The science behind Earth's nocturnal light showClick here to SUBSCRIBE, it's FREE! -- bit.ly/iotbs_sub
Space might seem like an empty place, but the area surrounding Earth is constantly being bombarded by waves of charged particles released by the Sun: The solar wind. Luckily, thanks to Earth's swirling, molten core (and the magnetic field it provides), we are protected from this planet-sterilizing onslaught like an invisible force field
All that science has a beautiful side effect: It makes the auroras! The Northern and Southern lights are the result of the solar wind and its dance with Earth's magnetic field and polar atmosphere. It's Earth's own cosmic light show!

At 0:38 'Aurora Borealis' refers only to the lights in the northern hemisphere (from Boreas, or north wind); in the southern hemisphere, it is called 'Aurora Australis' (from Auster, or south wind). That's also how Australia got its name, meaning 'land of the south'.
Aurora Borealis?! At this time of year, at this time of day, in this part of the country, *localized entirely within your kitchen?!*
Ooooooo
I'm so glad you used Holst's Planets as a soundtrack.

During normal solar activity, auroras are limited to areas near the Arctic/Antarctic circle, and only in winter at each because of the constant summer daylight. But during CMEs of solar storms, auroras can reach much farther south, even as far as the Southern U.S. or into Australia.
i really wish these kinds of videos were on youtube before. But hell, I'm glad as it's here now. Thank you for making education enjoyable!
I think it's amazing to realize how many aleatory facts make our life on Earth possible. Think about it: No oxygen, no life. No water, no life; which means no hydrogen no life. No atmosphere, no life. No sun, no life. If the sun would be closer or further away... no life. If our universe would have no highs field, no magnetic field, no electric field, no gravitational field, or no nuclear force... you get it, right?
👍🏻👍🏻
God is truly amazing
Well things used to be very different for life in the earlier stages of earth. For example the first mass extinction was caused due to oxygen and most of life’s inability to intake it.
@@ericbeyer5121 God bless brother.
Yes, I get it. The Big Bang planned it all out LOL.
“The corona”
People in 2020: 😰
@『 YanaTriesToDOStuff 』 you extra it's just a emoji and you like: eWwWwW
I want to see the lights someday :) beautiful!
I too
Can I join with u?
Me too.
thank u for making this channel! i have learned so many new things! keep up the good work!
How many students came from Fea?😍
You have the best description. Thank you.
During extreme solar storms, auroras have been reported as far south as Mexico and Italy, maybe even beyond!
The sheets and "lines" you see in aurora shapes look that way because the magnetic particles are actually coming down into the atmosphere. You're sort of looking head on at them as they streak toward you.
There's a link to the Facebook page in the description! As well as my main blog on Tumblr, which is pretty cool if I do say so myself
I've never been anywhere you can see an aurora. thank you for bringing to me.
I didn't really understand most of what you said, but it sounds really amazing and beautiful. I would love to see Aurora some day
It also brought us trees and several different plant life. I got to witness this first hand in the winter of 2021/2022. 🥂❣🐞💚
2013 Its Ok To Be Smart:CORONA
Me in 2021:Bruh
These video keep getting better. :)
thank you for replying! you are doing a great job with the videos!
OH MY GOD GUSTAV HOLST IN THE BEGINNING THAT'S FREAKING AWESOME
Thanks for sharing this great video.
I love Auroras.
Imma put seeing an Aurora in my wish list.
Awesome show!!!
Thanks! Stay curious!
When did you start saying "Stay Curious" at the end of your videos?
Did he say it today Mr. Austin?
Nox Aghariya savage
Gorgeous and really informative.
Really amazing man! I love to see these kind of videos.
These videos are really nice :D
Found it! Wow, that is fascinating! Thanks so much for sharing. :)
The most intriguing part was about the telegram that was sent with the equipment unplugged. How could that possibly happen? Sounds so interesting.
But this is even better than TV, because you can watch it any time! Right?
Woooow amazing vid
Amazing.
I wonder what will happen or what we will see if we go into the auroras. Do anyone have any videos of people going into the auroras, I want to see...
Ohhh I like this channel. Glad I subscribed :D
I wasn't so sure at first. With this video, I'm sold. *subscribe*
really awesome
awesome video :-)
"Watching Aurora in REAL" is one of my "Before I die to-do-list". :-)
Thanks for the information.
thats one old comment
Cool! Science + history = awesome. A similar story came out last year that just blows my mind. Google "Red crucifix AD 774", Richard Lovett had a great article about it in Nature News.
I ♥️ Aura borealis it's so beautiful and i Remember watching a episode of little Einstein's and it was beautiful lol
Ya know, where was RUclips when I was in school? :-) I learn more now at 31 than I did my entire school years.
Discussion about auroras... *subscribes* looking forward to more space related videos! or just anything about science :)
You don't use together ''about and discussion''.
best explanation.....thank you
love it, best explanation ever
This channel is so great
This was beautiful.
This show is great, maybe sometime in the near future it will be on television? I would watch it everyday. Electric Space Kool-Aid
Great video! Keep 'em coming!
I just had an eyegasam!!!
GOOD LORD WHAT IS HAPPENING IN THERE?!
And thats no doubt really awesome
I thought you would mention cosmic Rays and Van Allen spots.
I'm a graphic designer - thanks for putting the official 'sky blue' hashtag code in!
Auroras happen in Montana (USA), not very frequently. But often enough.
Aurora,beautiful
Auroras are so beautiful its just like magic that there are real
You make awesome videos, I have subscribed and liked! =)
Perfect neat
SUPER Cool "invisible force field" neat
Exactly!
0:21 yup, we‘ve been here for one billion years😂
Amazing video
Didn’t he use to say „stay curious“ back then?😱
You're welcome! It's hard to do a perfect translation from real light to RGB, but it's close.
beautiful
cool, but why does it have those forms and those movements?
stay curious
yay.... new video
1:07 "The Corona"
???
done. my mind has already blown 🙈
Your mind blown just for this!!????? Bruh u wont make it what is coming next in facts
Boston to Portland unplugged.
Wow.
between minutephysics, teducation, vsauce, numberfile, scishow and now itsokaytobesmart I feel like I should be presented with a degree of some sort. I'll be waiting.
same here
Gustav Holst-Neptune. I thought I heard celesta.
nice vid
Because as the planet turns the atmosphere is in a chaotic motion with variations in pressure.
most of Canada, Alaska, Finland, Norway parts of Russia a bunch more look them up
Got to see one in elkhart Indiana Feb 16 2013 B-)B-)
great explanation. thank you
Aurora Franco cghjj
what countries, that aren't the the Arctic or Antartica, can you see auroras in?
C'mon, you should've played Jupiter, though I'm glad Holst's planets is getting some attention. From a musical direction standpoint Neptune and Mars work better for your show.
So it's like... Uncapping a neon tube, and shooting a current into the sky!
My grandma from Portugal once told me that she thought the world was ending, because the sky turned red. I decided to look this up and found out that what she witnessed was the result of a solar storm in 1938!
I meant that it's no big deal that it could power a telegraph station wirelessly when a tesla coil does the same. I didn't mean that the solar storm as a whole is no big deal-it is.
I think what's called for here is a food video. Specifically, what we associate as our favorite tastes. Vague, I know, but think of the freedom you have with your interpretation! I sound stupid right now.
Why does this video have less than 100k views?
Bonus points to anyone who can name that first song played in this.
Of course is better that TV, sadly there are no more edu channels on TV.
Wait wait wait. Wait.
If the multen core of earth is ultimately the reason why we have the Auras, then why does saturn & jupiter? As far I know they're GAS giants. Explain.
Ty Kenyon I'm waiting.
Great question!
1:09 the edge of the Sun is hence, infected
You can see auroras in Norway ;D
Solar winds: but this one goes all the way up to ELEVEN.
Neptune by Holst?
melody91179 YEAH!!?
Just fine! But what did you expect ;).
can we store that energy
Do a mathematics to science video if that is ok with you
I had no idea that Hilary Swank's deadpan was so perfect.
Gustav Holst.
