A common, matter-efficient science-fiction habitat is a hollow cylinder or ring in space that is spun to simulate the pull of gravity on its interior surface. These habitats have been imagined as ...

There exist numerous theories on why the Moon lacks a layer of air if any, however the main culprits are gravity and the lack of Geo-dynamo simply put the Moon does not have the necessary mass nor the ...

(My world's details) I have a super-earth world. The surface of the world is shallower due to extra gravity, so shorter mountain ranges and fewer ocean depths. The world orbits a binary star system at ...

I realize that many factors affect this answer so assume the following: Star type: G2 star (like our Sun) Composition: O2, N2, CO2, H2O atmosphere Magnetic field: Two different magnetic field ...

A common, matter-efficient science-fiction habitat is a hollow cylinder or ring in space that is spun to simulate the pull of gravity on its interior surface. These habitats have been imagined as ...

Is it unreasonable to suspend one's disbelief that an asteroid belt naturally formed with enough mass distributed through the belt to justify the formation of a belt-wide atmosphere given the ...

I have a super-earth world. The surface of the world is shallower due to extra gravity, so shorter mountain ranges and less ocean depths. The world orbits a binary star system at a distance of the ...

Imagine a universe where the space is not empty (or almost empty) but somehow it's full of water or other liquid. How could planets still have an inhabitable atmosphere? What could make this "air ...

If a planet were to have a very thin atmosphere how thick or thin would it have to be to allow there to be a daytime and a nighttime given human or near human ocular sensitivity? In other words, ...

Suppose we had an Earth-like planet based on Saturn's moon Iapetus. Iapetus has an equatorial ridge, 13 km high, which runs around it. Scaling that up to an Earth-sized planet, it would have a ridge ...

My story takes place on an Earth-like, inhabited world that is far larger than Earth, has roughly 110% of Earth's gravity, and has unusually high (and generally unexplained) EM emissions permeating ...

On a spaceship with a total loss of power, say for instance, because of a system failure or something, what would happen to the people aboard? Would they become hypoxic? And would it get warmer or ...

I am working on a story. i want to know if is it possible for creatures like snake, eagle, vulture to stay on an altostratus cloud without falling down. if possible the limits on how much force and ...

Using Artefaxian's excellent spreadsheet I have created a basic idea for my planet, but in the 'Stability Checker' part my low gravity planet is unable to hold H2O. I am wondering if it is possible ...

Picture a band of happy campers, literal campers, sitting around some fires. Suddenly they feel their inner-ear "filling up" and after mere instants the ears begin popping, as if they were inside a ...

For sentient avians, knowing the location and behavior of currents in the air would be vitally important. Jet streams, thermals, downdrafts, and shear layers would all be important in their daily ...

Rockets consume a lot of fuel and carry not eough payload. To reduce the fuel needed, why not send it in the mesosphere? Imagine a big balloon, capable of carrying a small rocket to the mesosphere (...

Rockets are heavy because they need to transport the fuel as well as the oxidizer agent. For example, the hydrogen is the fuel and the oxygen is the oxidizer. The problem is it makes the rocket heavy. ...

35% O2 (oxygen) 61% Ar (argon) 1.07% CO2 (carbon dioxide) 0.93% As arsenic 2% Other trace elements On an exoplanet with a mass of 0.284 Earths and a surface gravity of .66 gs (6.44 m/s^2), would this ...

So my question is pretty much as the title states, what would be the effects on the human body with these atmospheric conditions? More specifically, how would effect the growth of land mammals, ...

Im busy wrtiting a Space Opera and was going to utilise the "hypothesis", or whatever you call it of an ancient civ mining gold here and utilising it to disperse into its atmosphere, in turn either ...

Piggybacking on this question: Could soft matter infused with nano or pico sized magnets be used to clump together so that we could create environments with it? ...So we have a planet that has lower ...

An abandoned outpost from a long extinct race is discovered. It can easily be repaired and would make an ideal location for a colony, however it has been breached and any usable air has been long ...

I've been trying to create a Earth-like planet but I'm not sure if my planet's atmosphere is breathable. (It's mostly the amount of helium I'm worried about). I've tried to make it Earth-like while ...

If one had three humanly habitable planets with the same gravity but different atmospheric densities due to composition, namely Earth, one with a denser atmosphere (about 1.5x as dense) one with a ...

Is it possible to have an atmosphere that is essentially fog, but still be breathable by humans? I'm basically looking to have an environment where visibility is very low (for suspense reasons) even ...

The Leidenfrost effect is a physical phenomenon in which a liquid, in near contact with a mass significantly hotter than the liquid's boiling point, produces an insulating vapor layer keeping that ...

How dense would an atmosphere (that's presumably non-toxic) need to be in order for a human being (without wings, artificial or otherwise) to achieve unassisted flight (without killing said person ...

If the water on earth were displaced to surround the earth in the atmosphere to create a water canopy, how thick would that canopy be? I apologize I should have been more specific in my original ...

The second terrestrial planet orbiting the Sun is shrouded in greenhouse gases, the entire surface of Venus is always scorching hot due to the high concentration of atmospheric carbon dioxide which ...

I want to have an Earth-sized planet (with similar gravity) with an extremely low-density atmosphere (comparable to Mars) at most of its surface. Complex life, including an information-age ...

I'm working on a planet containing an atmosphere composed mainly of sulfur dioxide, with, notably, only trace amounts (if any) of oxygen. Is such a planet one that could realistically pop up in our ...
