Join Phil for a tour of our capital-M Moon, from surface features, inside to the core, and back in time to theories about its formation.

(8:49) I loved the end of this episode! It was kinda sweet. Go teenage students!!
LOL YOU AINT GOT NO LIFE! THATS WHY WE COMMENT?REALLY?WHO EVEN THOUGHT OF THAT?!
+Meredith hidalgo = i ♥ ur picture for comments (plus it was one small step!)
oh my god. everyone needs to watch this show before they're allowed to be adults.
08:45 The greys that have bases on the far side do not want us to travel to the moon. so….
The Moon is the only one, just like Venus is the only Venus. The Moon is the name of that object in English. Once we discovered that other planets had natural satellites, we decided to call those "moons", making a generic out of what had been a proper noun. Much like calling all facial tissue "kleenex" no matter who makes it.
Imagine if we had decided to call all other planets "earths". It would be the same kind of thing.
What if the crust anomaly was caused by a smaller moonlet that formed with the moon and when it finally collided it barely had the speed needed to cause serious damage so it sort of just splattered there
Do we need a bigger reason to go back?
the moon moo x3 moon when ur on the moon u say moo x8 u put ur hands on ur head and shake ur booty. la x3 M-O-O-N its never gonna go away as long as I live. its just gonna stay its lookin for and antidote never like its gonna see the day its a moon with an empty bite its a girl with an apatite the other ones just a solid girl its got more fightness as the world. okay okay that's enough Moon/Chica song
there going to be a war for the moon
Thank you Phil for sharing your passion.
Listening to you is always a pleasure : so damn interesting, and even beautiful. :)
I love this so much, it makes me so happy, I love space
omg
could someone tell me what happened with the planet that collide with the earth. Was it destroyed or something else?
That final speak touched mi soul
hi there how it is possible if i say "moon was seen from calgary canada and punjab india at the same time" several times?
both the Earth and the Moon look like pizza. Im hungry.
remember when the U.S. was going to cut NASA funding and then they changed their minds, realizing a good space program inspires generations of scientists? glad we kept our priorities straight.
I like -really like – CrashCourse. I absolutely don't like PBS/CrashCourse.
The link to the web site is dead :(
what if any effect would moonquakes have on the earths plate tectonics…are there in fact identified remains of plate tectonics on the moon? oh, this is comment 666… spooky…
Phil mentioned colonization of the moon it would make a great tourist attraction 🙂 the spaceships we design should be able to to build instead of ejecting boosters engineer them so they have a dual purpose that are easily converted to modules if it's possible so every time a spaceship lands on the moon we are able to add to the colony.
But the Fallen and the Hive control the Moon, so how did we ever go there? :p
i dind not know thare is all reday water on the moon
