And if you were born 200 years later you would regret not being able to colonize the Andromeda galaxy. Its all relative mate, be thankful that atleast you get to see Humanity be able to explore and soon colonize multiple planets. You may not see a completely terraformed Mars, Venus or Europa but you will see the beginning stages of colonisation/mining outposts on other planets/moons/asteroids.

Ice plumes come up to the surface from even further down, that would mean there is a great chance that whatever may be in the water will get erupted onto the surface. Granted it will be dead, but it should leave something to be studied.

@dsbs96
7 жыл бұрын
You don't need to go that deep to find what it's needed. 10 cm under the icy surface should, theoretically, be enough to find cells if they were forming in the planet. The icy surface insulate the inside well enough to keep everything inside (yeah, even 10 cm) at a general constant temperature. Now, if you want to get to the ocean under it... you would need a big drill, and that's not happening unless they find a good reason to do it.

As long as you're not blinded by ignorance and won't accept reasonable arguments or proof conflicting your own ideas. +daniel leca Yeah, I know. It's basically impossible to get down there, but then I really have my doubts that a sample from 10cm deep is able to exclude the possibility of life on Europa if it's not found there. +Dani Azakura If liquid water is such a big deal for finding life, then why would a sample 10 cm down in an icecrust be sufficient? I'm not expecting there to be like fish swimming in Europa's ocean, but wouldn't finding life in the actual water be far more likely than finding it encased in ice? Again, I know we can't get there with current tech, but still.

How is that deep enough to find life? That's just old ice. Gonna need to drill deep.
I really hope the lander makes it. It will be amazing to see a "Jupiter rise" on Europa.
It is great to see your excitement.
You all do a outstanding job Thank you!!!
Finally, Europa getting some love. More interesting than most stuff NASA does tbh.
Proximus is a red dwarf, so that means that b is really close to its star right? Cause then we know the planet will prob be in a tidally locked orbit. Is it possible that around the line between the dark and bright side (hot and cold) there is a spot where there will be just the right temperature for water to exist. And that this spot (little more towards the dark side) will be safe from radiation because of the rock between the spot and the sun. Or ice on the dark side where the molecules didn't make it in to the atmosphere (like on the moon in some craters where there is never sunlight). And because of the activity in the planet (because it is so close to the sun) there will be warmth from beneath so that water could exist under the ice on the dark side. And so, potentially life. Microbial life ofc. Just a question!
I love you passion and she seem very enthusiastic I enjoy watching her videos 🙂❤️❤️❤️❤️❤️
"All of these worlds are yours except Europa; attempting no landing there....."
This stuff makes me so giddy!!! So cool!
Let's take a trip to a moon baby. Let's take a trip to the stars, far away.
This was one of my favorite episodes for sure. Thx! ^_^

Everyone go and watch "Europa Report" the movie!
this is amazing! what a time to be alive!
I love how positive she is
There are no words to describe how much I love this host. She's adorable and you can tell she really loves what she's talking about. Europa's eels, here we come!
I'm not holding my breath, but if we do find life under Eruopa's surface I will be ecstatic!
I know a lot of commenters are saying "only 10cm?", well there are many reasons for this. For one, they can't launch off a big drill, not for a first attempt. It will be bulky and will cost a hell of a lot more on an already tight budget, and you don't want to risk a malfunction or something unexpected on extremely expensive equipment, not on this first run. The drill needs to be small so it can get small enough samples into the microscope. Chances are they will have a backup drill just in case the other malfunctions, and they need to be small and well shielded to protect against Jupiters nasty radiation. Also, I'm very sure they will pick a landing site on one of the "tiger stripes", this is where the warmer water is welling up from vents due to tidal forces squeezing and pulling Europa by Jupiters gravity. The warm water then freezes near the surface thus trapping whatever could be in the water at the time. This is an extremely exciting mission, even if we don't find life, we will find out the composition of Europa and other exciting sciency stuff.
I imagine somewhere in the Universe many Creatures/Civilisations have Evolved or Adapted to thrive in high Radiation Environments. Darwin's evolution applies to a Universe folks

For those who think 10cm is too short, I honestly don't think the probe could bring equipment light enough or small enough to drill deeper... it would be a bit harder
SUPER EXCITED ABOUT THIS MISSION
We should commission the commercial council of Magrathea just to build us a planet, I hear they do good work.
Would it be possible to launch a submersible into Europas ocean and explore things, like vents?
Dayyum, I've never been this early for a SciShow video
We all know even if they find life, we would never hear about it. The only reason they look for ancient life is in the hopes that it left oil deposits.
It will be the greatest mission so far!
Interesting, very interesting.
She doesn't blink! At all!

David Durant I was looking for this in the comments.... and I wasn't disappointed. Go have a cookie. You deserve it!
proxima B sounds like a planet from a star trek episode. The Next generation I think covered it. how the planet was dying and its people only had one opportunity to get their legacy off of the planet. and picard ends up with their memories and ways being imprinted on him.
"only 4 light years away" hahaha Have thee no understanding of a light year?
I bet Europa is really a frozen Cthulhu and the vibration is its snoring
dump the entire f35 budget on this, we can launch both the europa drill and the titan lake probe by next month(at the earliest) I joke you not
Yeah!! JAZZ HANDS!! my fav!! lol always I mean always super excited and enthusiastic!!
0:20 easy tiger. it's actually hotly debated exactly how much water is on Europa, some scientists think it's 40km deep, other say 60 and other say it could be as much as 100km deep, so don't just flat out say it has exactly 3 times as much water as Earth.
I'll be at least in my 70s' before a probe lands on Europa. I hope I'll be in good enough health to appreciate the moment.
I would like a video on how we know the universe is expanding. I have always wondered that and never found an answer I have found that was very expansive
We also know that there are life able to resist X-rays, you know, fungus.
Even if Proxima B isn't habitable I'd still wanna xhech it out.
3:37 She says this like we can even hope to get to another star in this century, nay, millenium.
thank you for space news
Thanks Caitlin!

Bad news about Proxima b, but I still have my hopes up. Other recent research suggested that Proxima b could be an ocean planet. Until we get there,we can't really be a 100% sure!

Now, even putting that much drilling equipment on a Europa lander is quite a lot to accomplish.
Elite Dangerous has a planet around Proxima called Eden and it mentions the intense radiation rendering it uninhabitable
How do scientists come to the conclusions about the makeup of the inside of planets when we can only see the outside from a few light years away.
I thought the video was going to talk about an actual landing; I can wait though :P
oooh, interesting. I didn't know that Jupiter is so radioactive. But since there's fungus inside the Chernobyl reactor, I don't think alien life would have as many problems with radiation as we do. On a side note, I wished there was a 0.75 speed option.
Ok, so here's my main concern about Europa. Jupiter puts out massive amounts of radiation and if our instruments which are made out of non-organic materials can only last 20 days or so, what in the world makes people so excited about potentially living there in the far future? Yes maybe we would find some form of organic lifeform(s) in which has the potential to be interesting, however you still never will get across the fact that we could never live there combining the factors of radiation, with massive tidal effects due to the host planet the moon revolves around. i would love to see a sci-show episode dedicated to how we as humans could overcome these factors as well as the not mentioned until now the fact that jupiter saves our earth from the asteroid belt and how factors such as that could also effect Europa, and if such other data is known and how that could also affect future colonies or exploration missions.
maybe it will bring some europa-pean lobster to grill up. if you get this reference, you are a winner at life
I was expecting a bit more from the lander tbh. Thinking back I thought a bit too much. A lander that had a drone that would melt its way into the liquid oceans and automatically navigate it taking samples and searching for underground structures.
sayyy whhaaaat! my genuine reaction
I love a good landing, it beats the tar out of a bad one.
still wanna go to proxima B. Exploring other solar systems would be cool
I don't know what sort of conspiracy theories will occur once life is discovered in europa.
Our only remaining hope is *Warp Drive*
But if you took five random samples of ice from the middle of Antarctica, would you be guaranteed to find life?... They could miss it entirely.
45 fly-bys? Is it going to orbit Jupiter?
aquaman lives on europa....you do not want to mess with aquaman.
I think a lander with sonar would be useful on Europa.
Meanwhile, our president is going, "Europa? Have I ever nailed her, I can't remember ... "
Argh, all the presumption! Someone modelled what the environment might be like on Proxima B's planet, so we conclude there is no chance of life. Once we assumed there was little life in the deep oceans... then we discovered hydrothermal vents.
If you set the playback speed of this video to X75 per cent you can comfortably follow what's she's saying. (Incidentally I wouldn't want to miss this sort of science report. It's great, thank you).
Last time i was this early Capitao had grenades #SiegePlayersKnow
Just read the book "Armada" and this title scared me
Yeah, nobody with a little knowledge of the nature of red dwarf stars was holding out much hope for life there. The zone is so close and the stars are so inconstant. Not that we know how long it would take for life to develop anywhere since we haven't more than the foggiest notion of how it could develop. We know that life exists on earth, and we know a lot about the makeup and function of living cells, but nobody has come up with a plausible scientific scenario for how it came to exist.
Uh, hon? Less crack, more decaf!
oh Schmeg! Red Dwarfs. lol
