solar eclipse. that spectacle left a trail so wide that even those outside so-called path of totality experienced something that seemed, well, magical. here is abc's maggie rulli. >> here we go. here we go, here we go! oh my goodness! >> what an incredible window we have out of this spaceship earth. >> reporter: all across the country today, millions were captivated by this celestial dance. >> i've never seen anything like this before. >> reporter: for two and a half hours, the sun and the moon playfully waltzed across the afternoon sky. >> what an even. oh, my gosh. wow. >> it is happening right now. this is amazing. >> reporter: and then, if you were in just the right spot, seemingly pausing to embrace for just a few moments, a rare cosmic wonder for all to see. >> there is jupiter right there. that is jupiter. >> oh my god, that's so cool! >> reporter: for some

love-struck souls, it was the perfect chance to seize a once in a lifetime opportunity, to dance their own forever dance under the eclipse's shadow. >> i'd heard about this. i thought it sounded cool, and we'd been preparing for it for a long time. how about let's go get married during the eclipse. >> reporter: for courtney and keegan wright, from their very first date, the stars were aligned. take me to the conversation you guys had when you said let's get married, but let's get married during totality. >> okay. so i was not a fan for it. are you kidding me? >> reporter: so what won you over? >> as the months kind of went on, and talking about it more, okay, i'm kind of getting excited about this. this is going to be different. but now that it's here, i'm actually really excited, wedding dress and all, hair and makeup to the t. >> reporter: leading them to celebrate their vows right here in russellville, arkansas at an event dubbed the total eclipse of the heart festival. and let's be honest.

an object, a shadow is cast. the closer the moon, the longer the duration of totality. >> reporter: all along the path of totality, my abc friends and colleagues felt what i felt, moments of awe and wonder. >> and there it is. >> reporter: starting on the western coast of mexico in the city of mazatlan. >> i think this was even more remarkable than what i was expecting. >> reporter: where americans like amy traveled all the way from new jersey to experience the first moments of the eclipse hitting land. >> it's amazing! amazingly beautiful once in a lifetime beautiful! >> reporter: the massive attention bringing much needed business to many parts of the country. in del rio, texas, local winery even created a special blend just for the occasion. >> we actually created this wine. it's called the eclipse. and we're going to be enjoying this for the next 20-something years. >> reporter: remember the last time we were all told to look up?

>> mr. president, how's the view? >> reporter: it was 2017, and that was the first total eclipse to hit the continental u.s. since 1979. so what makes an eclipse so special? time for a science lesson. the earth rotates on its axis, making a full turn every 24 hours. the moon circles the earth every 31 days, and the earth and the moon rotate around the sun every 365 days. >> so the sun and the moon, even though they are very different in their sizes, because the sun is 400 times farther away than the moon, that makes the sun 400 times smaller. so in our night sky, they look like they're about the same size. >> reporter: the moon has to move directly between the earth and the sun in perfect alignment for an eclipse. and it has to be during a new moon. the sky will darken as if it were dawn or dusk, and you'll only be able to see the sun's outer atmosphere, the corona.

>> the corona is the sun's outermost father. so when you look at the solar eclipse, you see streamers. >> reporter: if you were lucky enough to be in the path of totality, you were able to look directly at the sun, exactly what your parents told you not to do at a kid. >> the rule for looking at the sun is never do it without proper eye protection when any part of the sun's surface is exposed. >> reporter: your fellow sun gazers aren't the only ones affected. plants and animals are known to react too. i'm note just talking about fido and fluffy. >> and malls and plants take their cues from the sun often. what happens when the temperature starts to drop and it gets dark? those animals that don't want to be awake at night go to bed. birds will roost. and those that are nocturnal, they'll come out. >> reporter: this is the small city of carbondale, illinois, population about 21,000. but for the folks who are lucky enough to be from carbondale, they've gotten to see an eclipse

twice, in 2017 and again today. >> look, there is the ring. >> no, way! >> yes, look at the corona. you can see the corona of the sun. >> reporter: they've been preparing for weeks for the influx of umbrafiles, the proper name. >> we are approaching totality right now. >> reporter: moments of total darkness comes to indianapolis. >> it's incredible to think about the sun, the moon and the earth natural a perfect line. >> reporter: my friend and colleague gio benitez couldn't help but get swept up in the gravity of the moment. >> and here everyone is together. nobody is divided. everyone is unified, and looking up at the sky together and seeing that we really are this small on this planet. >> reporter: and by the time it reached new york city, even though it wasn't in total darkness, people were still going out of their way to catch a glimpse. back in arkansas, where courtney

and keegan are writing the next chapter of their love story, keegan and courtney are among the 108 couples pledging their love to their one and only. >> we got suitcases and one that's empty in case we don't know what we're coming back with. >> you may seal the sacred union with a kiss. >> reporter: moments after saying i do. >> congratulations, y'all. >> reporter: the newly wednesday all turned their eyes to the sky. and shared their first dance. >> much mother than what i imagined. this is just breathtaking. it's like nothing i've ever seen before. >> reporter: now, if you're watching all of this and getting just a bit jealous because you didn't get your chance to sit in the cosmic shadows, well, your next shot at seeing a total solar eclipse in the continental u.s. won't be until 2045. >>. >> byron: just wow. moments millions shared and
