Can you breathe in space?
Outer space is a vacuum. You cannot breathe in a vacuum because there’s literally no air to breathe, and if you tried, you’d be dead in about four minutes. Also, because space is extremely cold, your eyeballs could freeze solid, and even if you somehow survived, you’d be blind.

They could be kilometers in scale. You wouldn’t even need hydrogen or helium. Because the atmosphere of Venus is mostly carbon dioxide, oxygen and nitrogen — ordinary breathable air — would float. The air that’s holding you up is also the air that you can breathe.

If Mars possessed an Earth-like biosphere in the past, Mars may contain subsurface deposits of oil and natural gas indicating past life. Subsurface oil and natural gas on Mars would probably cause seepage of hydrocarbon gases such as methane at favorable locations on the Martian surface.
