Planetary scientists from Freie Universität Berlin have published two new studies with promising discoveries about the potential for life on Enceladus.

Life starts deep in the Enceladus ocean, gets jettisoned by the plume, parks on Saturn's rings which becomes a huge distribution mechanism. If one extremophile reaches there, it means we could find not only a source of life but a mechanism for panspermia.
It is believed that the giant planets all develop and lose their rings over time, each time a moon is eaten. If the plumes are caused by Saturn's gravity perturbing the planet, it makes this mechanism highly plausible in all sorts of systems that have giants (and we know there's a lot of them).
Truth is, we don't know enough to take any filter hypothesis seriously.
This will not be in 10 or 30 years. But in 70-100. Maybe robots are the future life form the universe "sees" here so something finally can reach outer space from here.
And I think its very likely that other civilizations aslo killed themself by inventing AI some day in their time.
Though, Claude is the best tool ever for me :)
That was absolutely terrifying.
However, it is also likely that the places where living beings can evolve into something more complex than bacteria are only a very small fraction of those where life exists.
There are chances that life might exist on one or more of the satellites of Jupiter or Saturn, but it is pretty certain that it cannot be more complex than bacteria or at most protozoa, because on Earth the evolution of big multicellular living beings was conditioned by the development of the ability to extract energy from solar light.
Without solar light, the maximum rate of energy production is from methanogenesis, which would not sustain any big living being.
Solar light is too weak at that distance anyway, and life, if it exists, is burrowed at depths where the temperature is high enough, where any light is likely to be completely attenuated.
It might not evolve into something very complex, though.
I suspect that you won't be swayed by the abstract benefits of intelligent life on Earth finding not just proof of life on another body in our solar system but actual life that we could perhaps even launch retrieval missions to return to Earth for analysis so I won't talk about Darwin and his voyages and the theory of evolution that it resulted in as people often do in these conversations.
Instead I'll ask you what you think the dollar value of studying and reverse engineering an alternate or similar biochemical system survives in a world totally different than our own. What sort of applications could this have in materials science? What kind of new materials could we discover from alien life? What kind of novel bio-mimetic applications could we derive from this?
I look around the room I'm in and I see a hardwood floor, I see a differnet species tree making up woodpaneling on the walls. My clothes are made of cotton and rayon, there's some sort of grass woven lampshade above me. books made of paper, paintings with linseed oil paint -- what's the commercial and cultural value of all that stuff to our species?
It's not a cool concept to write scifi books about, but it may still be the reality we live in.
The most likely situation (by many orders of magnitude) is that the only practical way of getting to another star system, even in the far far future, is a generation ship travelling 50+ years one way with a significant risk of people dying from organ failure or cancer along the route. This would represent a 1000x speed improvement over current tech and is only a factor of 10x slower than lightspeed.
It is entirely unfeasible for any company or even government to spend money on such a project. Even if the ground on the other planet is strewn with diamonds and gold and the elixir of eternal life, you are looking at ~200 years before any ROI can be realised.
there's far too much unknown about the origins of life to say we even have a basic guess as to the probabilities of life
After all, everyone involved can just say it's inevitable! If we don't do it, someone else will.
It is called enlightenment and the discovery of knowledge. Otherwise, we would still have been running around with pitchforks and flaming torches, waging crusades in the name of one deity or another.
Besides, humans spend $50 billion or – equally arguably much more – killing or trying to kill each other. If that gets spent on new discoveries and knowledge, it becomes apparent that the $50 billion investment into science is a substantially better value proposition.
Serious answer: on a yearly 130T$ GDP at least a good third is spent on destroying this planet. 50$B which ends up paying phds is barely one peanut.
