For backgrounds sake, let's say that there are large, and I mean large beings living underneath the icy surface of Europa. Now consider this excerpt from NASA's page on Europa: One of the most...
As far as I know stars are going supernova as a natural process. Can aliens trigger it artificially? If this is possible then: How can I do this (what minimum technology and civilization develop...
I came up with a pretty creative idea: An alien life form having an organ near to the brain that translates information out of the blood stream into feelings. My questions: The medium of communi...
So this question is about a humanoid species I was thinking of: They are semi-immortal and live long life spans, which poses the problem of not having enough space for new memories after a long t...
So far, we see an alien life form depicted based on earth type of animal kingdom, we see an insect like Zerg, a humanoid grey alien, etc. However sometimes we see alien like Guardians of galaxy's ...
Usually, forms of life are associated with organisms like humans, plants and animals. The probability that such can evolve in an environment is very low due to the many constraints that have to be ...
I'm making a species that turns the outer layers of its skin to stone, for defense purposes. It'll also have eyes that glow yellow, due to ingesting sodium vapor or helium. Is there some way to com...
I am designing an alien civilization for a story, and I am currently in the biological part. They will be oxygen breathers, so they will need to have that oxygen delivered inside their bodies, and ...
Before we begin, two things. This question was inspired by this one. I definitely don't want this to happen. So, I have two very close tidally locked planets, each fills up about 2/3 of the sky of...
It's the height of humanity's space-colonization golden age when casual interplanetary travel has become possible and humans have either colonized or established large space stations around nearly ...
Could an ancient civilisation create plastics on Saturn's moon - Titan? Much like how we forged metals and glass here on Earth... To prevent it from being impossible from the start fire can be pr...
Zerg Overlords are flying alien creatures that aid their broods by managing lesser members of the swarm, transporting units within their carapaces, and alerting a hive about any danger they perceiv...
The title says it all. How would one go about creating a planet with aliens that have medieval grade technology (windmills and carts and stuff.) No high level technology. However, I want the aliens...
Imagine that, in the near future, pollution, overpopulation and war leads to a massive extinction where almost all chordates, some invertebrates and many plants are wiped out. Small, resilient plan...
My reptilian aliens that lactate become adults at 20 years old. I might add a graph here of proposed shedding rates over time and maybe even a separate graph for growth. But here is what I am prop...
If a Kardashev Type III alien civilization wanted to monitor the earth (and its inhabitants' progress) via a satellite/orbiting object, how would they realistically transmit data from this object? ...
On an hot planet at the wooded poles are two aliens species that coexist in a mutually beneficial relationship. The Honey Mouths use gecko-like feet to hang from the far larger Thorn Shredders, wh...
This question assumes that there is complex, intelligent life on some other world other than the kind found on Earth. Carl Sagan allowed that silicon and germanium might replace carbon, and ammon...
I have done research on blood and in particular the component adding color and transferring oxygen. Hemocyanin is directly dissolved into the blood. This works for an octopus, but not a reptilian ...
I'm creating a planet inhabited by beings who have a body temperature that is colder than humans. What conditions on the planet would require them to have evolved this trait? Thanks
The platypus do it, so it can and is done, some how. It would be a waste of energy to be lactating the entire time after the egg is laid up until it hatches, so how does my alien race know when to ...
We know that the inner and outer core of our planet is made up of heavy, valuable metals in high concentrations. So, what if a technologically advanced, space-faring civilization wanted to mine tho...
The core of this question is this: Given what we believe we know about the requirements for a tool-using, space-faring race to evolve, how viable would a species that has a hybrid exo/endoskeleton ...
In my world an alien creature claims to be from an earth-like planet orbiting a 500 light-years away solar analog star. It tells us that the planet has x mass, y diameter, z orbital period, that sp...
I am working on an alien species with mammal-like features and characterized by radial symmetry, in opposition to bilateral. They have four lower limbs arranged in a square-like disposition, with t...
Quick sketch of how I conceptualize this creature's skeleton. Sorry for the chopped off head, the jaw design and such isn't finished. The 4 yellow bones on the tip of the neck are the base of the...
About 200 years from now, a human scientific expedition, lead by a international coalition of Earth nations, is sent to an alien moon around a habitable planet, light years from earth. Like it's pa...
I need a reason for two antagonistic humanoid lifeforms living on the same planet to be completely incapable of direct physical contact. I don't mean they have a strong aversion to it, I mean the...
The inspiration came from the music in the title sequence of the film Alien. The idea is a planet that humans have colonized where it's almost always drizzling slightly. It's always dark but there...
In my story, a team of scientists are sent to an alien world similar to Earth to conduct general research on its environment, ecosystem (that is: its animal- and plant-life), and weather. It is the...
I was wondering what kind of planet would lead to aliens being significantly larger and stronger than humans. From my understanding, a planet with lighter gravity would lead to larger creatures, b...
This is my first post here, but here we go: I have been creating an alien world for a while, and the sentient species on it is very canine-like. They have a canine body, legs, and head, and the on...
This scenario requires an alien creature with a decent chance of defeating a modern armor in a brief combat. This alien should be: At least as large as a horse, but not much larger than a semi-tr...
Imagine a tidally locked planet that revolves around the star at just the right distance that a habitable zone can be formed in between the scorching desert side of the planet and an icy desert sid...
Imagine alien prospector wanting to build "space highway" through our solar system. There could be another route, but the one leading to our system is "the best" Such prospector also wants to use ...
I have read questions such as these two about aliens adapted to environments with high atmospheric pressure experiencing negative effects when exposed to Earth's comparatively low atmospheric press...
Imagine a child of mixed race, one parent is human and one is an alien who has some ability humans do not have, for the sake of argument telepathy. I'm assuming there is some advanced medical assis...
In a solar system much like ours, would there be the possibility of a planet of our size that would have lakes, rivers, oceans, etc. that would be composed of either a mixture of water and ammonia ...
Because vanadium dioxide experiences a sudden phase change at 67° C, instead of trying to make small changes to gradually contract or expand muscles, could an alien instead have many smaller muscle...
The older man looked at the younger one. He took a deep breath and began to tell his tale, just like he was told before when he himself was that young. I've been here way longer than you, let m...
Because I need a spine that works for massive and small creatures I'm thinking of making a plant-based spine (which has its own DNA). The spine acts kind of like a cucumber, in that when it sucks u...
I'm thinking of making a species that evolved in a planet that has a type of algae that secretes a nutrient rich sludge that the species only has to drink to survive. I know that this would make th...
Given ample access to uranium and a race that is naturally resistant to radiation poisoning, how soon could a civilization invent nuclear reactors?
I've heard that the atmospheric pressure on venus is 90 times that of earth, but I don't know the melting point of $SiO_2$ at 90 atm nor at what temperature its vapor pressure hits 90 atm. Basicall...
So Vanadium is present in fossil fuel reserves, and in present in some organics on earth, I figure that if a planet was rich enough in Vanadium a species could ingest it, then the vanadium could be...
So our muscles run off of oxygen, but I heard from my brother when posing this question (he's a bio major in college) that using phosphorus instead of oxygen to power our muscles would make them fa...
I've been spending a lot of time developing aliens for a comic I'm working on, in the skeletal structure department I've run into a bit of a roadblock, how to design a spine for a species that is k...
This is possibly not quite the right place to ask this question but it's fundamental to the world I'm working on so here it is; if faced with a potent existential threat, in the form of an outside ...
Premise Let me begin by citing the intellectually charged and equally comical banter between physicist Brian Cox and "Doctor Who": (aliens appear on console) Dr. Who: "That's a silent; yo...
Essentially all the members of an alien species live within a single relatively sparsely inhabited megacity. The city has a surface area of about 30,000km². The species happens to be almost exclu...
