@jJuvyCrim lol im the only one here

[jJuvyCrim]

@xLoneWolfICP lol what you mean

[h0tkn1f3r]

Water isn't necessarily required. All that's required is a medium in which atoms can mix with other atoms, be it liquid methane, liquid nitrogen, whatever. Stuff evolves according to it's surroundings. We used to think life needed sunlight, but we know now that's not true. I for one, believe there's life EVERYwhere. A billion different environments, a multitude of life.

[R3AN1MAT10N]

WTF? Wait. The continent "Europa" is called "Europe" in English. But the moon "Europa" stays "Europa"?! Strange. It's the same word with the same origin, thought.

[leahcimrac]

How the hell did all that water get "specifically" there? If thought the radiation from jupiter would have have a more destructive effect on the moons.

[TheSmashPot]

I believe that when the sun swells and becomes a red giant...the ice on Europa will begin to melt revealing a water world and the temperatures will cool down making it habitable to a point...we would have to puncture (somehow, though impossible with modern technology) a whole into a "shallow" part of the submerged land and let lava (if there is any from its core) build the land itself. Sorta how Hawaii was created. Farming and planting seeds may be the only possible food source from the planet.

[Lukeyyy1995]

lol they might have cod ;)

[NixFaerie]

byebye marsian hello...... europeans... maybe that's why everyone still uses marsians in movies...

[SpiderCheese101]

At first i got all exited thinking omg

If theres water theres a chance of life but then i relised, its like -150 deggrees there not alot of fish on earth can survive that temerputure :(

[Daseekr]

People are so close minded. Searching for water. Seriously you have no idea what stuff are out there yet you search for only 1 thing. Life might be something totally different somewhere. I remember I read a book with fish that lived in acid and worms that live in ice. Instead of wasting money for your precious army send a bunch of robots and stop wondering wtf is going on on that place.

[HurenSohn465]

WoooW  *_____*

[MrMushroom90]

to me a little bacteria isn't life i want to see animals or some sort of inteligant lifeform and there isnt any in our solar system. We need to stop spending on these boring missions and explore beyond the solar system

[CastleSunshine]

we will travel to EUROPA in 2028 to explore the planet

[instint07]

GAY

[nickalexrock]

just think of how expensive sparkling europa water would cost

[Ramshobraja]

We would need much more than a rover to explore the oceans of europa. We need a submersible type device and possibly manned control. Something for whic I would definitely sign up for :)

[uturniaphobic]

here's my hypothesis about Europa and in fact all the moons of the gas/ice giants:

Those giants were possibly not here from the start of this solar system. They're possibly interlopers, failed stars, roaming space until our Sun grabbed onto them sent all the rocky stuff into something close to what we see now...a car wreck. Just a thought

[uturniaphobic]

Europa is cool.

But I wonder, if scientists think comets brought water to Earth did comets put all that water on Europa? That's a lot of impacts especially for a small body.

thanks for the show!

[mikejackson4ever]

That's what she said.

[uturniaphobic]

errr.... a lot of impact for a small body....

I know a girl who gets excited when I say "coronal mass ejection"

[TachieBillano]

@uturniaphobic: It's probably more like this: as the planets of our solar system formed and evolved, comets that hit some of them carried enough material (water included) to jumpstart a natural "in-house" process (much like Earth's water cycle) on some planets (or moons) that would continuously produce water over time -- until one day, the planet or moon ended up having an ocean.

[uturniaphobic]

well some of that which you say has been theorized by others too. I'm just looking at the entire solar system body and its condition today and extrapolating what may have led to this current arrangement..

[seattlewonders]

A human don't survive 1 day at europe because of jupiters radiation

[Macjima]

If there if warm water, but no life, we could always put life there and let it evolve on its own.

[johnsmdm]

you fucking idiot....-20 is freezin...how about -430 you moron!

[Macjima]

0:53. You didn't even watch the movie did you?

[johnsmdm]

macjima, before you push out your lower lip at me give me a temperature you think is at these flexing parts...these places are so far from the sun that they are useless for life...youd freeze your nuts off daddy...-400 degrees F...you or da fishes would freeze instantly, and thats how it goes...and if Kaku wants to challenge that then come get it big boy...

[orangemarme]

agree with cosmovision

i think the same, just because our main element for surviving is water doesnt mean all the other living things outside solar system (if there is) does not have to have as the main element, it could be anything, even something noone has seen

[penguin10916]

Personally I think NASA should create a probe that can drill into the surface and transmit video footage to a beacon on the surface, from the surface to a satellite and from the satellite to earth.

[cosmosvision]

why does life in the solar system has to have water? Other life forms may breath methane for instance. They could live off other elements other than water???

[candr]

True and one day we might find something like that, but for now we can only know what to look for and detect life as we know it. If we come across another form then thats just a plus. In otherwords we know what we are looking for.

[6691alexb]

@cosmosvision

Because from what we know bacteria needs water and oxygen to to multilpay

and methane is a gas form.

[cosmosvision]

@6691alexb alright, good point.

[F19991]

Because, everything is made out of water. The first stars were made out of hydrogen, and within those very stars li3k every element in the universe was made. When those stars died, all the elements and stuff came out. But basicly they were made out of hydrogen.

Hydrogen (+ oxygen) --> Water

Basicly Life needs water because it ís water.

[cosmosvision]

@F19991 I like your explanation, but I still stand at my original thought.

[n809n]

@cosmosvision i agree. we earthlings run on water, but what if theres any species out there that run on some type of gas??? think about it guys. i would like to have the chance to meet a scientist. i would drive him crazy with all the questions.

[tfwarlord]

@cosmosvision when they look for like, they look for lile "as we know it". They dont say there isent other life, but that it would be "easier" for us to setup creteria for the search based on what we already know...

[Helge129]

@cosmosvision Because life as we know requires water for the biochemical reactions.

And there is indeed life that breathes methane, and CO2 even, but still needs water.

[BudCharles999]

@cosmosvision I agree. It may even be possible for alien life to live on molten salts.

[gibsonstrat66]

@cosmosvision i agree, but all we have for evidence is what we have on our own planet and unfortunately so far our planet holds our only example of life anywhere in the universe, since all living things we have ever encountered so far need water to live thats what were looking for, at least until we find life somewhere that can sustain itself off of something other then water of course:)



[TeenageIronman]

@cosmosvision cuz its biochemistry

[abusivepersian]

@cosmosvision There are a billion and one reasons why water is absolutely necessary for life any forms of terrestrial or extra terrestrial life. I'm not gonna list all but one the of the most important quality of it is that it needs to be fluid in a large range of temperatures and it needs to be a good solvent (aka. needs to be polar). It needs to be broken up into oxygen (which can act as an oxidizing agent). It has to be renewable/recyclable. + many many more reasons.

[peterm3964]

Is there life on marse I dont know .there is hair on it and it stinks

[jauriem]

If u can find images of europa and look closely u will find that most of the cracks on the surface are parallel to one another and that they in fact would fit together like a jigsaw puzzle. This indicates to me that there is definately liquid water under the surface ice. The ice "plates" so to speek, act like the plates do here on earth. I can imagine that at the boundries where the cracks are, there is subduction. So its like a cycle where the ice melts, wells up, and re-solidifies.

[RollenHeith]

but what about light?

[dusq123]

There could be enough light underneath ice cover.

Some creatures servive under extreme conditions.

[marlonnews2006]

Send out a robot there soon, folks. I want to see this.

[buoghuoj]

Agreed.

[Atheistjeremy]

I concur.

[dodow1234]

I second that

[capri231]

i third it

[SpiderCheese101]

@marlonnews2006 you know how we cant get to marz cause our space ship would run out of gas? thats what would happen if he tried it. its too far :(

[CULAVE]

In Newcastle upon Tyne, UK, the Life Centre (a science museum) has a special audio visual attraction- a bit like a planetarium which mentions potential life on Europa. Its worth a visit. Fascinating

[superboysky]

amazing

[Pizzagal06]

brillant!!

[aliceh260]

wicked!

[DAT28C]

cool!!
