What if the Europa Lander finds complex life under the ice of Europa in the 2040s or whenever it arrives? Imagine discovering that life coincidentally also exists so close to our planet, and then remembering that we've been broadcasting radio signals over hundreds of light years for the last two hundred years.
um... europa is in the past, uncwe're /enceladus/ here
>>16964084they're doing the enceladus lander first but there's no way they don't bring back the europa lander once the europa clipper is done doing it's job
>>16964073Nothing would happen, there are many places in the solar system that could have or did have life in the past. Actually finding it doesn't really change anything on a day to day level even if it's scientifically interesting. The biggest impact would probably be another rushed mission there again and perhaps missions to other ice moons to investigate those too.
has anyone ever thought how weird the water in these moons would be, no dissolved oxygen--because of no great oxygenation even, sparse mineral composition compared to earth, probably different hydrogen isotopes, if we drank it, would we die, would it taste the same
>>16964073it's equal parts funny, sad and frightening that people can look at this picture and think it's a real "moon" of some distant "planet"
>>16964073>we've been broadcasting radio signals over hundreds of light years for the last two hundred years.nope. our radio broadcasts fade out over distance they dont travel forever. they'd be too weak to even detect from beyond a light year. you need extremely powerful directed bursts to do that
"All these worlds are yours—except Europa. Attempt no landing there."
>>16964188back to /x/ with you.
>>16964437You also need someone to be listening for a communication method as chimp-tier as radio.
>>16964463Yeah any life found would increase the amount of political red tape tenfold. Probes would be forced to avoid whatever system to avoid despoiling the life. Finding life kills exploration.
>>16964073>and then remembering that we've been broadcasting radio signals over hundreds of light years for the last two hundred years.So what could have been done different? No use of electromagnetic signals?, how do you develop your technology without that?
>>16964073this is the resurrected eyeball of rabbi jesus, not a moon. sometimes you schizos really push the limits
>>16964084>enceladusmogged
>>169653621000% not what that quote means you illiterate homosexual. I fucking hate it here, don't your losers read books or even watch movies? ....sigh...
>>16964437Yeah, it's interesting how poorly detectable we still are. It also works in reverse, ie. civilizations out there would have to be doing something extremely noticeable and wasteful energy-wise, for us to be able to pick it up.
>>16964483x believes space is real, lolwhich says a lot
>>16965961Flat earthers act like niggersWhen you start treating them as such, they act offended, tell you that you are wrong for generalising before inevitably acting like every single other oneShitty facebook meme spam, purple prose, lack of understanding of basic physics, math, perspective and common sense in general, spamming links to 144p videos anyone that interacts with them knows how fucking retarded and annoying they areThat shit should be ban on site
>>16966007feminine reply
>>16966017NTA but let's be real, being insulted by someone with extra chromosomes is a compliment. You can't win here, little tardo
>>16966019thanks for your compliment, you will never go to space btw
This board is fucked
>>16966017Niggerly response
>>16966576nice attempt christcuck but ni**ers believe in space, see also the latest black astronaught
>>16964172radiolysis from jupiter's magnetosphere produces hydrogen peroxide and oxygen from the surface ice (this was detected spectroscopically) and the theory is that since the ice sheet seems to undergo something like tectonic behavior, when a plate subducts to the ocean and melts the oxygen will be released and the hydrogen peroxide will decomposethe problem though is that nobody knows the thickness and dynamics of the ice sheet, and also i think its unknown how the surface contaminants and environment etc would influence the ice structure's ability to retain the gas and also how much makes it to the oceanso you have estimates from the oxygen level of earth's oxygen minimum zones to estimates exceeding even the oxygenation of earth's oceans
Herpa derpa
>>16966675if it’s water-ice-water, there’s nothing. if it’s water-ice-rock, then something is possible, but maybe just battery acid. but europa is so 2010 and at least enceladus has geysers spraying its ocean out into space where we could reasonably manage to sample it. now all they just need to figure out is how to LAUNCH A FUCKING MICROSCOPE INTO SPACE FOR THE FIRST TIME EVER!!

>>16964073>we've been broadcasting radio signals over hundreds of light years for the last two hundred years.Radar is brighter so if someone out there is looking at the right time they'd see it much more clearly. But biosignatures should be visible to anyone within 50 light-years. We're close to being able to detect the presence of life on earthlike planets with JWST. Nearby aliens with something a little better would be able to tell that there's life on earth. Discovering evidence of life on another planet or moon in the solar system would mean life in another star system is far more likely than not. There's about a few thousand star systems close enough to see our biosignature so they'd know something is here. I believe it is likely someone may have already tried to contact us. There's many "wow! signal" events that are categorized as terrestrial noise based mostly on a believed low probability of extraterrestrial source. Discovering life on Europa flips that around, more likely than not we've already recorded a few technosignatures
Did you fools not watch the movie? Don't fuck with Europa.
oof
>>16964437Radar systems, especially military radars, were up to the 1970s extremely powerful. These will probably be first to be noticed by an alien civilisation. Only later did the military think that Low Probability of Intercept radars would be a good idea, so these days the emitted power is a tiny fraction of what it used to be.>>16965877Most likely everyone here knows the quote. The difference is that ne provided a constructive answer to a useless and cliched quote.>>16964172>sparse mineral compositionHow do you know? The core has been kneaded for billions of years.>>16968929Most likely, the body started with rocks, built up enough gravitational field to gain more rocks and then water ice. The entire are is full of asteroids, some were captured by the gas giant, many were swallowed by their moons.
Fuck off
How about no
>>16971474How were they not getting irradiated to death the whole time they were on the surface
>>16964073We learn what ayyfish are edible and what aren’t.
>>16964073There's no europa lander planned. Unless a lander sees fucking frozen fish on the surface, there's not a very high chance it'll detect life>2040sLol. 2050s>>16964084Enceladus can support the biomass of one blue whale. That's fuck all
>>16964073>>16964084>>16964084>>16965848Someone did a paper which put forth that Europa might not have the hydrothermal vents for life the way that Earth did but Enceladus might. Triton might also be another candidate and seems like a really interesting moon but I doubt we'll see any probes going their in our lifetime.
>>16977528I think it was a combination of some water shielding plot device in the ship and a good landing spot so the ice formations limited exposure. The leading hemisphere of Europa also receives less radiation than the trailing hemisphere from Jupiter's magnetic field.
>>16964463DID THEY NOT READ THE BOOKS?!?! WHY ARE THEY ATTEMPTING LANDINGS THERE????QUICK SOMEONE FIND FRANK POOLE HE'S FLOATING OUT SOMEWHERE NEAR PLUTO.....AHHHHHH FIND DAVE AND HAL AND SAVE US FROM THE MONOLOTH FRANK >t. has read 2001, 2010, 2061, and 3001
>>16964073>>16978210Why does it just look like a dirty frying pan?
>>16978996First image is Europa and second is Triton but I suppose they both look like dirty frying pans
Someone nuke this thread
>>16964089>doesn't really change anything on a day to day levelyeah so did inventing hydrogen bombs but its still a big deal
>>16964073kys
>>16987549NoI was here first
>>16965848What's going to live at 24 MPa?
>>16964437>fade out over distanceThey spread. Square cube law. They are photons. They cannot lose energy.We can detect neutrinos, why would some hypothetical more advanced peoples not be able to deduce a specifically polarized, specific wavelength of specific eV photons above background coming from a specific direction?
>>16964188lol
Why so angry anons?
>>16964188You’re retarded. You also ruined this thread.
How are they going to drill the ice layer that is 18 miles thick?
>>16964073Big fucking deal, you will get used to it pretty quickly and the novelty will wear off. There is a planet with life on it, there are trillions of other planets... Who could've guessed that there would be life on another one too! Exciting!We already have "alien" creatures on earth but I bet you don't bother studying their biology all day like you should be. People obsessing over aliens don't even care about comb jellies that can age in reverse and all the crazy stuff that happens in the ocean, we already have aliens here and you don't bother extensively studying them.
>>16995957
>>16964073Unless the clipper sees the signs no lander. If there is any life clipper will detect it. That’s it. Ganymede is also getting scanned. Juno is checking other places. Jupiter might actually have life but we don’t know
>>16996739>Jupiter might actually have life but we don’t knowDo you mean one of it's moons or Jupiter itself?
>>16964073What are those crisscrossing lines
>>16964073the whole thing is completely covered in ice. there would be no life besides maybe retard glowie fish and little clamthings in tubes, and theyll all be variations of species we have on earth because everything is the same and boring everywhere.
>>16964089>actually finding it doesn't really change anything on a day to day levelEuropan Jewdolphinoid flippers typed this post

>>16995957Maybe he did, but he did so hilariously. Props to him for managing that with only ten words
>>16964073If anything lives there at all (a big if) it will be concentrated around hydrothermal vents.
Indians everywhere.
>>17002166people shitting on the street you know they just don't care
>>16964073Lol
Fuck off retards
>>16964073Life on Europa would be cool and all but if i'ts barren how should we utilize this leviathan's den ripe for the plundering? I think we should unleash some of our stuff down there; bit of krill, phytoplankton, and sharks of course. Try to create our own ecosystem from nothing, see what happens.
>>17005852how are phytoplankton supposed to live in the dark?
>>17005873They will be genetically engineered with future science to live off the dark instead
>>17005852Can you fuck off
>>16964073>All of these worlds are yours. Expect Europa. Attempt no landing there.
>>17007601You need to make better use of your limited speech pool anon. Why should I fuck off about this? Humanity will inevitably do this if we find Europa is lifeless. The thing is a cosmic egg, and if it's unfertilized then it's our duty to plant our seed there.
