Titan: A Desert Made of Water

The largest Moon of Saturn is the closest we've found to another Earth in the Solar System, but an Earth made of water.

One erratum noticed in the comments: The Caspian Sea is the world's largest lake, not freshwater lake. The world's largest freshwater lake is Lake Superior.

When I first learned of Cassini's end of mission, to my surprise, I actually cried. Slmost anything about man's exploration of space wets my eyes. It's all so profoundly beautiful.

Can't help but learn every time I tune in to this channel. Thank you.

Wow, little did I know what I would find when I clicked on this recommended video. Very impressed, and looking forward to more. Subscribed.

I couldn't help but laugh at your Attack on Titan pun, complete with the opening music to the anime. Spot on. Great vid as well. Now I have to go find the other vids in this series.

[reyzavala]

Excellent production! No annoying background music. Thank you.

The defining trait for a desert is the amount of precipitation received, not the amount of water present. Antarctica is the world's largest desert, and it contains lots of water.

Hurray the series continues. We live in interesting times when it comes to astronomy, well probably not just astronomy but ... I actually shed a tear when Cassini send it´s final signal to earth. You´ll probably need some animations yourself should your channel grow. Keep it up!

You do never disappoint! I really enjoyed the animated diversion on Dutch pronunciation.

[mbunds]

You pronounced “Huygens” correctly...you’re braver than I am!

I'm very happy to have found this channel. Some one recommended it in the comments of Isaac Arthur's newest video. Parallaxicality, you do an excellent job of making this fascinating and entertaining. After watching this, I went over to the SciShow to compare presentation and style, and I like yours much more. You go into detail, use good graphics without making it cartoonish, and you don't implicitly insult your viewers by dumbing it down. This is way, way, way better.

What a awesome video, loved it! Hands down the best documentary on Titan there is, I learned so much from this. Good job

[randomname]

i dont understand why this channel hasnt got more subs...it is a naration beauty
edit: thank you for the like

[rachel_v_k]

Excellent video! I enjoyed it immensely and I learned so much. This is one of the best channels on YouTube. Thanks and have a good night! 😊💕

Great video but your model of the water molecule is incorrect. The oxygen atom has two lone pairs of electrons, not one. The hydrogen atoms in a water molecule are actually occupying the corners of a tetrahedron. The angle deviates slightly from what you would expect in a true tetrahedron because of electrostatic interactions. In this way the electron pairs and bonding electrons obtain maximal spacing around the oxygen atom. Just FYI. 😀

PS I'm a chemist so I'm admittedly a little picky. However, please don't think I disliked your video. On the contrary, I don't know how you don't have more subscribers. Your channel is excellent.

[Phrenotopia]

This has become a great and highly informative video! I'm glad to be able to be part of it. :-)

BTW Your pronunciation of Huygens is actually spot on!

A note on the unique chemical properties of water.  Some of those unique properties that make water essential to life on Earth also make water hazardous to life on Earth.  For example, the fact that water expands when it freezes.  This property prevents lakes and rivers from freezing solid during the winter and protects aquatic life, but it also makes complex life on Earth sensitive to is partly why that aquatic life needs to be protected from freezing to begin with.  Because water expands when it freezes, it causes damage to our bodily tissues if the water in our bodies is allowed to freeze.  The expanding water-to-ice transition causes damage to our bodily tissues (ruptured cell membranes, torn capillaries,  etc., etc.).  If life were based on methane chemistry instead of water chemistry, it is possible that it might not be so sensitive to freezing.  Instead of killing a methane-based lifeform, freezing the methane might just cause it to go into a dormant state until it thaws and resumes its activities.  Heck, the lifeform might even be capable of functioning with a certain amount of solid methane in its system.  In that case, it might not matter all that much that methane exists in liquid form over a fairly narrow temperature range on Titan.  Freezing and thawing might just be part of its life cycle during the seasonal variations.

Ahh gosh yesss needed this! More of Titan😍🟠

[vallonskyles]

Fantastic video! A great amount of scientific detail, making it highly compelling, but easy to understand. Overall it's very interesting and informative and massively entertaining. Thank you!

[DushanChaciej]

Wow, this is the type of video I was looking for for quite some time, even suggested it to Isaac Athur. Video on how exactly life could look/work like on a totally different type of planet.
Love it! You've got a new subscriber
