A human crew of 6 has been sent on mission to Mars The lowest energy transfer to Mars is a Hohmann transfer orbit, which would involve an approximately 9 month travel time from Earth to Mars, a...
For an in-situ born planet, it can happen, though it is hard to have the exact chain of events. Basically you need to have a series of gravitational slingshots with a larger body that put your pla...
Space bodies like planets, asteroids and comets are formed by the remaining materials of stars explosions. Therefore they are usually made up of several elements. There is the possibility that a p...
Space explorers have landed on an Earth like planet and, to their surprise, the place is luscious and covered in life, to the point of resembling some earthly tropical atoll. What they don't know ...
An old saying goes that if you have an army, it will want to fight a war. That seems to be true also for our personal army, our immune system: there seems to be various pieces of evidence that man...
Permanent ice caps are formed when the rate at which water falling under the form of snow is higher than the rate at which the water is removed from a certain region either by evaporation or outflo...
On an alternative Earth live the people of Tcelonia. One of their founding myths goes that, in the dawn of times, when they were under the menace of being attacked by an enemy population, for an e...

This species of humanoids has a peculiar way of reproducing. Instead of the usual physical intercourse between a male and a female, followed by the sperm cell merging with the egg cell to generat...
For us earthlings, the concept of "year" came from the observation that the Sun reaches a minimum and a maximum span in the rise-set path in the sky. On a planet experiencing extreme perihelion p...
Halite, or rock salt, is a rock formed by salt deposited in past and then undergone geological processes. My question is: provided that enough (how to get that much sugar is not in scope of this q...
After traveling a long long time, your spaceship is finally entering into the gravitational sphere of influence of a Sun-like star. Your captain would now like to move from the Oort-like cloud dist...
When it comes to processing hearing and visual signals, our brain has different capabilities. While it seems to be able to execute a spectral analysis for sounds, so that when we hear the superpos...
This plant I am designing grows on earth, in locations where competition between plants is fierce, water is scarce and also nutrients in the soil are diluted. The dilution requires the plant roots ...
There are reports of blind people being able to develop an echolocation ability, by listening to the echo of sounds emitted by them. Since this ability is pretty handy for spies and soldiers, the ...
There is an earth like planet, with similar mass, gravity, atmosphere and magnetic field. The main difference with earth is that it has a highly eccentric orbit (eccentricity 0.8). Let's say that ...
This human population developed in a mild climate region, with fair abundance of food, water and shelter. However, though they have the skills and the means to explore forth, the population is unab...
Coriolis' force is the cause for winds and water streams to bend while they travel North-South along the Earth surface. This force is inversely proportional to the rotation speed of the planet: the...
Planet Swamp. As the name suggest, it is a planet fully covered with swamps. A new kind of carnivorous plant has been discovered on this planet: when its leaves are touched by an animal or moved b...
Location: an interstellar gas cloud Situation: an alien family stops for about half an Earth hour in the middle of the cloud to have a snack along their trip (by stops I mean they get null relati...
In its wandering through the Milky Way, the solar system is getting close to a solitary neutron star. The neutron star will "fly by" above the plane of the ecliptic and its closest distance from th...
Pathogen virus work in a simple way: they inoculate their genes (DNA or RNA) in the host cells and let them replicate huge amounts of the attacker while hampering the host vital functions. As react...
I am designing a mammal living in a warm environment (like a warm desert) which has developed a switchable metabolism, so that during the day it is cold blooded and during the night (when it is col...
