NASA’s sonification of RS Puppis, a cepheid variable star located 6,500 light-years from Earth, lets you hear what one of the brightest and biggest stars in the Mihttps://www.techeblog.com/sonification-of-rs-puppis-star/lky Way galaxy could sound like. It’s 200 times larger than our Sun and draped with dust reflecting starlight, rhythmically brightening and dimming over a six-week cycle.
What do you hear in this sonification? Scientists represented data in the image as sound. In other words, the pitch is assigned based on direction from the center, and as the circle travels inward, light closer to the top is high pitched, while light closer to the bottom is lower. The light toward the left is heard more in the left speaker and light toward the right is heard more in the right speaker. Plus, the brighter parts of the image are mapped to louder volumes.
