The Past And The Future Of Europa

[@ziitonhabsburg4821]

Dreksler Astral, you're awesome. Keep on doing it. You make everyone's days.

I love him

You always came out with great video. Thank you so much.

Europa, my desire. The one chance in the Solar System where we could not only find life, but complex life.

[@ekszentrik]

@@monke6550 It may have life. But keep in mind, the life-conductive processes happen on the Ocean floor, and Enceladus has much less floor than Europa and exponentially less than ancient Earth. More importantly, Enceladus can't have complex life because it's too young. The body is just a few hundred million years old. Not enough time if you want to have actual space deepsea fish and whales.

[@dododimitrov9657]

@@ekszentrik but the recent data confirmed phosphorus, which is essential building blocks of life.

[@ekszentrik]

@@rocketchicken5421 HAHAHAHA. You know these boorish anti-science types you see in mainstream media? That is you. Radiation does not penetrate past a few meters of water. Honestly it's embarrassing for me to even have to tell you to "go google" this basic science fact. Yes, humans will never walk the bare surface of Europa. But we don't care about that. Well, if you want to be hyper speculative about complex life. Balloon animals on Jupter? Methane based life on Titan? Snore. Pure schlock sci-fi. NOT impossible, but so unlikely it's boring. Enceladus likely has no complex life. It's too young. Just 500 million years. Complex life on Earth popped up after 3 billion years. Ganymede is a lifeless "ice (cream) sandwich". The ground is encased in ice, unlike on Europa.

[@paulspencer5467]

There are also subsurface oceana on ganymede, maybe callisto, triton, enceladus and pluto, and triton is actually a captured object from outside the solar system, so maybe something could have stayed frozen in that ocean to survive the journey across solar systems, only to be reawakened when it got captured in Neptune's gravitational field.

[@ekszentrik]

@@paulspencer5467 Triton is probably the second best chance for complex life, as it's the biggest water-containing object in the Solar System besides the Galiean Moons and Titan. There probably is some internal heating from Neptune. Pluto is slightly smaller, but in mind would still be the third most likely place for complex life. Ganymede almost certainly can't support complex life, because the water mass is heavy enough that the lowest layers are compressed to exotic ice. This means there is no interface between minerals and the water. (Simple life likely has very good chances to arise on Ganymede in volcanic hotspots where there's no ice) Callisto seems to be undifferentiated, i.e. not have an ocean. Titan has the same exotic ice problem, and on the surface I am very optimistic that life can arise, but only simple and I wouldn't bet on it having already happened (remember Titan has only a fifth of the surface area i.e. "event staging ground", and much lower temperatures. So everything happens less often). Enceladus is fine for simple life, but it's a very young moon. Less than 1 billion years old.

[@Zeder95]

If it makes you feel better, if humanity is still around by then we will probably have settled on many exoplanets in other star systems and become a multi-planetary/multi-stellar species. In our own solar system, we will probably also have terraformed and inhabited Mars and Venus. And when the sun expands to its red giant phase, the habitable zone will move to Jupiter and Saturn, which means we can terraform and inhabit the large moons Io, Europa, Ganymede, Callisto and Titan by then. And (this is very hypothethical and speculative) we might have even developed a method to move around the entire earth by then by building some kind of giant rocket engine to push Earth further away from the increasing/expanding sun to keep it in the habitable zone. Since the suns increasing luminority and size happen very slowly over hundreds of millions of years, we would only need to move the Earth very slowly, maybe 1 km per year or even less would be enough to escape the slowly expanding sun. We could also do the same with a terraformed Venus and Mars. We could push them to all become moons of Jupiter, staying in the expanding habitable zone. After the sun becomes a white dwarf we would need to move the earth (and Mars and Venus) inwards again since the habitable zone will be much further inwards. There we will have hundreds of billions of years more.

Nah, Venus will get destroyed in the red giant phase. But the Past and Future of Uranus or Neptune might be more interesting (and don’t you DARE comment any dirty jokes about Uranus.)

[@austinreed5805]

Within the next few millennia, Europa could become a new habitable planet. If humanity gets that far, then the terraforming of Europa is a big possibility.

People from Europa would probably be called Europans.

[@Straya09]

What about the past and future of Ganymede? To me, Ganymede is a much better version of Europa. It has a magnetic field, which could help it retain an atmosphere for billions of years. It also has ice and other stuff found on Europa.

[@skurinski]

its not as good as an option as Europa to find alien life in its oceans

[@scientchahming5]

Let's send robotic submarines into the ocean of Europa! Living things could exist there, akin to the organisms that reside around geothermal vents on Earth.
