+SBroproductions because there are aliens and water everywhere and stupid people don't believe it, because they don't think, what they do is to follow someone, and the discussion is between following one or another, when it shouldn't be about following but thinking.
+Rottensteam According to the internet, the Earth is flat! Also, the Moon is a spaceship! Also, the military is hiding a secret teleporter to Mars! Also there are alien cities on Mars!
Aren't they worried about contaminating Enceladus with extremophiles, hence they crashed Cassini into Saturn? I wonder what steps are needed to decontaminate spacecraft.
+ljmasternoob And we're finding out there is no such thing as a habitable zone, because planets (and moons) can generate heat from the inside, so life may live well outside what we use to call "the habitable zone". When we find life, we might find we've been surrounded.
i really wish you hadn't pointed this out,... i usually let these run in the background to listen to and don't look at the screen but now i'm just staring at her waiting for her to blink. wtf! ugh, there's a half blink at 2:26 on one of the scene cuts. the head bobbing distracts from the teleprompter reading but still!!!!
+SwedishPerson Intriguing question. The ocean on Enceladus might be very different to how we think of them on Earth. It could be a viscous, saline slush... more akin to magma on Earth than a traditional free flowing liquid. I don't know.
+Twixgtx you'd need to work out g with G and Encelidus's mass and radius. Which is tricky because deep inside you'd be guesstimating on the depth of ice, and core composition for an accurate model.
+Thomas Mason aren't alots a bit small, and also quite fuzzy, so even smaller than they look like? Unless you mean that there won't be much pressure compared to Earth's oceans, then I agree
Imagine showing this video to someone 60 years ago... "Oceans on another moon? Astronauts in space for a year?!" We've learned so much and we're just scratching the surface.
They should supply those astronauts with plenty of books. Im sure that would extend their morale and productivity for about a year and a half longer. Of course, they must have some personal favourites and what not.
The coolest thing about this year in space mission is that Kelly has and identical twin brother, also an astronaut, who is staying on the ground so when he returns they can make direct comparisons!
iambiggus I just read the book, knowing that it would be way better than the movie. It was, in fact, fantastic. I feel like more people will watch the movie however, and a video not long after its release would be pretty topical.
+iambiggus I read the book and listened to the audiobook. The latter has an extended ending with a funny interaction with a kid, not sure why it didn't feature in my paperback.
Any older folks remember it being hammered into our education that Earth is the only place that has water? Good to see science expanding what we know as fact. Keep exploring!
+Fortstorm I'm pretty sure it was all water. That, and we of course were taught that there are 9 planets, and Carbon Dioxide is good for the environment. At this point, I just kind of roll with it. I don't know how old you are, but once you hit the 30's, if you can remember the facts from your youth, facts change. Some for the best, like East/West Germany being a thing, and others just leave you thinking, "well, that can't be right."
It's not like a planet needs to produce heat or be heated in any way to have liquid water - the deep seas aren't called the "crushing depths" for no reason. The immense pressures from the weight of the ice can increase the pressure so much that water doesn't freeze for hundreds of degrees below zero. I haven't done any calculations for how much pressure would be needed for an ocean the size of Enceladus's, though. So it's entirely possible that there isn't enough pressure from the ice to bring it down to a liquid form.
Love Sci-Show! Watch the kids channel with my kids all the time and this one and the main with my friends. Will there be a Sci-Show episode about the Super-moon and Lunar eclipse that is supposed to happen on Sunday 27 September starting at 9:09 ET?
That is the first time I heard of a link between living in a confined space and a lack of motivation. So, if I were spending most of my time inside my home, and every day, doing similar things...that would cause a motivational decline. ...That would explain a lot of things.
I used to just stay inside and I got really low self esteem and motivation. my friend asked me to go running with him and I have every other day for about 3 months now and I feel 1,000,000 times better. not only is the increased motivation and self esteem better, but I am overall a lot healthier physically lol
Rob Rod And if you don't like running. Simply taking a different path each time you leave home can improve your health. Same goes with picking random places to visit along the way or going to random events. Variety of experiences is very healthy for your brain.
with the water so deep wouldn't just the weight of the water and ice above it be enough to keep the water in a state of liquid regardless of temperature? we have that effect here on earth, waters under glaciers that are below freezing but still liquid due to pressure.
Enceladus' tidal heating doesn't mesh with the results and the New Horizon results show that Pluto acts like it has tidal heating but it doesn't. ...I think we're on the verge of re-thinking a lot of things.
I wonder if it could still have a geologically active, or at least hot, core and inner surface. I'm sure its no Io, that has its teeny orbit and Jupiters titanic gravity, but if its a rocky core there could be plenty of radioactives to decay and heat it. We'll have to probe and see!
+сталкер чворович The concentration of those radioactive elements in materials protoplanetary nebula (and therefore in planetoids and planets) is way too low to be a sufficient explanation, especially for such a small body that, unlike Earth, is mostly made of water rather than rock and metal. Tidal heating remains by far the most likely explanation as to why so much of this water is liquid, with perhaps a minor contribution from radioactive decay. The error that caused the possibility of a global ocean to be overlooked in the first place probably lies within our understanding of the complex process of tidal heating, an overestimation of the thermal conductivity of that ice crust, or possibly the migration of its orbit further away from Saturn.
Okay, so Enceladus has water without tidal heating, and Pluto has active geology without tidal heating. What are we missing? Could this have implications for rogue planets or dwarf planets? Why isn't this process affecting Mars?
If the tidal heating from Saturn is strong enough to melt all that ice would it also be strong enough to produce the friction required for underwater lightning? Is underwater lightning even possible? Are these silly questions?
Enceladus is by far my favorite object in our solar system ! That ice is like a huge radiation shield for possible life to thrive !That would be incredible if microscopic life existed in the oceans of Enceladus , Titan , or Europa . I cant wait for the Europa Multiple Flyby Mission. If I had any power I would team up with NASA, ROSCOSMOS and the ESA to put together a massive mission to each of these wonderful moons!!
Forget microscopic life, what if there's giant Nordic space worms the size of a jumbo jet living there? That would be badass, I would want to ride one.
Just think of what the water molecule is made of - hydrogen, which is the most abundant in the universe, and oxygen, which pretty much every supernova farts out. And considering how little energy is needed to bond the two together, you really can say that there's much water in the universe. Well, much compared to us of course, on the cosmic scale, it just barely constitutes a drop.... pun intended.
Hasn't it been suggested that a gas giants gravity could put enough stress on an icy moon to produce enough heat to keep ice from forming? I recall reading something like that years ago, about one of Jupiter's moons. It could also not be water under the ice.
Maybe, if it's just water. There's probably other minerals dissolved in it. And knowing NASA, they would lock it away for months in ultra high security storage 'just in case' it contains alien superbugs or something...
Wait... if Enceladus has been spewing water for a few hundred million or billion years, then is it possible that Enceladus could have been much bigger than it is right now? Like it's dying a slow shrinking death.
It seems like water would have been a pretty decent amount of the protoplanetary disk, starting at the inner boundary of the "habitable zone" and going out. Any loose oxygen would probably have bonded with the preponderance of hydrogen and there you go. If the water molecules were distributed more or less evenly, then anywhere in the solar system it could exist, it would. Which seems to be what astronomers are finding now. I think eventually we're going to just drop the whole "comets brought the water" idea as unnecessary. That always seemed stupid to me anyway, cause wow, that would be a lot of comets.
+EJGilb In micro-g water will tend to form a thin film around anything it touches - tricky-sticky surface tension and all that wet. Now, if you had hydrophobic shoes, but then again - which way is 'up' to walk against? Oh drat, there goes my orange juice...
+EJGilb In any substantial gravity field (i.e. a moon) density gradients remain relative. That is to say sinking and floating depends on the density of the two objects in question. In short - no, you could not walk on water. You would, however, sink more slowly in a lower gravity field.
but if you could apply enough force on the water (since it still has mass relative to you) could you generate enough propulsion to stay sort of on the surface
They should send a playstation up and require the astronauts spend at least a couple of hours every day relaxing outside of their eating and sleeping time, or use their weekends to relax. Burnout is caused by an imbalance of work and relaxation... excessive work without enough down-time leads to burnout. They might be prestigious scientists, but they're still workers and we should all advocate for their rights.
As I appreciate the amazing work put into these experiments, and I acknowledge the immense quantity of extremely useful details and results that will come out of them, I think even 10 people repeating this experiment wouldn't be a high enough number to judge for this kind of psychological studies at a world-average level, even with thorough personality checks before the game; it very well could be a minor personality trait that some of them appeared to have, and if in that collectivity they happened to be the majority nothing prevents them from being the minority in a larger group, and so on up until a fully standardized and agreed upon average..?
Let's do some math. IF the numbers given in the video were true, then the ocean on Enceladus would be around 26-31 Kilometers deep. According to the internet, Enceladus' diameter is about 505 Kilometers. As a near-spherical object, this number applies all around the moon. The mean radius of the moon is 252.1 Kilometers. A mole of water is 18 Milliliters, at the density of 1 gram per milliliter. Oh, I found the problem. If we can find how dense the melted water is in that ocean, we can find out about how much water is in that melted planet-wide ocean. Density varies with pressure and temperature, so with such a different environment than Earth we can't yet find that number. Someone want to get on that?
yes, so if we divide the width of that moom with the diameter of the pacific ocean we would find that the exclusion of the mass that is contained within our world aswel. if we times that by 2 and divide it by 11 we would see that not only is the ocean deep on that moon but it also has alot less gravity than the surface area of our own moon, which leaves us to think that maybe the circumference times the weight will thrive as its own ecosystem
RuggedALAN We don't need the measurements of another moon to know how much water is in our oceans. And besides that, they are dramatically different environments, so their densities are likely different. To know how much water exists in THAT ocean, we would need to know the density of THAT ocean's water, which is the question I was trying to answer. I'm not trying to determine if there's life in it.
+supersmily5SS5 well to determine that we need to calculate the amount of h2o atoms in a regular 12oz bottle then we times the size of the bottle by the planets circumference divided by how many bad movies adam sandler has made.
RuggedALAN Okay, don't be a but. The density of objects like water changes with the temperature and pressure acting upon them. Because we can't determine that, we can't find the answer.
what if there was an intelligent space faring specie's on this water moon that recently sent a probe to earth and they know the planet could harbor life and they wonder Are we Alone in the universe
+indubualisticism123 Gravity has little to no input in forming life. The problem would be something chemical... like, the concentrations of required elements and compounds dissolved in the oceans.
MrFreakHeavy so then life could possibly form out in space? interesting. Well enceladus had somewhere around 4.5 billion years to accumulate all those chemicals. i hope life took hold there and we send a probe to find it in my life time. would like to be around for the discovery of aliens..
+Krazorr Landing is hard. Really hard. You just won't believe how vastly, ridiculously, mind-boggling hard it is. I mean, you may think landing is easy: humans and probes have landed on other bodies plenty of times. But really, that's just peanuts to landing on Enceladus.
+Krazorr Landing successfully is way harder than zipping by in an orbit. Primary problem is slowing down so the rover/sub doesn't get eviscerated on impact. However there are plans to send a submarine that would drill through the ice and explore the oceans.
+Krazorr Main issues with landing on Enceladus: 1. No atmosphere to slow down the probes without using fuel like on Earth, Mars and Venus (although Venus' atmosphere is so thick and hot that landers never survive more than a couple of hours) 2. What to do after landing? A small 100kg probe would have to drill a hole possibly hundreds (or thousands) of meters deep, into extremely hard ice and only hope to find water at it's maximum stretch. 3. Money! To land somewhere without an atmosphere you need a LOT of fuel (PLUS harpoons such as those which failed on that comet recently). Lots of extra fuel means lots of extra weight to get off the Earth = lots of millions of dollars.
Why are scientists so fascinated with finding water and life on other planets? What are they going to do with all that info? And by going to these planets what are they going to achieve?
Nobody has a goal during exploration. When we first discovered radio waves, we didn't think, "Yes! Wireless communication!" In fact, people thought they were useless and just a peculiar natural phenomenon. AFTER the discovery came the innovation and put radiowaves to technological use. Discovery, and the technological advancements made to reach those discoveries, is what drives civilisation.
+Murtaza M You've missed the point; again. You keep saying, "They have no reason to." We've never had a reason to explore. And in any case, the discoveries we make on other worlds will benefit us in the long-term. Get out of your short-term thinking cage.
An that's what I'm trying to explain to you. If you were actually thinking long term you would know that it's not beneficial to us at all exploring another world as we would never need to go in the future.
+Murtaza M Then you are ignorant to the potential benefits of an exocolony, and extraterrestrial mining. Also, by trying to find ways to get to other worlds, we put effort and money into furthering technology, which benefits civilisation as a whole. Space technology always filters down. Half the components in your smartphone only exist because of space agencies.
a moon the width of Arizona with oceans deeper that most of earth's? this moon sounds more like a giant water baloon with a rock inside.
You mean a colossal rocky core inside.
Deeper than all of earth's oceans, actually

What water pressure would the bottom be at on Enceladus? Since it has lower gravity but also deeper oceans.
I think you could calculate that yourself. I know the equation has gravity in it. I think it's something like p=density * gravity * height
+Twixgtx It's a bit different on Enceladus due to the crust, that will be adding allot of pressure.
+SwedishPerson Intriguing question. The ocean on Enceladus might be very different to how we think of them on Earth. It could be a viscous, saline slush... more akin to magma on Earth than a traditional free flowing liquid. I don't know.
+Twixgtx you'd need to work out g with G and Encelidus's mass and radius. Which is tricky because deep inside you'd be guesstimating on the depth of ice, and core composition for an accurate model.

Question: Would the salt content of the water account for it being there? (Rather than relying on tidal forces to explain its presence)

I've watched *every single scishow & scishow-space video to date*, but still can't get used to Caitlin's presentation style :/
Enceladus sounds like Enchiladas. Spellcheck agrees.

plain simple there are radioactive isotopes like uranium a thorium in the core

Okay, so Enceladus has water without tidal heating, and Pluto has active geology without tidal heating. What are we missing? Could this have implications for rogue planets or dwarf planets? Why isn't this process affecting Mars?
Enceladus is salty, and Pluto might have radioisotopes in it's core, but just not enough to create a liquid mantle.
If the tidal heating from Saturn is strong enough to melt all that ice would it also be strong enough to produce the friction required for underwater lightning? Is underwater lightning even possible? Are these silly questions?
Believe it or not, Enceladian geological features are named after characters and places on The One Thousand One Nights, also known as Arabian Nights.

Yeah but the morale "burn out" on the way to Mars will just arrive much later.
And my guess is that it will last longer and be more difficult.

QQ: Could you walk on water in micro gravity?

The water would be floating around.
No i mean if there was just enough gravity to keep it as a body of water, for example on Enceladus. I didn't phrase it very well
+EJGilb In any substantial gravity field (i.e. a moon) density gradients remain relative. That is to say sinking and floating depends on the density of the two objects in question. In short - no, you could not walk on water. You would, however, sink more slowly in a lower gravity field.
but if you could apply enough force on the water (since it still has mass relative to you) could you generate enough propulsion to stay sort of on the surface

They should send a playstation up and require the astronauts spend at least a couple of hours every day relaxing outside of their eating and sleeping time, or use their weekends to relax. Burnout is caused by an imbalance of work and relaxation... excessive work without enough down-time leads to burnout. They might be prestigious scientists, but they're still workers and we should all advocate for their rights.
The fix for loss of productivity is VR
Is it possible that there's a shit ton of radioactive material in the core?
Caitlyn is adorable
I hate enchiladas.
As I appreciate the amazing work put into these experiments, and I acknowledge the immense quantity of extremely useful details and results that will come out of them, I think even 10 people repeating this experiment wouldn't be a high enough number to judge for this kind of psychological studies at a world-average level, even with thorough personality checks before the game; it very well could be a minor personality trait that some of them appeared to have, and if in that collectivity they happened to be the majority nothing prevents them from being the minority in a larger group, and so on up until a fully standardized and agreed upon average..?
NOO I WANT THE BOY
Video is 4:20 minutes... well play sci-show... well played.
WATER ALIENS FTW
Since the ISS shows the earth is round why do some people think the earth is flat?
Got Enceladian fish?

Shit...
Let's do some math. IF the numbers given in the video were true, then the ocean on Enceladus would be around 26-31 Kilometers deep. According to the internet, Enceladus' diameter is about 505 Kilometers. As a near-spherical object, this number applies all around the moon. The mean radius of the moon is 252.1 Kilometers. A mole of water is 18 Milliliters, at the density of 1 gram per milliliter. Oh, I found the problem. If we can find how dense the melted water is in that ocean, we can find out about how much water is in that melted planet-wide ocean. Density varies with pressure and temperature, so with such a different environment than Earth we can't yet find that number. Someone want to get on that?
yes, so if we divide the width of that moom with the diameter of the pacific ocean we would find that the exclusion of the mass that is contained within our world aswel. if we times that by 2 and divide it by 11 we would see that not only is the ocean deep on that moon but it also has alot less gravity than the surface area of our own moon, which leaves us to think that maybe the circumference times the weight will thrive as its own ecosystem
RuggedALAN We don't need the measurements of another moon to know how much water is in our oceans. And besides that, they are dramatically different environments, so their densities are likely different. To know how much water exists in THAT ocean, we would need to know the density of THAT ocean's water, which is the question I was trying to answer. I'm not trying to determine if there's life in it.
+supersmily5SS5 well to determine that we need to calculate the amount of h2o atoms in a regular 12oz bottle then we times the size of the bottle by the planets circumference divided by how many bad movies adam sandler has made.
RuggedALAN Okay, don't be a but. The density of objects like water changes with the temperature and pressure acting upon them. Because we can't determine that, we can't find the answer.
what if there was an intelligent space faring specie's on this water moon that recently sent a probe to earth and they know the planet could harbor life and they wonder Are we Alone in the universe
i'm thinking how it would like if instead moon we had another earth sized planet
I would like to see some evidence.
Guys it's actually 4:21 lol
Is Enceladus more likely for life than Europa?
I wonder if life could evolve with such low gravity.
+indubualisticism123 Gravity has little to no input in forming life. The problem would be something chemical... like, the concentrations of required elements and compounds dissolved in the oceans.
MrFreakHeavy so then life could possibly form out in space? interesting.
Well enceladus had somewhere around 4.5 billion years to accumulate all those chemicals. i hope life took hold there and we send a probe to find it in my life time. would like to be around for the discovery of aliens..
Anti-science skeptic: "Ha! Scientists got something wrong! Told you they don't know anything!"
Scientist: "LEARN ALL THE THINGS!! xD"
why dont they just fucking land there... they have been by it many times....
+Krazorr Landing is hard. Really hard. You just won't believe how vastly, ridiculously, mind-boggling hard it is. I mean, you may think landing is easy: humans and probes have landed on other bodies plenty of times. But really, that's just peanuts to landing on Enceladus.
It's a lot easier to nearly miss something than to successfully land there
+Krazorr Landing successfully is way harder than zipping by in an orbit. Primary problem is slowing down so the rover/sub doesn't get eviscerated on impact. However there are plans to send a submarine that would drill through the ice and explore the oceans.
+Krazorr Main issues with landing on Enceladus:
1. No atmosphere to slow down the probes without using fuel like on Earth, Mars and Venus (although Venus' atmosphere is so thick and hot that landers never survive more than a couple of hours)
2. What to do after landing? A small 100kg probe would have to drill a hole possibly hundreds (or thousands) of meters deep, into extremely hard ice and only hope to find water at it's maximum stretch.
3. Money! To land somewhere without an atmosphere you need a LOT of fuel (PLUS harpoons such as those which failed on that comet recently). Lots of extra fuel means lots of extra weight to get off the Earth = lots of millions of dollars.
+turkwinif Your Avatar checks out. You know how hard it is to land. #KSP4lyf
dark energy is melting the ice.
That's not how any of this works
+Gerald Dokka I'm not saying its aliens.
But its aliens.
Shes cute
Set speed to 0.5. You're welcome :'D
Why are scientists so fascinated with finding water and life on other planets? What are they going to do with all that info? And by going to these planets what are they going to achieve?
Nobody has a goal during exploration. When we first discovered radio waves, we didn't think, "Yes! Wireless communication!" In fact, people thought they were useless and just a peculiar natural phenomenon. AFTER the discovery came the innovation and put radiowaves to technological use. Discovery, and the technological advancements made to reach those discoveries, is what drives civilisation.
That wasn't a great comparison. This is a completely different world their exploring and there's no reason to do so
+Murtaza M You've missed the point; again. You keep saying, "They have no reason to." We've never had a reason to explore. And in any case, the discoveries we make on other worlds will benefit us in the long-term. Get out of your short-term thinking cage.
An that's what I'm trying to explain to you. If you were actually thinking long term you would know that it's not beneficial to us at all exploring another world as we would never need to go in the future.
+Murtaza M Then you are ignorant to the potential benefits of an exocolony, and extraterrestrial mining. Also, by trying to find ways to get to other worlds, we put effort and money into furthering technology, which benefits civilisation as a whole. Space technology always filters down. Half the components in your smartphone only exist because of space agencies.
