perseus galaxy cluster, also known as the Perseus star cluster because, viewed from Earth, the galaxies in the cluster look like stars.

In 2003, astronomers made a truly astonishing discovery: Sound waves were propagating through the vast amount of gas surrounding this black hole, which had previously been known for its strange "whining" sounds.
In reality, the human ear cannot perceive these sound waves in the way we hear them in the NASA clip, but the American space agency has boosted the tone by several dozen octaves to make it sound audible to us.
The frequency of the audio segment released by NASA is also 144-288 trillion times higher than the original pitch.
Sound waves actually comprise the lowest notes in the universe that humans have ever detected, and of course, this is far below the limits of human hearing.

Additionally, NASA also added some notes from individual sounds emanating from the black hole to the audio track to complete the eerie "music," which is truly spreading through intergalactic space.
Sound waves propagating through the environment within a galaxy cluster are a mechanism that helps heat that environment itself, as they transfer energy through the plasma.
Since temperature helps regulate star formation, sound waves may play a crucial role in the long-term evolution of galaxy clusters.
That temperature also allows us to detect sound waves. Because the environment inside the cluster is so hot, it glows brightly in X-rays, which is what NASA's Chandra X-ray Observatory has captured.
