As part of Black Hole Week, NASA has remixed the spooky sound of a black hole. This means that it can also be heard by the human ear.
Towards the end of Black Hole Week, astrophysicists at NASA presented this year’s theme music on Wednesday, namely the soundtrack of a black hole. The sound waves identified by astronomers have been extracted and made audible to the human ear for the first time. At the same time, the result is proof that space does not seem silent. Black Hole Week is an annual NASA social media feature. This year, it will take place from May 2 to 6. This was reported by NASA.
On July 23, 1999, NASA launched Chandra (abbreviation: CXO, full name Chandra X-ray Observatory) into Earth orbit a satellite carrying an X-ray telescope. Chandra is considered the largest satellite NASA has ever launched. orbit on a space shuttle.
Chandra astronomers identify sound waves
In 2003, astrophysicists working with NASA’s orbiting Chandra X-ray Observatory discovered a ripple pattern in X-ray light from a cluster of giant galaxies in the constellation Perseus. The black hole at the center of the Perseus galaxy cluster has been associated with sound since its discovery.
These were sound waves with a diameter of 30,000 light years. Through the thin, ultra-hot gas, sound waves permeate the galaxy cluster and radiate outward. They are due to periodic explosions of a supermassive black hole at the center of the cluster. It is 250 million light years away and contains thousands of galaxies.
What does a black hole look like? : Black Hole Week Provides the Answers
Astronomers have discovered that the pressure waves emitted by the black hole cause sound waves in the hot gas in the cluster. This can result in sound. However, at about 57 octaves below middle C, the tone is inaudible to humans. The black hole has apparently been producing sound for two billion years.
Now Chandra astronomers are ringing those waves through a new sonification, a translation of astronomical data into sound. By accelerating signals to 57 or 58 octaves above their original pitch and increasing their frequency four billion times, they are then audible to the human ear. As a result, we can hear intergalactic tones.
Chandra Observatory Clear Error
“The common misconception that there is no sound in space stems from the fact that most of space is essentially a vacuum. This does not provide a medium for sound waves to propagate. A Galaxy clusters, on the other hand, contain a lot of gas, which envelops hundreds or even thousands of galaxies and at the same time forms a medium for the propagation of sound waves.
