Turbulence, also known as plasma turbulence in space, is a chaotic state of motion within the interstellar medium (ISM), the space between stars. This turbulence, driven by Alfven waves (named after the Swedish, Nobel laureate plasma physicist), is a major factor in shaping star formation, the behavior of magnetic fields, and the structure of galaxies. This image shows that even so-called empty space is incredibly dynamic. (From New Thinking Allowed)
