Mars used to have running water. There's a very good chance there was once life there and may be microbial life or something remaining.
what if like… the aliens were already there and we're just detecting the particle remnants of their destroyed civilization? what if we missed our chance to make contact with extraterrestrial socialists?
very unlikely anything survived even if there was, any liquid water would be far too salty and would be deep underground. Venus is far more likely to have life, plus it almostly definitely had water oceans too in the past.
Venus is more likely to have life, but life on Mars would be easier to detect, landers last an hour on Venus at most.
Extremophiles exist on earth, and there are likely microbes frozen at our poles. It's plausible that some basic life could be living dormant on Mars.
Venus has a car crushing atmosphere,red hot rocks and a rain of molten lead and sulfuric acid. There's nothing on venus.
Only on the surface, not the upper atmosphere.
That's bad for us but it's possible something can thrive in that environment. Shit evolves to suit its context.
If there is life on Venus there is also probably life underground on Mars and in the Titan's water.
And yet as of now the odds of there being microbial life on Venus and not Mars is much higher. Would be interesting how this changes our understanding of the Universe if we find evidence that life is simple enough to produce that not only is there another inhabited planet in our own solar system, but it also exists in much more hostile conditions than Earth ever presented
Reminder that everything we know about Venus is thanks to the soviet space program.
It was also the first human probe to land on another planet.
that's just a pic of California
Soviets had confirmed this 60 years ago.
Also lol at this response.
Sadly no space comrades evidence yet.
At least the phosphine seems to prove in a way that it's very likely that there is life in the high ups of Venus' clouds. But as other anon said, it's pretty difficult and there are more close plans to go to Mars than over there.
WERE ARE YOU SPACE COMRADES!
CHINA HAS AN ARRANGEMENT WITH THE AYYS TO DEVELOP THE PRODUCTIVE FORCES TO REACH INTERSTELLAR COMMUNISM?
I thought california was red, not yellow.
Handy video for anybody wondering about conditions in Venus' upper atmosphere and why it's so different from the hellish conditions on the ground.https://www.youtube.com/watch?v=gJ5KV3rzuag
Didn't the idea of going to mars really start with the John Carter series?
What’s the point of manned space missions again? I’m fine with sending robots to other worlds for scientific research but sending humans into space seems pointless. Every single place in the solar system besides the Earth is completely inhospitable to human life and we'll never be able to colonize it.
Terrible news for the great filter if life is easily evolved.
Could also mean that life is only common around stars similar to our own sun.
That's still too many for comfort.
Great Filter is a meme. The signals we've sent from Earth have almost entirely dissipated before they even leave the greater solar system because of the distance and amount of matter scattering them. Unless you are purposefully beaming a focused signal in a certain direction there's no reason to think it would be visible.
There's also multiple potential Great Filters (assuming the theory is correct). The formation of microbial life probably isn't it, since it seems to have formed on Earth very early in our history. The real leap in evolution that kickstarts increasing complexity seems to be eukaryotic and multi-cellular life. It took around a billion years for life to emerge on Earth, followed by ~2.5 billion of simple microbial life. In the last billion we've gone from prokaryotic cells to human civilization. This seems to point to the transition from single celled to multicellular life as the real hurdle.
Soviets wanted to go into space for the sake of humanity
Americans want to go into space so that rich people can escape from Earth
The great filter is Rightism.
The great filter has to destroy all life, otherwise the galaxy should have already been converted to networked dyson swarms.
I'm surprised that pics this high in quality could be captured at that time by space probes millions of kilometers away.
it's just sending a radio signal, same tech that plays music
David Graeber thought the Great Filter might be "simulationism" or the tendency to isolate and focus on our drives instead of follow them to the "logical" conclusion. E.g. we have a drive for sweetness because eating fruits is good, but we have created sugary food to simulate what we evolved to want. Another one is that we like to make science fiction to entertain us and scratch the itch for technology and innovation.
It's as >>3426
but those particular pics are colorized I believe.
Hypothetically if you were to turn on a radio in the Alpha Centauri star system would you be able to pick up any signals from Earth or is it too far away?
Just imagine spending billions of dollars to build machines and rockets to find bacteria on nearby dead planets… I mean. who cares? what does it matter? We know life can exist on other planets so that's not really anything new.
Yes but you would just be picking up signals that were sent out 100 years ago.
>>3432>tfw the ayys would think the USSR still exists
Bruh Alpha Centauri is only like 4-5 light years away. A listener there now would be getting broadcasts from 2015-2016.
its probably just bacteria
I would be curious if alien lifeforms have DNA just like us, or something completely different from DNA that actually functions in an identical or very similar way.
DNA is actually kind of mysterious because we don't actually need the 4 bases. 2 would be enough. So you could have a DNA with only 2 bases or with a different 4 or more than 4. There might also be a different way of solving the same basic problem of storing instructions for biological processes.
uigha that site is reddit-tier. there are multiple different ways phosphine can be generated by natural activity, for example the reaction of metal phosphides with water or an acid (venus has sulfuric acid clouds and a lot of metallic iron in meteorites has a decent percent of phosphorus dissolved in it as nickel/iron phosphide). still interesting, could tell us about the geology there and shit but its probably not life. even if it is its only gonna be bacteria.
if launch costs get really cheap asteroid mining and solar power satellites would probably be profitable enough to have some o'niell cylinders for the people working there but yeah until that happens not much point for anything manned besides the ISS and maybe a moon base
Life uh finds a way.
if its legit it would be pretty useful for biology
People said the same kind of thing about all kinds of discoveries including the ability to generate electric current.
We need to consider military expenditure and advancement if alien life turns out to be common.

Space-stations might one day become cheaper living arrangements, rising per-capita energy consumption may push people outside of planet atmospheres.
Venus is a communist planet. See the ubiquitous five point star, DeRerum Natura, Julius Caesar, Mo Zi.
Anyway, life is everywhere dormient, but only in few circumstances she can express herself i the way we normally recognize her; for her being the immortal seed from the real universe lost in this dead prison.
>>3427>Another one is that we like to make science fiction to entertain us and scratch the itch for technology and innovation.
you're an idealist now
Mars is red and almost sounds like Marx. When we establish communism, we will rename it accordingly.
>>3397>any liquid water would be far too salty
I wouldn't be so sure. Scientists found microbes in Don Juan Pond and microbes are found in aquifers all the time.
It took life billions of years on Earth for intelligence to evolve. Life is very different from intelligent life.
thanks, I watched the first minute and already feel dumber
this sounds dumb as shit at first but once you actually start reading about it its basically the only way for people to expand off earth, you can build ones miles in size with just steel or aluminium and spin them to fake gravity with centripetal force so you can make them reasonably earthlike in terms of someone living inside one in terms of "gravity"/air/water. plus due to how easy it is to exploit solar energy in space manufacturing costs for the raw materials needed to build them would be much lower than on earth
It could even be that the microbes originally came from earth, carried to venus via dirt ejected by meteor strikes.
if this is real (again, i'd guess its not) there is a good chance its related to earth life. there are a pretty large amount of meteorites that were originally from mars before getting blown off into space by large asteroid impacts and then hitting the earth without being melted or anything, there is a good possibility that the same thing happened with the earth and any bacterial spores or whatever that survived might be able to survive on venus, or even the other way aroundhttps://arxiv.org/abs/1608.00706
venus could have had oceans up until a few hundred million years ago so its not completely impossible
still this is probably due to some weird volcanism or something, iirc there was something similar to this with methane being detected in the atmosphere of mars but now the general consensus is that it is from some weird reaction between subsurface water, olivine, and co2
The phenomenon we call life is an inevitable result of the laws of physics and chemistry and it is likely abundant. Multicellular life might be rare, and intelligent life is probably obscenely rare.
>>3458>we call life is an inevitable result of the laws of physics and chemistry and it is likely abundant.
Very big if true
what if it was seeded from earth from a meteor impact or something
I remember when I first saw this mindblowing photo. It was before I was a leftist consiously and i was mindblown that this was done so early in the history of space exploration.
It's probably fake.
It’s all about the organized dissipation of energy

Learn how space cameras work. They are coloured but in the same way earth cameras are.
Each "black and white image" is an image capturing a certain spectrum of light, or colour. Multiple images of the same scene are taken with multiple colour cameras, and those images can be compunded into a full colour image.
Meant to say "but not in the same way earth cameras are".
Why? The probe is still there as a visible pile of scrap up there. Plus taking and then uploading a few Mb of image is not that hard.
Imagine if the USSR lasted long enough to send probes to the outer solar system
