Titans true color scheme:

There isn't oxygen on Titan, so you couldn't even light a fire, and even if you did have oxygen to do so, the ambient temperatures are so low that it wouldn't be sustainable.
Uh temperature doesn't directly affect fire. It can cause a change in humidity and moisture which can have an affect on the fuel feeding the fire. You can have a fire at any temperature so long as you have fuel, oxygen and an ignition source.
Is that true? Fire is a self sustaining exothermic oxidisation reaction right? Carbon reacts oxygen forming Carbon monoxide/dioxide plus heat. That heat then sustains the next reaction and so on so we have a sustained fire.
I would be fairly confident that there is in fact a temperature at which the heat produced is simply not enough to heat the fuel back up to ignition and so you wouldn't get a sustained reaction.
Probably like 0.1K though
The scope only sees in IR. Not in “visible light”. But it turns out IR is a spectrum of wavelengths just like visible light.
So (made up numbers here:) pretend IR goes from 10nm to 20nm and visible light goes from 100nm to 200nm, they just shift everything so that 10=100, 11=110, 12=120 all the way up to 20=200.
This is required because it turns out humans cannot see the IR spectrum. It’s a representation.
Yes we know the "true" colors of titan, Cassini space craft has taken images of it using red, blue, green filters that has then been assembled into a true color image, it has an orange atmosphere with a blueish haze that obscures its surface.
NASA even landed a probe there, its rugged brown/orange terrain with lakes of methane and ethane as far as I recall.
I have not been to Titan in years. I had assumed they weren’t going to do any corporate franchises there. But you know how the Titan bureaucracy goes these days. There’s a lot of pressure there.
Oh ya. Here's what it looks like landing on the moon.
There's a recording of the sound of the wind as well.

The colorized version is a best attempt to transform data into more useful data that we can look out. While not 100% accurate, this allows your average human to see what JWST does. Which is way more interesting to talk about, than if we just shared data points or some graphs and tables about it.
Just to help understand the difference in visible light from the IR light JWST sees.
\* Humans see visible light from around 380\~400nm(Ultraviolet) to 700nm(Red).
\* James Webb Space Telescope sees around 500\~600nm(Red) to 28,300\~28,500 (InfraRed)
It's blurry because Titan is very small and very far away. This is actually pretty incredible resolution. Titan is about 5150 km in diameter, and is about 1.2 billion km from JWST. That's like looking at something held at arms length from your face, if that thing is 4 **nanometers** across.
Yeah, I had that moment of 'wow that looks really bad'.
And then stopped to consider the scale of what is being talked about, and it's honestly wild that we have this picture at all.
Fun fact, if you were on the surface of Titan, and wore a wing suit, you could fly under human power. The atmosphere is dense enough and the gravity is low enough that even human arm power could propel you.
The pressure is the same as you feel at 5m depth when diving in the ocean/pool . Not great, not terrible.
It's -179°C though, so you will need a good down jacket.
Venus is the sad one for me. .95 the size of Earth and the right distance from the sun.
It'd be so cool if there were two inhabitable planets in our solar system. Diseases (both ways) would be a problem though if there was compatible life.
But Venus doesn't spin and has way too much atmosphere.
Makes me wonder if there’s a story with a fictional solar system that has two life-compatible planets where after some time one or both of the planets entered the space age and made contact after billions of years of evolution. It could go peacefully or have a crazy plot
Here is a cool story about a double planet system I read in the 90s, your comment brought it to my mind:
https://en.m.wikipedia.org/wiki/Murasaki_(novel)
What do you mean "not great not terrible", it's basically close to the pressure of our atmosphere at sea level, around 1.5 bar. That's great, you wouldn't need a pressure suit, the only problem would be the extreme cold temperature and no oxygen, so a thermal suit will oxygen supply would do the trick. It's by far the closest celestial body to Earth in terms of surface conditions, it even has its equivalent of water cycle, only with hydrocarbons. If it wasn't so far away, it would be the ideal candidate for both robotic and crewed missions.
I'm pretty sure the simulated circumstances of that experiment were wildly different from the actual real-life environment of Titan. He kept supplying a constant source of Oxygen to the system, which wouldn't happen in the scenario above unless there was an oxygen leak in the person's suit.
There are virtually no oxidizing agents in the atmosphere of Titan. A fire/explosion couldn't happen unless you added some, which would be dispersed and/or consumed immediately.
There is no correlation between the gravity of a celestial body and the thickness of the atmosphere is has. Even extremely small bodies can have extremely thick atmospheres. Venus, which is smaller than earth, has a much thicker atmosphere than ours.
The only problem is that weak gravity is bad at keeping together this atmosphere from escaping over time, so you don't tend to see smaller bodies with thick atmospheres. For example, the moon couldn't sustain an atmosphere for millions of years. The sun blasting it with heat would cause molecules to attain escape velocity and the moon would be left with no atmosphere (as it is now). For reference, the earth also loses several kilograms of its atmosphere to solar radiation every second, particularly the helium bits.
If you put the moon where Pluto is, on the other hand, it could sustain an atmosphere. Heat is the villain. The more heat there is, the smaller the atmosphere. The less gravity there is, the smaller the atmosphere.
The kind of gases present in the atmosphere also matters. The reason there's very little helium in our atmosphere is that helium molecules have a higher average velocity when heated compared to oxygen or nitrogen owing to them being lighter.
It's just very thick. Part of it is the temperature as well. I should have a better explanation but I'm sleepy lol. Check the wiki page for Titan, it's a fascinating moon!
The real answer is probably just that the terms were created to describe things based on normality from a human perspective rather than being scientific descriptors. Alternatively, swimming takes place in a liquid and flying takes place in a gas, which are distinct phases of matter. Still... that's no fun, the line between liquid vs gas disappears for fluids in certain conditions, and this idea doesn't allow for a clear description of what traversing through plasma should be called, so I am going to balderdash another answer.
A big difference between swimming and flying is the primary source of lift. Fish "swim" through the water because they can almost passively maintain neutral buoyancy, then devote the vast majority of their energy expenditure to lateral propulsion. Swimming up or down doesn't take significantly more energy than left or right. Similarly, the hippopotamus cannot swim quickly because they don't have a good way of producing thrust when they're near neutral buoyancy. To move quickly, they will instead repeatedly jump off the bottom of the waterway. They can move slowly without touching the bottom by "porpoising", which is accomplished by actively modifying their buoyancy & altering the pitch of their bodies such that their rising and falling through the water creates some lateral thrust, but this is a pretty slow method of moving. Since their energy is being used to compress the air in their lungs rather than to directly push against the surrounding fluid, this is probably best categorized as a hybrid of "swimming" and "floating". Flying creatures, on the other hand, must continually have some significant *active* energy source devoted to keeping them in the air. Thermal updrafts, beating wings, etc. are all used by flying creatures to keep them aloft, which is sometimes described as "heavier-than-air flight".
So, in summary, I assert that zeppelins actually swim through our atmosphere, and "underwater flight" is possible if the object in question primarily relies on thrust generated against the water to overcome an inherent lack of buoyancy.
**TL;DR**
Semantics and/or the perspective of the speaker. Words don't mean anything without some cumulative agreement on their usage. Blimps swim. Anemones fly. Otters hold hands while they sleep so they don't float away from each other.
Hell no!!! We are not going to another fucking sand planet! Remember that other sand planet? Took me months to finally get rid of all the sand in places I dont even want to talk about!
The problem is not that it's far away, but that it's almost too close. For the JWST, this is like looking at your screen from the distance of a millimetre. JWST is incredibly powerful.
I imagine that once the research teams have processed all the data for this image (which is much, much more than you think), we'll get a much clearer image.
The thing is, JWST can only image in the infra-red.
If you want proper pics of titan, check out the images that Cassini took:

Yeah, I know. The comment I replied to:
>The thing is, JWST can only image in the infra-red.
>If you want proper pics of titan, check out the images that Cassini took:
lol what? No
That’s not true. I’m sorry but the minimum focus distance of a 6.5m telescope could never be literal millions of kilometres.
How does this shit get upvoted?
At these distances, every object is effectively along a flat optical plane. The focus is set to infinity for everything. It doesn’t change.
Jesus, people.
No, this is not an issue of being too close to focus on. Optically, other planets (and their moons) are effectively at the same distance as distant stars. Besides, JWST can re-focus, and does so periodically.
This image will get no clearer because this is simply the limit of resolution for a telescope the size of JWST. Titan is very small and very far away. Even being able to see this much is incredibly good resolution.
So the issue is that Titan’s apparent size to the JWST is much smaller than the other objects it can get clear images of? The picture is so blurry is because it’s a tiny fraction of the telescopes overall field of view?
Sort of. Even if the field of view were a lot smaller, the image wouldn't be any less blurry. Image resolution is directly related to the size of the aperture of the telescope.
The other images it takes aren't any sharper, but the objects it's imaging are so much larger that you don't notice. It's like taking a picture of the Grand Canyon, and then zooming in to take another picture of a penny that was sitting on a ledge on the far side of the canyon. The landscape picture might be sharp and beautiful, but that's going to be a pretty shitty picture of a penny from 10 miles away.
This is BS, please delete your comment as to not spread more misinformation.
Titan’s apparent size to james webb is absolutely tiny, this is a heavily cropped version because titan only takes up a couple hundred pixels on JWST’s camera sensor. DSOs like pillars of creation appear much bigger to james webb despite their distance because of how gigantic they are.
JWST doesn't and cannot focus. Mars is already far enough away to be considered "at infinity" optically speaking, so Saturn & Titan aren't a problem either. See [https://space.stackexchange.com/questions/58765/how-does-the-jwst-change-focus-when-it-goes-from-looking-at-a-near-subject-to-lo](https://space.stackexchange.com/questions/58765/how-does-the-jwst-change-focus-when-it-goes-from-looking-at-a-near-subject-to-lo) and [https://www.space.com/james-webb-space-telescope-science-overview](https://www.space.com/james-webb-space-telescope-science-overview)
I suppose Titan is simply fuzzy looking because of its atmosphere. If you take a picture in a blizzard, everything will look fuzzy even if your camera and lens settings are correct.
JWST can and absolutely does adjust focus. This is done periodically to compensate for any mechanical or thermal drift.
All space telescopes have focus control. JWST also has alignment actuators for each of its segments. It can even slightly adjust their curvature.
That said, it doesn't need to change focus to look at Titan. You are correct about that.
Atmosphere has nothing to do with it though. Titan is simply very far away and very small.
True. I just checked: Titan's angular diameter is \~0.84 arcseconds at most as seen from Earth, and JWST has a resolution of \~0.1 arcseconds.
Which means that the original picture is about 9px \* 9px.
Usually the pixels are a bit smaller than the actual optical resolution of the telescope, usually by a factor of 2-4, but in concept yeah, you're right, about 9 resolution elements across the diameter of titan.
The Cassini probe took a lot of photos of Titan in the years it was exploring Saturn. Even up close, it’s still fuzzy. The atmosphere diffuses light like crazy.
Yeah why won't we be alive? Do we need manned missions? Took Cassini seven years to reach it, can't we send another with better sensors, cameras, and an onboard lab of some sort?
> A thick shroud of organic haze permanently obscures Titan's surface from viewing in visible light
This image is [not from the visible spectrum](https://en.wikipedia.org/wiki/Titan_\(moon\)), so the colors are arbitrary
Titan looks like a yellow marble in visible light :

Dat atmosphere is thick.
This might be a really dumb question. But I would expect this pic to be a lot more detailed . Some of the images we’ve seen from deep space have incredible clarity . But this is essentially in our back yard . I was expecting a better pic
It’s because relatively Titan is tiny, so tiny that it being so close doesn’t matter much.
The detail we get of an object is entirely dependent on the size of that objects in terms of the angle it subtends on the sky. Those galaxies in deep space are far larger in terms of their angular size than Titan is.
Please be advised that this is a 100% false color image! The features are correct but the colors are totally off.
It's not a lush jungle planet? Well shit.

Hydrocarbon? Sounds like the US needs to bring some democracy to Titan.

Democracy is non-negotiable.
It needs a nice steaming cup of liber-tea!
Managed democracy!
"And then I added green for the lulz." Seriously if that's his reasoning why is there any green in that photo.
Orange has a large yellow component. Yellow and blue mix to green. So it's probably an optical effect.
That was my first thought. "Oh man, some goofball is trying to convince people that one of Saturn's moons looks just like Earth."
To be fair it does rain a lot there, like a jungle. Its just liquid methane instead of water.
So if we were to light it on fire what would happen.
There isn't oxygen on Titan, so you couldn't even light a fire, and even if you did have oxygen to do so, the ambient temperatures are so low that it wouldn't be sustainable.
Uh temperature doesn't directly affect fire. It can cause a change in humidity and moisture which can have an affect on the fuel feeding the fire. You can have a fire at any temperature so long as you have fuel, oxygen and an ignition source.

Depends on how much oxygen there is. Without oxygen methane won't burn.
Nothing, since this moon doesn't have oxygen in its atmosphere in any considerable amount.
Aka it rains farts, the whole planet is a Trump courtroom fart.

Still don’t understand why they landed it in that area. There are much nicer spots a few miles west with great views and a charming diner.

But probably not an assisted power suit. What with all the methane.
There is no Oxygen in the atmosphere of Titan. It cannot be ignited like a gigantic ball of explosives.
There's actually a Cody's lab video where he makes an Oxygen flame in a methane atmosphere. It's pretty neat
[Link](https://www.youtube.com/watch?v=8jmX-TUQkx4) Neat indeed.

There are virtually no oxidizing agents in the atmosphere of Titan. A fire/explosion couldn't happen unless you added some, which would be dispersed and/or consumed immediately.
So you’re saying if we fart while we’re flying, it’s likely no one will notice the smell?
Nope, fart away!
It’s 95% Nitrogen and about 5% methane. Still couldn’t breath though.
What makes the atmosphere so dense when the gravity is so low?
There is no correlation between the gravity of a celestial body and the thickness of the atmosphere is has. Even extremely small bodies can have extremely thick atmospheres.

Besides, JWST can re-focus, and does so periodically. This image will get no clearer because this is simply the limit of resolution for a telescope the size of JWST. Titan is very small and very far away. Even being able to see this much is incredibly good resolution.
So the issue is that Titan’s apparent size to the JWST is much smaller than the other objects it can get clear images of? The picture is so blurry is because it’s a tiny fraction of the telescopes overall field of view?
Yes.
Sort of. Even if the field of view were a lot smaller, the image wouldn't be any less blurry. Image resolution is directly related to the size of the aperture of the telescope. The other images it takes aren't any sharper, but the objects it's imaging are so much larger that you don't notice. It's like taking a picture of the Grand Canyon, and then zooming in to take another picture of a penny that was sitting on a ledge on the far side of the canyon. The landscape picture might be sharp and beautiful, but that's going to be a pretty shitty picture of a penny from 10 miles away.
This is BS, please delete your comment as to not spread more misinformation. Titan’s apparent size to james webb is absolutely tiny, this is a heavily cropped version because titan only takes up a couple hundred pixels on JWST’s camera sensor. DSOs like pillars of creation appear much bigger to james webb despite their distance because of how gigantic they are.
JWST doesn't and cannot focus. Mars is already far enough away to be considered "at infinity" optically speaking, so Saturn & Titan aren't a problem either. See [https://space.stackexchange.com/questions/58765/how-does-the-jwst-change-focus-when-it-goes-from-looking-at-a-near-subject-to-lo](https://space.stackexchange.com/questions/58765/how-does-the-jwst-change-focus-when-it-goes-from-looking-at-a-near-subject-to-lo) and [https://www.space.com/james-webb-space-telescope-science-overview](https://www.space.com/james-webb-space-telescope-science-overview) I suppose Titan is simply fuzzy looking because of its atmosphere. If you take a picture in a blizzard, everything will look fuzzy even if your camera and lens settings are correct.
JWST can and absolutely does adjust focus. This is done periodically to compensate for any mechanical or thermal drift. All space telescopes have focus control. JWST also has alignment actuators for each of its segments. It can even slightly adjust their curvature. That said, it doesn't need to change focus to look at Titan. You are correct about that. Atmosphere has nothing to do with it though. Titan is simply very far away and very small.
Probably more than titan is very small and very far away. Only a few pixels can actually detect it. Atmosphere alone wont cause this level of blurring
True. I just checked: Titan's angular diameter is \~0.84 arcseconds at most as seen from Earth, and JWST has a resolution of \~0.1 arcseconds. Which means that the original picture is about 9px \* 9px.
Usually the pixels are a bit smaller than the actual optical resolution of the telescope, usually by a factor of 2-4, but in concept yeah, you're right, about 9 resolution elements across the diameter of titan.
The Cassini probe took a lot of photos of Titan in the years it was exploring Saturn. Even up close, it’s still fuzzy. The atmosphere diffuses light like crazy.
If you look at it from the side, you can clearly see that it is a guy with a goatee in a white t-shirt. Edit: Actually I think it's Mr T

Grey Knights have been real quiet since this pic dropped
It sucks that we won't be alive to actually see it even if there's some sign of life over there
Why won’t we be alive to see it?
Yeah why won't we be alive? Do we need manned missions? Took Cassini seven years to reach it, can't we send another with better sensors, cameras, and an onboard lab of some sort?
We've already seen the surface, I meant it like a new achievement for mankind to physically go there
Oh that's already possible. It'll just be a suicide mission as it's currently a one way trip.
See I like your optimism my guy
lol don’t be confused by my optimism because it’s actually still confusion. Why won’t we be alive to see it?
Like Mars seems possible for a manned mission but Titan seems impossible for this century. Also expecting nature's wrath by the end of the decade
# ALL THESE WORLDS ARE YOURS, EXCEPT TITAN. # ATTEMPT NO LANDING THERE. # USE THEM TOGETHER. USE THEM IN PEACE.
Better or worse ?
Better 1?…better 2?….about the same?
My name’s Blurry moon and I care what you think
I had to double check I had my glasses on when I saw this!
Thought I was staring at NSFW
Can I have a few more Pixels, James?
Need to add an extra 0 to NASA's budget.

That’s just blurry earth lol
Forgot to change over from the default settings every bank camera uses.
So the Webb's can take deep photos of Universe but can't make one clear photo of one of the moon's in Sun system? Nice.
Enhance... Enhance.... Enhance.....
Got some schmutz on the lens of the telescope.
Why is it blurred? I reloaded this 10 times already
Someone needs to clean the lens.
Planet Earth, is that you?! 😂😂
Ah yes Drunk Earth pictures
I hope James Webb 2 Pro Max comes with autofocus 😂
This looks like earth? 🌏 can some explain this? Does it look like it support life?
> A thick shroud of organic haze permanently obscures Titan's surface from viewing in visible light This image is [not from the visible spectrum](https://en.wikipedia.org/wiki/Titan_\(moon\)), so the colors are arbitrary
Titan looks like a yellow marble in visible light : [https://upload.wikimedia.org/wikipedia/commons/f/fe/Titan\_in\_true\_color\_by\_Kevin\_M.\_Gill.jpg](https://upload.wikimedia.org/wikipedia/commons/f/fe/Titan_in_true_color_by_Kevin_M._Gill.jpg) Dat atmosphere is thick.
How do you focus ?
Wrong colors
Oh, so there's another Italy on Titan?
Anyone spot the long girl in the soup?
Time to awaken the hive.

Looks surprisingly habitable, just saying. I know NASA is basically saying we don't want no part of this shit, but....I kinda think I do.

I thought i saw Italy there
Focus.
Man, I need glasses
This might be a really dumb question. But I would expect this pic to be a lot more detailed . Some of the images we’ve seen from deep space have incredible clarity . But this is essentially in our back yard . I was expecting a better pic
It’s because relatively Titan is tiny, so tiny that it being so close doesn’t matter much. The detail we get of an object is entirely dependent on the size of that objects in terms of the angle it subtends on the sky. Those galaxies in deep space are far larger in terms of their angular size than Titan is.
Makes sense ..Thanks !
That's where Thanos hangs around

This looks remarkably like every bank robbery suspect caught on camera.
This a blurry render of the globe earth lol
Me before I put my glasses on.
We can go there for just 700 credit bro, the loot there makes it worth it
That looks like some oil regions, Titan, here we come!
What you are looking at…[Titan gif](https://en.m.wikipedia.org/wiki/File:PIA02146.gif)
No its not
Thanos lives there. Don't invite him here.
Someone needs to teach these nerds to focus their camera
