I would like to create a civilisation that develops near active volcanos. In ancient times, they would make good use of volcanoes like: Use lava as heat resource. Use lava as material to make bri...
Consider an Earth like planet is orbiting around a Sun like star, it is almost identical to our Solar system, except the orbital inclination of the planet is 90 degree to the equator of the star (n...
I was imaging a system which has a black hole, a star and Earth like planet. The star and planet orbits around the black hole, but the planet has same orbital period as the star, which is a "quasi ...
I want to have two planets orbiting each other, and there is a ring around both of them, is this possible? I know rings are formed inside the Roche limit, so if the ring lies outside the planets, ...
I'm imagining if we can live on a very special white dwarf which has very special characteristics: It has cooled down to a very low temperature Its rotational speed on the equator can almost canc...
Would it be possible for a gas giant to have differently colored hemispheres? E.g. the northern hemisphere appearing blue when looked at, while the southern hemisphere would appear brown? (or any ...
I have an idea: can a moon float on the atmosphere of a gas giant, just like a piece of wood floats on the water? It is based on the following situation: The density of the atmosphere increases ...
I'm imagining a situation that we can see a star change color periodically: A star and Earth orbit around a black hole The star is very near to the black hole so that it has high orbital speed, w...
Suppose there is a rogue planet. I was imaging what could be its energy source for life, and I remembered that photos of the center of a Galaxy look very bright. So my question is, can a galactic c...
I'm trying to construct a habitable world which has a sun orbiting around it. I know a star can't orbit around a planet, because a star is much more massive than a single planet, which has been kno...
