My boy and I love watching your videos at bedtime, a father - son tradition. Your somniloquent voice makes him sleepy. :) Thanks for the great vids and memories.
I was also shown the wonders of the universe from a young age and it's stuck with me ever since! Great to hear it's being passed on to the next generation!
points for the use of the word "somniloquent" although I'm not sure that saying the narrator is "muttering in his sleep" is to be taken as a compliment or a backhanded insult? LOL
Don’t touch him
What a great idea. Cant wait to show my oldest son these videos
Bless you.
As a father myself of boys (now grown up), that sounds a beautiful bedtime tradition. I'm sure he'll remember it always.
One of the things I love about your narrating is I can tell you're smiling!
i can smell him smile
@@zaplyte6564 I can feel it
mitch i
I can hear him smile
Truest words ever!
I think Ceres gets glanced over by too many people tbh. It's literally a dwarf planet in our backyard in the middle of the asteroid belt. It may not have cool colors or features, but it's still got that inner watery materials to warrant some sort of surface and crust exploration. Anybody else think it's kinda underrated?
You can't be cereous.
I agree Ceres deserves more attention and exploration. I must admit I was a bit disappointed though when Dawn arrived as I had spent my life thinking Ceres would be a much more dynamic world than it is. Especially after Pluto was so amazing.
Yeah I never heard about it until today & wonder how long people have known about it?
Bo's is underrated
Ceres and the asteroid belt in general appear to be a low priority in exploration.
As ion propulsion is improved we will see more missions to the asteroid belt and beyond maybe human missions as well.
Imagine a crewed ship reaching Mars in less then half the time it takes now for a vehicle to reach that area of space.
And probes that could tour the asteroid belt at leisure exploring the various points of interest.
"There are no laws in Ceres, just cops" -Detective Miller
Is that from the Expanse books?
“Doors and corners are we’re they getchya”
I came here specifically for an Expanse reference, and there it was--BAM--right out the chute.
What version of Miller do you mean, with hat or without ?

If something appears uninteresting and boring, It just means you aren't looking close enough.
exactly we like to oversimplify and approximate our views with categories, heuristics and preconceived biases its easy to see what you expect and move on without really scratching the surface
Agreed!
And if it really is boring, then that's because you picked something boring to examine, in which case you should pick something else.
This conversation is boring.
@@MelindaGreen life and the universe are way too complex to ever be boring
I grew up with the nine familiar planets (as they were then), and it's really fascinating to hear how much OTHER stuff there is in and around the solar system.
I know right!
To be fair, most of these dwarf planets have been little more than points of light in a telescope's lens or pixelated spots in digital imagery, if they were discovered at all. We probably categorized Pluto as a planet because we didn't know that point of light was actually two object, Pluto and Charon, in a binary dwarf planet system until 1978. Using the light from both bodies to calculate its mass, we probably assumed Pluto was more massive than it actually was. We also didn't confirm discovery of the Kuiper Belt and all it's Pluto-sized objects until 1992, making Pluto much less special (planet worthy).
I'm very excited for the Lucy mission, which just launched a week ago. It'll fly by multiple asteroids in Jupiter's orbit over a 12-year period. Sadly, we have to wait over 5 years the first images.
There is even life out there
I Ceresly like this channel. Thanks Alex!
Hello funny I'm Dad

STaSHZILLA you have good content
I see what you did there.....
@@michaelcoulter1114 Ah, it Dawned on you :)
I really like this channel I'm a truck driver and I love listening to your voice driving
As long as they don't find the proto-molecule, I'm ok.
Some might say..... At least no humans there
what kind of proto-molecule?
@Pintkonan watch The Expanse, on Amazon Prime, and find out :)
The stargates would be kind of cool though.
It’s late . “ They “ found it and are taking advantage of everything to their own benefit .
I must say Alex, I absolutely love your channel. You have reignited a love for astronomy in me and I am very grateful.

Very much appreciate these videos. You explain things well. And as I have said before, you seem to present these in such a way that keeps my interest. I have enjoyed listening watching and plan on supporting you as much as I can, when I have opportunity.
Big thanks again, and please don’t stop making these. I’m sure it’s difficult sometimes researching and production. And hope I can help in anyway. I’ve been watching every single morning now for almost a year. Really gets my mind moving. Really, who needs coffee?
Can’t wait for next episode.

Very informative video, thank you! I always found Ceres somewhat mysterious, hiding in the asteroid belt between planets, an unborn world, lurking in the shadows.
Ceres looks like someone took Mercury, and decided to squish it into a compact, tiny potato, while freezing it, then boiling the outside.
Space salt on your potatoes? 🍠
Why would you need to boil mercury, it is already the 2nd hottest planet 😂
Now ! I'm hungry !
What a bizarre, yet somehow completely accurate description
and replacing iron with water lol
Even though it's been almost 30 years since the Hubble was deployed, it feels like yesterday to me. I remember being amazed at the resolution of the images it captured. Now look!
We are living in very exciting times!
I will think of you when the James Webb deploys.
@@jdsd744 The latest launch date is now 3/30/21. Very much looking forward to it! (I just hope I'm not disappointed again...)
Wish you would have provided more information on the scale, especially considering you mention scale and the difficulty of understanding it int the photos you showed.
Yeah, like an Empire State building nestled into one of the craters, or next to one of the mountains... I agree...
that is a good critique, he should consider that in future videos
There was one reference to scale in the cone shaped mountain called Ahuna Mons which was though to be a cryovolcano. The given heght was 5 km or 3.1 miles.
@@Quickened1 Yes that or a stack of elephants or school buses.
U did show a city in comparison in one video. That would be great to see. Thank you again. Love your videos. Watch them before going to sleep, so I can dream about it. Cheers from Brazil
Love your videos Alex. Your channel is the only one I know of that talks about the finer insights of our space exploration....
This channel's narration is goldilocks. Not too fast, not too slow, juuuust right.
I really look forward to astrum. Every new video is a wonderful fun adventure so well done and so well put together
Ahuna Mons looks like a giant alien child took a sand shovel, scooped it out of the crater next to it, and plopped it over.
exactly what i was thinking
That is the array antenna. We took the bait.
@@alectraproject its actually ancient forerunner ruins that hold the key to all the halo installations locations
Thank you. I'm very interested in this stuff but I didn't know about this mission. So happy that, thanks to your channel, not only do I get to learn about the mission but I get to see the amazing results!
Great video! I remember Ceres before we had HST images! It was such a mystery! Astronomers believed that it was probably a giant metallic/rocky asteroid. Then there was speculation that maybe it was more icy, since it nears the Frost Line. Later, Ceres was believed to maybe have a subterranean ocean. It seems to be in the middle-not too rocky/metallic-not too icy/volatile. This is a very interesting object! The neutron and gamma-ray spectrometer does a great job at finding chemical composition signatures! The images from _Dawn_ are amazing! What a world! This would be so cool to visit! Ceres could maybe serve as a "halfway point" and "supply station" to the outer planets! I love these! Thank you, Astrum! 👍
Ceres has huge potential value as a waystation and refueling source for missions into the outer solar system. Water to make fuel, combined with very low gravity, means that it would be very simple to launch refueling drones from the surface of Ceres to intercept outbound interplanetary missions, refuel (and rehydrate if manned) them, and then return because the low gravity makes landing again easier as well. It's much more valuable real estate than one might think.
Thank you for making this video Astrum, i was clueless about this mission.
Brilliant video, thank you. A size comparison of Ceres and it's features would be enormously helpful.
This was a really good one. I knew nothing of Ceres or the ION drive engine that took us there. Thanks for bring these to TH-cam!
gahd damn I love your work! so nice seeing things i've never seen and learning about things I'm interested in and love so much. I'll never forget watching the huygens probe land, and I'll never forget your titan video showing me things I'd never seen about my favorite subject in space. Thank you!
Another fantastic video. The visuals are awe inspiring, and the music is so appropriate, mysterious, subtle, just right. It's an honor to see my name in the credits. I'm so pleased to be able to help make this magic happen, along with all the other supporters.
This is exactly why I watch your channel. Just learned something new today . I never knew this planet existed . Thanks Alex
Thanks for the video. I was wondering about that planet if it is different from any other moon. You are the best Alex.
Awesome Update, looking forward to more, soon.
Thanks again.
Love the high quality of information from this chanel. Well done!
Sad ending to an incredible mission! Thank you for the update! 👍👍
Interesting topic presented professionally. Thanks for eschewing the silliness that accompanies too many science and tech videos.
A seriously good series of images on Ceres. Truly important knowledge of our lesser recognized orphan dwarven neighbour to trigger our endorphins.
"Water is present in large quantities, making up perhaps 50% of its total volume."
The Expanse - "In the Belt, air and water are more precious than gold."
For real though its actually super cool how our understanding of the universe is advancing so fast that pretty soon James A. Corey is going to be as scientifically outdated as Bradbury or Asimov.
Water, H2O, is likely the most abundant molecule in the universe after molecular hydrogen, H2. There’s likely loads of ammonia, NH3, and methane, CH4, in the outer solar system. Hydrogen, oxygen, carbon and nitrogen. We just need to bring along some trace elements and we can pretty much live off the land anywhere in our solar system and very likely any other star system.
@@CarFreeSegnitz I don't think we need to supply the elements as much as we need to supply the energy, which is much harder.
Keep a hundred million people hydrated with ocean water. Abundance is not usefulness.
@@CalPhotoGuy desalinate the abundance and there you go, useful drinking water 🚰
Keep the vids up love them. The size of this earth i guarantee there life on other planets. Just subscribe so plz keep up the vids
A+ video...loved it! I sure hope others catch your quip on no VPN service on Ceres at the end of this video...that was hilarious! 😄
One other plus for this video the music Doesn’t drown out the narration ! 👍👏🏼👏🏼👏🏼👍👍👍👍
Amazing video, Yours voice is so relaxing. Keep going it's great content.
Fantastic view of Ceres. Great detail of surface features.
You Are Awesome! Thank you so much. Your space vids make me happy. Please keep doing this.
I have been in love with The Expanse and the use of real planetary bodies like Eros and Ceres made this a particularly interesting video... I think it interesting we're now toying with ion engines that could send a crew capsule to Mars (NASA called it the X-3 or something) and it's just such an exciting time to be alive!
When people first heard Pluto wasn't a full planet anymore, they got quite upset - but here's the thing, there are so many other objects in the solar system that we have hardly remembered the names for (I mean, do we have acronyms for all the planets and dwarf planets?) Just feels like when people say that, they are arguing with scientists that are trying to make sese of the solar system... Not unlike feathered dinosaurs... I like the new stuff, onward and upward!
Some actual scientists also believe that Pluto should be a planet. One in particular, Alan Stern, says that Pluto and Ceres, and many more should all be considered planets.
Them “bright spots” are the docking lights of Ceres Setashion.
"Them"?
Setashion?
Ion-Thruster: I love it!
Thanks. Enjoyed the video and the narration is just right.
Said before, say again! You have a splendid voice and accent. Your measured speech adds dignity to weighty topics, and others also have pointed out the frequent 'twinkle in your voice'.
Your channel is pure gold. Thank you for the amazing content!
such a brilliant channel :) thank you for all your hard work and brilliant videos :)
As a Mars researcher stated when asked about the possibility of life there, during the conference held to announce the discovery of water on the Red Planet, every place where water was found on Earth, life was found, too. There's much more to Ceres than we are led to think.
¡Excellent video! I didn't know about the salt trails 👍
...left in a stable orbit around Ceres... That's perfect.
Beautiful and informative, thank you!
😘
Great video. Dexter would agree: Ah, what a fine day for science!
Great video Astrum, keep on! 👏👏
I wonder if the rocks that fell off of the cliffs made a noise? That was cool seeing the little craters it left on the hill bouncing down.
"although I'm British, I spend most of my time in Switzerland"
Finally! Ever since I discovered your channel I've been trying to wrap my head around your accent. it doesn't quite jive with your clearly British name.
His accent caught my attention as well. I think it might be Southern Welsh but I'm not an expert
I think aussie or south African?
Definitely not Texan!
Rade-Blunner
He’s Indian
@@SM-A405FN Certainly not aussie
I felt a thrill when the lights shone so bright on Ceres. I mean, I know that it's all easy to explain through science, but wouldn't it be something to discover alien creatures? That would put our entire existence into a whole new perspective.
There are 90 million species of animal and plants on this planet and jinns and angels which we cant see. Even people who died, their souls are somewhere in universe or in heavens. i dont know why people are so curious about aliens only. we are not alone anyway.
@@ali-k643 mostly the question of whether or not we're alone speaks for our planet as a whole - like is there inhabitance on another planet
There very large chance of life actually being in our solar system, microbial life for sure but intelligent alien life might be quite rare in our galaxy but considering how many planets and stars there is in our galaxy alone it is ignorant and mental to assume there is not intelligent life in fact I venture there is quite a lot of it.
@Siliance Gaming we might or we might not be! We'll never know! This universe is vast. The distances are so huge, we'll never know of their existence
@@ali-k643 Can we please stick to science when talking about science? Thank you.
Bro your narration is calm that makes your content relaxing and interesting at same time
Thanks always love your shows.
Dawn has got to be one of the most revolutionary spacecrafts ever built. It can actually drastically change where it wants to go without huge consequences.
And a perfect video for Sunday morning with my coffee ☕ 👍🌴
I have a question, do you think using an ion engine and our moon and other planets would make it be able to get to a destination faster? Or did they do that already with this engine. Thanks and I hope to hear from you.
great vid! not my favorite vid on youtube, though. My favorite of all time on TH-cam is your long composite video on Opportunity. I plan on treating it to myself once a year or so. Ceres looks like an ideal place to have a base for research and exploitation of the asteroids.
Perfect video for a Sunday evening!
I didn't know you lived in switzerland, haha! Much love and appreciation from-you guessed it-switzerland!
Love your work...
Extremely interesting, and could ion propulsion be used here on planet to reduce need for fossil fuel?
Fascinating! What powers the cryo-volcanoes? Is there a sufficient heat differential between the "muddy mantle", the "hydrated core of rock" and the surface? But what makes the mantle "muddy", since there is no nearby planet/moon gravitational stretching - radioactive
sources?
Another great informative piece of content and thanks for the vpn offer
Everyone!!! Please look at the new photos they released there’s some weird stuff on that dwarf planet
As a fellow Scot, Alex, I would love to hear you own your country and say you're a Scot vs 'British'. 😉
Switzerland? Lucky you. I'm in Australia. 😊
Love your work, pal. 🤩
The space craft is propelled by ion engines that use Xenon gas as the monopropellant. The force this engine generates is the equivalent of the weight of a single sheet of typing paper
With every probe are surprises found. What a spectacular universe!
very good videos! Keep it up!
Great video! Just found your channel and subscribed.
Wonderful videos! As a recent subscriber, I was wondering if anyone knows if there is a video on the channel where they talk about Scholz's star? Can't find one...
Great flic! Thank you!
What is truly mind boggling is the force of a typical ion thruster is about the weight of a quarter on your hand but that thrust in vacuum of space can alter velocity 11km/s?? Mind blowing...
good video, Ceres is a moon like ours, if a larger rock gets hit directly by a smaller very hot rock and was eventually stopped this could still take an extremely long time to cool down even longer without water possibly knocking the larger rock off course or not an atmosphere would be needed creating friction through rotations
Interesting video on the world, Ceres !!
Great material! Btw, "rocks" are not only the ones in the meaning used here, that is, nominally anhydrous (alumino)silicate rocks (which are usually peridotite-like). Clays - hydrated aluminosilicate minerals - also do form rocks, just a different kind of them. Coal, sand, and even a soil, are also rocks, to mention some. "Salts" (like NaCl, known as halite) may also contribute to composition of separate kinds of rocks (say, halitite, carnallitite, etc.). Rock is simply a mixture of minerals. Minerals unknown from the Earth or impossible to be formed, or be stable, in the Earth, are expected to exist in many extraterrestrial objects. As such, new types of rocks, e.g., composed of crystalline ammonia-, methane, N2- and others-bearing ices, are to be expected to exist.
Hi , I like metiorites , if I had an earth peridot and a cosmic peridot ..can anyone tell the difference?...is there any ...subcomponent that is clearly astro ,rooted ?...know any good books ? ..I need science pictures ! Have a grande day , c yaz.
Wspaniały odcinek, dziękuję!
Your channel is amazing...
Ion propulsion, first time seeing Ceres, I always look forward to your videos Alex, thats why i dropped everything i was doing and watched it.
As always , Thank you Alex.
A 🇰🇪 fan.
Gulliver Foil's cover in Alfred Bester's "Stars My Destination / Tiger, Tiger" was that he was a rich man who owned this dwarf planet. Alex, if you haven't read this novel, do it ASAP, it's one of the best SF-books ever written. And thank you for your videos - they are incredible!
Alfred Bester is right up there with Ben Bova, Theodore Sturgeon, and David Drake as a Science-Fiction writer; he also wrote, "The Deceivers" and "The Demolished Man". By the way, the man's name was Gulliver Foyle.
@@fairwinds610 All I can think about is Robert A Heinlein's "The Rolling Stones", with its description of "Ceres Base" as the hub, safe haven, and clearinghouse for all the rough & ready asteroid miners and their families -- calling in to stake their claims, sell their metals and monopoles, buy parts and repairs; maybe visit the restaurants, bars, casinos, and whorehouses. It was juvenile fiction at its best and really put stars in my eyes.
Another fascinating video.
So many craters of different shapes - very interesting.
I've been enamored by Ceres since I was a kid. Today, I think it should be, as well as Pluto, considered a planet. An extra planet in the solar system would be cool and drive research funding.
Thanks. Love lil planets
This is extremely cool.
Awesome
Fascinating!
Thank you Benjamin.
Thank you very informing. gave you a thumby ups.
Great as usual
Thank you, Astrum ✨
Your videos are incredible
Looking at the pockmarked surface I’m reminded that earth would look like that were it not for weathering and tectonic activity. Just how many meteorites and asteroids have smashed into this planet is a little scary. But perhaps what they also best illustrate is the unfathomable eons over which these impacts have occurred. Awesome!
If you go to northern Arizona, you can see one of the most well preserved impact crater here on Earth.
Hi Scott. Yes I know the one you mean. It’s a classic shape. I like to imagine what that would be like to witness. Like a nuclear bomb I expect. I nearly got to see it a few years back while on a holiday in the US. But plans changed and I missed out. Cheers
Loved it.
