（单词翻译）

 One day these manned space missions may reach out even further to distant planets with alien atmospheres, atmospheres that may support their own life forms.

Else where in our universe on distant planets, alien air may support extraterrestrial life. Joel Hagen has spent 20 years imagining how those atmospheres could have affected1 their inhabitants.
That's where some of the real creative joy comes from, trying to think about everything that has happened here and then take yourself one notch2 beyond and imagine what haven't i seen here, and then try to visualize3 that.
One of the possibilities that intrigues4 Hagen is life on a gas giant planet.
This is an environment so completely alien to what we are used to, even a planet like Jupitor for instance has no solid surface, just a gradual transition of density5 of gas, and i think we might imagine creatures in an atmosphere like that that sort of rely on buoyancy, perhaps being able to generate hydrogen for example somehow within their body.
These creatures would be like hydrogen filled blimps, lighter6 than the air, able to float amongst the gas clouds.
The concept that i have here is to have perhaps colonies of microbes in the sort of tentacle7 like structures here, and these microbes generate the hydrogen which in turn sort of inflates8 the gas bag here, creature like this then can  sort of float freely...
