Growing up in Zimbabwe I was fortunate enough to see 2 full solar eclipses in the early 2000s. It was a truly awe inspiring thing to behold. Some cows in a nearby field began panic and rushed to the river to drink as the is what they do toward the end off the day. They were obviously confused by the rapidly darkening sky.

Does anyone know a good place too find info on future solar eclipses?

PP: "... and we call it the umbra, which is Latin for, you guessed it..."
Me: "UMBRELLA!"
PP: "shadow."
Me: "... *coughs nervously"

My family drove 10 hours to witness the Great American Eclipse in totality. During the long arduous road trip my kids were complaining about why I made a big deal about needing to see it in totality. But when that moment arrived they were in absolute awe of the event. They eagerly asked me when will we do this again. I felt quite accomplished as a parent that day.

5:45 I can totally see Rhett and Link doing this.

Oh man, it's been a long time since I watched CC Astronomy. And while probably everyone knows what an eclipse is, Phil still manages to make this video really interesting because of the LOADS of new info that a normal person might not be curious enough to really research about. It also really helps that Phil manages to keep a clean, easy pace to listen to. So really, thanks! I've learned a lot.

And THAT´S when you attack the Fire Nation

Rhett and Link! I love this now
And I can imagine them doing an entire episode on eclipses.

Sorry this one's a little late! We had to get some graphics just right.

My parents kept me out of school to watch the May 30 1984 annular eclipse in a huge shadow box they'd built.  Hands down the best truancy ever.  The thing I remember most is the discovery that when you're in the blotchy light in the forest or under a leafy tree, what you're actually seeing is the result of dozens of pinhole cameras made by gaps in the canopy, all casting images of the sun on the ground, and you'd never know that except for those rare times when the sun is something other than a disc, and the ground is covered in little crescents.

And Phil:  You are invited to come to my house on August 21, 2017 for an eclipse party.

[TheFireflyGrave]

Wow, great episode.  The parallel drawn between the 'blood moon' and sunsets really helped me understand this stuff better.

[Zerepzerreitug]

I like the idea I read once that if we ever encounter aliens and have to show any kind of "sign" or distinctive that will separate our little planet from all other civilizations, we should use an image of our solar eclipses. The odd coincidence between the moon's size and the sun's size, relative to the expected rarity of civilizations, makes it likely that we're the _only_ planet with a civilization in this galaxy where this happened.

[zapp]

That was definitely Rhett and Link! Probably doing their new episode, "Will it Retinal Damage?!?!"

[RupaniJuvell]

At age 15 I had three international astronomy Awards and at age 40, (now) it's easy to be envious of someone with so much incredible experience like working on the Hubble. I've enjoyed all of the Crash Course episodes-they are fun for me to watch with my fiance and get us talking about my favorite subject, science, but today I found that someone had cause to be jealous of me because I was at the total solar eclipse in Mazatlan, Mexico in the early 90's. It was the longest totality of my lifetime. A full two minutes! So thank you for the episodes, thank you for the information, and thank you for the boost to my self self-esteem!

[benaaronmusic]

YES! Thanks for the Eclipse information!
I've been waiting for August 21st, 2017 for almost a decade!
It's so close! 
(BTW, love the Rhett and Link animation at 05:41)

Me: HELL YEA!

I want to thank you for the rhythm of your speech in this episode, it was the first time I felt like I could breath.  I think you put more pauses in and it's a much more enjoyable experience.
