Four small holes in the dome allow the neutral gas to stream into the chambers.

This, in turn, reveals just how much neutral gas, mostly hydrogen, there is.

Although the tunnel lacks much neutral gas, he says, it may contain some ionised gas.

Regions devoid of neutral gas are vital for astronomers who hope to observe stars at extreme ultraviolet wavelengths.

This filament may be part of a shell of neutral gas that surrounds the hot bubble.

A stellar wind is a flow of neutral or charged gas ejected from the upper atmosphere of a star.

Fusion plasmas are typically generated from ionization of a neutral gas.

The handkerchief is before me now, under a glass dome filled with a neutral gas that will preserve its fabric intact for eternity.

The ions move with the neutral gas making the conductivity isotropic.

Atmospheric waves dissipate above this level because of collisions between the neutral gas and the ionospheric plasma.
