    When I was a kid, we were always taught about the major planets, but for some reason, their moons were only a side note. It wasn't until I started looking into the Jovian Moons, Saturn's Moons, and unique bodies like Ceres, Pluto, and Charon that I realized that the solar system was FAR more complex than it appears from a simple viewpoint. These moons are absolutely worlds in their own respect. Ganymede itself is literally bigger than Mercury and almost as big as Mars.

    A note for subscribers: Chances are you may have seen the content in this video before. All I've done here is edit the Galilean moons from the "Our Solar System's Moons" series into one video. I removed parts of the intros and outros, removed some repetition (for instance, I don't go into full details about orbital resonances every time) and removed the sponsors for a more seamless viewing experience. This is for people that want to learn about all the Galilean moons in one go, rather than specific ones. Also, about the Io section, I didn't rerecord the narration even though the audio quality isn't super great and back then I didn't pronounce my 'g's, however, this is actually my favourite "old" video of mine and part of the charm in my opinion was the narration, so I kept it. Anyways, enjoy!

    I remember when I was just a kid I knew which light in the night sky was Jupiter, and one night I got out a telescope I had from like Walmart or something, and I looked at it. I could see a tiny yellow dot with four little specks of light sitting around it. It was so cool. Also, can you IMAGINE the view from one of Jupiter's moons? Looking up and seeing that massive planet just sitting there?

    Picturing an ocean that is up to 150km deep is mind boggling. Whenever i'm on the highway driving and I pick a point in the distance, I measure out in my mind roughly how many KM away it is, and I picture being on the surface on the ocean, looking all the way down to the "bottom". This already astonishes me, and i'm only doing that with only a few kms in mind.

    What you didn't mention is that due to Europa's low gravity, a submarine capable of descending all the way to the rocky subsurface is do-able. It's about the same pressure as at the bottom of the Marianas Trench.
  • This is what great TV om Discovery and NatGeo used to be like. Now it has forever changed. This 4 part video series is amazing and world class. Well done. Some of the best content out here. Really appreciate your efforts to make these!!! I loved this so much and my interest in the inner Jovial moons are at an all time high!!!

    Jesus man, you had me glued to the screen, mesmerized. Numerous bits that I never heard of before, stunning visuals and editing. What an amazing content to subscribe to. Please never stop what you're doing.
  • @sweetiguess
    i loved this extended version... "yes, i do want to listen to info about moons for an hour, thank you."
  • @OleOlson
    Don't take this the wrong way, but I've been using this video to fall asleep every night since it was released. It has an ASMR quality to it, and is still a super good science video at the same time.
  • @raydunakin
    Very interesting subject! The video kept my attention despite being 45 minutes long.
  • @mcwarrington
    This is one of my favourite videos you've produced. Great pacing, fascinating topic, well narrated all through. Thanks for uploading, and best wishes from New Zealand!
  • @littlerelief
    The title of this video alone made my heart race... I love the Galilean moons so much that I have a tattoo of an early sketch of Galileo's that shows Jupiter with them all orbiting around it!!
  • @BrettCahill
    I never get bored of learning about these moons, love seeing these combined into 1 video!
  • @pedrororiz9910
    This was a spectacular video. Super informative, fun, easy to watch and well produced piece of information. I guess you've achieved that level of excellence because you love what you do, right? Keep up the great work and I sincerely hope you achieve your goals with this channel.
  • What an absolutely beautiful and excellently produced production- I found myself over and over through the video rewinding so I could re-hear and PROCESS the data-points and information being presented; this is not a critique but rather an applause of how fascinating and feature-rich this presentation was. Bravo. You have created a subscriber for life! I can't wait to get the time to explore your entire catalog. Amazing, and thank YOU!
  • This topic is fascinating to me. If I could travel our Solar System and on to explore the Universe I would do it in a heartbeat even if I knew I’d never return. Obviously time and distance makes it impossible but hey, I can still dream lol. Thanks for uploading this video.
  • @DefektiveEnvy
    This is such high quality content. I love thinking about how we’ve sent our senses (and even more powerful senses) far beyond our world to these outer places that we’d never see in such detail. But people have been looking up at them for centuries
  • @karenabel6218
    Thank you for a well done video. Interesting, informative, good visuals to help with your explorations. Well done. I love this channel.
  • @luminair11
    This is one of the best videos I've seen on interesting and superb images along with descriptions!
