I've seen things you people wouldn't believe... Attack ships on fire off the shoulder of Orion... I watched C-beams glitter in the dark near the Tannhäuser Gate. All those moments will be lost in time, like tears in rain... Time to die.
I don't know why he saved my life. Maybe in those last moments he loved life more than he ever had before. Not just his life - anybody's life; my life. All he'd wanted were the same answers the rest of us want. Where do I come from? Where am I going? How long have I got? All I could do was sit there and watch him die.
It is beautiful and was rewritten the night before shooting by the Rutger Hauer himself. He cut it down and added the tears in the rain line, which is the line that is the most poetic and human. Harrison Ford looks perplexed because he had no idea what the other actor was going to say. It just perfectly plays into the scene, with Deckard being confused by the replicants' last words and mercy. The film crew applauded after its unexpected and astounding delivery.
It doesn't actually look like the Earth. The colors are purely an artist's depiction.
The image is originally infrared but has to be converted so that we can see it, hence why it's not realistic.
Its not because of clickbait, its just that they chose 3 wavelengths of light that would let them see past the cloud layers, and assigned red to the longest one, green to the middle, and blue to the shortest one.
> [Color composite image](https://webbtelescope.org/contents/early-highlights/webb-keck-telescopes-team-up-to-track-clouds-on-saturns-moon-titan) using a combination of NIRCam filters: Blue=F140M (1.40 microns), Green=F150W (1.50 microns), Red=F200W (1.99 microns), Brightness=F210M (2.09 microns)
Edit: if you want to see why they would pick these, [look at this](https://www.eso.org/public/images/eso0408b/) Going longer wavelengths would mean its blocked by the atmosphere, and shorter ones dont reveal as much detail.
Tbh, im surprised nobody has made a new post showing the better pictures of Titan from Cassini showing the [sun reflecting off its lakes of methane](https://upload.wikimedia.org/wikipedia/commons/a/a0/Specular_Spectacular_%28PIA18432%29.jpg), and [a more general pic of its lakes](https://d2pn8kiwq2w21t.cloudfront.net/original_images/jpegPIA20016.jpg) (yes both are infrared false color, since otherwise it looks [like this](https://upload.wikimedia.org/wikipedia/commons/f/fe/Titan_in_true_color_by_Kevin_M._Gill.jpg))
Titan most likely would actually show up as blue-green to human eyes if you were in orbit staring down at the world. It has a thick methane atmosphere with a "methane cycle" just like we have a water cycle here. There are methane clouds, rain, rivers, and lakes on Titan.
Interestingly, due to the thick atmosphere (1.5x as dense as Earth's) and very low gravity (less than 1/7th of Earth's), the methane rain falls super slowly. I'd imagine it looks surreal and beautiful. I hope I get to see video footage of rainfall on Titan in my lifetime!
I think there is a major miscommunication of science when people who do astrophotography fail to mention the part of artificially replacing colors, when they show their photos to the general public. It should be an etiquette thing for astrophotographers to add that disclaimer. Most people have no idea.
You're wrong here, because 1) they do communicate it constantly, more over, the Webb team put it on every picture, [see example](https://stsci-opo.org/STScI-01HQP7771P4QR3Q3DNT1Q90ZTV.png) (in the bottom part of the image - it's the filters/wavelengths and the colors assigned to them) 2) you understand it wrong. They don't "replace colors", they assign them in the same chromatic order our eyes have, especially in this case when they have to translate the infrared spectrum invisible to us into our visible spectrum. They don't just randomly paint in whatever colors they want.
> the bottom part of the image - it's the filters/wavelengths and the colors assigned to them
This means absolutely nothing to the group of people he's referring to, non astrophotographists. It doesn't matter the mechanism of what they're doing, what they're communicating to the general public is this is what it looks like.
But what does it mean? I don't know shit about it so "translate the infrared spectrum invisibile to us into our visible spectrum" doesn't really explain anything about why they do it to someone who has no idea what you are talking about.
The telescope measures infrared. We can't see infrared, and our computers monitors can't display it, only RGB. So what they do is take a section of wavelength that the telescope recorded and assign it a colour that we can see, and which monitors can produce. The colour assignments are pretty arbitrary, this image is 3-channel which means they split up all the recorded wavelength into 3 separate sections (from high wavelength to medium to low) and display each section as red, green, and blue. They could just as well do 5-channel and split the recorded wavelengths into purple, blue, red, green, and yellow, or any other combination.
Imagine you can only hear certain frequencies, but you want to listen to a piece of music that is outside of those frequencies. You would transpose the music to the frequencies that you can hear so that you can listen to it.
That is what these images do. They add a certain number to the frequency so that we can interpret the image as light instead of heat.
its like readjusting the whole range. So imagine you have a song that is too low pitched for you to hear it, so the whole song is altered to be a few octaves higher. Now you can hear the music. Its not the same pitch, but the relationship between the elements is preserved.
It's not 'purely artistic'. There are *some* artistic decisions such as contrast/balance but colors are assigned based on the same wavelength-chromatic order our eyes have. It shows colors you would see if you had eyes perceiving the infrared spectrum in a similar way to how you see the visible spectrum.
Heyyyy my eye sight is so much worse in one eye as well. If i only have one contact in my bad eye, i can see like 80% as well as i could with both contacts in. While if i only have the one in my better eye it only makes a slight difference. If i cant read something in small print no matter how close it is to my face, i have to close my right eye in order to read it. And if i get too close my vision just unfocuses and i cant read shit. This is such a stupid disease. I literally had 20/20 perfect vision just 7 years ago. I went from perfect vision to being unable to pass the drivers vision test (so techincally makes me legally blind without my contacts i think) within 3 years its so fking stupid how fast my vision deteriorated in 3 fucking years. Thankfully ive had sclerals for almost 3 years now and my vision is almost perfect besides some very small starbursts around LED lights at night.
Is not your fault, thank you tho. I wasnt fishing for that, but i preciates you none the less. Now to be honest with you, im the guy that blinded you, so i am truly sorry about that.
Keratoconus mentioned !!!
This shit sucks and with being an 'invisible disability' it so much fun trying to explain to people why you can't do certain things. Like driving at night or working more than 12 hours.
Sometimes it's 5 inches, and sometimes it's 3 inches. Honestly, it depends on whether or not its cold out, how wet it got effect it as well. The colder it is the shorter it is. And by the multple its, i mean my eyes and the distance i need to read stuff on my phone.
It's not that it's too close, it's that it's too small. James Webb has an angular resolution of about 0.1 arcseconds, and Titan is roughly 0.8 arcseconds in apparent size. So Webb isn't going to be able to resolve features that are smaller than about 1/8 the width of Titan. If it was closer, you'd actually get a much clearer picture from Webb.
When you see crystal clear images of things like nebula from these telescopes, they look super clear and detailed not because they're far away, but because those nebula are actually REALLY big. The Orion nebula, for example, has an apparent size of 65 arcMINUTES. That's about 5000 times greater apparent size in the sky compared to Titan.
False. That’s the resolution limit. Despite its large mirror, JWST is still diffraction limited and can only resolve angles larger than 1.22 * wavelength / mirror diameter. That boils down to approx 0.1 arc seconds for JWST, and titan is only ~5100km in diameter but at least 1.2 billion kilometers from earth.
Exactly. Luckily we had the [Cassini](https://science.nasa.gov/missions/cassini/titan-flyby-t-100-the-closest-remaining-brush-with-titan/) probe take a bunch of close loops there so we have higher-res images.
The distance at which focus movement no longer distinguishes the range of the subject is determined by aperture. This is why a 50mm f1.4 lens might have its last distance marker at 20 meters with barely any movement to infinity, while a 24mm f2.8 lens might only have 3m as the last notch, and a 300 f2.8 might have 50 meters and then a big gap to infinity.
My 250mm aperture telescope requires refocusing between objects a few kilometers away and other objects a slightly different distance down range.
JWST has a 6.5 meter mirror. That's 182 times bigger than a 50mm 1.4 lens aperture. At 20 meters being the last notch on such a lens, the logical conclusion is that for jwst this "near infinity" marker would be 3.6 kilometers away.
I did a Google and to find the point where infinity focus is functionally the same as a non-infinite focus position, you look for the hyperfocal distance. I plugged what I knew of JWST into a calculator and it suggested a hyperfocal distance of 11'400 kilometers. Which means JWST could happily take pictures of the moon (but not really since it can't point at the moon without exposing itself to the sun).
https://www.omnicalculator.com/other/hyperfocal-distance
Ok, so why is it blurry, then?
Edit: Someone else explained it. Titan is 5100km across but 1.2 BILLION kilometers away. So this is the resolution limit. It's just that we're usually seeing JWST images of things that are very much larger, even if they are also very much further away.
Jupiter is roughly as large in the night sky as ~~the pillars of creation~~ one of the pillars in the Pillars of Creation, and the James Webb has taken some sharp pictures of Jupiter, the moons of Jupiter are just pin holes in comparison.
(To the human eye, Jupiter looks like the ~~brightest and~~ largest "star" in the sky).
Titan is one of the seven gravitationally rounded moons of Saturn and the second-most distant among them. Frequently described as a planet-like moon, Titan is 50% larger (in diameter) than Earth's Moon and 80% more massive.
It is the second-largest moon in the Solar System after Jupiter's moon Ganymede, and is larger than Mercury, but only 40% as massive due to Mercury being made of mostly dense iron and rock, while a large portion of Titan is made of less-dense ice.
Titan is the only moon in the solar system with an atmosphere, and it has a gravity that is similar to Earth’s. It even has lakes and rivers—except on Titan, the “waterways” are actually liquid methane and ethane (liquid because the surface is very cold, minus-291 degrees Fahrenheit).
Gravity similar to earth?
While everything else is pretty much correct that part is just wrong. Unless you add moon to that.
Surface gravity of titan is a bit less than that of our moon. Nowhere close to actual earth.
I imagine a NASA scientist reading that to a room full of reporters with this image on the screen. Then, she accidentally hits a control panel and fully focuses the image, revealing an extremely earthlike planet.
Poor NASA scientist. She got home and killed herself with two bullet holes in the back of their head. I'm sure those Men in Black made a strong case as to why those reporters need to get rid of their news story.
Orbiting Titan is more hospitable than Titan itself but many people do think it could be home to non-Earth-like life right now or a human colony in the future.
Likewise when the sun goes Red Giant its thought the habitability zone may extend out to Jupiter and Saturns moons while the Earth gets fried.
> when the sun goes Red Giant
by that time if we don't crack superluminal flight, then we don't deserve to exist as a species. doesn't matter if Titan is habitable or not. change my mind.
I think that’s sort of what he’s saying. That it’s so far into the future that if we are unable to figure that shit out with all the resources and infrastructure and knowledge we have, given how quickly the industry has been progressing… we must’ve fucked ourselves up and therefore we don’t deserve it
Faster than light travel is likely physically impossible, to an equal extent as travelling back in time. If so, it's certainly not a prerequisite for "deserving" to exist. But it may not be necessary in the first place - a species could be entirely capable of spreading across the galaxy using slower than light travel.
Beyond some scientists and engineers, it probably wouldn't do most people any good. However, given its vast abundance of hydrocarbons, I could forsee it being a great candidate for some kind of drone-controlled industrial hub. But even then, it's so far away that even if the tech needed becomes more than capable, the costs would likely outweigh the benefits for quite some time.
There’s a video somewhere on YouTube that describes what it would be like going to Saturn.
I forget the details, but to paraphrase from memory: once you get into Saturns gravity, there is no escape. It takes days to get closer and closer into the atmosphere. At some point, the winds will shred you. At a later point, the density of the atmosphere will crush you and all your systems. Something like that
Here it is: https://youtu.be/TGaW-c7T4f8?si=sdPybHOnarg6TKLf
> That’s why astronomers look for free oxygen in exoplanets atmospheres—it’s a good sign there’s life happening.
Sounds like ‘carbon-based life’ bias all over again.
This reminds me of how scientists from the manhattan project at some point feared that the detonation of a nuclear bomb could ignite the entirety of earths atmosphere
It's not as dumb as it sounds, but luckily it turned out not to be the case.
It wouldn't have been on fire, burning... it would have been a runaway nuclear reaction with the rather plentiful Nitrogen in the air.
Someone did the math, and determined that it was highly unlikely.
Fortunately, they were correct.
The whole thing is kind of interesting.
Well, it's a bit like the LHC potentially knocking us out of a false vacuum state into a lower energy level and destroying the entire universe in the process. A bummer, but unlikely enough not to lose too much sleep about it.
In quantum physics, something can often be "possible" but the chance of it happening is so ridiculously low it may as well be disregarded. It's also possible that random fluctuations spontaneously create a thinking human brain out of thin air, but we all know how likely that is...
Stuff like that last part becomes interesting regarding deep time. If you wait long enough, far beyond when the last star has died, the chance of weird shit like that happening at *some* point starts becoming likely.
> Oxygen makes other things ignite at a lower temperature, and burn hotter and faster.
You make it sound like the oxygen is just a catalyst that helps things along. The fuel and oxygen bonding together *is* fire.
The fire generally continues until the fuel is depleted because oxygen is abundant on Earth. What the other comment pointed out is that the oxygen abundance is reversed on Titan and a fire would burn until the oxygen is depleted
Crap, I just realized you said free oxygen reacting with diatomic oxygen to make ozone. I explained it using diatomic oxygen to ozone. I don't wanna spend the time going over the radical reaction you mentioned. But, in short, it would be three zero oxidation (0) atoms resulting in two that are reduced and one that is oxidized.
O₂ + O ---> O₃
O=O + O --->
[^(-)O--O^(+)==O <---> O==O^(+)--O^(-)]
I think Titan is blurry, that's the problem. It's not the JWST’s fault. Titan is blurry, and that's extra scary to me. There's a large, out-of-focus moon roaming the solar system. Run, he's fuzzy, get out of here.
Titan is the only object we know of that has large lakes of liquid on its surface.
The lakes are made of hydrocarbons though, and the rock of the landmasses are various ices

Here is a much more clear, but composite picture of Titan for those curious.
To the people saying this is fake, a quick google search easily clears up the confusion. There has been a discussion about this image on Reddit back in 2022 as well [here.](https://www.reddit.com/r/space/comments/zio3f3/james_webb_space_telescope_acquired_this_view_of/) And I easily found an article with a lot of information regarding this image [here](https://www.livescience.com/clouds-found-on-saturn-moon-titan-jwst).
I am amazed still that people see something weird on Reddit and just spew out their opinion, when it would have taken them a minute to google the image and find out whether something is fake or not. It literally took me no more than two minutes to find out whether this was fake or not.
I totally would have gotten a better focus if I used my old Canon . I don’t know who this Mr Webb dude maybe a fantasy writer or somethin , stick to the writing shtick .

yep, thats why it makes sense to assign RGB to those wavelengths in that order.

Does James Webb have cataracts or something?
Problem is Titan is too close for JWST. Imagine browsing Reddit with your screen 2cm from your eyes.

I had to move my phone away from my face after reading that

The Orion nebula, for example, has an apparent size of 65 arcMINUTES. That's about 5000 times greater apparent size in the sky compared to Titan.
I read somewhere that Nebulas wouldn’t be so visible if we were in it.
False. That’s the resolution limit. Despite its large mirror, JWST is still diffraction limited and can only resolve angles larger than 1.22 * wavelength / mirror diameter. That boils down to approx 0.1 arc seconds for JWST, and titan is only ~5100km in diameter but at least 1.2 billion kilometers from earth.
Drives home how massive the things that it can resolve must be.
At a distance of 1.5 million km from earth, the 0.1 arcsecond resolution of JWST corresponds to roughly 0.7 km per pixel. In other words... maybe.
So Titan is too small to resolve any further with jwst?
Exactly. Luckily we had the [Cassini](https://science.nasa.gov/missions/cassini/titan-flyby-t-100-the-closest-remaining-brush-with-titan/) probe take a bunch of close loops there so we have higher-res images.

The distance at which focus movement no longer distinguishes the range of the subject is determined by aperture. This is why a 50mm f1.4 lens might have its last distance marker at 20 meters with barely any movement to infinity, while a 24mm f2.8 lens might only have 3m as the last notch, and a 300 f2.8 might have 50 meters and then a big gap to infinity. My 250mm aperture telescope requires refocusing between objects a few kilometers away and other objects a slightly different distance down range. JWST has a 6.5 meter mirror. That's 182 times bigger than a 50mm 1.4 lens aperture. At 20 meters being the last notch on such a lens, the logical conclusion is that for jwst this "near infinity" marker would be 3.6 kilometers away. I did a Google and to find the point where infinity focus is functionally the same as a non-infinite focus position, you look for the hyperfocal distance. I plugged what I knew of JWST into a calculator and it suggested a hyperfocal distance of 11'400 kilometers. Which means JWST could happily take pictures of the moon (but not really since it can't point at the moon without exposing itself to the sun). https://www.omnicalculator.com/other/hyperfocal-distance
Ok, so why is it blurry, then? Edit: Someone else explained it. Titan is 5100km across but 1.2 BILLION kilometers away. So this is the resolution limit. It's just that we're usually seeing JWST images of things that are very much larger, even if they are also very much further away.
Jupiter is roughly as large in the night sky as ~~the pillars of creation~~ one of the pillars in the Pillars of Creation, and the James Webb has taken some sharp pictures of Jupiter, the moons of Jupiter are just pin holes in comparison. (To the human eye, Jupiter looks like the ~~brightest and~~ largest "star" in the sky).
It's like trying to look at a grain of sand at arm's length instead of a mountain range in the distance.
Looks like a blurry “Earth”.

Titan is one of the seven gravitationally rounded moons of Saturn and the second-most distant among them. Frequently described as a planet-like moon, Titan is 50% larger (in diameter) than Earth's Moon and 80% more massive. It is the second-largest moon in the Solar System after Jupiter's moon Ganymede, and is larger than Mercury, but only 40% as massive due to Mercury being made of mostly dense iron and rock, while a large portion of Titan is made of less-dense ice. Titan is the only moon in the solar system with an atmosphere, and it has a gravity that is similar to Earth’s. It even has lakes and rivers—except on Titan, the “waterways” are actually liquid methane and ethane (liquid because the surface is very cold, minus-291 degrees Fahrenheit).
Gravity similar to earth? While everything else is pretty much correct that part is just wrong. Unless you add moon to that. Surface gravity of titan is a bit less than that of our moon. Nowhere close to actual earth.
And the atmosphere is so dense, that with hand-held wings, you could fly. [Relevant XKCD.](https://xkcd.com/620/)
>!He really gave us this fun factoid just to setup an Icarus joke. Amazing!<
It’s so weird to think, that if the conditions were slightly different, we may have wings. Just blows my mind.
Terminal velocity for a human on Titan is like 14mph. The atmosphere is nitrogen. It may actually be more habitable than Mars.

Came here to post this too 😂 well done
That's hilarious 😂
Professor Brian Cox and Ross Noble double act - who knew, right?
Oh my god, this is so hilarious. I'm basically dehydrated from laughing and crying 😭
I imagine a NASA scientist reading that to a room full of reporters with this image on the screen. Then, she accidentally hits a control panel and fully focuses the image, revealing an extremely earthlike planet.
Poor NASA scientist. She got home and killed herself with two bullet holes in the back of their head. I'm sure those Men in Black made a strong case as to why those reporters need to get rid of their news story.
Small correction: The gravitational acceleration on Titan's surface is 1/7 of Earth's. That's less than on our moon.
Earth 2.0, lets send the billionaires there to scout it out for us, I'm sure they'll single handily build a giga factory in a week.
In the future, would this be the next logical step after Mars to send people?
Orbiting Titan is more hospitable than Titan itself but many people do think it could be home to non-Earth-like life right now or a human colony in the future. Likewise when the sun goes Red Giant its thought the habitability zone may extend out to Jupiter and Saturns moons while the Earth gets fried.
> when the sun goes Red Giant by that time if we don't crack superluminal flight, then we don't deserve to exist as a species. doesn't matter if Titan is habitable or not. change my mind.
Here's hoping. Being stupid as fuck would be the worst way to be remembered by other species
Thats 5 billion years in the future my guy, chill out. There is plenty of time
I think that’s sort of what he’s saying. That it’s so far into the future that if we are unable to figure that shit out with all the resources and infrastructure and knowledge we have, given how quickly the industry has been progressing… we must’ve fucked ourselves up and therefore we don’t deserve it
That's his point.
The procrastinator's motto! But what happens in 4.999 billion years when we still haven't gotten our homework done?
Faster than light travel is likely physically impossible, to an equal extent as travelling back in time. If so, it's certainly not a prerequisite for "deserving" to exist. But it may not be necessary in the first place - a species could be entirely capable of spreading across the galaxy using slower than light travel.
When I was 8 years old I wrote a short story about everyone moving to Jupiter because the sun expanded. I'm glad to see that I was right!
No, titan was swallowed up by the witness's pyramid fleet

Beyond some scientists and engineers, it probably wouldn't do most people any good. However, given its vast abundance of hydrocarbons, I could forsee it being a great candidate for some kind of drone-controlled industrial hub. But even then, it's so far away that even if the tech needed becomes more than capable, the costs would likely outweigh the benefits for quite some time.
[удалено]
When you say go to Saturn, it's not like you can land there
[удалено]
Oh no, you'd legit just be crushed and vapourised
This thread is amazing.
There’s a video somewhere on YouTube that describes what it would be like going to Saturn. I forget the details, but to paraphrase from memory: once you get into Saturns gravity, there is no escape. It takes days to get closer and closer into the atmosphere. At some point, the winds will shred you. At a later point, the density of the atmosphere will crush you and all your systems. Something like that Here it is: https://youtu.be/TGaW-c7T4f8?si=sdPybHOnarg6TKLf
crazy to think its full of methane but no oxygen. So its like the opposite of earth, methane isnt flammable there, oxygen is.
[удалено]
> That’s why astronomers look for free oxygen in exoplanets atmospheres—it’s a good sign there’s life happening. Sounds like ‘carbon-based life’ bias all over again.
Oxygen is definitely still flammable here...
Oxygen makes other things ignite at a lower temperature, and burn hotter and faster. But oxygen itself does not catch fire.
This reminds me of how scientists from the manhattan project at some point feared that the detonation of a nuclear bomb could ignite the entirety of earths atmosphere
It's not as dumb as it sounds, but luckily it turned out not to be the case. It wouldn't have been on fire, burning... it would have been a runaway nuclear reaction with the rather plentiful Nitrogen in the air. Someone did the math, and determined that it was highly unlikely. Fortunately, they were correct. The whole thing is kind of interesting.
but it is still kinda crazy that they ended up being like, 'you know what, fuck it, let's try it!'
Well, it's a bit like the LHC potentially knocking us out of a false vacuum state into a lower energy level and destroying the entire universe in the process. A bummer, but unlikely enough not to lose too much sleep about it.
In quantum physics, something can often be "possible" but the chance of it happening is so ridiculously low it may as well be disregarded. It's also possible that random fluctuations spontaneously create a thinking human brain out of thin air, but we all know how likely that is... Stuff like that last part becomes interesting regarding deep time. If you wait long enough, far beyond when the last star has died, the chance of weird shit like that happening at *some* point starts becoming likely.

> Oxygen makes other things ignite at a lower temperature, and burn hotter and faster. You make it sound like the oxygen is just a catalyst that helps things along. The fuel and oxygen bonding together *is* fire. The fire generally continues until the fuel is depleted because oxygen is abundant on Earth. What the other comment pointed out is that the oxygen abundance is reversed on Titan and a fire would burn until the oxygen is depleted
if you heat diatomic oxygen enough, itll make ozone, which is *kinda* burning oxygen (since youre combining free oxygen to diatomic oxygen)
Crap, I just realized you said free oxygen reacting with diatomic oxygen to make ozone. I explained it using diatomic oxygen to ozone. I don't wanna spend the time going over the radical reaction you mentioned. But, in short, it would be three zero oxidation (0) atoms resulting in two that are reduced and one that is oxidized. O₂ + O ---> O₃ O=O + O ---> [^(-)O--O^(+)==O <---> O==O^(+)--O^(-)]
Huh? I tried lighting my lighter and nothing blew up.
That is very interesting to think about!
Someone needs to get up there and clean the lens. /s
Its Hive infested anyway.
Bring a sword.
I thought it was vaulted out of existence.
There are much better pictures of Titan: https://www.wired.com/story/space-photos-week-terrific-tantalizing-titan/
Cassini. What a mission. What a story.

I think Titan is blurry, that's the problem. It's not the JWST’s fault. Titan is blurry, and that's extra scary to me. There's a large, out-of-focus moon roaming the solar system. Run, he's fuzzy, get out of here.
Cameraman sucks bruh
r/killthecameraman
They should let it go. I don't think it's ethical to keep these things in captivity.
Is it me or does it seems to have landmass and oceans?
Titan is the only object we know of that has large lakes of liquid on its surface. The lakes are made of hydrocarbons though, and the rock of the landmasses are various ices
Lakes of fuel?
🤑🤑 do I hear it has OIL?!
Instead of a water cycle, Titan has a methane cycle. It literally rains methane there.

This is where Thanos is from right?
Correct.
Haha thanks
Are you sure it is not a potato because that could just be a potato
Pretty good image considering it's 746 million miles, or 1.2 billion kilometers away.
The colour has been altered to look like earth. This photo is not an accurate representation of Titan and has been colour edited
I don't want to be a party pooper but your telescope is out of focus
This thread is going to be filled with people that dont understand the scale of space isnt it... And they will all be updated for their halfass jokes and assumptions and a whole new group of people will leave here being mislead. This is the worst part of reddit.
https://media.npr.org/assets/img/2017/10/16/titan-41d62a75c7b7376fe8ff872bb1deec3bc24a4a14-s1600-c85.webp Here is a much more clear, but composite picture of Titan for those curious.
Damn picture won't load
To the people saying this is fake, a quick google search easily clears up the confusion. There has been a discussion about this image on Reddit back in 2022 as well [here.](https://www.reddit.com/r/space/comments/zio3f3/james_webb_space_telescope_acquired_this_view_of/) And I easily found an article with a lot of information regarding this image [here](https://www.livescience.com/clouds-found-on-saturn-moon-titan-jwst). I am amazed still that people see something weird on Reddit and just spew out their opinion, when it would have taken them a minute to google the image and find out whether something is fake or not. It literally took me no more than two minutes to find out whether this was fake or not.
This is me, looking at a picture of the Earth without my glasses on at -5.25 vision.
Looks very earthy
I can almost see the huge leviathan from here.
That MF has life
The telescope is perfectly focused, it's the moon that is blurry.
"rubs eyes"
I totally would have gotten a better focus if I used my old Canon . I don’t know who this Mr Webb dude maybe a fantasy writer or somethin , stick to the writing shtick .

Fun fact: Titan, [much like bigfoot](https://www.youtube.com/watch?v=eMm1YTd8lHM), is actually blurry.
Is it NSFW?
Stop it. Thats totally a blurred picture of Earth.
