NASA uses data sonification to produce sounds of a black hole, galaxy and nebula

The National Aeronautics and Space Administration (NASA) has left people flabbergasted by turning dry, lifeless data from black holes, galaxies, and stars into music. Although it is impossible to hear the sound of the universe, because it is empty, NASA used the data specification process to create their sounds. In an online statement, the space agency revealed that all the data was collected using the Chandra X-ray Observatory and other telescopes.

Three amazing sounds

The first clip they shared was Chandra Deep Field South and they represented the space telescope spanning over seven million seconds of time. Describing the video, NASA wrote “Almost all dots of different colors are black holes or galaxies. Most of their predecessors are the enormous black holes that inhabit the centers of galaxies. In this data specification, the colors set the tones as the bar moves from the bottom of the image to the top. In particular, colors towards the red end of the rainbow are heard as low tones while colors towards purple are assigned to higher tones. The light that appears white in the image is heard as a white sound. ”

The second video they shared was the one at Cat’s Eye Nebula. NASA revealed that when stars run out of helium to burn, they blow up clouds of dust and gas. It was these “amazing” bubbles from the Cat’s eye nebula that were captured by Chandra and Hubble’s telescopes and now transformed into sounds.

“To listen to this data, a clockwise-like radar scan comes from the center to produce an output. The light farther from the center is heard as higher fields while brighter light is higher. The X-rays are represented by a louder sound, while the visible light data is more stable. The round rings form a stable hum, laid down by a few sounds from paws in the data, “NASA explained in a statement.

The third fragment features the galaxy Messier 51 (M51) or galaxy Whirlpool. Like the Cat’s Eye, the sonification starts at the top and moves radically around the image in a clockwise direction. The radius is mapped to notes of small melodic scale. Every wave of light in the image that is received from NASA telescopes in space (infrared, optical, ultraviolet, and X-ray) is assigned to a different frequency range, ”said NASA. associated with the clear heart to always be heard.
