We all know turbulence when we see it, whether it is smoke curling upwards from a cigarette or the patterns that milk makes in our coffee soon after we pour. Turbulence occurs pretty much everywhere and in everything, including in space where plasmas can play an important role. We find this plasma turbulence on the sun, in star forming regions, and even in the space between planets in our solar system. In turbulence, the wiggles that we see ultimately get damped into heat. In our morning coffee, this is relatively straightforward. However, in space plasmas, how this energy damps is a mystery. For example, the damping can create temperatures that are different depending on which direction you look! One way that might damp this energy is through magnetic explosions, so-called magnetic reconnection where magnetic energy is turned into heat. This presentations presents a new model about how these magnetic fields can help damp the turbulent energy and heat the plasma.
