<p>Daphnis is a small moon of Saturn, just 3.8 km in radius. It moves within a narrow gap in the planet's rings, and due to its gravity, it raises waves of ring particles. The particles inside the gap move faster, while those outside move slower, causing the waves to 'wiggle' back and forth. NASA photographs show ridges of dust and ice trailing behind the moon. These waves smooth out over time as particles collide with each other. Daphnis was discovered in 2005 - first the waves were noticed, and then the moon itself was found. It completes one orbit around Saturn in 14 hours.</p>
<p>P.S. It would be interesting to record this wave on a vinyl and listen to it - maybe there’s a message to humanity?</p>
