Uncover the secrets of potential extraterrestrial life! Dive into the mysteries of Mars' past and present, exploring Martian extremophiles and the tantalizing possibilities lurking beneath Europa's icy surface.

I hope that within the next twenty years or so that they send a probe to go through Europa's ice mantel. It would be amazing to see something swim by it's underwater camera.
All we know about life is from life here on Earth, all from the same ancient ancestors. Finding life from just 1 other line outside Earth would be the greatest discovery Humans have ever made.
the word extremophile is kind of human centric. We assume, that the conditions we live under are "normal". in a way, we are extremophiles, I mean we live in an oxigen rich envirement
Imagine a society of artificial intelligence who exist as biological technology, are self aware, live forever and create species like the human race as a hobby...🛸
Thats pretty much the only solution to the fermi paradox. The difference between that and us being able to become an interstellar civilization are basically just that. Per the fermi paradox it looks like that may be just a leap too far, so far. We really come at the very beginning of the universe. There are trillions of years of habitability left in the universe. By far most life will come in the future. The thing is if we or someone else doesn’t do it “soon enough”, eventually, future civilizations will come that are not able to ever know what we know about the universe as it will literally have spread too far away for them to ever know. The knowledge we have now about the universe will be invaluable and impossible for far future civilizations to ever be able to discover. Most civilizations that come around will never be able to have known of other galaxies existences. They’ll have little reason or ability to explore.
With the shear size of the universe we can surmise that there must be life elsewhere. Mathematically speaking it’s nearly a certainty. That said, until we find it, it’s still not there. I for one am very hopeful that we find some near us.
Intelligent, space-faring life is likely SO rare that even if you believe there are 50 civilizations at any given moment in this galaxy capable of it. The laws of physics, the hostility of the interstellar space, and the sheer size of the distance between stars, makes it rather likely that at this point in the universe, no alien life has ever met or even learned of any other alien life. Ever. In the universe. Fortunately we happen to come at the very very very beginning of the habitability of the universe, relative to the trillions of years left of habitability in the universe. Unfortunately no one probably ever makes it out of their solar system, so we will never know before this star goes kaboom. Interestingly, if it does happen, it will happen “relatively soon”. As far future civilizations, when most will exist, will not be able to learn of other galaxies or the universe the way we can now as the evidence will have faded literally too far away.
Maybe most life exists in internal oceans and has to massively surpass our levels of technological achievement just to have the ability to drill out, let alone travel through space...
The ice shell moons (like Enceladus or Europa) are a good bet, but maybe even deep underground on Mars. If I was a gambler I’d wager that simple life, bacteria and whatnot, currently exists elsewhere in our Solar System. I think bacteria may be somewhat common in the universe, but more complex life is much less common. Civilizations, even rarer still…
Is there life in our solar system other than life on Earth? Maybe. Is there intelligent life in our solar system other than life on Earth? Definetinally not. What about in our galaxy, Milkyway? Maybe. Distances just are so vast when that intelligent life contacts us, it might be allready gone dead when we get thw contact. For sure, we're not alone.
And if there is this much potential for life elsewhere in our solar system, it's all but inevitable that life exists elsewhere in the galaxy, let alone the entire universe... whether or not any of it encounters each other before extinction is another matter, because I think that the Fermi Paradox's "great filter" is interstellar travel... and I don't think such travel is compatible with biology, or at least with biology as we know it.
I agree, interstellar travel may be virtually impossible for organic beings. But I think civilizations are probably also EXTREMELY rare, even at the scale of the universe. The likelihood of two civilizations existing at the same time, in the same galaxy, and close enough to transmit radio between the two is more than just a little unlikely, the chances are insanely slim in my opinion. Unfortunate, I always wanted to walk into something like the Mos Eisley Cantina and look at all the weirdos hanging out, but that’s just not in the cards.
Does anyone know how i can find a list of all of simons currently active channels? I have a feeling there are some i am not subscribed to. I only found Astrographics today (january 2024)
isn't multi-cellular life inherently 'complex'? Tardigrades are microscopic, multicellular, eukaryotic...are they not via their multicellular structures 'complex'? Caulerpa, Gromia, Valonia genus (of alga/amoeba) are macroscopic, eukaryotic BUT unicellular...are they complex (because of their macroscopic/eukaryotic nature), or not (unicellular, despite being eukaryotes/macroscopic)? Unfertilized Ostrich Egg Yolks are single cells, but if the egg is fertilized it will ofc become multicellular. Definitely complex, but not the only way complexity exists.

“lunar” = “from Luna” = Earth’s natural satellite, not any other planet’s. A hair splitting annoyance which I also share with calling all stars “suns.”
