After the galactic images captured by the James-Webb telescope, after the emission of a dazzling shot of Jupiter, after the sighting of a dying star or the photo of a black hole, and while NASA communicates about its next landing project, the US agency has further expanded the list of recent successes in space research.
Indeed, the institution published, on Sunday on Twitter, the sound emitted by a black hole. A noise, as fascinating as it is gloomy, that you can hear below.
L’intriguing mélopée coming from the environment immédiat d’un trou noir situated in the heart of the galaxie Persée ou Perseus selon l’orthographe Anglo-Saxonne, soit à 250 million d’années-lumière de notre terre, comme le note ici the place Motherboard.
Sharing allows NASA to splash the i’s and dispel the received idea that space is doomed to silence. NASA in fact clarifies:
“The fallacy that there is no sound in space stems from the fact that space is mostly a vacuum, which gives no way for sound waves to propagate. (But) a galaxy cluster has so much gas that we could capture real sound.”
To be honest, the collection took place a while ago. More precisely, NASA’s Chandra X-ray Observatory recorded it in 2003. Problem: It wasn’t audible to ordinary mortals until now. In this new Perseus sound system, sound waves that astronomers had previously identified are made audible for the first time.
In detail, NASA has carried out a work of amplification of their frequencies, raising them several “quadrillion times”, that is, millions of billions of times. An increase in its range and volume that allows us today to finally hear this song of the universe.
