Named after the two great men of science who made pioneering contributions to Fluid Dynamics, the Kelvin-Helmholtz instability is observed in a wide range of phenomena both on Earth and beyond. For instance, the Red Spot of Jupiter, the Sun’s corona and the bands of Saturn.
These Kelvin-Helmholtz clouds were seen on Christmas eve last year in the Mojave Desert outside the town of Ridgecrest, California.
