Light is composed of electromagnetic waves, which do not need a medium to travel: this is why light from distant stars can reach the Earth and travel through the void of space. On the other hand, sound consists of mechanical waves, which means that it needs to travel through a substance, such as water or gas, to announce itself and although the sound may not literally be able to reach human ears from these distant celestial bodies, the transmission of data To sound that can alert the brain to relationships between different wavelengths on the electromagnetic spectrum by using musical separators to represent differences or similarities in the data. The creators of this project highlight different elements in each video.
The Chandra Deep Field South is the deepest image captured in an X-ray, and the colored dots represent the galaxies or supermassive black holes that live in the centers of galaxies. The full range of X-ray wavelengths in this field is enormous, so to photograph it, scientists used red for low-energy X-rays, green for medium-power and blue for high-energy X-rays and these sounds take the one-dimensional color field and turn it into a virtual experiment where sound transmits active variations and wrote. NASA officials in a press release describing the videos: “They are played as sound … the full range of data can be experienced.” Stereo mode for sounds also helps the viewer see if the pitch matches the color on the left or right side of the image.
A feeling of “flying through space” comes from a data sonication video made from the Cat’s Eye Nebula. This is because the sound in this video illustrates what is happening at different distances from the center of the spectacular nebula. NASA officials wrote: “The highs and lows of sound that can be heard are caused by scanning the radar that passes through the explosions and beams in the nebula.” The X-ray data from Chandra were imaged using what she described. As the “harshest” and discordant sound of data sonication for the Messier 51 galaxy, NASA visualizes observations from Hubble, Chandra, the former NASA Spitzer infrared space telescope and the former GALEX space agency’s ultraviolet telescope.
