Cat's Eye Nebula

When a star like the Sun begins to run out of helium to burn, it expels huge clouds of gas and dust, forming spectacular structures such as the Cat's Eye Nebula. This sonification uses both X-rays from the Chandra telescope and visible light data from the Hubble Space Telescope to create an auditory representation of the nebula's features. The image reveals a series of bubbles expelled by the star over time, creating intricate patterns of light and sound.

The sonification employs a radar-like scan moving clockwise from the center of the image. Light further from the center is represented by higher pitches, while brighter light is mapped to louder sounds. X-rays are depicted with a harsher tone, while visible light data produce a smoother sound. The circular rings in the image generate a constant hum, punctuated by the sounds of spokes. The rising and falling pitches are a result of the radar scan passing across the nebula's shells and jets.
