    I darken over time,I’ve fallen over crater walls

  2. databang

    Thank you Benjamin.

  3. Sherylin

    WOOHOO, finally. Thanks Astrum :)
    EDIT: Ceres is 940 km in diameter for those who want to know :)
    It has one-fifth the mass of Earth’s Moon.

    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!

    I love you so much!

  6. Florin Pandele

    So Ceres has a dimple, and a very (n)ice one 🙄. Any space dermatologist out there?

  7. david johanson

    Thank you very informing. gave you a thumby ups.

  8. Scott Soenksen

    The perpetual “suprise” would come to an end if they were not Darwinists.

  9. Trex531

    Great video Astrum, keep on! 👏👏

  10. Nunya _

    You Are Awesome! Thank you so much. Your space vids make me happy. Please keep doing this.

  11. Tomas Derville

    Thats Soo Cool!!!

  12. Rade-Blunner

    “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.

    This looks CERES-ously cool!

    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! 👍

  19. Tom-Pdexter555

    For the love of… Nasa take your tiny budget and instead of poking death wandering rocks, start drilling on Europa or start fishing on titan !

  20. Rafa Gonzalez

    ¡Excellent video! I didn’t know about the salt trails 👍

  21. Abhishek Dev

    Loved it.

  22. Conium Maculatum

    Is this a reuploaded video? I have this deja vu feeling.

  23. Luuk Breedveld

    Great video as always, just a question; why dont you upload in 1440p and 4k?


    Another great informative piece of content and thanks for the vpn offer

  25. S p

  26. Abhijit Dhar

    Woa that’s seems interesting 74 dumb nails

  27. Adventures with Dogs

    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!

  28. Bry Byrne

    Can I ask. ” how the hell do they know what’s under the surface or how thi k the crust is or what the core is made up of. It’s all just speculation they don’t and won’t know until they go there and drill or map it or something.

  29. Thepher

    You and Anton and Manley are like my holy trinity on youtube <3

  30. Mike Mann

    Brilliant video, thank you. A size comparison of Ceres and it’s features would be enormously helpful.

  31. Jimmy hall

    It’s lost moon landing data?

  32. Michael Kurse

    The bright spots look like salt, chalk or ice deposits.

  33. Ross Payne

    The moon of the destroyed planet that is now the “Asteroid belt”

  34. Big, Not Good

    Remember the Cant!

  35. plenum222

    …left in a stable orbit around Ceres… That’s perfect.

  36. Marisa Batista

    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…

  37. Nas Qad

    Ceres has a pimple it’s going through puberty

  38. Brian Jury

    Extremely interesting, and could ion propulsion be used here on planet to reduce need for fossil fuel?

  39. Marlin Juslon

    I saw a small pop from one of those spots on the sun yesterday. It looked maybe earth facing and could be why we got a bump in earthquakes. Merry Christmas to you and the family.

  40. Pablo Smith

    ‘Some of the cracks are relatively young, perhaps only a few hundred million years old.’
    Now go tell that to your sister-in-law who always complains about her age and why she should get a facelift.

  41. James Harder

    Excellent info; thanks for sharing.~*

  42. Éric Jacques

    Wow, look at the hexagonal crators!

  43. Joey BoX0RoX

    Sad ending to an incredible mission! Thank you for the update! 👍👍

  44. Pieter

    This is extremely cool.

  45. Simon Frampton

    Oh my lord it’s just another chunk of rock

  46. Kevin Harris

    So cool….remember hearing about ion propulsion decades ago.

  47. Amayii

    “What did NASA’s Dawn discover on Ceres?” – Hopefully no protomolecule

  48. SpaceRider

    The bright spots are aliens partying and chilling gzzz

  49. Chris DIYer

    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! 😄

  50. Victor Boliviet

    I recognize that music….. that chapter!!

  51. Flameblade69

    I always wanted to know, why is is that they never take actual “video camera” type things on the probes we send to space or is that not possible?

  52. thestarsinsideus 83

    Thank You for a no-nonsense channel of fascinating content, always creatively delivered.
    I’ve felt for many years that all people should be as interested in the universe as they could be about anything else.

  53. fogggygyrl

    You explain more about sublimation – it’s an interesting process where ice vaporizes into a gas without first transforming into a liquid.


    ?????”: ..?SIRIUS!!/??”

  55. John Shipp

    Love your videos Alex. Your channel is the only one I know of that talks about the finer insights of our space exploration….

  56. Bill Seidel

    And a perfect video for Sunday morning with my coffee ☕ 👍🌴

  57. Phyl

    Fantastic view of Ceres. Great detail of surface features.

  58. alborada777

    Great video. Dexter would agree: Ah, what a fine day for science!

  59. Dr. Greg Rothschild

    This video is a lie!!!! What they found on ceres was my half-eaten pizza. If i knew you guys were coming I would have cleaned the place up a bit 😆 Ok, but seriously, this is a great educational video.

  60. Julian Bouquet

    Ion-Thruster: I love it!

  61. Uraz ATEŞOĞLU

    Thanks for the video. I was wondering about that planet if it is different from any other moon. You are the best Alex.

  62. ReinhardB100

    Ceres. One of my next destinations in Kerbal space program

  63. Raul JR Lara

    This is exactly why I watch your channel. Just learned something new today . I never knew this planet existed . Thanks Alex

  64. Jerry Rupprecht

    Ceres is a lot more interesting than Dres from KSP

  65. Gamechanger 2.0

    Perfect video for a Sunday evening!

  66. Wally BALDEMOR

    For me, the Cutest dwarf planet

  67. Roland Brune

    Love the high quality of information from this chanel. Well done!

  68. SpaceMaze

    Ceres has always been so fascinating to me I really love the video !!

  69. Canadian Man

    Wow, very informative and wonderful. The white spots on Ceres looks like ice water, they are in the middle of a recent crater. So they are salt, interesting.

  70. Molly LittleBird

    This is one of my very favorite channels and one I always go to right away. Thank you. Your channel is without a doubt awesome! And the info you provide is interesting and informative. And the picture quality is without equal. You rock! Thank you Alex!

  71. aformalevent

    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!

  72. θ Xenon θ

    Cant wait until we get the resources if we havent already started mining them

  73. Gustavo Alonso

    Ceres is one of the brethren moons from Deadspace, beware!!!

  74. Gabriel Olivares

    one word: METROID

  75. RyllenKriel

    A seriously good series of images on Ceres. Truly important knowledge of our lesser recognized orphan dwarven neighbour to trigger our endorphins.

  76. Daniel Lipa

    Amazing video, Yours voice is so relaxing. Keep going it’s great content.

  77. Shadow 133

    Wrong target. We need a probe sent to Phoebe immediately and destroy the protomolecule!

  78. PTNLemay

    I thought people would be making more jokes/references to the Expanse.

  79. SnoopyDoo

    7:54 I’m sure it was giant gophers who dug up the earth and piled it next to their hole.

  80. Robert Ruork

    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.

  81. The Exoplanets Channel

    Perfect video for a saturday evening 👌

  82. Michael Hull

    Still waiting on a detailed survey of Uranus.

  83. Mike V

    Congrats on your regime change, I wish the best for my brothers across the pond!



  85. Eros

    2:56 Yup, That’s me.

  86. Massimo O'Kissed

    8:08 Dawn heads off towards Betelgeuse :)


    One of the things I love about your narrating is I can tell you’re smiling!

  88. WizzardOfPaws

    I really look forward to astrum. Every new video is a wonderful fun adventure so well done and so well put together

  89. Steel Man

    It would be awsome if there was a temple on Ceres

  90. Just Vienna

    A thousand years from now our offspring will be looking at this video on a museum on Ceres
    If we dont wipe ourselves out before then

  91. cliff

    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.

  92. Eriamjh 1138

    Was it the protomolecule? It was the protomolecule, wasn’t it?
    Watch The Expanse!

  93. Nicky Walker

    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

  94. Bell's Theorem

    If something appears uninteresting and boring, It just means you aren’t looking close enough.

  95. Mario C

    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.

  96. Philippe Nachtergal

    As long as they don’t find the proto-molecule, I’m ok.

  97. Jimmy's Old Time Radio Show

    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.

  98. Eric_of_le

    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.

  99. RLB

    I Ceresly like this channel. Thanks Alex!
