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, unc
we're /enceladus/ here
>>
>>16964084
they'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
>>
>>16964073
Nothing 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
>>
>>16964073
it'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

back to /x/ with you.

You also need someone to be listening for a communication method as chimp-tier as radio.
>>
>>16964463
Yeah 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?

1000% not what that quote means you illiterate homosexual. I fucking hate it here, don't your losers read books or even watch movies?


....sigh...
>>
>>16964437
Yeah, 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.

Flat earthers act like niggers
When you start treating them as such, they act offended, tell you that you are wrong for generalising before inevitably acting like every single other one
Shitty 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 are
That shit should be ban on site

thanks for your compliment, you will never go to space btw

radiolysis 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 decompose
the 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 ocean
so you have estimates from the oxygen level of earth's oxygen minimum zones to estimates exceeding even the oxygenation of earth's oceans

if 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!!

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

Radar 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.

Most likely everyone here knows the quote. The difference is that ne provided a constructive answer to a useless and cliched quote.

>>16964172
>sparse mineral composition
How do you know? The core has been kneaded for billions of years.

>>16968929
Most 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
