History
Voyager approaches a plasma drift. A plasma drift is a nebula-like interstellar phenomenon.

plasma consists of a gas heated to sufficiently high temperatures that the atoms ionize.

PLASMA
A plasma is an extremely hot gas that is composed of free-floating ions (atomic nuclei stripped of some electrons - making the ions positively charged) and free electrons (negatively charged).

ion: An atom that has lost or gained one or more electrons.
ionization: The process in which atoms lose or gain electrons.
Gas and plasma phases
Helium is the least reactive member of the noble gas elements, and thus also the least reactive of all elements; it is inert and monatomic in virtually all conditions.

How do the solar wind parameters change as the comet is approached?
Plasmas, the fourth phase of matter (after solid, liquid, and gas), are responsible for the glowing clouds of matter we see in extreme conditions.
Plasma filament that extends from the solar corona.
A prominence is made up of relatively cold, dense plasma supported by the local magnetic field from falling back into the sun. They can survive like this for 200 days.
Plasma is a fluid with the ability to carry electric currents with no local accumulations of electric charge. The magnetic field exerts a force on the entire plasma. The magnetic field exert a force on the currents.

A form of ionized gas in which the temperature is too high for atoms to exist in their natural state. Plasma is composed of free electrons and free atomic nuclei.
The plasma torus indicated in the preceding figure is associated with the orbit of Io. As we will see, Io has multiple active volcanoes on its surface.
Solar wind plasma particles can leak through the magnetopause, the boundary of the magnetosphere, and populate its interior; charged particles from the ionosphere also enter the magnetosphere.

It is used as a plasma-beam source by permitting the plasma to stream out along the magnetic field through a hole in one of the cathodes.

solar wind a tenuous flow of gas and energetic charged particles, mostly protons and electrons -- plasma -- which stream from the Sun; typical solar wind velocities are near 350 kilometers per second.
This is so hot that the gas that makes up the Sun becomes a plasma. A plasma is a gas in which the electrons are stripped of their atoms and are free to move. This is similar to the gas in fluorescent light tubes.
NASA's International Cometary Explorer (ICE) passed through the plasma tail of 21P/Giacobini-Zinner in 1985. After this encounter, ICE joined a fleet of other spacecraft observing 1P/Halley.
The ionization of an atom in a plasma has two effects. First, the heat capacity of the plasma is larger within than outside the temperature range over which ionization occurs.
In response to this unstable condition, the newly created magnetic lines in the interior of the tail contract rapidly, thereby sending plasma from the neutral sheet of the magnetosphere toward the night side of the Earth.
The intense magnetic field and plasma that are believed to surround a neutron star provide an effective source of radio waves.
The magnetospheric plasma has an abundance of electrons: some are magnetically trapped, some reside in the magnetotail, and some exist in the upward extension of the ionosphere, which may extend (with diminishing density) some 25, ...
The multiple scattering of photons by a hot plasma in the early Universe should result in a blackbody spectrum for the photons once they have escaped at the epoch of reionisation. This is exactly what is observed for the CMB.
physicist Robert Erhlich, who has been modelling Sol's core based upon recent work on magnetic instabilities (Grandpierre and Ágoston, 2005), published calculations on how core magnetic fields may produce small instabilities in the Solar plasma that ...
The high temperature plasma in the core is about ten times denser than a dense metal on Earth. A photon can only travel a centimeter or so on average in the core before interacting with and scattering from an electron or positive ion.
The scattering is mostly off of electrons in the gas that have been stripped off of the atoms by the high temperature (an ionized gas known as a plasma). This "resistance" to the free travel of photons through the gas is called opacity, as in opaque.
A plasma of protons and electrons surrounds Uranus, circulating at the same rate as the planet spins, with a period of 17 hours. Ariel's orbit around Uranus takes a much longer 60 hours, so the faster-moving plasma overtakes the moon from behind.
The solar wind of high-speed protons and electrons sweeps cometary ions in a direction away from the Sun, producing a straight plasma tail. A second tail consisting of dust particles about a micrometer in size may appear.
A magnetic storm is a temporary perturbation (disruption) of the Earth's magnetic field, caused by solar flares, which eject plasma from the Sun's chromosphere.
From its launch in 1997 until it arrived in the Saturnian system in July 2004, the spacecraft measured interplanetary dust particles and observed the nature of the highly-ionised gas (plasma) that fills interplanetary space, ...
Further speculation along this line, however, shows that while the plasma would contain ions that quickly recombine to generate heat and light, ...
Plasma densities range from 1 - 10 ions/cc. The ions are about 95% , 4% and 1% heavier components. Assuming an average velocity of 400 km/s () and a plasma density of 3/cc (), we can calculate the solar wind force on a sail of a square meter.
Coronal mass ejections (CME's) are huge, balloon-shaped plasma bursts that come from the Sun.
