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.

At the most elementary level the planets are taught because they are the most basic, similar to how an intro to geometry course wouldn't focus on trigonometry. The point is to inspire fascination so people are interested and look into planetary sciences like selenology (moon). As far as deeper science the moons of Saturn and Jupiter have been a huge focus for a while now because of their makeup and potential. Cassini changed our whole field, there is so much interest now from so many people and i love it

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.

One of the biggest things about europa and the fact that it may have life is that not only does it have all the requirements for it, but the environment is likely exactly the same as when life first developed on earth (deep, pitch black oceans with basically no surface contact around geothermal vents).

You should also be proud of yourself for even thinking these things. I know that may sound strange but most people live their entire lives without ever looking beyond their immediate surroundings and animal needs. Going back to the journey at hand: I was in the same place as you 4 years ago. I was terrified by the prospect of death and "missing out" on the potential future of our species. I did not seek any therapy or help but instead I sat, alone, and thought about it. Think about the vastness of everything and it's, dare I say, divine precision and magnificence. It all exists for YOU. Knowing how small we are is important but by no means are we insignificant or irrelevant. Where else in the universe do you see anything like love and compassion? Anger and malice? We have something unique and to use that for your benefit and others is in my opinion the meaning of life. How do I know this? Because I'm here, I'm here talking to you. I think you should not yet extend your thoughts as far as death and time. Focus on you and the now. Build a life and seek love above all things. This way when your time does eventually come to move through the door of death to the next stage, you will be ready. I hope and pray to the power that guides the flow of all things that you find love and peace in your life and that you live fully without fear, because there is truly nothing to fear. I'll end with a quote from my favorite poem: "Time is the school in which we learn. Time is the fire in which we burn." YOU are alive NOW. That's what is most important. I don't know you but I love you stranger. Go now and live.

This was very well presented and extremely interesting. Thank you.

I love watching your videos while I'm falling asleep. Your content is interesting, and your voice is enthusiastic yet calm and its just all so peaceful.

what impress me the most is how perfectly spheric Io is.

For me the most magnificent part of the space is the Moon, closest body to Earth. We tend to pass its presence, but it remind us that we are part of the planetary system and is the closest mark of cosmos we live in.

I'm so happy I found this channel just stumbled on it one day and I love it.

I loved this video! My favorite terrestrial moon is Io, it's geological activity is amazing!

Fascinating! Only exploration will answer questions while posing new ones. I would die happy knowing that life exists elsewhere in our vicinity.

The best video on the Jovian moons I've ever seen! Now I cant wait for a probe going to Europa for fishing.

Wonderful content, as always Alex. Always so well made and informative in a most intriguing way. Serene music too..thnx for this! Fascinating stuff.. would love to see something on the ice giants and Pluto...

Love your work my guy

Just a thought on Ganymede. Maybe the reason for the newer breakages being brighter is related to the ice probably forming before all gases could separate from the solids and liquids. Therefore newer craters would result in cracks with more gases.

So there's two ways planets are destroyed from impact or heating up from the inside

Thank you for the hard work you put into this fascinating informative video. Always found Jupiter and it’s moon’s to hold so many great things to discover and compare to our own planet.

Awesome.. Totally love these videos & the effort it must take to make them

great show as always alex

Fascinating video, thank you. Still, whenever I hear speculation about us becoming a space faring species and talk of colonizing other planets or moons, I'm struck by how easily we forget our symbiosis with our terrestrial bacteriological environment; the variety and number of microbes our bodies need to function.

I love your channel and you always do a great job. Keep up the great work.

I enjoyed this interstellar journey of mind expanding information. Very informative and fun to watch.

Excellent video! It's utterly amazing how much we have learned since I was a kid. I'm 58 now and the thought of seeing these worlds and their moons was the stuff of dreams. Thank goodness we still have plenty of highly intelligent and motivated people who not only dream, but make those dreams a reality!

Interessante demais !!! Quatro luas com alguma possibilidade de conter vida em uma delas. Seria bom se encontrássemos traços de vida em outra parte do sistema solar. Poderia ser uma prova de que vida é uma parte comum em nosso Universo.

Woah this channel is so awesome and interesting. Good job!!! I love this channel!!! Take care and have a great week 🌍💯🤗

Thoroughly enjoyed this condensed compilation video taken from your series on Jupiter's moons! You did an excellent job of cutting out the redundant concepts while keeping the important substance. Your video says our most brilliant scientists consider Europa as having the best (the minimal) conditions for life "as we know it." In this case, it's a very good chance the correct combination of liquid water, heat and organic compounds are present in Europa's subsurface oceans to support carbon based life. However, you pointed out several times the radiation of Jupiter is so high it would kill a person quite quickly. How does radiation this high factor in the debate over life on Europa? All things considered, I think if life is discovered it will be exotic and possibly silicon based. Also, Saturn's moon Enceladus is another place where life "as we know it" may exist. Like Europa, scientists believe Enceladus' subsurface oceans could contain that unique combination to support a potentially diverse microbial community beneath the moon's icy facade. However, I believe due to many harsh environmental factors, in the end were going to find its just too toxic for carbon based life. Yes, we know the unique factors of liquid water, heat and organic compounds are present on these moons. But until we place an actual probe into their oceans we can't tell for sure. If life is found, it's likely going to be very exotic. In fact our instruments are looking for carbon based life and cant detect the environmental factors to support silicon based life. And how could we detect silicon based life? We know its theoretically possible, but don't understand what environmental conditions have to be present for it to exist?

I think that the ice sheet on the surface would block a lot of the radiation from Jupiter. It's kinda like the idea of living in lava tubes on the moon

Jupiter has so much mass that its primary moons are fricken planets. Let that stew in your 🧠 LOL🤯

Incredible video! The best I've seen on the subject... Thank you for making this!

Wow. Alex, this is the best video you have ever made. Thanks for this!!!!

I love watching Jupiter in my 152mm or 6 inch reflector telescope. Using the correct lens eyepieces at 200x magnification and the sky cooperates I can see the moon's shadows go around Jupiter. The cloud bands and Big Red Spot show up well. Relaxing hobby and doesn't have to be expensive, my telescope used with shipping was $250.

Save your pennies and get an R2 revolution imager. About $300.00 and you get live video on the little monitor it comes with. You'll have control over exposure times, color saturation and a bunch of other stuff. The enhancement of deep sky objects is amazing.

@@booklover6753 I already have a VX mount and can track DSOs with extended exposures if I wish and have. I drive up to Bortle 2 skies about 20 miles north of town. I still prefer to look at the planets, Sun and stars myself because if I want to look at really good views of space I can use the Hubble catalogue or of probe pictures. There is a video by Backyard Astrophotography where he took a picture of Hubble's famous Pillars Of Creation in the Eagle Nebula. His photo matched Hubble's except for some blurriness cause by the atmosphere. Really impressive, but it took all night. For $260 I acquired two filters, a Beta H filter I see nebula pretty well with and with an Olll oxygen filter I can get decent views of Planetary Nebulae too. They are misnamed because when first seen in the 18th Century that's what they thought they were, they didn't know they were remnants of star novae.

@@MountainFisher Cool beans. I used a 6" F5 newtonian on a clock driven equatorial mount for years. My current telescope is way too heavy to transport easily (10" Meade LX 90 ACF UHTC). I put casters on the tripod legs so that I can roll it out of the garage on to my driveway. I use 25 feet of cables to USB the autostar controller into a laptop at a desk in my garage and control the drive with planetarium software. I started out using 1 1/4 and 2 inch eyepieces with both narrow band and broad band filters, but the light pollution at my house is just too heavy. You see, a larger aperture scope, while making deep sky objects more visually accessible, also picks up more light pollution and amplifies it as well. It took me a long time to save up for the telescope and eyepieces and the light pollution was a real problem. The R2 imager has built in software that filters out the light pollution for you without using any add-on filters. I should also mention that I use the camera at prime focus with a .5 focal reducer to widen the field of view. For a cheap real time astronomy video camera, it works amazingly well. I have seen hundreds of galaxies, nebulae, globular clusters and so on. Viewing the double cluster in Perseus reveals hundreds of individual stars that twinkle beautifully even though the field of view only allows me to see one cluster at a time. One night I was looking at the Dumbell nebula and noticed the image starting to degrade a little. I got up and walked out to see what was up and realized that the camera was still picking it up though light cloud cover! By the way, planetary nebulae come from old red giant stars expelling their atmospheres rather non violently as they die and contract, although they do resemble super nova remnants. My camera also picks up the white dwarf in the center of the ring nebula. I'm glad to have a chance to talk to another amateur astronomer. Best wishes and dark skys to you.

@@booklover6753 I live in Bortle 4 , but a ratio of 2.5 where a little further North is Bortle 4 with a .711 ratio. It is definitely darker there. Bortle is a fade from 4 to 3 as the 4 with .711 ratio is close to 3. Light pollution isn't a huge issue where I live except the Light Dome to the East, not to mention mountains so rising Mercury right now requires a drive. Best wishes to you.
