Data Sonification: Saturn, Composite

In late February, people in the northern hemisphere can look up for a special sight: six planets will all be visible from clear and dark night skies. Since the planets in our Solar System travel around the Sun in same plane (known as the ecliptic), they will sometimes appear bunched together on the sky if their orbits find them on the same side of the Sun at the same time. When this happens, it looks like the planets have roughly formed a line from our vantage point on Earth. Original sonifications from NASA’s Chandra X-ray Observatory help commemorate this latest “planet parade”. Saturn: The scan of Saturn begins on the right and moves to the left. As it encounters Saturn’s famous rings, seen in an optical image from the Cassini mission, we hear almost a siren effect whose frequency follows the arc of the rings. Once the scan reaches the planet itself, the sounds change and we hear lower tones with a dark synthetic bass sound. This distinguishes the rings from the planet. Chandra’s X-rays are heard as higher synthetic tones that mark where high-energy activity is found across the planet, rings, and poles. Sonification: NASA/CXC/SAO/K.Arcand, SYSTEM Sounds (M.
