On Sunday, NASA posted on Twitter the sound emitted by a black hole 250 million light-years from Earth. If the recording was made in 2003, it would be barely perceptible to the human ear.
After galactic images captured by the James-Webb telescope, after the transmission of a dazzling shot of Jupiter, after seeing a dying star or a photo of a black hole, when NASA communicates about its next project landing, the American agency expands the list of recent successes in space research.
The sound emitted by the black hole was published by the firm on Twitter on Sunday. A sound as charming as a wail, which you can listen to below.
The intriguing melody comes from the immediate environment of a black hole located at the heart of the Perseus Galaxy, or 250 million light-years from our Earth, according to the Anglo-Saxon spelling. As the site notes here motherboard.
Sharing allows NASA to dot the eyes and dispel the accepted notion that space is being pushed into silence. NASA of course nuances:
“The misconception that there is no sound in space stems from the fact that most of space is a vacuum—there is no way for sound waves to propagate. (But) a cluster of galaxies has so much gas that we can pick up real sound. .”
To be honest, the collection took place some time ago. More precisely, it was recorded in 2003 by NASA’s Chandra X-ray Observatory. Problem: Ordinary people couldn’t hear it yet. “In this new Perseus sound system, sound waves previously detected by astronomers are made audible for the first time,” the agency points out.
In detail, NASA amplifies its frequencies and raises them by several “quadrillion times,” meaning millions of times. An increase in their range and volume that allows us to finally hear this song of the universe.
