How does a black hole “sound”? NASA shares amazing sounds from other galaxies
United States National Aeronautics and Space Administration (Container) He produced a new “sonication” of the characteristic black hole, which is located in the center of the Perseus Galaxy. Scientists were able to reproduce the “sound” of this astronomical phenomenon From translating all the information and data they receive from the universe.
This black hole It has been associated with sound since 2003, when astronomers discovered it The pressure waves emitted by the hot gas cause ripples from the block. These received frequencies can be translated into a musical note, Which humans can’t hear, about 57 phonemic answers under middle C.
In some ways, the new sonication is unlike anything that has been done before. This, because it reconsiders the actual sound waves detected in the data from X-ray Observatory: NASA’s Chandra.
According to NASA in a statement, The common misconception that there is no sound in space stems from the fact that most of space is essentially a vacuumwhich does not provide a medium for the propagation of sound waves. On the other hand, a cluster of galaxies contains abundant amounts of gas that swallow hundreds or even thousands of galaxies within.which provides a means for the transmission of sound waves.
In this new sonication of Perseus, The sound waves previously identified by astronomers were extracted and heard for the first time. They are drawn in radial directions, that is, away from the center. then itSignals in the human auditory range are reproduced by boosting them 57 and 58 octaves above the actual pitch.
Another way to express this is that You hear 144 quadrillion and 288 quadrillion times more than their original frequency. Radar-like scanning around the image allows you to hear the waves emitted in different directions. In the visual image of this data, blue and purple are shown X-ray data captured by Chandra.
In addition to the Perseus group of galaxies, NASA has produced a new sonication of another famous black hole. The black hole that scientists have studied for decades in Messier 87 (M87) It gained fame in science after being photographed by the Event Horizon Telescope (EHT) project in 2019.
This new audio does not provide EHT data, but rather It analyzes data from other telescopes that spotted M87 at much larger scales around the same time. The image in visible form contains three panels, top to bottom, X-rays from Chandra, optical light from the Hubble Space Telescope. NASA and radio waves subordinate Atacama Large Millimeter Array (ALMA), Chile. The brightest area to the left of the image is where the black hole is, and the structure in the upper right is a “jet”. Produced by material falling into a black hole.
Sonification scans the three-level image from left to right, With each wavelength assigned to a different set of audio tones. It maps radio waves to lower tones, optical data to midtones, and X-rays detected by Chandra to higher tones.. The brightest part of the image corresponds to the noisiest part of the sonication process, which is Where do astronomers find 6.5 billion black holes of solar masses captured by the EHT.
