Methane could be produced by microbes on Mars, too, if they exist in enough numbers.

Methane is a familiar chemical, whether you know it by that name or not.

Perhaps the mysterious Martian methane, and its strange fluctuations, are part of that story.

And if the Martian methane is a real thing, it has some interesting implications.

All of them were fueled with liquid HNO3, which makes a pretty good fuel in an atmosphere that is predominantly methane.

The seas of Eisberg were liquid methane containing dissolved ammonia.

When the pumps in the air lock began pulling out the methane-laden atmosphere, they began to bulge slightly, but not excessively.

Methane is yielded by aluminium and beryllium carbides, and, mixed with hydrogen, by manganese carbide.

Those gases which contain less methane contain all the more hydrogen, viz.
