Dude, what are those humongous plasma waves in Jupiter’s atmosphere? en (arstechnica.com)

There are waves on Jupiter, but not exactly the kind surfers can ride. These plasma waves are much more intense than anything that crashes onto a beach.

NASA’s Juno spacecraft keeps coming across humongous plasma waves as it orbits Jupiter. These waves are actually known as Kelvin-Helmholtz instabilities (KHIs), and they occur when plasma from the solar wind interacts with the magnetopause of a planet, the outer level of its magnetic field. The difference in velocity between the magnetopause and solar wind creates a furiously swirling wave—a vortex.
