Where Does Space Really Start?

[@Jbm510]

Alex, this is probably *one of your best videos* you have ever done! Beautiful, insightful, educational! I love it!

[@rolfw2336]

I didn't know the temperature varies so much in the different layers. Awesome presentation!

[@jasonvoorhees8545]

Look up the Coors Lite video where they sent the full beer can into "space" on a balloon with a GoPro and thermometer. You can see the temperature variations that happen on the way up. Very cool.

I plan on donating $50 this month. Your quality, presentation, oration, are all 9.5/10. Much respect from 🇨🇦 canada.

Why only 9.5?

Wait, $50 CDN or USD? 😅

$50 can so you are donating him $10 in real money?

[@blancaroca8786]

agreed absolutely superb... should be compulsory viewing for all school kids

[@paulkaye4924]

@@NoCumBacksiFunny seriously?! Lmao Do you think Canada is in Mexico? I haven't looked at DOW or NYSE in a long time but I'd guess it's about $40 US dollars! Decent donation imo for a video🤔 bahaha almost spit my beer out Anyway, cool YT name, I love the double entendre😄👍 it'd be a good 🎮 online tag for tea bagging lol Peace✌

I just found your videos and I subscribed. Needless to say, I've found a new channel to add to my regular favorites. :) So very nicely researched and presented.

[@astrumspace]

Hi subscribers, this is a reupload for a couple of reasons. Firstly, it was originally meant to be 4K but KZbin didn't render it at 4K quality, so I'm hoping with an increased bitrate it will work this time. Secondly, there were a couple of (minor) mistakes with the original which have now been rectified. I want this channel to be as high quality as possible so if there are some things I have done wrong I will always try to mend them and not to make similar mistakes in future! The original is still on the channel but is just unlisted for the time being. I will eventually take it down altogether. Thanks for the understanding!

[@nicholasveridiculity91]

'...if there are some things I have done wrong I will always try to mend them and not to make similar mistakes in future!' That simple goal would save the world, but for now, it'll produce high-quality science entertainment. Thanks, Astrum!

[@michaelcoulter1114]

Lol, you put out high-quality educational content, worry about making your videos perfect to the point where you edit a video to fix small mistakes, and you're thanking US? Nope. THANK YOU!!!

[@AZK303]

Thank you Alex for your videos. Clear, simple, truly educating and one of the calmest voices as commentary too. Truly great job. All the best.

[@blackmennewstyle]

It's mind-blowing to think that the actual temperature could be 2000 degrees celsius but because of the lack of gas particles, it will feel like below 0 degrees celsius, it's fascinating...

Beautifully produced documentary. Excellent research. I have been flying for over 10 years and have only for the first time witnessed Noctolucent clouds. Truly jaw dropping.

most interesting vid i've seen in a while, thanks!

[@conors4430]

Had no idea you could get clouds that Hi Up. Amazing. Also explained convection and the way it can cause storms and Hurricanes to spin in a way I understood for the first time in my life.

Very Nice video Alex . You may have mentioned the Karman Line that separates Atmosphere from space.

[@ArslanAfzal]

Love this video and really appreciate your efforts

[@thomspoody9887]

Very educational material presented in the most simplistic manner.

[@iam4740]

TBH, I listen to your vids before going to bed, due to the calming effect of your voice and tempo. The subjects are of interest as well.

[@jstrick38us]

Very good video! I haven't seen that much detail about the atmosphere since I studied it in grad school. I like your pacing and presentation and the images you find to go with your narration are great. The only criticism I have is that the aurora are caused by charged particles from the sun spiraling down the earth's magnetic field lines rather than by radiation from the sun interacting with particles in the atmosphere. I look forward to more of your videos!

[@eswing2153]

jstrick38us the cause is charged particles circulating in the magnetosphere but the light is from interactions with the particles in our thermosphere.

[@somnathganguly7253]

Beautiful presentation

[@Baldevi]

hank you for ths video, you have explained the Aptosphere so simply and easily, I really think I get it finally. I am an amateur Weather Enthusast too, so the names of the layers I know, but was unsure how high and what properties they had... now I can refer here to brush up!

[@ashclub1]

I take a bow. Wow! just loved it. Third eye opener...

[@zaugitude]

Thanks for the interesting and as always very informative video! A bit of additional info, the phenomena at 11:30 is know as irisation; it is very common at higher elevations even through the day. i see this many times a year living at about 8500 feet elevation.

[@dizz03y]

You, Sir, are a very good teacher / sharer of knowledge. Concise, clear, simple and very well articulated. Presented for easy absorption. Sincerity and humility are easily consumed. False pride and filler are not very palatable. Thank you.

[@josephvallejo2094]

this channel is so good

[@CrimsonHelldrake]

14:13 what about the ionosphere? that's nowhere on there? In my atlas it says that the ionosphere is above the stratosphere & it also lists a magnetosphere in there instead of exosphere.

[@Crowncity]

That’s on the planet Zoltar buddy. Wrong world.

[@alexolas1246]

the “ionosphere” seems to be another classification of altitudes, containing the thermosphere & parts of the meso- & exospheres. it’s defined as the bit where particles are ionized by solar radiation, whereas everything below it is called the “neutrosphere”. the “magnetosphere” arguably isn’t even part of the atmosphere at all, but part of earth’s magnetic field; it’s the zone where an astral body’s magnetic field affects charged particles. it extends to about 1/10 of the height of the exosphere, and apparently the ionosphere is just below it.

[@GTIngold]

​@alexolas1246 how's that magnetic protection work? Super heated metals are not magnetic. So that super heated core can not produce magnetism.

[@feelingzhakkaas]

indeed, i learned which i never learned before. Great work. God bless .

[@PeterArnold1969]

This is the first video I've watched on your channel, and I'm suitably impressed. I've learnt more in this short video than I did in my whole schooling.

[@metanumia]

Witnessing Nacreous clouds in-person would be like staring at a real-life Van Gogh painting in the sky, beautiful and bizarre!

[@stanleydenning]

Astrum: Thank you for this lesson. It filled in a lot of blanke for me.

[@jbtravels842]

Good information ℹ️

[@SeeMeRolling]

ive seen those noctilucent clouds several times and photographed them

[@honkyhanky2647]

This was my favorite clip on the subject, so far, and I have looked at quite a few. Good work. However, I do believe the ionosphere and the turbopause are overlooked. The latter is a very interesting subject, that few people are aware of.

[@astrumspace]

I was thinking of adding the ionosphere, but with the runtime of this video as long as it was already, I thought it deserves its own video in the future. Thanks for the feedback!

[@geekyoyd]

Superb video as usual. I never realised the layers were so distinct and related to temperature gradients. Also that the temperature dropped and then rose again! For myself as a middle aged viewer (54) who's mind never worked that fast anyway, I would like a little longer to view the stunning photos and diagrams alongside slower speech so I can take in one bit of information before you move on to the next.
