They all have matter.
Glowing hot gasses
Aurora
A star
lava
Flames are the gasses of combustion, heated to the point of glowing. Hot gasses, being less dense and therefore lighter than cold gasses (surrounding air) rise upward until they are redirected by some solid object.
The gasses in the sun are very hot and therefore glow; the specific wavelengths of light that they emit are characteristic of specific elements.

They are both natural gasses
The answer will depend on what characteristic of the gases you wish to measure: the composition, pressure, temperature, etc.
Hydrogen and Helium
green house gasses are produced like carbon dioxide which is the most common one produced by cars
