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.
A plasma ball with filaments extending between the inner and outer spheres A plasma ball , plasma globe , or plasma lamp is a clear glass container filled with noble gases , usually a mixture of neon , krypton , and xenon , that has a high-voltage electrode in the center of the container.
Plasma as a blood product prepared from blood donations is used in blood transfusions, typically as fresh frozen plasma (FFP) or Plasma Frozen within 24 hours after phlebotomy (PF24). When donating whole blood or packed red blood cell (PRBC) transfusions, O- is the most desirable and is considered a "universal donor," since it has neither A nor ...
This black hole is the first to be imaged. Data to produce the image were taken in April 2017, the image was produced during 2018 and was published on 10 April 2019. [37] [83] [84] The image shows the shadow of the black hole, [85] surrounded by an asymmetric emission ring with a diameter of 690 AU (103 billion km; 64 billion mi). The shadow ...
Artistic representation of Earth's magnetosphere. The plasma sheet is highlighted in yellow. In the magnetosphere, the plasma sheet is a sheet-like region of denser (0.3-0.5 ions/cm 3 versus 0.01-0.02 in the lobes) [citation needed] hot plasma and lower magnetic field located on the magnetotail and near the equatorial plane, between the magnetosphere's north and south lobes.
The faint yellow area shown above the north pole represents gas lost from Earth into space; the green area is the aurora borealis—or plasma energy pouring back into the atmosphere. [1] The polar wind or plasma fountain is a permanent outflow of plasma from the polar regions of Earth's magnetosphere.

This is a loosely defined category listing types of plasma named by a prominent characteristic, such as the location (e.g., astrophysical plasma), a property (e.g., nonthermal plasma), mode of its generation (e.g., induction plasma), etc.
