Could There Be Life On Jupiter's Moon? | Solar System | BBC Earth Science

What he says in the last few seconds of this video. That IS profound and... chilling.

[@cwwiss1]

No. The Milky Way and all the suns and planets were built from the same stuff at roughly the same time. It would be totally illogical to even propose that there are no other civilisations like ours in this galaxy. However they may be a couple thousand light years away which effectively makes them unreachable and in that sense we are alone.

[@ogelsmogel]

The Universe is bustling with life, the only problem is that we're too far apart from each other.

[@adamstevens6299]

Given the vastness of the cosmos, and the fact that we’ve likely only discovered a tiny fraction of its true expanse-which might even be infinite-I often wonder if life could exist based on a completely different set of components, fundamentally unlike what we consider essential for complex life.

[@Pizzasalladland]

I cant wait to see this on Swedish streams. I love Brian Cox and his documentaries.

[@otpyrcralphpierre1742]

Finding life elsewhere, even microscopic life, will answer the fundamental question...."Are we alone?"

[@Thomas-vn6cr]

Imagine if we find aliens and they're also looking at us realising they've also destroyed their planet but at least we answered the question so we can stare at them and do nothing else.

[@mattybold6726]

​@@Thomas-vn6cr you miss the point of discovering the existence of life. Earth is literally the ONLY place we've recorded life. Haven't even found a single organism anywhere else ever. Nothing. Anywhere. As far as we know, we are the ONLY purpose in the entire universe. On earth, we have hydrothermal vents so deep in the ocean, no sunlight can reach it. But there is microbial life down there. Against all odds, there is life down there. But none has been found in similar conditions on other planets. Nothing. This goes deeper than your assumption we're just staring at them and doing nothing

[@Rydonattelo]

If we find life on Mars or Europa and it developed separately from us on earth, a separate genesis then that would be staggering. That would indicate there was life absolutely everywhere, over all solar systems. If its the same as us, the same genesis then its been trans spermia were either we came from that or that came from us at some point then we would be back to square one. It's possible it's just our solar system. Then we wouldn't know any different for a long, long time. Maybe never.

The most scary thing is if we are really alone, all these billions of galaxies life is only present in a single small fragile planet, and yet we are killing each other, no one can help us but ourselves.

[@adarob92]

If so, then good riddance.

[@thathaslage]

I can't really describe the feeling I get when I try to imagine a scenario where breaking news shows images of an alien ecosystem with complex life and food chain. Could you imagine? I almost get an adrenaline rush over the implications of what that means. Just a single cell organism found off Earth would have the same effect on my emotional state though. It would mean life is spread throughout further than our minds could ever comprehend. 🤯

[@tullimonstrum52]

Fingers crossed it happens in our lifetime🤞 it would be unreal

[@krist6074]

The fact that the Earth went through several mass extinction events and recovered every time should give us hope. Personally, I truly hope they find bacterial life in these water plumes that Europe Clipper is aiming to fly through!!

[@pegatrisedmice]

There should be a disclaimer here that we barely figured out how to send a probe near Europa, and we literally have no idea how to dig through that ice layer and get meaningful data back. So Europa clipper will arrive there in 2030 with no plan of digging beneath the ice. With this rate of progress, the most surprising thing would be that we even figure out how to look for life there.

I think life is EVERYWHERE in the vast universe. It's just the technology to travel such vast distance is REALLY HARD. If the universe start from big bang, then logically life all over the universe start around the same time. And the technology in other planet is more or less is the same.

[@nufan4521]

You forget to figure in the dinosaurs who existed for millions of years prior to us being here. And in the scale of time, we have been here only a second or two. Imagine a civilization that never got wiped out with that many years ahead of us.

[@noelchignell1048]

I suspect that boring microbial life is fairly common but complex multi-cellular life much less so and technologically advanced species extremely rare. Only happened once here on earth after billions of years

In the current world situation, it would be more wise to prevent losing life on earth, especially on war zones.

[@dougclark9921]

Might be worth letting us fizzle out and letting life elsewhere have a go

[@tsunamix0147]

The only issue with discovering life on Europa is getting into the 15 mile-thick (yes it’s really that deep) ice sheet without the water underneath escaping into the vacuum of space. If a cryoprobe and its underwater probe are able to penetrate the ice sheet, they have to be able to have a method to stabilize the space between the vacuum of space above, and the icy waters below.

[@kieranmilner4208]

If it’s melting its way through the ice the water that vaporises will just turn back into ice after going so deep down the problem is how to melt it since we could use radioactive isotopes and a dill bit heated by them but then risk it breaking the capsule and spilling the isotopes into the planet

[@SgtCake101]

And how do you propose we do that?

[@ziploc2000]

Vacuums don't suck. Gravity holds the water down.

[@lewis7515]

The water is not going to, "escape" - it's only there at all because of gravity. If a probe makes a relatively tiny hole, (and even if the hole doesn't get plugged behind it), any water that does rise behind the probe is unlikely to make the surface - it's going to freeze over the 15 mile distance it would have to cover to get there. Even if that water does somehow reach the surface, it will find that the highest temperature on Europa is -130°C: it's going to freeze in a moment. Even if it takes a month to freeze, only an insignificantly small amount of water will evaporate... If Europa was going to lose a meaningful amount of water, it would have done so, by now. We could make 10,000 holes, all over it, we make will make no appreciable difference whatsoever to the volume of Europa's ocean.

[@pumpkineater23]

They'll require a nuclear-powered drill capable of both cutting and melting its way through the ice, reaching depths of around 5 kilometers before resurfacing. At this point, a robot will deploy a specially designed 90-megaton ice-obliterating explosive. This detonation will clear sufficient ice to initiate the next phase.. the deployment of the nuclear-powered submarine drones. These drones will dive into the depths, searching for signs of life, analysing the water's composition, and investigating potential hydrothermal vents. Such a mission could revolutionise our understanding of extraterrestrial oceans and the possibilities of life beyond Earth.

There either is or there isn’t alien life in the universe, both concepts are equally frightening…Arthur C Clarke

[@rohullahkarimi744]

Maybe the defintion for life for our species be water, energy and the chemical ingredients but we don't know what is exactly life and how does it work, maybe this is not the right question that we ask. 🤔

[@cybermonkeys]

Thank to Physics for teaching the facts. A *theory* is the initial supposition, we then calculate the consequences of these ideas against observational data and experiment. If everything holds together, then we can temporary conclude that we've established a fact. Always being mindful that new data may require us to re-evaluate the theory. It's called *Model Dependent Realism.* *These are the facts:* *Lunar tides:* The Earth is in orbital motion around a barycentre with the Moon, and the tides are caused by the gravitational interaction with Inertial forces. Gravity is an inertial force. *Solar tides:* The Earth is in orbital motion around a barycentre with the Sun, and the tides are caused by the gravitational interaction with Inertial forces. Gravity is an inertial force. *Europa tides:* The moon Europa is in orbital motion around a barycentre with Jupiter, and the tidal heating is caused by the gravitational interaction with Inertial forces. Gravity is an inertial force. If we devote the time and attend some real courses in *Physics.* Then, hopefully one day, we all might become respected *Astrophysicists.*

[@cherihubbard8172]

Im more worried about the hand prints on the tents windows

[@lewis7515]

It's just as likely as anything else that there's no Life anywhere, but here. Even if there's Life somewhere else, it's so far away that we're probably never going to be able to find it, nor prove it - so it may as well not exist: and even if we did, by some miracle, find Life at a distance, we're not likely to be able to go there, so that would only trade one kind of loneliness, for another... The sooner we just deal with all that, the better off we'll be.

[@otpyrcralphpierre1742]

Yes, this is true, but you must realize that finding life elsewhere, even microscopic life, will answer the fundamental question...."Are we alone?"

[@lewis7515]

@@otpyrcralphpierre1742 Of course I realize that - I only say that the expectation of that, is wrong. The question is too often approached from the perspective that the microbe must exist, we just haven't found it yet - because, "probability". When the reality is that what we consider probable is really our business - that's a human conceit. We can't even calculate the probability of ourselves and have no actual clue how we got here: were not actually in a position to talk about probabilities of Life, elsewhere. The exact sequence of events required to allow Life, here, might be so statistically extreme that we're actually an unnatural anomaly that shouldn't exist, at all! We don't know enough about exactly how this stuff we're made of actually came alive - if we did, it could be that would tell us the chain of events, at the right time, in the right order, for the right duration, that made us possible are of an order of probability that means we should be lucky to see Life once, per Universe - or once in every 100 Universes: or once in every 1000...We don't know. While we don't know, it's actually just as possible as any other outcome that we're totally and absolutely alone out here - regardless of how many billion Earth-like planets there may be.

This is an emotional plea. There could be life!...Let's all hope! There needs to be an energy source. It's too far away to get anything significant from the sun.
