Structure in the unstructured: New phenomenon discovered in the solar wind

Turbulence is ubiquitous and occurs every day, such as when milk is stirred into coffee or in the stormy motions of the ocean and the atmosphere. Media in space and astrophysical systems can also develop turbulence, but the physics is different because the medium is in an ionized state (known as the plasma state) and the flow motion is strongly coupled to electromagnetic fields. Furthermore, space plasma is collisionless because the medium is so dilute that the particles do not collide with each other.
