Die Planeten um den Stern von Teegarden haben eine Mindestmasse von 1,05 bzw. In fact, this is the case for most the large moons in the Solar System. Teegarden c has only … Assume that sort of thing exists outside of this project's spotlight, which I'll tend to focus on charismatic fauna & flora. However, tidally locked planets in the HZ of late M-dwarfs are known to have additional challenges on their way to become truly habitable planets. Hi, we understand that enjoy and Ad-free experience while surfing the internet, however, many sites, including ours, depend on ads to continue operating and producing the content you are reading now. The outermost planet Teegarden c only has a 3% chance of having a temperate surface environment. Most thermidorian lifeforms are capable of deriving energy from thermal gradients (though this energy is minuscule compared to photosynthesis). Like Diaphania, the kingdom Tomatrichia contains branches that on Earth would be distinct as Animalia, Plantae, and Fungi. All bets are off. The variety of forms life has taken past and present, and the processes that gave rise to those forms, are really fucking cool. Air and water. It is as if a rod connects two points on their surface. Hunters & Highwaymen: 30 NPCs + Story Hooks for Taverns, Highways, and the Deep, Dark Woods, They Did a Mario Kart: Maximum Recursion Depth Play Reports Catch-Up, Speeding Up Five-Sentence Character Creation. Proxima Centauri b is the closest exoplanet to Earth. Beneath this they've got a muscular digging "foot" lined with lateral spines or bristles, and their "head" bears jointed opercula and a bouquet of feeding/sensory tendrils. I've got some out there ideas for the directions TSB will take, but ultimately it's very close to Earth in terms of global conditions. Teegarden b should be tidally locked and could even be devoid of an atmosphere or water depending on its thermal evolution. A natural extension of my interest in real forms of life then is speculative evolution, using what we know about biochemistry, evolutionary pressures, and the like to better imagine how life might develop on other planets (or alternate branches of our own planet's history) in a more-or-less plausible fashion. Tau Boötis, an unusual example, a star might be tidal locked by it's planet Tau Boötis b. Speculative Evolution: Teegarden's Star B - Part I... Swords & Stitchery - Old Time Sewing & Table Top Rpg Blog, Quick Commentary on The Hostile rpg by Paul Elliott from Zozer Games For The Cepheus Engine & The Classic Traveller rpg, Seven futile artistic plans occasioned by various periods of holiday with vastly insufficient time to contain them, [Dungeon] Maze of Amazement ( & Death ), one-page adventure for OD&D/Delving Deeper, Double Troll Commission: d6 Troll Shinies & d6 Troll Lairs. This project will be loosely based on the planet Teegarden's Star B, a recently discovered exoplanet with one of the highest Earth Similarity Index Scores of any known exoplanet thus far. Everything else from here on out is my own invention. This results in a bizarre phenomenon where the moon Charon would always be in the same place in Pluto’s night sky. Add an answer or comment. Koubanites: One of the truly rare heterotrophic thermidorian clades, containing both mobile and sessile predatory and filter-feeding species. Which of the following statements regarding the moon and Earth is correct?A. It's just a difficult thing to even conceive of, with or without good science, let alone explain coherently and make into a game or narrative.All of that said, that's exactly why I find it so interesting ;). That is why we only see one side of the Moon. There's analogues to viruses and bacteria and all that too, but I'd find coming up with that stuff boring. I'm really interested to see where this goes.You've mentioned the idea of plastic-like organisms before so I'm glad to see that come into play here.Even besides just understanding the science on some level, another thing that I think can make speculative evolution interesting but also difficult, is where it heavily diverges from anything we have any frame of reference for. There's universal constraints like the square cube law and so on (we're probably not going to see macroscopic animals that fly using lighter-than-air gas), and some features that have evolved independently so many times on Earth that we'd probably see them in alien life (e.g. It has a smaller axial tilt than Earth (leading to less differentiated seasons) and rotates in such a way that gives it a 40-hour day/night cycle. If they’re confirmed, both of the newly spotted worlds are nearly identical to Earth in mass, and both planets are in orbits that could allow liquid water to trickle and puddle on their surfaces. There are no comments. Unlike sea urchins they lack tube feet and an Aristotle's lantern, while their spines are articulated and can be bent to serve as legs. This is known as synchronous rotation: the tidally locked body takes just as long to rotate around its own axis as it does to revolve around its partner. They calculated that atmospheres between one-third that of Earth's or as much as 17 times as dense would allow for liquid water to exist on the surface of either planet. Eventually the fruiting body was adapted from a temporary reproductive measure into the main body of the creature, with the mycelium serving only to stick it in place. eyes, venom). When we see our moon, we only see one hemisphere—the “near side”; the lunar “far side” is never in view. Perhaps in defiance of God and astrophysics, I'm going to say that my TSB is not tidally locked. Log in or sign up first. Not to mention that it's probably tidally locked to it's parent star after 8 billion years of being that close. In planetary science, tidal locking was a phenomenon whereby the rotational period of a planetary body about its axis equals its orbital period.This meant that one hemisphere of the planet always faced its parent or primary.. An example of a tidally-locked planet was Dytallix B, in orbit around Mira Antliae.This uninhabited planet was mined by the Dytallix Mining Company. Please consider turning off Ad-Block. Teegarden's Star B is distinct in that it appears to be relatively calm. But a tidally locked planet with an atmosphere something like Earth’s might redistribute heat fairly efficiently, says Koll. Both branches share the characteristic support/protective organ "siliceous laminate", layers of cartilaginous membranes impregnated with silicon in various formations and concentrations. Many are also visible to the naked eye. Upsilon Andromedae System - Titawin (Upsilon Andromeadae) is a nearby (44 ly) multi-star system which is the first multiplanet system found around a main sequence star or a multi-star system. Questions asked by the same visitor. That makes its year a bit shy of 3 TSB days, which is sure to frustrate some calendar-makers, and make some French philosophers very happy. Part of the speculative evolution appeal to me is the wonder that all these wild creatures are technically possible, somewhere and somewhen. Significant differences in temperatures, seasonality, chemistry, gravity, nychthemeron length, and so on and so on would lend themselves to greater biological divergence. We investigate the habitability of the exoplanets Teegarden’s Star b and c (hereafter TGb and TGc, repectively), and their potential to have an atmosphere that would support surface liquid water, using an atmospheric habitability model for locked planets (W18). In addition, both Teegarden b and c will, in all likelihood, be tidally locked with their star. Most, if not all, of the 7 Earth-sized planets in the ultra cool dwarf star system may only face one way towards their sun, similar to Earth’s moon. Notable clades of Thermidoria in this era include: Nimates: Primitive even among the primitive kingdom, nimates are pure thermosynthetes, resembling long plastic strands hanging in the water. The first is their namesake: a cluster of lenses that float above their main body, shielding it from the worst radiation, allowing them to grow above their competitors and closer to the light. So one side is in perpetual bright day, the other in perpetual night. In fact, this is the case for most the large moons in the solar system. The evolution of the isolated and potentially habitable Kepler planet candidates is computed and about half could be tidally locked. Have you ever read Gould's book Wonderful Life? WHY MONSTERHEARTS AND 3.X DND ARE EXACTLY THE SAME, AN ESSAY WITH AN INCENDIARY TITLE: Caverns of Thracia session log: February 2, 2019, The Plane of Lightning & Thoughts - Fulmens - Spells of the Storm-Wracked Noosphere, Weirdcrawl: Investigating the Weird and Wondrous, Storing Information, Playing Information, Dungeons. To add some spice to our primordial soup I'll suppose that some billions of years past Teegarden's Star was feistier, giving off the solar flares and bursts of ultraviolet radiation of most red dwarfs. Tidal locking (also called gravitational locking, captured rotation and spin–orbit locking), in the best-known case, occurs when an orbiting astronomical body always has the same face toward the object it is orbiting. The second is a "reel" which anchors them in the seabed. Tidally Locked Hot Jupiters In the News Edit Sample (Year) Edit Confirmed Example Systems Edit. Rather than both sexes producing gametes, only one diaphanian sex does. Griessmeier et al. Here's some links to some of my favourite speculative evolution projects: The Future is Wild: https://www.youtube.com/watch?v=Rbi8Jgx1CNE, Snaiad: http://www.cmkosemen.com/snaiad_web/snduterus.html, Biblaridion's Alien Biospheres series: https://www.youtube.com/watch?v=egzZv8tqT_k&list=PL6xPxnYMQpquNuaEffJzjGjMsr6VktCYl, The Epona newsletter: http://worldbuilders.info/epona/, The world of Serina: https://sites.google.com/site/worldofserina/home, The Planet Furaha blog: http://planetfuraha.blogspot.com, The Ilion blog: https://sunriseonilion.wordpress.com/ilion/. Proxima b is almost assuredly tidally locked, but its orbit may not have circularized yet, so the planet could be rotating super-synchronously today. Under certain conditions, mostly related to high population density, nouvatoids will overgrow their fuzz and roll around to disperse like underwater tumbleweeds. Kolliofacia: Worm-like burrowing creatures with a U-shaped digestive tract passing around their hemocoel, mouth and cloaca ending up much too close for most Earthlings' liking. When you need a dungeon but it can't be too interesting, Intro Statistics for RPGs: Cyberpunk's Weird Dice Math, A Note on Deceptive NPCs and More Crystal Frontier. Despite being at a severe disadvantage with energy production you can find them pretty much everywhere. In this submarine shelter the living kingdoms which will share the world to follow have formed: (If you know any Latin or Greek please correct my naming in the comments, I'm just using google translate). The fruiting body was porous to allow spores within it to catch a current, but the current also brought in microorganisms which were sometimes consumed. This surface liquid water that is thought to be present on both planets, makes for a … The clade was the first to develop genuine eyes, though given the long night sight tends to be underdeveloped as a sense compared to Earth. Since the habitable zone for red dwarfs (and for many orange dwarfs) falls inside this limit, many worlds located around these stars which might otherwise become temperate Gaian worlds are in fact tidally locked Vesperian worlds. These mycelia in turn grow spawning bodies that produce more of the mass. The basal ancestor of Tomatrichia is a creature somewhere between fungus, slime mold, and biofilm: a zoogleal mass of microorganisms that cooperate to construct mycelia-like structures with keratinous cell walls, sometimes dismantling each other and merging for the raw materials. The moon is older than Earth by approximately 300 million years. Close binary stars are found to be tidal locked, before being formed into 1 star. Tidally Locked Hot Jupiters Web Pages Edit. What is meant by the term "super-Earth"? The stars are too cool have habitable zones. https://www.youtube.com/watch?v=Rbi8Jgx1CNE, http://www.cmkosemen.com/snaiad_web/snduterus.html, https://www.youtube.com/watch?v=egzZv8tqT_k&list=PL6xPxnYMQpquNuaEffJzjGjMsr6VktCYl, https://sites.google.com/site/worldofserina/home, https://sunriseonilion.wordpress.com/ilion/. What would a species look like that isn't plant, animal, fungus, etc.? Tidal locking (or captured rotation) is when one side of an astronomical body always faces another.It is also called synchronous rotation.The classic example is the Moon: the same side of the Moon always faces the Earth.. A tidally locked body takes just as long to rotate around its own axis as it does to revolve around its partner. So, the Moon is tidally locked to the Earth because it rotates in exactly the same time as it takes to orbit the Earth. Living fossils even here at the harsh dawn. The Moon is tidally locked to the Earth, which means that it always shows one face to our planet. Nouvatoids: A group resembling fuzzy sea urchins. When the organism detects a dangerous increase in temperature or radiation, the reel pulls it down deeper beneath the water's protection. The kingdom Diaphania contains two branches, one of plant-like phototrophs and one of animal-like heterotrophs that lost their chloroplast-analogues. To understand what this means, we need only look up. In addition, both Teegarden b and c will, in all likelihood, be tidally locked with their star. That being said I think we have strong reason to believe that fast-moving aquatic predators, whether they're swimming through water or ammonia, will be torpedo-shaped, though even within that we've got everything from sharks to squid. Secondly, red dwarf stars tend to output a lot of solar flares. Perhaps in defiance of God and astrophysics, I'm going to say that my TSB is not tidally locked. This is all very cool, I'm also a fan of speculative biology / speculative evolution but this is much better researched and realized than what my biology and chemistry knowledge would allow lol.
