Original Note:
This is an x-ray image of gas in the Perseus cluster, which is dense enough to allow pressure waves. NASA used the image above to determine a period of vibration of the gas (~9.6 million years) and increased the frequency 144/288 quadrillion times to produce audible sound. https://chandra.harvard.edu/chronicle/0303/perseus/index.html https://www.nasa.gov/universe/new-nasa-black-hole-sonifications-with-a-remix/ https://www.physicsclassroom.com/class/sound/u11l1c.cfm
