Just thinking if it is possible to have a Fire-Freeze Planet? A planet with permanent Ice cover on one hemisphere while a hot terrain on the other side of it. A planet that may have moder...
This is a follow-up to an earlier question. My intent here is to work out the details, and explore the potential consequences, of one of the many excellent answers I received. Relevant questions ha...
Lets suppose that Antarctica at some point lost most of its ice (due to global warming or some other plausible reason) and now most of its bedrock surface is exposed. Compared to other continents,...
It would preferably be something that will either last a fairly long time fifteen to twenty years perhaps, periodically and last at least some months between or last indefinitely. I do not require ...
I am writing a science fiction movie script and a planet idea came to me a few weeks ago: A planet with equatorial icecaps and polar jungles. As interesting and intriguing as this is to think about...
I read somewhere that the size of a planet can influence the number of pressure belts (the areas of high and low pressure that cycle wind, heat and moisture about the globe) How would you go about...
A few years from now, say 2025 or thereabouts, a technologically advanced alien civilization discovers our solar system. They study us for over a year, using small drones that launch from a vessel ...
Going off of this question, What would happen to the Earth if Gravity disappeared?, if an area of 1,000,000 cubic miles (as in, at the epicenter the area of effect will reach into the earth 50 mile...
I am trying to figure out the climate on my planet. If there is an asteroid ring around the equator will it cool down the equator? And if it does cool down will the planet still be habitable? My ...
I understand this is a broad topic that to a degree was answered in previous questions. What I'm trying to do is to create a plugin in Unreal 4. I'll start by creating a day/night system and a sk...
This question is not a duplicate of this question. They're similar, but this one has one very large difference: only a large area has permanent cloud cover, not the whole planet. If low clouds or...
I am trying to create a planet for a fantasy role-playing game where the equator is an impassible region of ice. Ideally, I want to find a science-based solution to this and not have to resort to ...
A Milankovitch cycle is defined in Universe Today as a cyclical movement related to the Earth's orbit around the Sun. There are three elements to a Milankovitch cycle that affects the amount ...
Currently, Earth's eccentricity (orbital shape) is 0.0167086. Zero is a perfect circle whereas One is parabolic escape orbit and any greater becomes a hyperbola. And in the theory of the Milankov...
What I'm doing is trying to find a way to create an atmospheric cold trap that will maintain a temperature of approximately −200 degrees Celsius (−328 Fahrenheit). According to Wikipedia In as...
Is it possible for an earth analog planet* to have more than 3 convection cells per hemisphere? In our system we only have Jupiter and Saturn with 20 atmospheric bands, even Uranus and Neptune hav...
I'm currently creating a world with a population of about 4.5 billion people and 21st century technology. In fact, the world is strikingly similar to ours. Oh, except the islands that is. The en...
I'm building a small, naturally inhabited world where usable water is scarce or difficult to access. Is it possible to have a planet with groundwater, ice caps, temporary rivers and lakes, seasonal...
Assuming the world in question to be of similar size to ours, same proportion of atmosphere etc. but whose surface is perfectly flat, and has a 0 degree axle tilt what sort of weather/wind current ...
First, for scale, this map is about the size of the continental US. Assume that the mountains are about the size of the Rockies. These mountains are jagged on the outer edge, and more sloping on th...
Could a Snowball Earth drive our species into total extinction? The most obvious problem is: How would we grow food to sustain any grouping of people?
My Kepler Bb world has in total 8 seasons. 4 of those are transition phases. Their year begins on the first day of spring and their months with 9 day weeks are 65 days long. But that is just in Kep...
Our planet's best line of defense against the worst of the sun is the ozone layer. It is no thicker than 0.01 millimeters. It absorbs 97 to 99% of the sun's medium UV light (200-315 nanometers). ...
Is there any feasible way to create a long-term sustainable habitat on the sun? My target region for habitation is the temperature minimum at the bottom of the solar atmosphere. Metals would have ...
This is sort of on the more realistic side of worldbuilding, but maybe somewhat exaggerated for the sake of a setting. What's the fastest atmospheric pressure drop in weather records? This questi...
Inspired by this question, suppose that the Earth decided to move its orbit much further out to reduce the effects of, say, global warming or the effects of a dying sun (or far enough to make this ...
I am writing a story where a freak magical accident causes a fully-formed landmass to pop into existence like it was there all along. For the purposes of this question, let's assume: the contine...
I had the idea to make an artificially constructed planet which is terrestrial, but has the diameter of Jupiter. Instead of being a solid sphere, it would be five spherical layers, with land on the...
If the ozone layer of planet Earth was completely depleted (to near-zero concentrations), what would the average summer UV-index rise to in New York City? If relevant, other changes anticipated ar...
We see plenty of seasonal variation on Earth, due to the large axial tilt, but the Earth follows an almost perfectly circular orbit, so we don't get much variation as a result of that. What if we ...
The village background: It is located at an elevation of 2,119 m (about 6,952 feet) above sea level with a population of about 1,800. It has a continental climate with Oceanic influence. Summers ...
I am working on a project (The Longest Day), and I'm sure some people here have the necessary knowledge to give me some more usefull info. OK, here it is: Lets say that Earth's spinning speed dim...
I am imagining a temperate forested area with freshwater lakes, rivers, small mountains, and rolling grassy hills. This environment is situated within a very large explosion crater. Outside this cr...
The conclusion of my question Is it possible to have a planet unsuitable for agriculture? was that the most plausible reason for preventing agriculture from developing (beside nomadic herding) was ...
NASA received a telegram from the direction of Proxima Centauri stating that the abominable snowman are coming for a visit and they expect snow to fall everywhere even along the equator. They also ...
Suppose the chemical reaction: $$3CO_2+2H_2\rightarrow 2H_2O+2O_2+3C$$ This reaction could be used to filter out $CO_2$ from the atmosphere, slowing down or reversing climate change. The solar syst...
Consider a world in which instead of light coming from a single region of the sky, the sky appears close to uniformly luminescent. The intensity of this light depends on latitude such that amount ...
I have planet with twice the radius of Earth, with its core being the same absolute size as Earth's in order to provide magnetosphere, and the rest of the planet made of silicates like Earth's mant...
Let's say I have a world that contains magical fire and ice creatures. These creatures can utilize magical beams of energy that ignite or freeze the things around them, though doing so on more than...
Farmers use dry ice(CO2) to seed the cloud on Earth, can we do the same for Mars? The acidity doesn't matter it can be any element or compound as long as we can recognize it as precipitation, as us...
The Idea is to move large amounts of water vapor high into the Troposphere, thereby blocking some of the sun's intensity. Factors that contribute the Earth's solar heat gain include reflectivity/e...
This question concerns this Alternative Earth. To make a certain fictional country which occupies the northern part of Russia more interesting, I want to make agriculture feasible in Siberia and t...
Earth like planet has 3 atm pressure at it sea level. How would it affect its rainfall system? 1) Using internet calculator I got a result that boiling point for water would be 131°C, while freez...
How would just the weather be affected if there was huge mountain range between the Arctic and the mid latitudes of a planet? Roughly 50-60 degrees latitude. A little further south than Earth's Arc...
I have just found out that the Milankovitch Cycle, a machination responsible for the creation of the Pleistocene ice ages, has its part played partly by orbit from the entire solar system. As a re...
I am currently at the end of my wits. No matter what change I do to the North American geography, northeastern Nebraska (42.4649° North, 96.4131° West), is still in the danger zone called Tornad...
This is the map of our Permian from 300 to 252 million years ago: As you can see, (nearly) all of the continents had joined together to create one massive landmass called Pangaea. To the sharp ...
Sea levels are rising due to global warming. The Moon brings tides that also rise the sea level. If we destroyed the moon could this problem be solved? Would it have other consequences?
I'm a newbie here and I'm slowly building a story based on Ancient Egyptian mythos that revolves around a primarily solar powered city in a vast desert. There will be magic and Gods involved, but I...
If so, what's the equation (or series of equations) for this, and what variables do I need to take into account? EDIT: the planet in my setting is rather "chilly" (around 9.35 Celsius average) wit...
