The solar wind isn't a calm stream but a bubbling soup of charged particles. Diving close to the Sun, the Parker probe picked up two types of stirring waves. Left-handed ones, like a whisk in a chef's hand, whip up the material when the temperature differs along and across the flow.

The Parker Solar Probe and Solar Orbiter spacecraft fly close to the Sun and measure the solar wind — the stream of charged particles that constantly blows from our star.
