The plasma approximation: The plasma approximation applies when the plasma parameter Λ, [26] representing the number of charge carriers within the Debye sphere is much higher than unity. [ 19 ] [ 20 ] It can be readily shown that this criterion is equivalent to smallness of the ratio of the plasma electrostatic and thermal energy densities.
The plasma of the magnetosphere has many different levels of temperature and concentration. The coldest magnetospheric plasma is most often found in the plasmasphere. However, plasma from the plasmasphere can be detected throughout the magnetosphere because it gets blown around by the Earth's electric and magnetic fields.
Astrophysical plasma is plasma outside of the Solar System. It is studied as part of astrophysics and is commonly observed in space. [2] The accepted view of scientists is that much of the baryonic matter in the universe exists in this state. [3] When matter becomes sufficiently hot and energetic, it becomes ionized and forms a plasma.
The plasma state is often misunderstood, and although not freely existing under normal conditions on Earth, it is quite commonly generated by either lightning, electric sparks, fluorescent lights, neon lights or in plasma televisions. The Sun's corona, some types of flame, and stars are all examples of illuminated matter in the plasma state.
Astronomers have detected more evidence that Saturn’s moon Enceladus may be one of the most promising places to search for life beyond Earth. Life may have everything it needs to exist on Saturn ...
Farther out, field lines can be significantly distorted by the flow of electrically conducting plasma, as emitted from the Sun (i.e., the solar wind) or a nearby star. [ 3 ] [ 4 ] Planets having active magnetospheres, like the Earth, are capable of mitigating or blocking the effects of solar radiation or cosmic radiation .
In 2007 Russian expert in plasma physics Vadim Tsytovich together with German and Australian colleagues published a paper in which they speculated about plasma-based inorganic living matter, extrapolating from computer simulations of self-organization reported in plasma. [11] [12] The simulated conditions can exist in nebulae. Tsytovich claims ...
