To their surprise, Fox and his colleagues detected so much absorption of the background ultraviolet light that they concluded the Magellanic Stream must contain far
more ionized gas than neutral gas.

If clouds of hydrogen also cluster around quasars — which convert all nearby neutral hydrogen to invisible
ionized gas — then quasars must have
ionized more hydrogen than astronomers had assumed, Savaglio says.
These simulations get
more demanding and expensive as the temperature of the fluid increases: An evaporated fluid has to be treated as a compressible
gas, and, heated further, the
gas becomes
ionized, becoming a «plasma» of positively and negatively charged particles that interact collectively via electric and magnetic fields.
Achieving fusion — nuclear reactions that have the potential to produce copious, clean energy — requires heating hydrogen fuel to
more than 100 million degrees Celsius, causing it to become an
ionized gas or plasma.
In the 60 hours he spent bombarding metal foils with X-rays — creating analogs to stellar plasma, or
ionized gas — Wark pulled
more data than he had from any single experiment in a quarter century.
The Little Ghost (right) is a
more classic planetary nebula: Its doughnut is the steadily expanding ring of star
gas that has been
ionized and set aglow by ultraviolet light from the central white dwarf.
As
more stars and galaxies formed,

ionized.
The «Local Bubble» of low - density, hot and
ionized gas, is actually part of a tube - like chimney that extends through the local region of the spiral disk into the surrounding galactic halo, and so may can act as a vent for the energetic hot
gas produced by supernovae (
