Why people get so excited about a total solar eclipse

A solar eclipse happens when the moon’s
shadow falls somewhere on the surface of Earth And a lunar eclipse is the opposite — when
the Earth’s shadow falls on the moon The two sections of the shadow, the dark umbra
and the partially shaded penumbra, their placement determines which type of eclipse
we can see from Earth. But not all eclipses are made equal. The most spectacular, the one for your bucket
list is a total eclipse of the sun. A total solar eclipse begins as a partial
eclipse. You’ll notice trees projecting the crescent
sun, and shadows becoming sharper than normal. The landscape darkens to a bluish-grey and
 you’ll start to feel the temperature drop. From the west, the moon’s shadow rushes
toward you like a silent storm. Look up and you’ll see the last sliver of
the sun sparkling like a diamond ring, before it’s broken into a string of beads
by the moon’s rough terrain. Now you can see the pearly glow of the sun’s
corona and the pink and red light from the hydrogen gas of the chromosphere. Together these make up the sun’s outer atmosphere,
and a total solar eclipse is the only occasion you have to lay eyes on it. This is totality and if you get a chance
to see it, you should. The moon orbits earth every 29.5 days, but
we don’t get eclipses every month. That’s because the moon’s orbit is not
in line with earth’s orbit. it’s tilted about 5 degrees. That doesn’t seem like much but keep in
mind that the scale of the model we’re showing to you is way off. If the Earth and moon are this size, the
distance between them should be around 10 ft. At this distance, 5 degrees is enough to keep
the moon’s shadow off of Earth and the Earth’s shadow off the moon most months. So why do we ever get eclipses? Because there are two points where the moon’s
orbit crosses the sun’s plane, called nodes. And as the Earth moves along its annual orbit,
those points line up with the sun about twice a year. As the moon passes between the sun and Earth
at that time, we get a solar eclipse. When it’s behind Earth at that time, we
get a lunar eclipse. There are a ton of orbital quirks that make
predicting eclipses really complicated, but in general we’ll have a few solar and lunar
eclipses of some sort and a few lunar eclipses of some sort every year. But you’re more likely to see a total lunar
eclipse in your lifetime than a total solar one. The totality of a lunar eclipse can last well
over an hour and it’s viewable for anyone on the night side of earth. The moon often turns red during a total lunar
eclipse because our planet’s atmosphere scatters the shorter bluer wavelengths of
light, while the longer, redder wavelengths pass through. Or to put it another way, a total lunar eclipse
projects all of the world’s sunsets and sunrises onto the moon. Total solar eclipses seem much more rare because
totality lasts just a few minutes, and although Earth gets a total solar eclipse every 18
months on average, each one is only viewable by less than half a percent of Earth’s surface. Eclipse chasers travel all over the world
to put themselves in the path of the shadow. In a total solar eclipse, the moon precisely
covers the sun from the vantage point of some place on Earth. This is possible because by coincidence, the
sun and the moon appear to be about the same size in our sky. While the sun is 400 times bigger than the
moon, it’s also about 400 times farther away. But this alignment isn’t constant. the moon has an elliptical orbit. Its size varies about 12% throughout a month. When it’s closer to us, we can get total
solar eclipses, but less than 30% of solar eclipses are total. More often, we get partial eclipses, where
the alignment is a bit off, or annular eclipses, where the moon is too far away to fully block
the sun, leaving a ring of sunlight around the moon. In the far future, earth will only get annular
and partial solar eclipses because our moon is moving further away. We know that because Buzz Aldrin and Neil
Armstrong left mirrors on the moon in 1969. Astronomers bounce lasers off those mirrors
to measure the moon’s distance. And that’s how they found out that the moon
is moving away from Earth by more than 3 cm per year. So in a billion years or so, whatever creatures
live here will witness Earth’s very last total solar eclipse. “We can see on the Radio One screen, a fantastic
total solar eclipse taken from the pictures above the clouds.” “This is just fantastic.” A lot of early civilizations feared eclipses. They were often seen as an attack on the sun
or moon by the forces of darkness. But now that we understand our place in space,
eclipses are an occasion for awe, and for gratitude. All over the galaxy rocks are casting shadows
on other rocks. But only here, as far as we know, is there
someone to notice them.

  1. "By coincidence the Sun and Moon appear to be about the same size in our sky"

    If people only knew the mathematical probability (or should I say impossibility) of things like this all coming together by "random chance" ugh

  2. So if the moon's orbit has two nodes that are sort of fixed to the rotation plane, why are the moon and solar eclipses precessing through the years like showed at 2:09? So, why aren't we getting the eclipses only at the certain point in a year, and instead we have possible eclipses all throughout the year, depending what year it is?

  3. Dude I can’t even see lunar eclipse. South Wisconsin is a bad timer for eclipses.

    I’m thinking about moving to New York someday…

  4. moon: are u ready sun?
    sun: yes
    moon: ok iets go *moon covers the suns
    everyone: *cheering and screaming*
    sky: 🌑
    the end…

  5. 400 times bigger then the moon uhh that’s way off If you need over a million earths to make as big as the sun i think that the sun isn’t 400 times bigger

  6. Aaaaaawwwe i love this channel… I hope you're noticing all the comments i leave on your videos while i binge them

  7. I drove 400 miles in 2017 to see the American eclipse and I was not disappointed. I have to say it was the coolest thing I've ever seen. There's another one going through America in 2024 and after seeing one, I have to see it again.

  8. Are the suns rays parallel or not?
    You can’t have your cake and eat it, the solar eclipse in 2017 cast an umbra shadow 70 miles wide.

    The earth is flat and stationary 👍

  9. Imagine waiting an hour for a predicted total solar eclipse and then get cloudy,now you gotta wait another 100 years before you see another total solar eclipse

  10. I was so so happy to be able to see the August 2017 total eclipse. I believe I was in a place in the path where we got 80-85% totality but it was insanely cool.

  11. "The sun's DIAMETER is about 400 times larger than that of the moon and the sun is also about 400 times farther from Earth. So the sun and moon appear nearly the same size as seen from Earth". video just say sun is 400 times bigger then the moon

  12. Im so lucky i got to see the super blue blood moon then after a lunar eclipse uwu..

  13. I saw a lunar eclipse this past January. I'm 14. So I got tons of time to see a total solar eclipse

  14. Fake! The earth is flat you hear me! How much money did nasa pay you for this propaganda!

    ⚠️This is satire ⚠️

  15. Don't believe everything you hear…No mirrors were left on the moon period, Someone please tell me, what would happen if this earth was in an orbit 225,623-252,088 miles closer to our sun, or for that fact what would occur on this earth if we was 225,623-252,088 miles away from our earth's orbit from our sun? what will occur on our moon when it is 225,623-252,088 miles closer to our sun from our earth's orbit, light side or dark side, it doesn't matter, just look at our moon it will tell you!
    Average distance? Why mention the average distance? Well, the moon is not always the same distance away from Earth. The orbit is not a perfect circle. When the moon is the farthest away, it's 252,088 miles away. That's almost 32 Earths. When it's closest, the moon is 225,623 miles away. That's between 28 and 29 Earths. So far apart!

  16. WTF Is Vox actually trying to intentionally blind people. 1:05 "And a total solar eclipse is the only occasion you have to lay eyes on it…" Okay Vox very funny the punch line is coming, I am sure. 1:12 "This is called totality. and if you get to see it, you should…" (Looong pause from Vox, HAHA okay anytime now the punchline is coming) 1:16… Moves onto the next segmant without even mentioning that while the corona is the brightest and most damaging part of the sun you can look at it for longer during a solar eclipse because it isn't eye burningly bright like a normal sun so you can look at it without squinting (for longer also I believe) but it still causes damage at the same rate to your eyes and can lead to permanent blindness. Only 1:16 in so, I am sure Vox will put the punch line in at the end, HAHA, right guys? I hope you guys aren't the punch line.

  17. If the moon is moving away at a constant 3cm per year, then it was touching earth 12 billion years ago. Google says the moon is less than 5 billion years old. The rate at which the moon is moving from the earth must be variable, either slowing down or speeding up at some point?

  18. 0:04 0:05 NOTE that the shadow is BIGGER there in that example, but in real life that doesn't happen???? Anyone care to explain?

  19. This video was more informative than any other solar eclipse video I've watched, because i always get confused with why there aren't more lunar and solar eclipses.

  20. Omg this makes me mad I lived in the path of totality in 2017 and it freaking rained and clouds blocked it. All it did was get dark and weirdly animals were quite no noise and then it was light again

  21. the solar eclipce happens when the moon blocks and goes between the earth and sun a lunar eclipce happens when the earth is between the moon and sun an anular eclipce happens when the moon is fully blocing thesun but futher away

  22. On Tuesday, July 2, 2019, Chile and Argentina will experience a total solar eclipse at sunset.
    You can see the path of the moon's shadow here, and read more about the rare event: https://www.vox.com/science-and-health/2019/6/25/18715409/eclipse-solar-2019-chile-argentina-south-america-live-stream

  23. I saw the eclipse in the video as it passed through my home town, it was really cool, you should definately see one if you get the chance.

  24. Why are solar eclipses such a big deal? Well, obviously people need their broken hero swords smh

  25. I had a chance to witness a total solar eclipse but my tuition closed off all the windows so the students wont be distracted from class

  26. I’m from Argentina and I got to see a total eclipse today, it’s gotta be one of the most beautiful things I’ve ever seen!

  27. There has to be a creator of all this, it's not a coincidence that the moon and the sun appear to be of the same size on earth.
    So many planets and stars and nothing is on them, and on our planet thousands of species exists.
    A creator bigger than all his creation.

  28. If the moon move farther I cant see the totally only partial and the other one, I want to see the totally Im just a kid that love science and I only see the lunar eclips on January 31st last year, I live in the Philippines

  29. If we happen to be on Moon (or have a camera placed there) while there is a Lunar Eclipse on Earth, will it appear like a Solar Eclipse from the Moon?

  30. Great video. Thanks I learned that nodes are the two times the Moon and Earth are in perfect alignment with the Sun.

  31. I think this was two years ago….but I got a solar eclipse on my birthday. I was so excited….I never got to see totality because I wasn’t in a place were you could.

  32. We are experienced total solar eclipse often since few years. I thought it was very rare site. Even lunar eclipse were often seen since last year.
    Seems moon is entertaining us before moving away.

  33. Sorry you're Theory cannot be right because think about this how can you look up and see the sun and the Moon in the middle of the day now that you thought about that for a second stop and think about this the Earth is round we have been told it is like a basketball and we are told by scientists the sun is on one side during the day in the Moon is on the other side during the day but yet how come you can see both during the day how is it physically possible to be on one side of the earth and it be daytime and see the moon that is supposed to be on the other side makes you think the Earth can't be round circle ball

  34. Why do textbooks show the sun's rays hitting earth parallel when explaining seasons but converging when explaining eclipse?
    Why show path of shadow going east? Yes, moon revolves around earth same direction as earth rotates but earth rotates faster so moon appears to go west. The east coast sees the moon before the west coast. They showed the path of the Aug '17 eclipse going east on a stationary US map. The map should be moving, in effect, showing the shadow going west relative to point on earth's surface.
    Moon 2000 miles diameter gives a 70 mile umbra. So why then does earth's shadow cover the whole moon rather than
    280 miles?

  35. They are beautiful moments, shows us that there is a bigger world out there and that we are all on this planet together

  36. Oh wow WOW WOOOOOW the diamond ring effect wow that’s so amaizing 🌚🌚🌚….

    Looks just like a mad dream or a fantasy film land or virtual reality or a game or some other type of really cool simulation type thing oh wow wow wow that was so cool yaaaaaaaaaay 🤪🤪🤪🤪🤪🤪🤪🤪🤪🤪🌅
