It is a sonification — translation into sound — of the newest picture from the Occasion Horizon Telescope (EHT) of the supermassive black gap on the middle of the Milky Method referred to as Sagittarius A* (Sgr A*). Utilizing a radar-like scan, the sonification begins on the 12 o’clock place and sweeps clockwise. Modifications within the quantity symbolize the variations in brightness the EHT noticed across the occasion horizon of Sgr A*. The fabric that's nearer to the black gap and therefore shifting sooner corresponds to increased frequencies of sound. This sonification was processed in a particular solution to permit a listener to listen to the information in 3D stereo sound, wherein the sounds appear to start out instantly forward after which transfer clockwise to at least one ear after which the opposite because the sweep is made.
In regards to the Sound:
- It is a radar-like scan, ranging from 12 o’clock and shifting clockwise.
- The brightness controls the quantity and the radial place controls the frequencies which are current.
- The emission from materials nearer to the black gap (which orbits sooner) is mapped to increased frequencies.
- The sound is rendered in binaural audio. When listened to with headphones, the sound will seem to start out instantly in entrance of you after which transfer clockwise all the best way round your head.
- Pay attention for the three vibrant areas at about 1, 5, and 9 o’clock, in addition to the very low tones indicating fainter gentle from exterior the primary ring.
