Have you ever wondered why the sky is blue? Neil deGrasse Tyson is here to help you answer that question alongside comic co-host Chuck Nice. And, you’re about to find out why the answer is easy to understand, but not that simple.
You’ll learn how the white light from the sun interacts with the atmosphere through a process called “Rayleigh scattering” that makes the sky blue. Neil tells us why the sky turns different shades as the day goes on, and why the sunset changes from blue to amber.
Discover why the reason we have a blue sky is the same reason you can’t see stars during the daytime. And, how this lead to the discovery of the operational definition of where the atmosphere ends and space begins. Neil explains why he thinks space should be defined by gravity and not by the circumstances of our atmosphere. Lastly, Neil gives us a lesson on the frailty of our atmosphere and our delicate place among the stars.

What about the purples and pinks ? Same concept ?
VIBGYOR is easier dhan ROYGBIV xD
Colour of Sun is white...Caucasians are Pink not White.There is no ground for racism .
Anything under our sun that doesn't contain air turns blue or is perceived blue through the eyes of a human N.b water reflects the colour of the sky
Ok so why do we see blue watching up but transperant looking to things closer. Like why isnt everything around me blue-ish? Maybe because there are less particals lower to the ground?
He definitely can’t repeat this theory, cause he making it up As he go
This dude is a complete JOKE and anybody who believes these fairytales are DOOMED
Who’s the guy interviewing ndt. He’s a legend.
If this guy was my teacher, I would go to school everyday.
I always wondered why we cant see planets during the day
I'm obsessed with this channel and I just found it LAST NIGHT! *StarTalk* is MY 'Space For Dummies'!🚀☄🌌🛰💞
Chuck is annoying
Science is Philosophy
Love watching you two!
Keep looking up, never know what you might see!!!
The evasive bicycle advisably repeat because separated advantageously multiply over a peaceful grandson. agreeable, deserted dolphin
So since the moon doesn't have an atmosphere, would we be able to see the stars in the day ? Yes yah ? According to this yah ? But how about mars ?
Joe Rogan needs to learn how to interrupt Neil deGrasse like this guy
I like to think that the different hues uh blue in the sky make up the different pigmentations of Krisna's skin. Either he can be a super bright pale blue, or a soopuh dark purpley blue like the night sky, and of course everthing inbetween ~ awsome to learn how stuff works and is made up of different energies! Thanks yall
Also thas a liquid shirt yo!
This guy is a fraud!!!
4.56
I love you guys!!!
This guy is annoying
Not anymore annoying than your presence
Love watching you two interact
This is the 9th explanation I've heard from the 9th different scientist.. Know one knows...
Because it was written that, the waters above from the waters below was divided by the firmament.. end of story
I love this
Then why does the sky scatter the light of the stars during the day and not at night
Proper color 😂
Neil deGreasse Tyson explains why my head is bald. (next episode)
Jokes and conversations of highly intelligent people are so amusing, no matter what they say it still sound conplicated but you kinda understand it 🤣
These videos would be 100x better without chuck.
Fun fact: the sky is blue did you know this???
I love it! chuck, when I asked that question (why is the sky blue) as a child I was told "because it's not green!"
The bromance is real😂
Why would anyone think he would know the answer to this question. The firmament separates the waters from earth and the water in heaven . What color is water 💧
Water doesn't have a color
@kenny walker I’ve seen water absorb and reflect light.
@jaymz1999 ocean water is not colorless and what large body of water have you seen that has no color ?
Water is colorless.
Man my brain was running from 0-200 watching this
Wikipedia him
Actor at his finest
Sure he's acting for the show but he knows what he's talking about he's not acting when it comes to science
it would've been easier explained if that other guy wasn't interrupting him
Because green is tacky
Missed opportunity. NEIL: “What’s the color of the sky at sunset?” Chuck: “ROY”
Very entertaining! Love this!
Love how Neil beats the learnin' into Chuck
Science is entertaining
These two are high
Man that shirt is out of this world
That guy is incapable of learning as soon as he brought race into it
“Cause I live in America” I’m done 😂
Why is water wet? Why did Judas rat to Romans while Jesus slept? WHAT!
the sky is blue because we live inside the eye of a blue-eyed giant named 'Macumber. ( Real G´s know what im talking about)
7:30-7:37 Chuck: (gets enlightened) Neil: YES!--- actually, no.
They both look so comfortable together
11:57 So that is what causes earthquakes.
Thanks for this! I'm a science teacher and had the privilege of naming our first-born daughter, Rayleigh. She's heard me say several times that I'm reminded of her whenever I look up at our beautiful blue skies and our equally majestic sunrises and sunsets. She now has a much better understanding and appreciation for why that is.
Actually it is not blue ... grand illusion ... we all know it, but we admire scientists who are trying to explain it. ;)
I love Neil deGrass Tyson also i just felt like Cleveland was explaining astronomy 👌🏼
The whole video is explained in less than a minute timestamp: 12:23
No offense to Chuck, but I just want to hear Neil talk
NDGT is soo amazing.
If my brain had pants, I'd need a new pair
Sometimes it appears invisible and we see darkness
Why the sky is blue?...because the earth is Flat...👍
Nah
😁😁👍👍
This is one of the most Lit science lesson I have ever had
Don't hit people when you talk ffs! nice explanation though.
so that explains it . But why ?
The video: why the sky is blue Me: ITS A BOY
@ẞ45h[ ] r Yeah lol
I can imagine the next gender reveal party results in the entire planet exploding and the explosion colors blue or pink congratulations it's a boy with the Earth exploded into pieces
He is just lying,the sky is blue because of the water above,smooth talk no truth
Nope that's not how gravity works
From the waters above....Man lies Bible don't!!!!
You put all your trust into a book that you don't even know where it's origins come from the original story lost in history there are only modified versions of it don't believe everything you read
We're ingaged in a war isn't that right
imagine if he told you there is no color just wavelenghts converted into electronic signals and colors is just a construct of your racist brain? just so happens that most people have the same kind of racist brains regarding to colors. But than there are those who have a diffrent bias and we call them color blind? allthough they perceive colors just diffrently. humans are just so pathetic in comparison to physics.
I've learnt more from Neil than any teacher from school.
The sky is blue because it’s Water, read the Bible
Okay but what if it's false then you would be very wrong not to mention that's not how gravity works
Why is the sky blue? Because Tyson broke a globe and bopped Nice on the head with it.
The sky is a hue of indigo that no human can see. Every sunset on a clear day is a rainbow.
Could you imagine smoking a j with him wow
This guy have a 5th level entellect, and he is enjoying it.
So many ppl legitimately think it's blue from reflection of the ocean 😆
That "because I live in america" had me dead 🤣🤣🤣
Why the sky in china always gray
Because a lot of people live there and there's a lot of pollution because Earth is overpopulated with the form to mental idiots that don't understand when enough is enough that want more that ruin the environment for their own intent for corruption and entertainment humans are an invasive species for the entire planet I hate us for that
If Neil's definition of what is space is true, does that mean the moon wouldn't be in space, coz it's in our gravitational field, in orbit
What do you mean
I was said my boys list to the Indians. I don't change my mind.
The best “insult” ever: you’re such an astrophysicist 😂❤️
I love how this is such a kindergarten explanation. I guess the saying is true, you can't really understand something until you can explain it to a 5 year old
Its obviously trumps fault and he needs to be arrested for it.
And why is the SEA blue?

Amazing!! 🤯
Chuck, I caught that: You thought it was ROY G BUV with Ultra-Violet at the end. Don’t lie 😂
English version of the question would be ‘why is the sky grey’
Only blacks can goof about racism. If white people do, they are called racist by the libtards.
I know I ain't the only one who thought of one piece when he said Rayleigh
So it aint the ocean😢😭
The ocean looks blue because the sky is blue.
Astro Klump is awesome!
So what's happening to the Red or non-blue component of the white light during the day. As Blue is scattered intensely during Sun sets or rises, Red light becomes predominant. Now we see red component? Why not during the day if sun light is lit directly during the day?
