Bacteria can and has survived in zero atmosphere space conditions. In 2010 they scooped up some bacteria from an English cliffside and lashed it to the exterior of the iss for over a year. It survived just hunky dory. Bacteria is currently thriving deep within oceanic vents, deeper than we can reliably observe. Also high up in the atmosphere (6-25 miles up) there's bacteria just floating about in below freezing, high-uv, low oxygen environments. My point is that living organisms are assuredly propagating elsewhere in the universe, but like the majority of life on earth it's tiny little specks that are hard to personify Edit: that doesn't mean we can't insult them over the radio.

Parallax Scroll posted:i agree that it's unlikely, but europa's nearby enough that we may as well look If we can look with remote instruments, i agree. I don't think we should send a probe under the ice, if we can drill thru it anyway. If there's life, who knows what delicate state it would be in. Early life on Earth was just blankets of bacteria. shitloads of bacteria. so much bacteria some of it has fossilized and it just looks like funny looking rocks. if a probe crashes into something like that who knows what kind of die-off would be triggered. I hate the idea of disturbing an ecosystem too. but it's hard to reconcile that with the fact we're likely to find nothing, so why be that cautious? I dunno.

It's a fun fact that Europa missions have much stricter sterilization requirements than missions to other places, because we don't want to finally arrive there looking for life only to see that oh, it's just a bunch of earth bacteria that hitched a ride on an earlier mission.

hemophilia posted:you need a biosphere that won't shred amino acids and shred simple lifeforms with horrible radiation, cook them with heat, or destroy them with weird chemical reactions, and I dunno tidally locked planets don't seem to fit that bill. They don't know if it's tidally locked and are just assuming it is. With certain systems 3:2 resonance(Mercury) or maybe something like 5:2 resonance is more energetically favourable, if that's the case here this planet would have a ~100-180 hour day. This planet is 1.3x Earth mass so could have an atmo like Venus and Earth do, is zooming around a low powered poo poo star so rads may not be a problem if it's stable and doesn't randomly blast poo poo out. It's also apparently 30c on the hot side and -30c on the night side, no idea how they're know that though probably just making poo poo up again.

I think they're exaggerating a bit when it comes to Europa and contamination. Jupiter's radiation will sterilize anything we send over there pretty quick I think. If anything survives I assume the probe would be able to do some kind of genome test and it will be easy to distinguish between Earth life and something else. Plus the chance of contamination is a minuscule issue when you compare it to the fact that I might die without ever seeing a picture of what's beneath that ice ! All these missions to Mars and even Pluto but nothing to Europa even though they just sent a probe to Jupiter to survey it's north pole (WOW super exciting stuff you dumb scientists). I want my tax dollars to be used for entertaining science too, nut just the other kind.

Sunshine is dope afGermstore posted:"orbiting something that outputs energy" is a pretty low bar to set for habitability. The habitable zone in this context means 'distance from the star where it is not too hot or too cold to sustain life.' It's not a super high bar to begin with... and that's why the habitable zone on this star is like 1/20th of an AU. As far as the tidal locked thing goes there's not much reason life couldn't be just fine in the twilight band or whatever it's called.

Sunshine is dope af and every movie for the 5 years following its release used its OST for their trailer musicduck monster posted:When we meet the gray aliens they will know us onfly for our media. it's okay contrary to popular belief that poo poo doesn't just exist forever. the signal degrades and becomes indistinguishable from noise and background radiation pretty quickly actually. Prolly wouldn't even get much past the closer stars (iirc the distance). Also prolly why we haven't heard peep from anything anywhere despite the size of the galaxy and universe.

I hope SETI is pointing some antennas over there now. Also with the new James Web telescope we'll be able to actually get an image of the planet. How cool is that ! And to think that the Government almost didn't approve of it's construction. I'm glad we're still throwing money at the F-35 though.  Those Lockheed engineers who worked on it deserve to be harvested for organs.

Yeah you wouldn't know the surface temp reliably but you could spitball approx. hot how it would be given no atmosphere or a normal atmosphere fairly accurately. Decebal posted:I hope SETI is pointing some antennas over there now. It's really a crime how much we spend on useless poo poo like F35 while NASA's budget gets dicked with nonstop.
