Question	—	Animals able to use atmosphere for biological chemiluminescence possible? Here's the scenario: animals on a world with an atmosphere with a significant amount of a certain gas is able to store "air" into a transparent growth (like a crest) and, with an electrical chord in the "crest", makes a glowing light with different colors depending on what's produced in the crest. Th... (more)	—	over 8 years ago
Question	—	What would a planet with little to no greenhouse gases be like? Say if a planet had either no greenhouse gases or a small percentage of a certain greenhouse gas (roughly 5% or less) in its atmosphere, but all other elements in the atmosphere could support life. What would be the effects of this certain type of atmosphere on the planet and biota (if organisms coul... (more)	—	over 8 years ago
Question	—	Could a planet with three-quater earth gravity and neon-/argon-based atmosphere exist, and what would life do with it? I'm creating a world three-quarters the gravity of Earth, and the composition of the atmosphere are as followed: 74% Neon (or Argon) 18% Nitrogen 5% Oxygen 1.6% Carbon Dioxide 0.9% Water Vapor 0.5% Trace The questions I have in mind are: Would Neon or Argon work better for this planet? Could... (more)	—	over 8 years ago
Question	—	Could an atmosphere of neon, oxygen and carbon dioxide support life, and what kind of life could it support? Could a planet with an atmosphere composed mostly of neon, with oxygen and carbon dioxide making most of the rest, support life as we know it (specifically on a low gravity planet)? If so, what impact would it have on the biota of the world? (more)	—	over 8 years ago
