Are we landmass shaming now?
As someone who used mapmaking software for decades I agree they all look randomly generated.
How did they get it to pose next to earth for this photo?
Kepler-452b was having a private conversation with Australia when the photographer snuck up and got the candid photo.
Unfortunately Kepler-452b was embarrassed by having the intimate moment interrupted and left in a hurry.
Though their conversation was pleasant, the photographer ruined the mood and numbers were not exchanged.
Asking the real questions
Earth 2 exists, except it’s twice the size of Earth and could be a scorched wasteland for all we know.
Whenever I see an update on these sort of articles, the planet always ends up being a tide-locked hells-scape full of toxic chemicals.

Slightly unrelated but I got a solid chuckle out of the different modes they added in the drop down on the XKCD website under teh comic, Space Opera mode is my favorite.
So basically what billionaires are trying to turn the world into? /s
You may not like it, but that's what's what peak habitability looks like

for lizard people
Maybe, just maybe, billionaires have been there before?
It looks so shit cause they've already nuked themselves to planetary death. And because of climate change and rising sea level. Also ecosystem degradation and subsequent soil erosion. I've heard you need to prevent these to keep Earth beautiful. Just for the aesthetics. Think about the astronauts, what if they had to look at an ugly Earth?
No but seriously, why DO continents/landmasses on other planets give a sense of unease/uncanny valley (at least to me)? Is it just the lack of familiarity?
I get the same feeling when looking at fractals.
On one hand I want to explore everything but at the same time I know it's impossible to grasp.
Our own Earth has fixing points from man made stuff, so I sort of know what's where, but then I zoom in on the archipelagos in south Chile or the lakes in Lapland and I get confused again because it seems soo randomly generated.
Beyond what's been said already, we 100% do not have any way to take a picture of a planet outside our solar system that shows any detail of the planet's surface, and no plans to make a telescope that can do that. What we do right now to even tell if there are planets around other starts is look at the star's light and see if it gets slightly darker on regular intervals, indicating that a planet is crossing between us and the star in a regular orbit. Right now we can barely take a decent picture of Pluto, which is in our solar system. And checking the light brightness is really only good for looking for large planets the size of Jupiter and Saturn.
It's like seeing a car at night on a mountainside 4 miles away with its headlights on. It's just sitting there and you are wondering if it's a car or something else. It's hard to even tell it's 2 lights, it just looks like one light from that distance. But what would we see if someone walked in front of the car with the headlights on? The light get dim on one side and bright again, then dim and bright again on the other side. Sort of the same thing.
As for the uncanny valley part, it's because whoever came up with the graphic just did a random splash of water and land. The planet could be orange and magenta-colored, we have no idea. They used colors familiar to us looking at images of Earth because the intent is to make you think "it's like Earth, but different."
It's an artist's impression. We almost certainly got no idea what its continents look like at that distance.
Why not, all you have to do is take a blurry photo of it and just keep saying enhance, right?
We almost certainly got no idea what its continents look like at that distance.
I understand this, but I also get unease from RNG maps from games like Age of Empires or Anno, and I've talked to a couple of other people who also have experienced this, so I was wondering if there was an underlying psychology to it. However, it's not an easily Googleable query, and I refuse to ask an AI chatbot about it.
I think a lot of it is humans are used to maps formed by tectonic plates shifting, glaciers forming and melting, storms and other weather, etc... When it's just an RNG heightmap it's missing all those familiar features like rivers, mountains, and dry lakebeds
Abnormalities from "normal" were a critical self defence feature, for our ancestors. E.g. a lack, or change, of bird song might indicate a predator in ambush. Unusual lighting might indicate a storm coming in.
Our brains are wired to learn normal patterns. When those patterns change completely, we are fine with it. When they change subtly we don't like it.
The threshold for this is different for different people. Personally, I'm fine with completely different maps, but off put by modified real maps. I also cannot watch soap operas, they are too close to "real" and trip alarms at their mismatches. Conversely, sci-fi and fantasy are fine, they are different enough to not set off my alarms. I know others who are set off by sci-fi, but soaps are within their norms.
You've only ever seen photographs of one planet with oceans and landmasses, and that's Earth. The only other celestial body that has a solid surface with liquid on it that we've taken pictures of is Saturn's moon Titan. Titan has a thick opaque atmosphere so we don't have true-to-life pictures of the surface from space. We've got images constructed from radar scans, and this amazing image taken from the surface by the Huygens probe that hitched a ride with Cassini. The hydrocarbon lakes of Titan look like...blobs on a circle.
Every other planetary surface you've seen is rocky dirt, icy dirt, straight-up ice, cratery dirt, or opaque gas clouds. Any "earth-like" planet you've ever seen is a fictional artist's conception. And ain't no human artist who knows shit about plate tectonics compared to the Earth herself, so they draw weird shit that ain't quite right somehow.

Wait this is so true, and I've never even thought about it. Space photography has a lot of pictures from the Moon, Mars, and Venus (I've never seen those Titan photos, so thank you for the link), but there are no "real" photos of a planet with oceans. That might be where the "uncanny valley" kicks in, with my brain going "this doesn't look quite right". I do get a similar feeling when I see AIgen videos, so you might be onto something!
Venus is difficult to photograph for the same reason as Titan, thick opaque atmosphere. We've got radar imagery of Venus, plus the Soviets landed some probes and took a few pictures of the actual hell that surface level Venus is.
We can actually get a pretty good look at Mars from here; This is a picture of Mars taken with Hubble. We have active missions in orbit and on the surface of Mars as well so we can look at it as close as we want.
Meanwhile, this is the best Hubble could do with Pluto. And that's still inside our own solar system, we're not getting any photos of the surface of Earth mass planets around other stars.
I think in part because speculating what the land looks like on an alien planet is actually really hard to do, and the vast majority of artists just wing it. With sufficient planning and rigor, alien planets should look normal.
For instance, I think the landmass of Tira-292b looks pretty natural. It's a hypothetical planet created for the Alien Biospheres project, a YouTube series that tries to build up an alien ecosystem as accurately to science as reasonably possible
It's a seriously underrated series, I highly recommend everyone check it out
I just googled Tira-292b and you know what, it doesn't set off that uneasy feeling for me. It just...kind of looks like Westeros? Which is based on parts of Earth so I guess that makes sense.
Alien Biospheres project
Also, thank you for the recommendation, I WILL be checking this out, if only to test my uncanny valley triggers to this a bit more. Time to experiment on myself 😭
Oh, the spider-squids definitely will trigger your disgust response. At least they evolve into something nicer after a while
There's no way in hell we have the resolution to see continents in another star system.
Soon, though, using gravitational lensing of the sun. Sometime around 2035 maybe.
You know that picture we have of the milky way?
Considering we only know it's there because it slightly dims the light from its star as it crosses during its orbit, you would be correct. At that distance, we would never see light bouncing off the actual planet. Even the star is basically a single pixel. We can estimate its size and orbit based on how quickly it crosses in front of the star and how much the light dims, and using those two numbers we can estimate its distance from Kepler 452.
I thought they could also see atmospheric composition as it passes in front of the star, no? Having that info and the data you’ve just mentioned they postulate if it’s habitable or not. Obviously not seeing any detail at all about land mass shapes, but perhaps composition? I’m not a spaceologist, so I’m only musing.
Yeah, but it's still just a single pixel of light from the star. It just changes color slightly when the planet passes in front of it and the atmosphere gases absorb certain characteristic wavelengths.
These are always illustrations based on whatever data we could gather. We almost never "see" the planets themselves.

"You can fit so much Perlin noise on this baby."
Here, go nuts:

Best freely available, scientifically based planet generator I've been able to find.
Weird. And cool.
Wow this app stinks. Did it spoil or something?
Supports linux yay :3
So thats where rimworld got the shitty planet generation from. Seriously, I want big contiguous oceans. Not like I can use the vast majority of the planet anyway.
How dare you shit talk Pangea like that
I think the point is that they aren't assuming the planet in question is tectonically activie, as that's one of the unlikely steps needed for life as we know it.
Since it's just perlin noise anyway... They should use gag landmasses for fun. See if anyone recognises Middle Earth or the Seven Kingdoms.
Isn't the 7 Kingdoms just England? With Scotland being north of the wall (which...LMAO at the implications on that one George)
They chose "randomize" in the New Game options
