Uranus & Neptune: Crash Course Astronomy #19

Today we’re rounding out our planetary tour with ice giants Uranus and Neptune. Both have small rocky cores, thick mantles of ammonia, water, and methane, and atmospheres that make them look greenish and blue. Uranus has a truly weird rotation and relatively dull weather, while Neptune has clouds and storms whipped by tremendous winds. Both have rings and moons, with Neptune’s Triton probably being a captured iceball that has active geology.

Shout out to Neptune for being the only planet in our solar system found by math. Humans can be pretty smart when they want to be!

[WiseWik]

I never ever want these series to end. Simply extraordinary subject with Phil as an amazing host.

[DearDiaryCaro]

This is by far my favourite crash course. Could listen to Phil aaaall day long.
"It has rings but, shocker, they're weird."

[mahmoudyzadeh]

interesting tid bit - Uranus is the only planet to be given the name of a Greek god rather than a Roman one.

[samovarmaker]

"Luckily that name didn't stick"
...
At least we can say Georgium Sidus without being laughed at

[michakozowski]

Despite how super awesome this series is, and how greatly Phil Plait deliveres - I just love his surrounding - Kerbals, books, legos, all together :)

"Where the solid ones, will, errgg... Float, like an eughhh, diamondberg" Best quote of all astronomy time.

[thebloodyblock]

"i'd avoid breathing through your nose on uranus"

I don't know if this pun was intended or not

[joeschmoe]

FRY: This is a great, as long as you don't make me smell Uranus. Heh heh.
LEELA: I don't get it.
PROFESSOR FARNSWORTH: I'm sorry, Fry, but astronomers renamed Uranus in 2620 to end that stupid joke once and for all.
FRY: Oh. What's it called now?
PROFESSOR FARNSWORTH: Urectum.

"Like it's green brother, Neptune..."  6:40

"Who the F is Hank?"

"Hank is the outermost planet in the solar system, with an atmosphere of primarily hydrogen, helium, and methane. Hank is the guardian of the solar system's nether regions."

[TheMrzippie]

Did he just tell me that Uranus got wacked hard?

[potawatomi]

Phil your videos are great: educational, smart and really well narrated. Thank you.

[Coastfog]

I can't express how much I enjoy these astronomy lessons

[Ishygog]

It's still weird that they called it Uranus, considering that that's the Greek name. The roman name is Caelus. So many shitty jokes we could have avoided if they just stuck with the Roman nomenclature...

[jeremyj.]

Both planets look so beautiful. Makes me wonder what it would be like on the surface. What a pity we humans are so squishy :(

[markusbina]

One thing why I really enjoy "Crash Course Astronomy" is the fascination and excitement Phil brings into the show. If just every teacher I had in school was this absorbent of my attention. This course is almost totally free of general opinions or opinion at all, except that astronomy is fascinating, which is in stark contrast to the shows by Hank Green, which are almost only composed of his opinion.

[FridgeMaan]

So you're saying that Uranus has a river of diamonds? Neat.

[WankersCramp]

I cannot tell you how aggravating it is to have an intelligent conversation with someone only to mention Uranus and for them to smirk.

[InsomniacOvrLrd]

I love crash course, and have watched literally every video on the channel.

But the topic in this particular run is very interesting, and i look forward to these episodes every week.

Thanks guys.

I WAS looking up a ship video for Sailor Moon but this works too
