Conceptual steps towards exploring the fundamental nature of our Sun
... Despite of its plasma state, the solar core is widely regarded as being in a gaseous state. Plasma nature of the solar core has been ignored because of the general assumption that the solar core is quiescent and, therefore, being static, the solar core does not show any peculiar plasma behavior.

This yields distinct streams of heterogeneous plasma, downwind from the comet, with different sources for the ions and electrons in each stream (Fig. 1). ...

Microplasma
Microplasmas are plasmas of small dimensions, ranging from tens to thousands of micrometers. They can be generated at a variety of temperatures and pressures, existing as either thermal or non-thermal plasmas. Non-thermal microplasmas that can maintain their state at standard temperatures and pressures are readily available and accessible to scientists as they can be easily sustained and manipulated under standard conditions. Therefore, they can be employed for commercial, industrial, and medical applications, giving rise to the evolving field of microplasmas.
