Your content is superb, Alex. What I love most is someone who is as passionate about space as I am. I have never supported channels, but I honestly believe you deserve it. 🎉 love from South Africa 🇿🇦
"Can we study extraterrestrial oceans?"
"We have oceans at home."
To be fair we’ve mapped mars better than the oceans
The old "not enough learned about our own homeworld" excuse 😯
We're here, why should we go over there?
I can think of many many reasons.
Doing both is more interesting.
"No no no, you don't understand, that's _why_ we're trying to leave."
and there's the underwater variation of UAPs - ex Navy folks have accounts just like the better known airmen accounts
I'm not saying it's aliens...........................but it's definitely aliens.
Obviously not.
@@dogwalker666 ಠ_ಠ
@@dogwalker666 Obviously.
@@vaenii5056 Lol. Nice fantasy but nope.
@@dogwalker666 It's never aliens.
They're looking for a very VERY special starfish, a rare expensive crab, a long nosed squid, and a small yellow dish sponge.
I got stuck on starfish being a space reference....... Can't tell you how many times I read that 👏🤣
Bikini bottom
They’re getting ready for a mission to Europa!
Uho.... we're not supposed to attempt any landing there! 🤭
I wish
Oh do I hope you're right!
@@JoranaRowan why?
@@alizaidanthamyeez740 2001 Space Odyssey reference.
So we can go into space, but not to the bottom of the ocean.
And nobody questions this…
Yup!
NASA has PLENTY of experience working underwater
I was born to question this stuff.
You don’t understand pressure, do you?
Read up on what cave divers have to do when going down so many feet, how long it takes them to resurface to acclimate their bodies as they can’t just swim directly up. We can’t just freely go down into the ocean and back up with no issues.
You see what happened to the Oceangate stuff with the submersible, right? Pressure caused it to cave in like a squashed can and _pop_ … and they were in something designed to go down so many feet, but you can’t be down there long.
We can’t exactly protect equipment and people going down that far to the very bottom. We’ve only been able to go down so many feet below sea level, but places like the Mariana Trench are nigh impossible for us to freely go down into towards the bottom completely even with proper equipment we have today that allows us to go so many feet down. The pressure there is THAT immense.
We’re able to do it with space due to no gravity, but the gravity here on earth causes the pressure to be much more. It’s basic common sense … and it’s scary how many people watch videos like this and get TikTok tier news fed to them and think they’re being intellectuals while thinking everyone else is dumb despite completely misunderstanding (or intentionally ignoring) basic science. Come on …
This particular question has been answered at least 15 times on youtube alone. 1 google search and you get an answer.
But God forbid you'd actually look something up right
@@JoeyP946 im talking about technology, not funding.
Wow CZcams actually notified me about a video right as it was updated and not 2 days later? Wild.
Ikr
This is for space travel. They're literally a space agency. Lmao
You actually get notifications? Lucky
You must be real naughty ! 😉
Still waiting for my Astrum "Ding"... Found it by accident, also found out that after a update, most of my Notification Bell checks were unchecked 😐 why YT. Why
NASA finally realised that the oceans are just as much an alien world as the countless planets in our heavens...
NASA does what it's allowed to do through funding. They've realized many things for decades. It's the federal government who has to be convinced.
Why call it alien when it's literally from our planet haha
@@johnnymitnick we have only explored 5% of our oceans. That's about as alien as it can be.
Whut? Brother nasa is not founded neither funded to work on ocean "alien life" but can learn a lot on plate tectonics, sediments-just to understand other planets...
Shouldn't NAOA be doing all this instead ?
NASA needs it's budget for "up there".
Never really considered it, but testing in the deep sea could be a good proving ground for Venus missions. Could test some materials at super high pressures
Europa, Enceladus, both are believed to have oceans and NASA has talked about submarine missions for years. Venus will melt any electronic systems we can currently build.
The pressure part is already solved. What is holding us back is the temperature. At surface Venus pressure is "just" the same of 900m depth on Earth. There are several submarines that routinely go there.
@@sysbofh and the acidity.
We are intending to go to Europa, which is an ocean world (or moon if you prefer), makes sense to test things in an ocean.
@@M1ggins It's solved too. Everyday we transport strong acids, this is a known quantity.
What we can't do (yet) is electronics that stand 450C. Even batteries are already solved (take a look at molten batteries). In fact, those batteries would feel right at home.
Okay enough, youve convinced me.
I'll replay subnautica again.
*sighs, unzips subnauctica and below zero files*
😂😂😂😂 fucking love those games
When will people realize..... we are the aliens
That’s what I’m saying. We are proof life is out there. I believe so called aliens are just different breed of human
yea. That's why we share so much DNA and biology with all other living things on this planet. Cause we aliens
Subnautica is a terrifying game about an alien ocean
I love that game 😂 I would not want to meet the creature's in that , for sure .
@@MardyMotherThe reaper Leviathan says hi
Nasa's budget cuts got too low, they are trying to find treasure at this point xD
Shh. As long as we get pretty pictures.
Couldn't be more wrong 😂 our gov prints money out of thin air and spends trillions of unaccounted dollars
@@thecooldude71 NASA spending budget is really sad tbh.
@@thecooldude71 Have you seen how low NASA's budget is? It's like 0.8% of the total US spending
@@thecooldude71yea but none of that is on nasa, They’ve been getting nothing but pay cuts recently.
I was always so confused why there’s so much focus on space when there’s a whole ocean we haven’t explored.
Perhaps preparing for future Europa mission?Gotta test those space-submarines on the harshest earth ocean before they dive into alien ocean.
也许是在为去木卫二的任务做准备？木卫二潜水器肯定得在最严峻的地球海洋里测试后才能去外星海洋里冒险。
Aliens: disappear into the ocean on Navy footage

Thank you Astrum for another top tier quality video. I'd love to see some more content from you based on our oceans and the deep somewhat alien world. You have one if the best narration voices ever. You would not be out of place on the BBC. I love your content you somehow make what is already interesting even more so. I shall support you on patreon as soon as i am able to do so. For now i make sure to press like on every video i watch. Wholeheartedly, thank you Astrum.
this inspired me so much, thank you team Astrum ❤❤
great informative video as always.. Keep it up!
Being interested in animals, the deep ocean and space.. my mind sometimes goes down the rabbithole into what else biology and evolution could come up with.
Ironically humans seem to be the only animals so interested in other animals 😂 like I don’t see cats studying mice and dogs 😂😂 that just hit me
@@dreammaker9642 haha yeah it's quite remarkable and funny if you really think about it. We're the only one going "OH!!! Look at that random animal doing something relatable or totally weird" 🤭
IDK who first said it but I remember some quote about us being the universe, staring back at itself. I quite like that perspective ^^
@@CenarosNL I do like that perspective 😂 although sometimes the way my cat would look at me he was definitely thinking “what is this chimp up to now?” 😂 lmao as I’m writing this my dog also gave me that look on queue 😂
Thank you Alex and your team. I enjoy your well-expressed enthusiasm about exploration of these challenging places...
Excellent episode! Thank you for all the hard work you do!
As well as being fascinating and informative, your content is so uplifting too.

Really loved this close to home posting - thanks Alex
Great video as always. Thanks Alex!
Marine biologists who I've seen asked about the whole "never having mapped the ocean floor", the response was generally, "We don't need to, we know what's down there already."
What is it? Is it sand? It gotta be sand right?
Wouldn’t the same argument apply for mapping land?
@@SerfinBird sand and those covid face masks
More accurately you don’t want to know what’s down there. However the “90% of the ocean is unexplored” part isn’t accurate cause 90% is actually just plain open ocean of nothing. Life is a lot more localised than you think.
@@dreammaker9642now you really believe 90% is just “plain” ocean. I got a few bridges for you, only $20 mil each
I wish I could live forever to experience these events when it happens. =/
Oh Don't worry, we get reincarnated. So you'll see it, you just wont remember wanting to.
Noooooo you don't lol Just be glad you live now when you do, it might seem rough but that's because you got nothing to compare it to. Be happy.
@@genericalfishtycoon3853 Daddy Elon gonna give us Robot Bodies and we're gonna out-live the sun!!.. (or maybe a Week cause Daddy gave us a Temu battery pack)
@@rogerwilco1777 lol Temu battery packs, they'd probably just explode. 😅
The ocean is really just the first layer of the atmosphere.
Wonderful video ! Thank you for sharing . Happy Friday to you !
Awesome videos as always say man
Fascinating! Excellent work, thanks 👍
yess two of my favourite things, space and the deep ocean
Well done. Thank you!
Just stay clear of the Despair Squid. It can prove problematic.
Damn, bloke. I watched that episode last night. 😂
Love a good RD reference 😅
Thanks, Alex! 🪸
On a side note. CZcams should be sued with the amount of ads they now show while watching. 😂
VPN to Albania, no more ads
CZcams premium will solve that.
This is really exciting stuff!
Got this 7days late. Glad it showed up great video.
Awesome episode thx 👌
Alex, this episode was fantastic!
Thanks!
Excellent video!! . Watched this movie Europa Report last night and woke up and this was the first thing that popped up. Gotta love that Algorithm!! I didn't know NASA had a base submerged beneath the ocean.
It was great as always, perfect 👍
Why would a dominant species hide away in the depths and darkness of the Oceans when they could live on the Continents?
I wonder if we could seed life on Europa or Encealedus? Would it even be right to do that? I guess there's a super low chance that it could even effect life on Earth at all, so philisophically it's nuetral at worst and potentially godlike at best.
Essentially, my idea is to transport plankton to one of these worlds (probably encealadus.) On Encealadus you have the outgassing effect that theoretically opens holes in the ice crust, a phenomenon we haven't observed on a large scale from Europa. If there are holes that periodically open then theoretically light from the sun can touch the water inside the crust of Encealadus. If that's the case then maybe it's possible to get phytoplankton to survive there and conduct photosynthises : O
Yeeees underwater theme!!
As long as they leave the moon alone, they can go long and deep to the bottom of the ocean since we can't take care of the land earth.
Bots jumped on this FAST
I hope we discover more how our oceans work, looks and creatures that life there.
But I can understand why "exploring" the surfaces of other planets is easier, since nothing is covering the surface, so easier to see stuff, compared to the ocean
UFO's are sometimes spotted entering the water, makes sense to map the bottom. Designing drones to explore caves and alien oceans also makes sense, there may be oceans on Europa, it would be logical to fix design issues on Earth first.
I would be okay with NASA focusing on oceanic exploration while balancing maintenance on current orbital equipment. We are not realistically close to colonizing Mars, let alone interplanetary travel. Let’s focus on oceanic explorations and deep-sea colonization. That will also help prepare for future missions to Mars or other colonization missions. That being said I wish there was more of a push for colonizing Europa INSTEAD of Mars. Love these videos
Fantastic video. Thanks Alex & team!
We should definitely focus on the ocean to eventually master pressure builds. Just my thought
I've always said ....if we cant conquer the ocean, we should not be going into space. Finally NASA.
There are more life forms below sea level than what the entirety of mankind has discovered topside over thousands of years. That's just a fact.
🐲✨🐲✨🐲✨
"Just because you do not see something doesn't mean it isn't there." --Starshaa (DD1)
🐲✨🐲✨🐲✨
about damn time!
It's plausible that thousands of years ago, Earth was an unidentified alien planet, meaning the likelihood of UFOs crashing or leaving remnants is very high, particularly in the ocean due to its geographical changes over time. Interesting yet very terrifying
I think itd be eerie to finally go into Europa's ocean
Imagine that feeling of 'yeah, this looks like Earth's oceans but... why isnt there anything here?'
Really hoping there is life there, but I'm not too confident
Thanks for another great video. I personally think that we may even stand a chance to find life (single cell and other, very small lifeforms) a few metres down in the ice cap. It happens on earth and once you're safe from Jupiter's magnetic field radiation and find liquid water where the ice cracks and moves...; well one can dream. Also the underside of our terrestrial polar ice caps are teeming with life so this might be true on other similar biomes.
Possibly under the much more Earthlike icecaps on Mars.
So apparantly aliens come from the ocean now. Maybe that's why they're there lol.
Reminds me of my favorite story arc in the manga and anime Space Brothers.
Question: If we've not mapped but just over 25% of our ocean how do they know that the maryenna trench is the deepest part of the ocean ?
I share the same opinion as others that we should research our own planet before going elsewhere and the ocean is something that always bugged me.
2030: NASA discovers life in Europa
Discovered life: yeti crabs 🦀 lots of yeti crabs
I saw the "We should not be here", but I'm reminded of the similarities between other worlds in our solar system and oceanic depths. Like what is suspected to lie at depth in Uranus or Neptune. Or the more hellish versions in Jupiter, probably in Saturn, and possibly on Venus (if dense CO2 can become liquid-like. ... Until we have standardized or bespoke vehicles designed for that kind of on-/in-planet travel, NASA is probably a best-choice for initial investigating.
Above the sky beyond our firmament are oceans above... Hope that makes sense
What's down there is all the socks that ever disappeared in the dryer.
...and plastic.. lots of plastic
@@rogerwilco1777Bonesss 😸
I couldn't agree more, NASA SHOULDN'T be exploring the oceans, or doing a lot of the things they do. This is EXACTLY why we're still stuck here on Earth, because NASA is like a child with ADHD "oh! what's this? OH! What's that?!?" They can't focus on anything more than a few years which is why they end up going nowhere.
You realise a lot of the technology you have is thanks to them 😂it does take some big brain activity but essentially to solve some problems you may have with space exploration you end up making discoveries that have other applications that are very useful. For example not sure if it was NASA particularly but some very clever people learned by studying the cosmos that when hit with certain radiation you can differentiate very accurately different matter making observing the universe and things like nebulas much easier.
With that discovery some clever doctor came along and realise hold on what if I could put a human body in there and similar to an X-ray which were also discovered through space exploration btw, well you could essentially snap a picture of what’s beneath the skin and differentiate between muscle bones and other tissue and more importantly you can see irregular masses aka cancer and thus was born the Nuclear Magnetic Radiation Imaging (NMRI) commonly known as MRI because regular joes get scared when they hear the word nuclear. So thanks to a dude who just happened to want to know more about what’s up there millions of people live cancer free because they got diagnosed in time thanks to MRI and Petscans so you’re welcome buddy
We do have a planet where the atmospheric pressure is so great that crushes our probes. Seems like the ocean would be a good start
Answering the title cold... Learning how to conduct missions in extreme pressure environments. Venus is pretty hostile... Jovian and Saturnian moons have oceans...
Got a handy ocean or two here to get some practice in before trying anything tough....
Life is EVERYWHERE , you just need to look harder . deeper further .
Have you heard they got Voyager 1 back running properly again by shutting the broken part down and moving its job to other parts of the craft?
I thought they were still working on it but knew what they had to do. Good if they've got it working.
@@rais1953 as far as I'm aware they're still doing tests to make sure its 100% working as intended, I haven't heard much since but I hope it gets back to giving useful data again, fingers crossed
I really really REALLY hope this is for Europa. I have so many probably naive hopes for what we'll find there
Sorta off subject, but Gordon Cooper took Hi-Def photos from space and later with a Treasure hunter friend they looked up were he was able to pinpoint Hundred years old shipwrecks ! Nice to have that ability! The only one with it !
I think using the ocean as a testing area for NASA is actually a really good idea. Even though things in space don’t require the ability to survive extreme pressure. There are things on other planets that we hope to explore at some point that likely do have extreme pressure And well there’s only so much you can do in a laboratory.
Not only that, but I actually like this idea. Contrary to popular belief, we actually know less about our own oceans than we do about the surface of Mars.
Over 2/3 if I recall correctly of the planets surface is covered in water and yet again we know less about it than we do about a planet a couple billion miles away.
Looking for the aliens from The Abyss.
my understanding is that water across the universe is very similar,with a few variations with silicon and other substances that can create life its astonishing how silicon is very similar to our human life forms
I don't know if it is a good or bad thing, that the most unrealistic thing in the Europa mission (that i can imagine) is the 200 Kilometer Kable that the lander would have to carry
Speaking of our oceans... it's high time global efforts focused on cleaning up plastic in our oceans (among other pollutants). I've heard that ocean going vessels already exist that collect plastic (one of them uses plastic as its fuel). Plastic is slightly carcinogenic, an endocrine disruptor and microplastics have been found in autopsies of animals and humans.
I knew about NASA going to the waters but I mostly care about space exploration. Is NASA going to make Minecraft underground Bunker?
Really important topic ...
they wont tell you but we allready have bases on mars and the moon because we work with other species on mars and the moon
For us to have a better understanding of possible alien biology, we should start with early bacterial life on earth and its evolutionary path to complex organisms dwelling in extreme environments(anaerobic, high and low pressure/heat/cold environments) in combination with the use of AI simulation. Because if complex alien organisms exist, their evolutionary roots would have been similar until a divergence in the path occurs based on environmental conditions.
Hopefully they are quietly exploring alternative theories about planetary formation. If planets formed like geodes from electrical forces forcing disparate matter into spherical shells, then it's entirely possible that they are considering that the core of the planet might be liquid water, not molten iron.
The notion that a planet *needs* a spinning iron core to create an electromagnetic field is no longer needed, since it has been proven that the Earth receives quite a large electrical load from the Sun 24/7/365, so there's the electromagnetic field spinning the dielectric lithosphere of Earth and all the rest of the planets.
Lastly, the recent discovery of the 'vast underground ocean' that they have deduced exists should really put the cherry on top of the argument. The water is salty and conductive, allowing for the constant heating via electrical resistivity, the perpetual magnetic field that can flip as does the Sun's (both are electrodynamic vs electrostatic events) and needs no other ferrous assistance to achieve.
In truth, with all of the latest discoveries, combined with a 1st-year course in Electronics, one can easily see the plausibility of the argument. Sadly, we have no technology to dig through the solid-plasma rock that defeats our current drilling technology, wherein the rock's displays a level of plasticity that is insane for 'solid' rock.
If only the Sciences would get back to looking for new ways to falsify the current paradigms, like they are supposed to per the definition of 'empirical science' and stop with the "We know for a fact..." statements about things that we cannot yet disprove.
My best guess is they are trying to simulate something like diving in Titan. Or at least some moon with water. They will need submersible tech for their distant plans.
If they're using a heat source to burrow down through the ice, how are they going to stop the surface hole, up near the lander deploying the heat source, from freezing over?
Excellent
Composite substances need to be incorporated alongside 3d printing to revolutionize the industry of underwater expansion in exploration and understanding. Is it truly out of reach to ditch the small crawl spaces and expand the working quarters and passage ways? If you cut down on glass usage(minimal surface area made with glass) and instead incorporate drone like crabs to maintain cameras and sensor functions for perceptive capacity.

First thing popped into my mind when I saw the thumbnail was aliens
The earth is 79% ocean. If aliens were to land on earth (crash even), chances are they landed in the ocean. Another awesome thing about the depths of the oceans is that there are practically no live humans there.
Great video...👍
@ 3:40
I always knew SeaLab was real
I was always wondering why they didn't study our own depths, instead going up to space. But they are studying our own planet, and it makes my day.
NASA's main job is studying things that affect aeronautics, and space travel(including astronaut health).
It wasn't until the late 1960's that science started to understand just how much the ocean controlled the atmosphere. So they started studying the ocean.
NASA casually looking for aliens at the bottom of the ocean…
I can’t wait for the day we get footage from the Europian oceans
Me: Can we visit alien life in Europa Oceans?
Mum: We already have alien life at home
The alien life at home:
I just realized the bottom of the sea gives me greater vertigo than thinking about being in space.
7:51 How do we know there isn't just straight up life on the surface?
Can you say, "About damned time!"? I was talking about this disparity back in the 70s in high school. Why we spend so much money exploring other planets/moons vs exploring our own backyard has always confounded me.
Cause zero pressure is easier to deal with than extreme pressure. In outer space you don’t have to worry that much about your several million $ craft imploding because of the slightest dent.
