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.

[@cortster12]

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

[@TheTaintedTango]

[@kalibrador]

[@kyphilburg]

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?

[@Zerepzerreitug]

this page by NASA has a list of eclipses for the next decades and centuries. Click on the red link date and it will show a map showing where the eclipse will be. eclipse.gsfc.nasa.gov/solar.html

[@hyrdrogenalpha]

Arturo Gutierrez This page is by Fred Espenak which NASA has nothing to do with except to turn it on and off. Espenak retired in 2009 from NASA. Espenak updated the website, to a point, because NASA threatened to take it down back in February 2014 (which they did for ten days). Eclipse information is still outdated from 2020 and onward. If you see any orthographic map dated Fri, July 2 -- it is outdated.

[@Zerepzerreitug]

hydrogenalpha damn...

[@hyrdrogenalpha]

Arturo Gutierrez He did start his own website after the NASA threat last year www.eclipsewise.com/eclipse.html ,but again the info is dated starting at 2020.

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

[@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.

[@arturocevallossoto5203]

What if they live in a moon orbiting a gas planet?

[@Zerepzerreitug]

Arturo Cevallos Soto I'm pretty sure they would have some weird-ass astronomical coincidence in there too to brag about.

[@chrisnotaperson8127]

Have you read Transition by Iain M Banks?

[@Zerepzerreitug]

Chris notaperson It pains me to say I've yet to submerge myself into the _Culture_ series. Does it mentions something like this in there? ;)

[@chrisnotaperson8127]

transition isn't one of his Culture books, though they are all amazing. But yes in transition there is a character that is obsessed with the idea of "instead of looking up during an eclipse, look around"

[@crashcourse]

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

[@nicholascrass2555]

Also the point of greatest totality will be in Giant City State Park in Illinois.

[@davidtimothy7319]

If the moon detaches itself from the earth 4cm a year, then wouldn't gravity between them loosen, accelerating the moon?, and by how much is the acceleration if so, and at what point would the moon kind of, fly off on it's own?

[@BlokenArrow]

Dr Timothy The gravitational pull on the moon would lessen as a factor of the square of the distance, but it would still be attractive, which is slowing the rate in which the moon pulls away from the Earth (or vis versa). As the moon is already tide-locked, it is unlikely to be able to pull away from the earth permanently. In a billion years of so, the moon will have pulled away to its maximum distance, and the earth's rotation would have slowed to the point where the moon and earth will be tide-locked to each other and will be caught in a perpetual staring contest over what is left of New Jersey (after the revolution has destroyed it).

[@davidtimothy7319]

[@JoePatterson]

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.

[@hyrdrogenalpha]

I watched the May 30th eclipse in Greeneville South Carolina in a cemetery. A cold windy day with telescopes setup among the graves. First time I ever saw shadowbands!

[@flameoso]

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.

[@EandCheckmark]

[@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!

[@TheFireflyGrave]

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

[@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)

[@RainAngel111]

does anyone ever think of how fucking crazy it is that the moon and the sun are almost the exact same size in the sky? What were the chances that we'd have a moon and sun the exact size that they are, at the exact distance that they are? The fact we can have eclipses at all is fucking amazing.

[@arturocevallossoto5203]

It really isn't if you think about it. If it wasn't that we would find awe in another things. "Omg, we have a planet with rings. What are the odds, right?!"

[@Mostlyharmless1985]

There's a gas cloud out there, that if you took a bucket of it to earth where you could smell it, it would smell like rum, and taste like raspberries. My point is, the universe is a big and strange place.

[@RainAngel111]

yeah. that'd be pretty amazing too. Planets, like people. have some amazing things that make them special and interesting. killjoy...

[@RainAngel111]

Mostlyharmless1985 but it might also burn your face off

[@basslinedan2]

Just chiming in 2 years late to say you're absolutely right, it is amazing that our moon and sun are at just the right relative size and distance for eclipses. And they won't be around forever, eventually the moon will drift too far away for totality. Sure there are some very odd things out there, and lots of planets have ring systems, but I bet very few have proper solar eclipses.

[@divinelyautistic]

Well considering that you get a CURVED shadow on the moon during a lunar or partial lunar eclipse, will show that whatever is casting the shadow is round. A shadow is a replica of the object itself. So if the shadow is round then the object is round, pretty simple.

[@minyaw1234]

I've seen a total solar eclipse in 1999 in southern Germany. The clouds just cleared half a minute before the total eclipse, so I wasn't able to see how it got to it but I saw the main event with my own eyes. It was a great experience.

[@gaiusbaltar4850]

Same day, same time, different spot. My mom had bought special glasses, but I didn't have them with me, because I was playing in the street. As for you, the clouds cleared just in time for the event. I had no glasses, but I still wanted to see the eclipse, so I had to use my bare eyes. That was very stupid of me. My mom was so scared for my poor little eyes. Fortunately, I had no sequel, but I wouldn't do it again, that's for sure. That was Belgium 1999, one of the best years of my life, though I don't remember why that number inspires me such a good feeling. More than ten years later, what the Moon and the Sun together couldn't do to me, the monitor of my computer did. And I don't even intend to stop. How pathetic is that...

[@fpoggesi]

I must have been in a field just downwind of you because that day I had the pleasure of experiencing the perfect alignment of Sun, Moon, and clouds leading to me seeing less than nothing.

[@gaiusbaltar4850]

Frank Knoller That's quite an alignment. I'm glad it didn't led to the end of the world.

[@Nariom]

I saw it from east France that was so amazing ! I remember when the sunlight went off and the village down the hill suddenly lit from automatic public lighting ! The sky was perfectly clear and they've been handling special glasses to everyone all over the region so we could enjoy the show. I'm sorry for Phil Plait since he said he never had the chance to witness that.

[@commando1124]

Ha! We had clear skies in Flanders

There's clearly a LINK between staring at an eclipse and damaging your RHETTINA. A year late, but totally worth it. I'll show myself out.

[@ChrisSeltzer]

Can we all agree the guy teaching Astronomy is amazing? I don't know what Phil's background is but he's such a good teacher. It makes up for the terrible teaching in Government and Politics.

[@Mostlyharmless1985]

He's written several books on Astronomy, blogs about matters astronomy on a site called Bad Astronomy, and for a time was the president of the JREF.

[@roostewrum]

He was also an Astronomer for the Hubble Space Telescope before leaving to take up writing and education.

[@alexjones4338]

Rushing through the material without letting students time to take it all in is not good teaching practice. Take notes from the late Richard Feynman or George Levy. They knew/know how to teach and engage with students unlike Phil. Guaranteed you didn't get 50% of what Phil said without having to rewind back.

[@xyvaz]

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.

[@Fhantom99]

As always, thank you very much, Phil, for making this astronomy lesson! Of course, big thank you to all the others at _Crash Course_ working with all the graphics and stuff for these astronomy videos. The moon and the sun are really interesting. Do solar and lunar eclipses happen on other planets too (at least, other planets in our solar system)?

[@keyeraboyd6996]

I like to think that Saturn has them alot since the amount of moons it has

[@departed402]

I was in the penumbra last year, and it was magnificent. The cloud cover that day was such that you could look directly at the partially eclipsed sun through the thin layer of clouds.

[@TroyEagan]

The Rhett and Link cameo was hilarious.

[@lil_stargaze4303]

I live in Wyoming, we had a Solar Eclipse 2 years ago I think it was? We didn't see the total eclipse but we notice that the shadow of leaves became cresented aw the moon across the sun, which I found very intriguing

[@Belikemoe]

it is really interesting how those ancient greeks knew for a fact that the earth is not flat but rather a circle or sphere based on their view of lunar eclipse. in 21st century we call ourselves "civilized" nation yet we have thousands of people that still believe the earth is flat, and we have so much technology and advancements in science.

[@Zerepzerreitug]

maybe it's not so much "dumbed down" as much as you're too knowledgeable of this topic already. A coworker had trouble distinguishing between Jupiter and Saturn from a photo, so I think there are a lot of people out there who would find these videos perfectly suited.

The other courses have been AP/college intro level; I can understand this being a little different since there isn't AP Astronomy, but so far this series has been middle school level. It is only the fifth episode, so I'm not giving up, but so far it's been a little disappointing. Middle school science classes only spend a few weeks on astronomy before moving on to something else, and that was the last formal astronomy education I received. Hopefully CrashCourse will get into something more advanced soon.

***** that's exactly what I meant. The info in this series is not on the same level as CC Bio or Chem. I'm not their target audience, but I think the material provided so far is too simple for someone who has an active interest in astronomy.

[@chinito77]

damnage97 It's meant to cater to middle school to high school students, that's PBS's target audience. Don't forget, that it while may seem simple to you, there are plenty of under-educated kids in the US.

Sufficiently analysed magic is indistinguishable from science.

Are you trying a variation of "A sufficiently advanced technology is indistinguishable from magic"?

I hope you saw a total eclipse today Phil! I did in South Carolina and it was truly magnificent!

[@thajiveone]

Me too! We drove 3 hrs from Ga to SCSU in Orangeburg. It was amazing!

[@DARIEN792]

i've seen a total solar eclipse once... I was like 7 and lived in my home country Guatemala... i was eating when i heard my mom talking about it and that its a rare event (it was on the news too), i stopped eating and went outside with my friends to watch it and there was people watching it too, they were warning us to be careful cause we could go blind... i'll never forget its an amazing moment i hope that one day i can become an astronomer and tell this story to younger generations.

Pro tip: Looking at the sun is 100% safe through a telescope. huehuehue

[@BritishMetric144]

ONLY if it has a solar filter!

[@MadrigalSingers-]

I trusted you

[@chrisc1140]

I actually burned a hole in my solar glasses looking through a telescope with them. We didn't have a cover for the telescope itself but I thought my own would be enough. Thankfully I jerked away when I saw a bright flash and so didn't do any damage, but those lenses died to protect my vision. F

Who else is going to travel to the path of totality tomorrow??? GREAT AMERICAN ECLIPSE!

[@ordinaryJeff]

I did. Drove from WA down just south of Portland to watch it. Awesome experience.

[@sofiacummings5574]

I was in the area that only got about 80% totality, but it was still awesome (I was scooping ice cream at the county fair at the time of the eclipse, every so often I would go out to watch it for a few minutes)

James Bone I was there in California, Missouri

[@Tayatalkz]

James Bone I saw it and have pictures of it

[@jeremysartin745]

James Bone I did. it was amazing.

[@RoddyBear143]

I was in Carbondale Illinois for the 2017 eclipse. Never seen anything like it before. Pure amazed

[@ianhubbard641]

Saw it August 2017. I'd agree with his friends, it was the most spectacular thing I've ever seen

[@jowil93]

This series honestly couldn't have come at a better time. I've just started an Astronomy course at my university and my professor is absolutely hopeless, I needed something like this if I want to pass.
