Since 2003, scientists National Aeronautics and Space Administration (NASA) Different has been revealed Sounds that exist in space. Now he The sound of a black hole in the Perseus galaxy cluster Published as part of NASA Black Hole Week 2022. it’s not Science fiction.
The new sound emitted by NASA’s black hole sounds like this:
To get it New sound from space, Astronomers isolated sound waves, which were first heard and previously recognized.
Sound waves are drawn in radial directions, i.e., away from the center. The signals were amplified from their original pitch to 57 and 58 octaves and reconnected to the human hearing range.
That is to say, it is Sound waves are heard at 44 quadrillion and 288 quadrillion more than their actual frequency.
- One quadrillion is 1,000,000,000,000,000,000.
A radar-like scan around the image allows you to observe the waves emitted in different directions. In the visual image of this data, blue and purple lunar X-ray data are shown.
In the opinion of experts, this New black hole sound This is different from what it did before because it revisits the actual sound waves detected by data from NASA’s Lunar X – ray Observatory.
These sonifications, made by the Lunar X-Ray Center (CXC), are included as part of NASA’s Universe of Learning (UoL) program with additional support from the Hubble Space Telescope / NASA Goddard Space Flight Center.
Other space sounds
as well as Perseus cluster of galaxiesA launches The new sonication of another famous black hole, Scientists have studied for decades that Messier 87, or the black hole in M87, became a celebrity in science after the first launch of the 2019 Event Horizon Telescope (EHT) project.
This is new The sound of the place EHT does not present data, but instead looks at data from other telescopes that observe the M87 on very large scales at the same time.
Sounds in space, and how do they originate?
The popular notion that there are no sounds in space is wrong. Experts explain that this belief stems from the fact that most space is basically a vacuum, so there is no medium for sound waves to propagate.
However, galactic clusters contain large amounts of gas, which swallow up hundreds or thousands of galaxies, providing a medium for sound waves to travel.
in the case of Black holes, Because astronomers have discovered that the pressure waves emitted by a black hole can cause waves in hot gas in the cluster, this sound can be translated from the middle C below 57 octaves into a note inaudible to humans.
