Abstract. Complex plasmas may naturally self-organize themselves into stable interacting helical structures that exhibit features normally attributed to organic living matter.

The self-organization is based on non-trivial physical mechanisms of plasma interactions involving over-screening of plasma polarization. As a result, each helical string composed of solid micro particles is topologically and dynamically controlled by plasma uxes leading to particle charging and over-screening, the latter providing attraction even among helical strings of the same charge sign. These interacting complex structures exhibit thermodynamic and evolutionary features thought to be peculiar only to living matter such as bifurcations that serve as ‘memory marks’, self-duplication, metabolic rates in a thermo dynamically open system, and non-Hamiltonian dynamics.

We examine the salient features of this new complex ‘state of soft matter’ in light of the autonomy, evolution, progenity and auto poiesis principles used to dene life.

It is concluded that complex self-organized plasma structures exhibit all the necessary properties to qualify them as candidates for inorganic living matter that may exist in space provided certain conditions allow them to evolve naturally.
