Alien Environments

[@michaelpettersson4919]

I remember playing Elder Scrolls III Morrowind. The game are set on an volcanic island filled with strange lifeform. Gigantic mushrooms large as trees and alien creatures filling the wildlife, being used as beasts of burden by the locals, including "egg mining" where workers would go into the nests of giant insects to harvest eggs something only those that smelled right where allowed to do.

[@isaacarthurSFIA]

I remember that island, and given that it's been nearly 20 years since I played the game, it must have made an impression :)

[@jamielonsdale3018]

With enough plutonium, we can make mushrooms that dwarf the Burj Khalifa 😉😂

According to most casual sci-fi, most planets are earthlike and we don't even have to worry about alien pathogens when landing on them! So that pretty much settles it.

[@yjlom]

well, it'd be pretty unlikely for an alien pathogen to be able to infect us, incompatible biochemistry and all that

I believe I read an essay by Asimov where he considered molecules which are similarly simple as water. NH4, CO, CO2, CH4, C2H6, SiH4, etc. He concluded that H2O was ideal in that it allows a greater temperature and pressure range to remain liquid compared to any of the rest.

Small reminder that the solar eclipse on earth is probably a very rare event in the galaxy, and there's a good chance there will be a great deal of interstellar tourists. Come see it If you're tired of tourists right now, just imagine they don't even share the same planet as you

[@acaryadasa]

Then the aliens had better hurry up. With earth moon distance gradually growing (meaning a smaller apparent lunar diameter) and the sun gradually increasing in diameter (larger apparent solar diameter) we only have about 600 million years left of good solar eclipses left. Although on the other hand, if you have easily available space flight you can see a solar eclipse of any planet and its star anytime you want, if you don't mind a view from a space craft instead of from a planet.

[@2013Arcturus]

For a long time I've settled on the idea that any aliens and alien environments will APPEAR analogous to any of our systems we have, due simply to convergent evolution and physics. For creatures you are almost always going to have photon receptors, (eyes) chemical receptors, (noses) and electro/pressure sensors (touch) and flying, crawling and swimming. And you are always going to have deserts, forests, arctics and rivers and so on, and analogous lifeforms occupying niches for trees, cactus, lichen and algae.

[@brandonpersaud5634]

Don't forget that any intelligent aliens would have to evolve with creativity, curiosity, abstract thinking and also opposable appendages that are capable of manipulating objects in intricate and complex ways so that they can create early tools.

[@icecold9511]

Forests aren't a guarantee. Trees don't necessarily have to come along. One Fermi paradox answer is a lack of viable building material or early fuel.

Some of my favorite sci-fi stories and games are about being stranded on alien worlds. Like Pikmin, you are crashed on an alien world with a toxic atmosphere (for you) but filled with life. You have to put your ship back together within 30 days, before your air runs out, with the help of the local fauna. In one of the bad endings, you have to transform yourself into one of the local fauna in order to survive.

Excellent and interesting as always. I believe Roger Zelazny was only able to narrate most of the Amber Chronicles, and they got someone in who sounded somewhat like him for the last two or three books. You should check out Brian Stableford's Hooded Swan (Start Pilot Grainger) novels (Halcyon Drift, Raphsody in Black, etc) and his Daedalus Mission novels (The Florians, Critical Threshold, etc.). Both of these series explore alien worlds that are very interesting and engaging.

[@isaacarthurSFIA]

He did the abridged version for everything but Book 10, and unabridged I thought too but not sure if that was beyond book 5. I didn't care for the book 10 narrator, it felt like he was aiming for 'spooky', but I loved the ones Zelazny did and the music intro/outros on them. I've heard of Stableford and mostly positively, so I'll have to check him out

[@johnchance7836]

The alien environment I've been contemplating lately is simply earth without the great oxygenation and with microbial mats continuing forward. It seems that in that lower energy environment purple sulfuric bacteria could form lichens with fungi that break down rock and the lower, dead, layers of thick chemo-synthetic bacterial mats. A sulfur and methane environment also would be warmer and might produce more life forms that can thrive on thermal radiation as well. The interesting bit here is that the energy sources used would have a different chemical balance and use more energy sources . . . Solar, Thermal, and chemical being the dominant forces. Jaws, skeletons, and shells might take too much energy to be viable so you'd see less predation and more symbiotic relationships. Without jaws a predator is limited to eating things that are much smaller than the organism itself and that puts forth entirely different sets of evolutionary pressure. Successful organisms would be things like cells with mitochondria inside, bacterial mats that share energy and feed on each others waste products, lichens . . . and of course without oxygen degrading DNA there would be less reason for sexual reproduction and perhaps more benefit to earlier forms of gene sharing. The role of scavenger and even predator both might be filled by fungal mycelium of various types with networks trading resources below the surface, and sprouting out large lichen bodies as a hedge against scarcity.

As a spec evo thought experiment I came up with an eyeball planet where a constant firestorm at the planets day-pole keeps burning up all the oxygen in the atmoshpere, but there is still plenty in the planet's oceans in the twilight band and on the night side. That doesn't mean dry land and especially the scorched day side are lifeless though. A vast network of transparent lichen and plants with glass-like leaves create a constant stream of oxygen rich water deep into the dry breathless desert. Land dwelling creatures get the oxygen they need by sucking water from this lichen layer and storing it in their gill-bladder

[@BethKjos]

"Bio-forming" sounds like a great idea. Find or engineer some extremophile single-celled organism that can deal with the crazy conditions in Venus's upper atmosphere to sequester carbon and sulfur and maybe a few other nasties. With zero natural predators in the Venusian environment they might reproduce exponentially (at least until resources grow scarce in a few days). It's mad hubris of epic proportions to be sure, but you've got to start somewhere.

The Orion's Arm setting (a creative writing project, and a hard sci-fi transhumanist space opera with over 10 000 years of history, for those unfamiliar) has some truly bizarre aliens, and the first truly alien species (as opposed to long lost colony) that humanity's descendants run into are the To'ul'h, something like a mix of a starfish, an octopus and a headless flying squirrel, that evolved on the surface of a rather rare subtype of a Venus-type planet - one with a lot more water, which, due to the extreme pressures, is still a liquid despite being many times the boiling point on Earth. This is probably the most extreme environment I have ever seen a semi-plausable alien species evolve in, and it's presumably inspired by some paper on xenobiology. I'd say the chances are very slim, but it's an interesting possibility.

Residue of Ferme events in the order of 100,000+ super nova’s worth of energy each, linger from a sideways facing core blackhole…. How many civilizations could have come before us, only to have been purged by that sleeping giant in the center of the galaxy?

Combined with a continuous forest fire circling the planet annually for geologically/ecologically/evolutionary relevant periods of time caused by very strongly prevailing winds or mega-hurricanes spinning in opposite directions in each hemisphere. I've also been fascinated with the idea of two branches of life with different chirality for each braches' proteins successfully competing despite organisms from each branch being practically chemically unable to interact with each other.

here's a recent Idea I've had for an alien environment: What if there were a gas giant or brown dwarf in the interstellar void or the outer fringe of a star system with a moon or planet subjected to tidal heating similar to Io. Now say the moon or planet is massive enough to hold an atmosphere and also receives enough energy from tidal heating to have Earth like surface temperatures. The amount of tidal heating necessary would depend on the thickness of the world's atmosphere and its ability to trap heat, so there would be a range of parameters that would produce such a world. Furthermore, a world like this would have the same advantages of an ice shell moon in that its habitability would not depend on its placement within a star's habitable zone. As for the environment itself, the intense tidal heating would result in extreme levels of volcanism on the surface, so there could be lakes and rivers of molten lava alongside bodies of liquid water. The atmosphere would likely consist mostly of volcanic gases, so you would wear a breathing apparatus before going into a lightsaber duel instead of after you almost burn to death from not having the high ground. Moving back to serious discussion, though, I imagine the would would be completely covered in cloud layers since the volcanic gases of its atmosphere would freeze out at different altitudes with little or no light energy reaching the world from the outside. One thing I find interesting about this hypothetical world is that it's probably the only place that could be called a "hell world" where a person could theoretically step foot on the surface wearing nothing but a breathing mask. Any life on such a world would probably rely on chemosynthesis like the ecosystems found at deep sea hydrothermal vents on Earth. An oxygenic analogue to photosynthesis that exploits thermal gradients, if possible, could also allow for complex life on such a world. As a caveat, however, I can see how the abundance of carbon dioxide in the world's atmosphere from volcanic emissions could cause the lightning suppression problem Isaac mentioned in the video.
