ma'am you are delightfully strange and I'm privileged to share a planet with you
You've heard of Earth is space australia now get ready for: Earth is the space Amazon Rainforest. Aliens land on Earth and they are losing their goddamn minds because every square inch of the ground is absolutely PACKED with life like there are hundreds of species just in this one site, there are winged animals flying through the sky and multiple colonies of sophisticated social insects just in the shadow of their ship, this ONE ROCK is covered in MULTIPLE SPECIES OF ORGANISMS that are themselves MULTIPLE ORGANISMS LIVING SYMBIOTICALLY, the tall, woody autotrophs look so different from each other because they're...holy shit that's like 5, 6, 7???? different species on this one site???
they start talking to a human and the human is like "haha yeah that's a crow!" and the alien researcher is like "you called it a 'bird' earlier, is that a different name?" and the human is like "oh a crow is just one species of bird, there's like, 10 others out there"
imagine aliens that come from a tidally locked planet where only a thin band of the planet is habitable, or a planet life was only able to develop in small areas at the poles, or in the few pools of liquid water on the planet's surface, or just in isolated areas where geologic activity causes geysers and springs, visiting Earth. They seem completely unprepared for the shock of realizing that Earth's continents appear green because the continents are absolutely covered with green organisms.
The alien biologists are so uncomfortable because there are certain protocols for maintaining certain distances from life signatures to avoid harming unfamiliar organisms, and groves of plant like autotrophs and pools where aquatic life dwells are carefully protected and respected, with very important rules for approach
On Earth, the inhabitants are just. Playing and walking LITERALLY STEPPING ON CARPETS OF ORGANISMS the whole time. the aliens are like "it doesn't hurt them??? Can't you just...move them to a place where you don't have to step on them?" and the humans are like "no of course not, grasses evolved to tolerate being stepped on, and besides, more plants would grow there if we tried to move the existing ones"
It then must be explained that humans would need to regularly spray poisons on the ground to prevent any given area of bare soil from filling up with plant life, and that "regularly" means "multiple times within a single solar cycle." And that the poisons stop working within a few decades because the plants evolve to resist them that fast.
Human: yeah solar is the dominant energy source these days but some of the recent solar farm projects are pretty controversial because they're in reclaimed strip mining sites that others argue should be restored as best as we can to their previous ecological state
Alien: I don't understand...why would you not place the solar farms in an area of the planet with no existing ecosystem?
Human: ...what?
Alien: You have rather sophisticated protective gear and have done some space exploration, surely you could establish them in an area of the planet to which life is not yet adapted?
"Our biologists would love to collaborate with your Earth scientists to draw up a definitive listing of Earth species and resolve any inconsistencies in the records."
"I don't think you understand what I'm saying. Only 25% of Earth's species have been formally described, at most."
"that's...that's most of them."
"Yes?"
"Well...I suppose the ocean trenches and abyssal plains must be difficult for you to reach...where did you have to travel for your discoveries?"
"Travel? I moved here to Alabama in the first place to study its aquatic ecosystems. The crayfish I discovered live in that creek I showed you earlier."
In Copenhagen you can visit The Round Tower. It used to be an astronomical observatory until light pollution and the vibrations from increased traffic in the streets made it useless for its original purpose.
Today it’s mostly famous for what it looks like on the inside.
It has an equestrian staircase though it’s so smooth it’s really just a gentle slope more than a staircase. It was build like that so our lazy bum king could ride his horse all the way to the top (king not in photo)
And naturally people have also driven cars up the tower
And held a bike race
For a while it was just sort of abandoned by the authorities and became a spiraling marketplace
But today it has been restored and become a tourist spot as well as a popular destination for school trips. And yes, you can still watch the cosmos at the top.
I have this idea for a video game called Are You Out There? where two players control two different alien civilizations and the goal of the game is to invent spaceflight and then manage to find one another in a ginormous universe. You can try to leave signs for each other to find, or send out probes and radio waves, or colonize many systems so you're a bigger target, but its hard because the universe is really big.
So my beta reader for the Big Fics is an astrophysicist, right. Who is currently also writing a hard sci-fi novel about the exploration of Phobos (more power to them, I cannot with the physics required for that, best I can do is soft sci-fi/fantasy and that reminds me I should finish that story).
Anyway I was bitching about how hard it is to come up with feasible planets in Star Wars because sometimes you need a new planet from scratch and sometimes you need to know more about a planet than the 'has jungles, is probably a moon technically' than Wookieepedia will give you, and they're like 'oh yeah I can do something about that'.
So they've written (in Matlab but they swear it will run as a .exe as well and I may be conscripted to embed it as a web tool at some point) a star system generator.
You input what you know about the planet (ecosystem, population, sun colour, does it have liquid water, does it have a moon or moons, is it a moon or moons, temperature averages, atmosphere, you get me) and it will give you the... everything else about the star system, in obedience to real-universe physics. And if you input nothing you get a randomly generated star system.
And I’m like oh I know people who will be into this with a vengeance, and they're not on Tumblr, so this is me seeing who exactly would be keen on, and I cannot stress this enough, a real-physics comprehensive star system generator.
It's still in the debugging phase (last error fixed: every planet wants to have a population of exactly 5000 regardless of other factors, turned out to be a missing equals sign somewhere), but I'm psyched for this and trying to gauge interest for how high a priority 'make this an accessible web tool' needs to be.
Overcome by my suspicion that even seemingly mundane things in the natural world still have important properties that we don't even know about, either because we don't know how to detect them yet or we haven't observed then yet under the right conditions or because they somehow don't lend themselves to the reductionist framework in which science operates.
INFORMATION I WAS NOT PREPARED TO LEARN. MAYBE WE *ARE* ALONE. BECAUSE WE ARE SO *EARLY*. IF THERE IS EVER GALACTIC CIVILIZATION THEY WILL NOT REMEMBER US AT ALL. BECAUSE WE ARE NOTHING. CELLS, JUST BEGINNING TO FORM LIFE. SORRY FOR SCREAMING. BUT ARE YOU LISTENING. ARE YOU THINKING ABOUT IT.
Well, there were some quirks. It was carbon-based, which was mildly interesting, and Arc’s shuttle readouts told her that it was the plants that had developed photosynthesis, weirdly. The atmosphere had a massive amount of oxygen, and there was all that water, too, more than she had ever seen in one place before. And every planet was, as her trainers had told her, its own unique jewel.
But one thing they had not told her was that all the jewels started to blend together after a while, and after a little longer each one became just another assignment. So the planet was just another assignment. A little ball of water and tumbled stone and flora in a cul-de-sac of the galaxy. One more stack of paperwork for Arc to get through before she could go home to her marital partners and offspring.
Arc aimed her shuttle in the middle of one of the larger continents, away from the mountain range and near a smaller body of (oh, gosh, more) water. As she got closer to the ground, though, her shuttle readouts changed. There were irregular smudges of radiation on the surface, and chemical evidence of constructed materials. Arc squinted, and her tertiary limbs started to shiver in frustration. There were ruins down there. Nobody had told her she’d be surveying a formerly inhabited planet. Great, she thought. Now I’m never getting home.
Arc sent a note by ansible to Ecba, her dearest marital partner. A few mins later, as her shuttle settled on the ground, she got back the image of a hand-sculpted message. “My little machine,” it said, Ecba’s sweetheart-name for her, and she could see all the love that went into the lettering. “Does it have to be you?”
Arc put on her enviro-suit and got her surveying monitor. “Maybe not,” she sent. She didn’t have the same skill in sculpting that Ecba had, so she just had to trust that her love was conveyed in the digital lettering. “Wish me luck. I’ll try to come home to you all soon.”
Then she stepped out into the world.
The first thing she noticed was that the sky was blue. It was disconcerting, to say the least. Blue was for water, and some crystal formations, and nebulae, not the sky. She wondered what it had done to whatever inhabitants used to live here, to have such a bright, unwieldy color as the backdrop of their days. If they used the light spectrum to see at all, that was. Well, she thought as she carried her surveying monitor away from the shuttle, she’d find out.
The second thing she noticed was that the ruins were invisible from the ground. All she could see for kiloms and kiloms was wildly ambitious vegetation, some rocks, and the melodramatic blue of the sky. The ruins must have been old enough that any wood or rock or even petroleum deposits would have broken down into microscopic pieces, from time or the weather, or been buried. Whatever she was dealing with wasn’t just gone, it was long gone.
Arc felt herself start to get interested, despite her desire to go home. Junior surveyors like her didn’t get mysteries like this. Ruins were one thing, the residue of a solitary existence before the inhabitants discovered, or were discovered by, other planets and polities, and they left to make a new life among the stars. But mysteries were something else.
She found a flat place to set up her surveying monitor, and set the aperture. Immediately she was surrounded by a hologram re-creation of her surroundings. She figured five thousand years was long enough, to start with. She flipped the dial back, clacked her secondary limbs for luck, and told it to go.
Nothing. The hologram was the same, just ruins and vegetation.
Arc checked the monitor. It seemed to be working fine. She turned it off and turned it on again just to make sure. Then she set it for ten thousand years.
Ruins. Vegetation. Nothing else.
Arc turned the hologram off, and sat back and looked around. The vegetation gave her no answers. She clacked her limbs in confusion, and then thought, Fuck it, and set the monitor for a hundred thousand years. Even if she missed the departure point, the thing she was always told to capture first, at least she’d get something.
Nothing. Even so far back, everything was exactly the same.
Arc started to get a bad feeling. She tried two hundred thousand years, and nothing. Three hundred thousand years. Then, feeling like she was losing her mind, she set it back five hundred thousand years.
And, there.
It wasn’t the inhabitants, but she could see traces of the buildings they had built for themselves, in the process of crumbling to nothing. She started creeping slowly back in time from there: year after year. The weather patterns on the monitor were very different from what she was experiencing now, with scorching heat and hurricanes, the air filled with ash. There was no vegetation. Arc’s bad feeling crystallized into fear.
Finally, finally, she found a living soul. Just one, wandering through the ruins, shielding itself from the blistering sunlight. It walked right in front of her on the hologram, and turned and looked straight through her. She stared at it, trying to understand.
It was a soft, squishy thing, bipedal and barely coming to half her height. It moved like nothing she'd ever seen, and she shouldn't have been able to read any emotion in that strange face and those alien limbs. But she saw grief there, she was sure of it.
Back, and back. The ruins rebuilt themselves, the weather patterns steadied. Arc saw more of those strange bipedal beings, and other squishy creatures that connected to the beings with string. She saw small fauna and stone roads, machines that moved and buildings so tall they blocked out the sky. She found a group of three, a taller being and two very short ones, and watched them for a long time, as they came and went from the image of the building in front of her. After watching them for a while, she realized that they were a family.
Arc found another being, and watched it making something out of wood: a little carving of one of the creatures that moved along on string. She saw beings creating machines that made images, and she saw beings painting colors on walls. She saw beings fighting each other, killing each other, mourning each other. She saw them raising each other, playing with each other. She saw them making and making: creating by themselves, creating together. And all of them so long ago, long before even Arc's people, the oldest civilization she knew, had begun to walk among the stars.
These beings, the ones that had lived hundreds of thousands of years ago, had spent the entire course of their existence alone in the universe. The ruins weren't ruins because they had left for better things. The ruins were ruins because they had died out, all of them, millennia before they could be found.
Arc felt grief well up inside of her, and she began to keen. This wasn't the way it was supposed to be. Life was meant to find other life; that's what life was for.
How lonely they must have been, she thought, singing her mourning song for them. All that creation, all that art and all that play, the machines that made images, the paint scrawled on walls, the carvings made with strange limbs but with so much love that Arc could feel it even now — and they couldn't share it with anyone. How impossible the galaxy, the universe, must have felt to them.
I’m sorry, she thought, and keened for them. I’m sorry you were all alone. I’m sorry we were too late for you, and that you were too early for us. I'm sorry for all of it. But we’re here now. We have you. You’re not alone anymore, and you’ll never be alone again.
After a while she calmed. The holographic images were still going, and she found herself struck by another family: this one had many large beings and a few small ones, and it was clear in their movements how much they loved each other. That was important, she thought. That love was what was left, after everything. That love was what she was here to preserve.
Arc got up off the ground on shaky limbs, still grief-stricken but feeling stronger. She went back to her shuttle and sent the images she had recorded to her supervisors, along with a note that they needed to send more of her colleagues, now, so that everything could be captured faithfully.
She also sent a note to Ecba. “My star,” Arc wrote. “I have memories I need to excavate here. I am sorry I will not be home soon. I will come back when I can, but in the meantime know that I love you, and our family.”
Then she got her carving tools, and her clay. She wasn't as good as Ecba, but this memory, these stories, deserved the work of her hands.
Arc went back to her surveying monitor. She turned it on, and wound it back and back, farther than she’d ever imagined it was possible for life to go. She braced herself for grief again, and for the love she was going to find. She arranged her clay, and picked up her tools. She let the monitor play, showing her the planet’s long, brilliant memory. And then she began to tell the story.
the way the dinosaurs were here for like 180 million years and we're just like ughhh rip to the monsters. now onto the main story of planet earth humanity. btw we're 3 seconds old
Comparing the rotations of objects in the Solar System. Just look at them lol.✨🪐
To everyone that's confused, the planet Venus rotates very very slowly, with a single revolution taking about 243 Earth days, and Mercury rotates slowly, but not as slow as Venus.
i was like "i wish mercury and venus were still animated tho" and then when i opened it to reblog the image was in starting position with mercury's eyes off to the side and i realized they ARE animated. super slow.
Today Jupiter Icy Moons Explorer is a third of the way to the Jovian system. He is currently using his high gain antenna as a sun shield. Telemetry is promising and he is full of vigor.
Today Pioneer 9 is silent. They carry on in a heliocentric orbit at 0.8 AU, and are likely still in the same, stable, spinning orientation they have been in for 58 years.
Today Pioneer 10 is dead. She is some 21 billion kilometers out, under a tenth of the way to the Oort cloud. She is no longer aligned with Earth, and the Sun looks to her like any other star in the sky.
details for the Ten piece since i like it the most :3 vvv
Astronauts are so funny man. Here's just a couple of things I've found hilarious from this past week of space stuff:
It's probably already been spread around here enough already, but in case anyone's missed it; 7 hours after launch, commander Reid Wiseman, dealing with tech issues, uttered the generational quote "I have two Microsoft Outlooks and neither one of those are working."
After fixing the issues that were afflicting the onboard toilet, mission specialist Christina Koch (who has quickly become my favourite of the four) laughingly said “I’m the space plumber, I’m proud to call myself the space plumber.”
On Easter Sunday, the Artemis II crew hosted a makeshift egg hunt, by hiding packets of dehydrated scrambled eggs around their Orion capsule.
The way the crew always makes sure to make it very clear they're in space when doing interviews. From stuff like Wiseman just hanging out floating sideways on screen or Koch letting her hair loose so it can freely span out flowing around her.
While in transit, the crew decided to record a parody of those bad 80s sitcom intros where everyone turns and smiles at the camera.
When the crew reached the furthest point from Earth in the mission, they jokingly clambored over each other in an effort to get to the far side of the capsule, so that they could individually claim to be the furthest person from earth.
At the same time, on the ISS which was at the time on the other side of earth, the 7 astronauts onboard had a light-hearted race to the far side of the station, making jokes about being the furthest humans from Artemis.
On the way back to earth, NASA actually managed to establish an audio call between the crews of the ISS and Artemis II (where they shared the above info), and Koch called one member of the ISS crew, Jessica Meir, her "astro-sister" as the two of them previously spacewalker together in 2019. Meir then responded I'm so happy that we are back in space together, even if we are a few miles apart" (a few here being 230,000).
While Jeremy Hansen was doing an interview, Wiseman and Koch were just in the background swatting the mission mascot (a little moon plush toy named Rise) back and forth between each other.
