You have to love how many beautiful things on this planet either represent or will be your doom. From the great prominent colors and patterns on poisonous animals to how it is said that the sight of the reactor breech at Chernobyl was apparently quite the sight from a good distance away (not entirely sure about the veracity of that, but it gets the point across).
Radiation makes a nice blue glow so it was probably true
@@MrNinjaman63 Hello, greetings from Canada 🇨🇦. How are you doing today?
Liquid Oxygen is the prettiest blue color. You'd think it was the newest Gatorade flavor if it wasn't boiling violently at room temperature and frosting everything it touched.
Chernobyl's blue glow would have absolutely been a lovely thing to behold...
I've seen a couple videos right here on youtube that show the light of ionizing radiation through the cooling tanks of reactors as they power up.
If that were visible in a nighttime sky, it'd be truly beautiful!
@@willhouse A lot more than blue when talking about Chernobyl. I am not talking Cherenkov radiation. Or at least not just Cherenkov radiation, I think it had to do with radioluminescence in general.
Yes have seen Noctilucent Clouds quite a few times here from Northern Denmark (56.9N). They are incredibly beautiful with their clear blue color. It is the same color you see at the cathode in an old transmitter tube made of glass.
lmao, you talk about northern Denmark as if it is a real place
@@curiodyssey3867 it is... Skagen is beautiful and the way (by bike/car) up there is a strange one (usually i get impressions of "moon-like" featured dunes..) - it's a halfworld/Halbwelt feeling between East- and Westcoast and i recommend visiting it^^
It’s the same in northern Canada.
Color ‘sky’
Color = blue + clear
@@Dr_Larken clear is my favorite color
I have been a "weather nut" and cloud fancier since I was little in the 60's. I am always watching the clouds. Something I have noticed a change in is the cirrus clouds (the high wispy white horsetail ones). They were always white. ALWAYS! Now, some are becoming blue/gray like rain clouds (nimbostratus). I can only conjecture that as the atmosphere warms up, more moisture is being held at higher levels. See if you are noticing this also, especially during storm fronts. And , yes, I have seen the noctilucent too.
Do you think thats a bad thing?😟
Geoengineering has been going on or many years , worldwide
@@crystaldreams3978 I think it is just that as the atmosphere heats up at higher levels it can hold moisture where it didn't before. This allows for heavier downfall of rain, hail, etc.
@@jajphotog77 oh ok. Thank you🙂.
I saw them too those dirty clouds. White and Grey, like Rain and simple said I think the Grey comes from the chemtrails. Just like the sea is full of plastic the Air is full of chemo. How long are we staying stupid?
The notion that the warmer the climate, the colder the mesosphere gets is such an amazing thing.
Afaik this wouldnt be the only place that cools down, there is another layer in the athmosphere (forgot which) which also gets colder due to the greenhouse gases below not letting as many infrared radiation through as normally
@@DreckbobBratpfanne the stratosphere cools down as well. And the possible formation of polar stratospheric clouds in such a cold stratosphere is theorized to be one of the reasons the poles were so incredibly warm during greenhouse periods.
It’s because the troposphere is retaining more of the heat that used to heat upper air layers. CO2 retains heat, that’s what it means to be a GHG greenhouse gas.
I guess, it pretty much seems in line with how nature tends to work. Humans are the ones oversimplifying things with their arbitrary labels and assumptions of direct causation. Often if you push something too far in one direction it catastrophically swings back around when dealing with physics
I remember seeing the 2014 Noctilucent Cloud made by the SpaceX launch while biking to my high school in Tampa Bay. It was roughly 5 or 6 in the morning, the sun hadn't truly risen yet, and you could see the cloud spreading from the tiny exhaust plume of the rising Falcon 9. There was quite a bit of talk about aliens
Not quite the same thing, what you saw is called “twilight phenomenon” created by the exhaust plume of the rocket. Noctilucent clouds are water vapor clouds high in the atmosphere, although some rockets can reinforce noctilucent clouds if they use hydrolox due to water vapor being a component of its exhaust.
👽🛸
Dude i saw that too. I had no idea about the launch so i thought i was witnessing some crazy phenomenon lol
Happened to me once last year at 5 in the morning in NC before swim
Practice. It looked like a bright flashlight pointed at us with a cone of light spreading behind it, we thought it was aliens
Time to investigate spacex for crimes against humanity then hehe
I used to see these clouds quite frequently in summer, when I lived in the North of Cumbria, close to the Scottish border.
The window of my study, where I spent most evenings on my PC, faced North, was on the second floor, and the house was on the edge of a ridge so I had a full view of the Northern horizon. In the summer months, the Sun doesn't dip far below the horizon so when Noctilucent Clouds are present, they're visible all night.
Unfortunately, I don't get to see them any more - I live in Brazil now. Have to make do with the sunsets instead.
Y tf did u move to brazil dawg 💀
he took you're going to brazil too serious
@@great_channel The quality of life here is far better than anywhere in the UK. There are many things I miss but overall, no comparison.
@@jakelavaclaw2759
The first time I came here was to see my cousin, who'd moved here 6 years earlier. He was married to a Brazillian and had two kids.
I spent 1 week at my cousin's house (set in a large garden with a barbecue area and a pool) and 1 week at my uncle's house, by a river, in a town 25 minutes drive from here.
I loved the place, as they all did!
My cousin offered me work so soon after going back home, I sold everyhting and moved out here. That was 13 years ago.
I have zero regrets!
The Uk is a great place to visit - not such a great place to live.
@@antonystringfellow5152 the new world is where it's at man
I actually saw them over Indonesia. I was flying out and when the plane reached cruising speed, I looked up and saw these thin wispy clouds so high up I felt like the plane is still on the ground. I was surprised and I thought we are already higher than the highest clouds.
I thought you can only see them in the northern and southern hemisphere, 50° to 70° no?
@@uyagraph you'll see them more often at higher latitudes because NLCs require very cold conditions to form. In rare occasions, the mesosphere at equatorial latitudes can equally as cold too.
@@ChuDust I can't say I've ever heard of noctilucent clouds forming at equatorial latitudes before! Furthest south I've known them to be is Italy (and probably only northern Italy). Maybe they were manmade noctilucent clouds from a rocket that monosodiumglutemate8216 saw...
Visible pre-sunrise too, not just post-sunset. I saw noctilucent clouds one summer morning before sunrise north of Toronto. My first thought was that it looked like frozen lightning; it was dominated by such incredibly bright blue-white streaks. By the time I got my camera and tripod out they had faded somewhat, but still made for a spectacular photo. The contrast with dark sky above and early pre-dawn sunrise gradient on the horizon highlights their strangeness. Thanks for the details!
technically pre-sunrise is post-sunset still.
Is there any way we can see the photo you took :0
These clouds remind me of a sight I have seen on rare occasions growing up in Southern California. Being close enough to Vandenberg military base and launch site to actually see rockets flying through the sky (from OC, CA, I have seen the actual rocket with flames pouring out with my naked eye, one of the most incredible sites of my life, watching the broadcast online and running outside to see it reveal above my roofline). I've only seen a rocket once, a Space X rocket. It was incredible witnessing the moment it broke through the atmosphere and watching the first stage break away and head back down. I will never forget it and writing about this, I'm getting motivated to travel north to see it again from much closer.
These launches occur often enough during twilight, 30 to 1 hour after sundown. It's incredibly beautiful to see the smoke left behind from the rocket. You see swirly clouds that look very similar to the noctilucent clouds, that reach all the way to the upper portion of the atmosphere where the sun is still hitting, illuminating the clouds. You can literally follow the clouds to the point where the rocket enters space as the swirly clouds begin to take on a symmetrical cone shape in the absence of gravity and wind. It is truly incredible and absolutely gorgeous to witness.
I'm in central Florida, about 90 miles NW from the Cape, and have witnessed many such launches over 6 decades... that said, the SpaceX launches are the most spectacular! Saw one last month, clear dark skies, saw the re-entry burn, 2nd stage burning to the NE, the "jellyfish" morphing, and all!
Last year, one (IDR whice one) launched Southeast, directly away from my location. I counted down the seconds as I watched it fade away, and around the appropriate time the low rumble of the engines pointing directly towards my location as it pitched downrange could be heard! It was the first one I'd heard since the last Saturn V mission.
It's getting busier, enjoy the shows!

@@JustinBradleyPhotographer Its massive. Tell me again about all the rockets you saw but then only saw one.
@@sproctor1958 It's a great time to be a photographer. I know it's been done before but I definitely want to get one of those long exposures tracing the entire flight from ground to atmosphere. As a space nerd, it's a very exciting time to be alive.
@@JustinBradleyPhotographer I've gotten some excellent shots with just my Samsung cell phone... on a tripod for stability at that distance. Mostly stills, I can't remember about taking video...
Also done a little astrophotography that way with good results!
Funny, I’d just seen Noctilucent clouds few days ago. I’ve seen them before, even took quite a nice picture several years back. Will try to photograph them again in the next days and weeks. They’re truly mesmerizing, otherworldly, and awe-inspiring creations of this universe!
NASA's first priority when naming a spacecraft or piece of equipment is that the name forms a cool sounding acronym.
yes
Same! I saw a bunch of them yesterday evening
I used to work outside on night shift and saw this quite frequently. It truly is a special thing to witness. Thanks for the video to do this justice :)
Scientisms: How do i link phenomena with the lucrative Climate Change Alarmism industry?
You're completely delusional if you think climate science is a lucrative career
@@thomasneal9291 Trillion dollar industry. Hundreds of billions transferred already. You are too ignorant to be forming opinions let alone posting them.
What kind of job did you do outside on a night shift if you don't mind me asking?
@@TheBelrick You have no idea how research works do you?
They look like slight wind rippling the water over white sand. Etherially beautiful.
The past 24-36 months have also been a particularly active volcano period. While few have been threatening well habited places, we have seen some fairly high discharge events, such as HungaTonga.
Oh?
@@larniieplayz6285 yeah, hunga Tonga was the biggest volcanic blast in the last 30 years
@TheManFromAuntie Pole shifts happen gradually over geological timespans, they don't reach a critical mass and then instantly switch places.
After periods of extreme tectonic activity, as the plates cool, the magnetite and other iron sources in the plates slightly magnetize along the lines of Earth's current magnetosphere, and then harden in that alignment and stay that way. In the 1950s, geologists started finding rock samples with iron patterning that indicates Earth had a different magnetosphere orientation when they cooled than the one that exists today. This is how we discovered the fact that the poles move in the first place.
Using this technique, we can go back ~160 million years in Earth's geological history and deduce the orientation of Earth's magnetosphere at the time the rock cooled, at any point in history along that line. And what the geological records show is that for 160 million years, the poles have always moved gradually, never instantly "flipping" and causing some huge natural disaster. The rate of change *does* vary, but not to the degree you're talking about. All pole reversals in the past that we have evidence for happened over 2,000-12,000 years. In fact, the movement of the magnetic north pole has slowed down the past few years.
There might be a cataclysm in 2023, but it won't be that.
I’ve seen this once, in The Netherlands. I was driving my car and was struck by the sight. I had no idea what I was looking at but knew it was special. Luckily I had my camera with me so I parked and photographed the phenomenon. Quite breathtaking - more so now that I realize I might have been looking at cosmic dust :)

Garrett for Nile, Kelly but who's Alex? From animalogic?
Not to gainsay you, but - from my experience in the US navy - noctilucent clouds can also be seen in the predawn hours for the same reason as they become visible after sunset. On very rare occasions, they can be seen during normal daylight hours at higher latitudes such as in the Bering Sea and near Nares Straight off Greendland, but this requires nearly perfect visibility conditions.
I’ve seen it 2 times in my life up in Minnesota and Wisconsin. So breath taking and wonderful to see. Best I can describe it is like seeing glowing Clouds in the night time.
At a quick glance, the first image looked a lot like a snow covered mountain! Was absolutely beautiful!!
Hello, greetings from Canada 🇨🇦. How are you doing today?
I live in Denmark. The sun is about 11 degrees below the horizon in the middle of the night this time of the year. So I sometimes see these clouds. Great to know the science behind them.
I'm in western Washington, and I feel like I've seen silky, glowing clouds in the evening a handful of times. My favorite odd atmospheric quirk around here I learned about from my friend's dad, who was ex-navy, is that on certain days when the atmosphere is just right, it can bend the light between us and Hawaii, making Hawaii visible to us as what looked like an extra, pale mountain range behind the mountains we're familiar with seeing. That was in Edmonds.
I’ve seen noctilucent clouds once, shaped like an octopus and that was Yakima, 2008, haven’t seen it since. Obviously it was from a meteor.
@@memyselfandi8544 That's around the time I moved from Edmonds to Olympia, and makes me wonder if that's what I'm recalling... At any rate, thanks for confirming that such phenomena has, indeed, happened around here! I hear the night sky is gorgeous out in Yakima.
By the way, I love how noctilucent clouds act just like tropospheric clouds, forming lacunosus holes, undulatus ripples and radiatus strands. Would be cool to find out more about how the winds act up there, as wind shear typically forms undulatus down here in the troposphere, and radiatus clouds form parallel to the wind (which we can see at 1:07 in this video). :D
Gorgeous footage. I live much too far south for seeing these (I'm in southeastern US) but twilight is absolutely the most magical and beautiful time of day... I well recall actually seeing the Earth's terminator line above my head one fine evening, when conditions were exceptionally clear and juuust right - my friend and I stood there and stared for many, many minutes. That phenomenon, like these clouds, remind me of that bit in Disney's "Fantasia" film, during the Beethoven piece, when Nox is drawing her cloak over the earth - that strange and veil like formation and the almost mystical feeling of seeing something you can't quite fully understand. One of those times where, even when you know the science, our planet's beauty inspires us to poetry in every century.
Thank you for such a wonderful video!
Thank you, Alex. As always your videos are very well thought out and put together.
I saw these clouds once from northern Maine (about 47 degrees N), but they weren't nearly the same as the ones shown here- just a couple of ribbon-like clouds. This video may also serve as a warning from the Earth to be careful with its atmosphere. It may seem almost limitless to those of us on the surface, but when seen from space, it's a very thin layer!
@@rajeshupadhyay5683 Can you explain how your comment relates to mine or, for that matter, the subject of this video?
Seriously, people- be honest. Are you all spamming here? Your comments in response to my original one are not related at all, nor are they to the subject of this video.
Never mind- I've just reported all your channels (it may really be just one) for spam.
I also reported the unwanted spam content. 👍🏻
Now back to the video content and response to your comment ....
Do you think it's possible the high number of telecom satellites could be causing the cloud anomaly due to the attenuation of the comms transfer beam?
It's just that a professor at University of South Australia called Silvia Covacio was concerned about the use of so many satellites and the radiation could affect the atmosphere. 🤔
@@fractaldreams1822 To be honest, I'm not sure. I was only able to find one result for that name on Google, and the entry had nothing to do with satellites.
Another search indicated that these clouds were first noted in 1885, after the eruption of Krakatoa.
But I'm not very well-versed in the subject, so I really can't say for sure.
I live 54* north in Alberta, Canada and i'm lucky to see these a handful of times (if i stay up late enough) every summer
Hello, greetings from Canada 🇨🇦. How are you doing today?
I think I may have seen them once while working in fort mcmurray, wish I had known about them back then I would've paid more attention
Hi, I saw my first Noctilucent clouds early this morning, it was very beautiful. I live in Yorkshire in the U.K. and I was driving home from work between midnight and 2.30 am. There was a one very long thin thread of light, that looked like the sky had been cut open and later tendrils of light that seem to move. It expanded and filled a single area in the Northern sky. It was an awesome sight.
I went to music festivals in the summer months for 12 years. Often saw clouds like this in the morning. The brightening sky was my cue to get ready for bed, and sometimes I'd watch the horizon for a little while, and was gifted by many sightings. I didn't know they were so elusive and special. Lol
I saw these the other night and it was amazing. Bright summer nights in Sweden is a bliss.
I only clicked on this from mild curiosity. What amazes most is the narrator explaining this so clearly. He really did a good job.
Talk about synchronicity! I saw some last night/this morning, around midnight - couple of trails of cloud with an eerie glow to them. There were just two of them, high in the sky, looking like waves washing up on a beach.
Startled me a tad! Did think of trying to get some pictures, but I don't have a camera that can shoot at night. I could only gaze in wonder and a bit of awe at what caused them. Now I get the chance to find out! so thank you for the vid and for the timing.
ps I'll have to look again tonight, just in case
[I[m in Shropshire, UK]
I saw this in 2008 over my Ruapehu in the central volcanic plateau in New Zealand. Only 37S.
It was a few hour before dawn in midwinter from Mt Ngongotaha nearly 200km away.
They looked like an inverted image of the mountain. After less than a minute they dissolved and evaporated.
Electric and magnetic phenomena are involved.
They are becoming more common as the Earth's magnetic field weakens and destabilises, allowing magnetic flux pipes to connect with the sun's magnetic field and channel charged particles in spiralling along the field lines.
When I saw them, obviously Ruapehu, a tall stratovolcano was creating an ionic wind and updraft from its warm crater lake. The mantle is positively charged, the crust negative, and the proton belt from 600 km up traps enormous positive charge.
Phenomena like this are more common than you think.
I didn't even know these existed until now. Very interesting.
I’ve seen Noctilucent Clouds quite a few times, didn’t realise they were particularly special 😅 I live in southern Norway 🇳🇴
Sorry. I missed the part of the video which explains the reason why the scientist are worried. Did anyone else get that?
Thank you in advance :)
Love your videos Alex! Keep up the good work.
I was waiting for it too
clickbait added to alter the original video title
Noctilucent clouds form when warm air from the lower atmosphere is rising up.
More frequent noctilucent clouds mean that the atmosphere is heating up, i.e. another effect of climate change.
Which _is_ something to worry about, so the clickbaity title makes at least some sense.
@@jamesengland7461 Hello, greetings from Canada 🇨🇦. How are you doing today?
Explanation at 8:55.
I was just talking about this video yesterday. I was walking in the park and saw iridescent clouds floating in disk shapes above big fluffy clouds. I came to learn that these were "fire rainbows" or circumhorizontal arc formed by light hitting ice crystals in a cirrus cloud. I've never seen this before in my life, and apparently they're rare. We're on day 3 of a 5 day heat wave and lost power at one point, but floating up there are tons of ice crystals being hit by the sunlight and making the clouds look magical. That's when I remembered this video. Haha
I spent most of my life in Montana and saw these a few different times when I'd go out camping or stargazing. Really beautiful sight, had no idea there was a specific term for them or that they were so rare. I figured they were just regular clouds catching the last bit of light from over the horizon.
Where in Montana? Just a fellow Montanan asking...
@@brandoninhofer6592 Twice that I can remember up in Glacier, and another time at Browns Lake. The stargazing was particularly good at Browns Lake, but that was the least impressive of the times I saw these clouds.
@@ledumpsterfire6474 Yeah I've seen the stars up in Glacier, it's really amazing.
Wow! These look very similar to the condensation trails that fill the daylight sky’s. It is interesting how the con-trails spread out over vast areas and form clouds. These clouds that develop after the con-trails spread out, look eerily similar to these strange clouds.
*chemtrails
Great to have a cross-over video between astronomy and meteorology! I've seen noctilucent clouds quite a few times after sunset. They can sometimes be quite beautiful. Mum told me they were called noctilucent when I was at school in the 1980s!
Today's beautiful sight was another halo around the sun with colours in it - a hint of red-orange-yellow.
Your Mum was very well informed, pre internet.

Congratulations of hitting over 1mill bro! Keep up the hard work and continue these amazing contents!
once seen a jet contrail that behaved like a Noctilucent Cloud - being well lit in the very early dawn whilst still pretty dark at ground level
I live in Stockholm and I have taken many images of them 😊
Btw! At 04:10 there is an image of what looks like a comet seen through the noctilucent layer of clouds
likely C/2020 F3 NEOWISE.

So cool.

Thanks for verifying what I noticed too...must've been quite a sight in person!
Huh… why yes it does indeed
Oh, I totally missed it...thanks!
We did just have a massive volcanic eruption in the Pacific. Quite a lot of debris launched into the atmosphere.
I’m curious if there is any chance of similar clouds forming in the lower layers of atmosphere. I understand your explanation of how they “glow”, needing extreme cold temps, dust and ice particles….but I have been witnessing “glowing” clouds after dark, amongst very dark clouds in an otherwise dark sky (hours after sunset).
Though they aren’t usually thin ripples, they are often times closer to an average cloud, only without clearly defined borders usually; sometimes long and drawn out, more hazy almost like a painting.
They are breathtaking & beautiful, but at the same time a bit unnerving as I’ve only more recently noticed these-my imagination gets the best of me and ends up inside an episode of X-Files lol.
I live in Western Washington State, the (Pacific) Northwest corner of the US, near the water. The clouds truly do look like they are emitting their own light, like Phosphorescent.
Is it at all possible this leftover sunlight could also illuminate clouds in the atmospheric layers closer to the ground/sea level? I do live smack-dab in the middle of a major convergent zone, if that has any impact.
Very interesting, thank you for your video!
we have polluted our beautiful skies
What you are explaining sounds like light polution from population centres. It's all the outdoor lights illuminating the clouds.
I could be wrong though and you are trying to explain something else entirely.
I took pictures of Noctilucent clouds last night. It was a clear sky and a full moon, and as I was watching the moon, I noticed these odd clouds coming in, and started taking pics on my phone. Wish it was a better camera. They came drifting in over and around the moon, and the moon developed a pink hallo around it, for the better part of the whole formation passing over. I'm an avid sky watcher and knew they were unique, like a few I'd seen before and thought it was these particular clouds. This video verified it for me. Thanks 🙏👍💜
I've seen them truly a sight to behold like looking up underwater and seeing the surface of the water from below
I have noticed a big change in clouds past 7-8 years . All sorts rainbows in sky and more . I by habit read clouds and weather as a sailor
Fascinating. I was wondering about those clouds. Having seen them for the first time recently. Questions answered! Thanks!
I saw them here in Texas. There was an aircraft leaving a contrail at about 1:30 in the morning as I walked home. About an hour later the contrail had expanded and there was a rift as bright as daylight
Did I miss the part where it's explained why this type of cloud is worrying scientists?
No it was clickbait.
Just another climate change scare video.
Disregard.
Thank you so much for raising the bar on such important conversations about our world. Very inspiring, indeed. Well done.
Wouldn't a fair chunk of the dust in the Mesosphere have come from the Hunga Tonga volcano? I seem to recall the ash plume from that volcano actually reached the Mesosphere although I'd imagine the quantity of Ash particulates would've been very small if that were the case.
these clouds often appear over moscow, especially at 2 to 3 am. they're really stunning
I wonder if earth's noctilucent clouds may be similar to the tenuous clouds seen in Mars' atmosphere?
Wonderful, fascinating video. Thank you, Alex.
Dust that high up is even easier to explain on Mars with it's lower gravity, but the ice crystals would have to be something other than water
I got a beautiful picture of on of these early in the morning a few years ago in Salt Lake City, and used to see them several times during the summer months in northwest Montana. The first time I saw them I thought I might be catching the tail end of the auroras it was so strange looking
North coast of Ohio, yes have seen them several times...surreal and enchantingly beautiful...yet they cause pause for one, you can't help but feel like you're seeing into a hidden facet of our planet!!! Great topic and video, thank you yet again!!
Ohio has a coast line?
@@michaelross1452 With Lake Erie.
@@michaelross1452 Hello, greetings from Canada 🇨🇦. How are you doing today?
I'm on Ohio's northern coast too, about half a mile from the lake, and I've seen them a couple of times. Bizarre and absolutely beautiful. It looked like the sky was opening up, lit from behind. It reminded me of sunlight on water. I did a search and figured out what they were, but I didn't realize they were so high up. Hope to see some this summer. I plan to have my camera on clear nights just in case.
I grew up in southern Nevada in the early 60s. I saw these types of clouds on three occasions, and I just assumed they were associated with experiments at the test site. It was sort of vaporous, but looked like a river flowing in the sky.
I have seen Noctilucent clouds many times, without knowing what they were other than extremely high clouds. they are especially visible during summer, when, from where I am, I can see the glow of the daylight from the north without it being too intrusive on our night time. this makes noctilucent clouds easy to see when they happen, but from my position they appear more orange than blue but I can see the bluish hues as well. Huh, had no idea how they formed or how high they were. I thought they were at the Stratosphere, but they are even higher! Wow! Cool, thanks for sharing!
Every day, for the last year, we’ve had scenic clouds roaring over. The weather that comes after. God damn.
I have seen these in the Stockholm arcipelago during the summer. Always wondered what they were!
I saw some clouds when I was in Kansas that looked like waves in the ocean in the sky. It was amazing
Funny enough, I have never seen noctilucent clouds.
Until I went out to take pictures of Comet NEOWISE C/2020 F3. At first I was annoyed about the thin cloud cover, obstructing my view. Only afterwards I realized what I have seen for the first time!
My view was basically this scene: 04:10
Oddly enough it was yesterday on my way to work 3:30 am (6/21/22) Spokane WA. While the rest of the sky was dark except for a hint of sunrise, to the north were these beautiful glowing streaks of pale blue. Now I know what I was seeing.
Thanks, Alex for the video. My theory is that the droplets of water are coming from space. Scattered particles of O2 and H2 coming from space and the sun can recombine in the ionosphere. Also, let's remember that the mesosphere is cooled down by CO2. Another point to note is that the troposphere is not warming up. We are getting more and more snowfall. Here in Vancouver, we had the coldest winter with temperatures going down to -18˚C. Although in other parts of the planet it's warming up, globally it's not.
I saw this with friends up in Michigan back in 2015. We had no idea what it was. My best guess was that we had somehow seen the northern lights somehow, but that's way to far south still. I can't believe I finally know what it was! I feel luckier than I did when I saw a meteor crashing through the sky! It was such a beautiful event, the best way I can describe it is as white sky fire.
Scotland was covered in them for five days this last week over Xmas ,huge .I videoed them,
Awesome channel with awesome content and great quality as always say 🌏💯
Could air travel technology have anything to do with the unknown particles in the mesosphere?
One of my hobbies is photographing sunsets, living on a small island I get some amazing sunsets from the beach these clouds can sometimes fill the upper frame of the entire picture its amazing to watch
I’ve seen noctilucent clouds from my home in Northern England 53.5°N during astronomical twilight in summertime. They are very beautiful, and thanks for mentioning one of my favourite stars ‘Capella’.
I first saw noctilucent clouds in the UK in around 2013 coming back from a job late at night, could have stared at them for hours. I always go out around June/July nights looking for them.
I saw them the same year in Devon. Always wondered what caused them...
*No one is discussing WHAT HAPPENS when the moisture forming the clouds, accumulates so much it affects the amount of Sunlight reaching the Earths surface !*
Hi Alex, love your videos, keep making good stuff like this!🔥♥️
Shockingly I have seen them! Really trippy filaments that almost seemed iridescent that stretched from one side of the sky to the other. We had no idea what they were. But we all felt awe!
I was studying in Durango CO back in 2017. I remember on halloween (of all days) seeing what was most likely one of these a few minutes after sunset. It was like aurora, but a full rainbow of technicolor. It definitely dispersed like a cloud would too, but was crazy bright. I showed my astronomy professor a picture I took of it the morning after, and he was so baffled he did a double take. Neither of us had any idea what to make of it. I also saw a good deal of meteorites in the area, both during the day and night of that month. That space dust hypothesis sounds about right, at least in this context. Otherwise, I would have been at too low a latitude.
That sounds incredible.
The colours you describe do sound very like the aurora borealis, it can have a lot of greens and violets.
@@eh1702 We considered that, but it was a full rainbow of colors; Green, blue, violet, red yellow, and most telling, some white too. I still can't say for sure, but the pictures I looked up from this video seem a bit more in line with Noctilucent Clouds.
@@MrThatguyuknow Hello, greetings from Canada 🇨🇦. How are you doing today?
It's helpful to remember that the largest and tallest thunderhead clouds - Cumulonimbus, can reach into the Tropopause, at 50,000ft or 15,000m. Cirrus clouds are the highest you would normally expect to see, at altitudes of up to 20,000m or 66,000ft.
I absolutely love when we can see then up here in Sweden! I never saw them while living in Southern California. There isn’t any other cloud formations that are as beautiful as these Noctilucent Clouds. And I’m thankful that I do get to see them year after year. 🤩😍 Thanks Alex for doing this phenomenon. It lyes close to my heart.
I live in San Diego and was lucky enough to witness the noctilucent cloud produced from the SpaceX launch in 2018. It was quite a sight and I hope to see something like that again in my lifetime
We have seen these clouds in some rare occasions from places in northern Germany and Denmark. They are unbelieveble beautifull.
Beautiful,, Thank you for sharing
This combined with the extinction of other cloud types and the changing size of rain drops is indeed worrying.
Title: why these clouds are worrying scientists
Conclusion: that's all there is that you'd want to know about those clouds
Me: clickbait, also video is 1 minute and a half longer than 10 minutes so he is able to get more money, how convenient
When we went to the metropolitan museum in NY. I happened to be looking at old paintings and saw this type of cloud formations.
Absolutely love your videos! Thank you for them all!
Hello, greetings from Canada 🇨🇦. How are you doing today?
Yes, I live at 60,6N in southern Norway and I've seen NLC the last 4 summers. Usually in July, with clear skies to the north. Sometimes at sunset I can tell if the conditions are right already then, because there's a "glassy" transparency near the horizon, but it takes high pressure weather.
Addition: One reason I didn't see the NLC so often before was living in a city..
clickbait title, nothing was ever said about "worrying scientists". first time I've ever seen one of this channel's video clickbait a title like this, hope its not gonna become a trend.
I must have dozed off during the part where you explained how the clouds were worrying scientists.
These "clouds" are pretty much everyday in the CA Bay Area. These are created after an ionized layer of geo-engineered particulate is released, held up by surfactants to suspend it while HAARP hits them (how the undulation effect happens). Explains how the clouds move while the undulations stay the same
Your summary is more likely than the romaticized views of the rest.I believe in time these ionised geoingeneered atmospheres will eventually turn the moon and sun dark?
@@crockadial6343 That’s the plan, and that’s what’s already happening. F*cktard world can’t put two and two together and don’t question why the entire world is all of a sudden completely coming down the past 2+ years. All of a sudden, there are record wildfires happening all at once. All of a sudden, Southern California experiences complete “cloud” cover where there is no visible sun, no visible sky…only this weird completely uniform gray ceiling of “cloud”, predictions of 100% thunderstorms and nothing comes until several hours after the predictions, the next day, or not at all. I see condensation and wet spots on the ground and dripping off plastic siding, dripping onto the ground, yet no sign of rain until hours later. “Global Warming” turned into “Climate Change” to accommodate dropping temperatures and other weird weather phenomena taking place. It feels like, of you were to punch people in the face these days, they wouldn’t even notice. It’s beyond frustrating and painful having witnessed the increasing density in humans consciousness throughout my life, while being criticized for seeing what seems so obvious to me, but no one else around me. Clown world, prison planet, land on the walking dead. And most people would call me a downer or “negative nancy” for not being so chipper in this Disney World because everyone’s been so deeply programmed and hypnotized by their TVs and propaganda like this video.
Oh yeah, and this is the plan because it’s a hell of a way to control the population through “sudden and unexpected ‘food shortages” (coming to a grocery near you), not to mention the ability to induce “natural” disasters…while the food supply shortages are blamed on the “pandemic” and “inflation”, and maybe “Climate Change” when everyone eventually gets “climate” taxed, people keep dying from the sudden explosion of mass shootings while the gov tries to take arms away from the public, people are dying or afraid of shark attacks, people are further reluctant to fly because for some reason, airlines are all of a sudden “losing” luggage, new variants upon new variant, “Asian hate”, Black oppression, loss of women’s reproductive rights, “white privileged”, “white supremacists”, etc….it doesn’t end. They come up with something new every f*cking day just to rile people up and overwhelm them, create deep fear and desperation, and to create strong opposition and deep division amongst the public so we create our own downfall. Duh! Put two and two together. The “New World Order” rebranded as “The Great Reset” is in full effect, and if people can’t add the simple math up, we’re all going to be f*cked. Stop willingly hypnotizing yourselves and throw the f*cking TV out. I did so about 20 years ago because I already had a clue of the propaganda machine even years before then. There’s sh*tloads of information online (while it lasts) on gov, media, medical industry complex has f-ed countless innocent people over. Jesus.
I saw noctilucent clouds in the sky above Anza Borrego Desert State Park in December 2021. They were shimmering like no clouds I ever saw before. Very beautiful. I took a few photographs.
God damn these scientists.
Everything always worries them and that makes worried!
Here in southern Finland I have been watching these clouds this whole week! What an awesome video, cheers mate!
Astrum with the clickbait titles again. This video didn't really explain why Scientists are worried.
Change your definition of the word worry. They sent a satellite of the study in the mesosphere and its clouds I think it matters to scientists
worry is care, care is interest, scientists are interested
(in understanding what causes the dust)
i just saw it 20 minutes ago in Denmark, at 00:35 AM !!! amazingly beautiful !
so umm where is the part where they are worrying scientists???? i hate click bate.
They sent asatelite up to study them, more than other clouds get
I've seen these occur many times from my window facing south in the city of Middelburg, The Netherlands.
It is a gorgeous event indeed.
1st one to comment!
ya did it
Im sure your trophy is on the way 🙄
@@australien6611 haha
🏆
I saw beautiful translucent clouds late at sunset last night in San Antonio. Very mesmerizing.
Astrum is so beautiful to watch. I am glad it exists. Thank you Alex, you’re truly an ease to the soul.
haven't seen a noctilucent cloud, but up around 7,500 feet I have seen rainbow-coloured clouds on several different occasions. sometimes we see them down here, too, which is about 3,500 feet. they are very striking indeed, not to mention very beautiful. thanks for the explanation, dude!!
First I’ve heard of these clouds. But since you say they can be caused by rockets, yes, I’ve seen them a few times due to rocket launches from Vandenberg “Space Force” Base, aka Air Force Base in California. Very beautiful indeed!
Well, now I'm really confused, so some questions for clarification please if I may❓
1. Why do Noctilucent clouds only appear in the northern hemisphere?
2. What is it I have seen in my southern hemisphere location of between 20°S- 25°S which I always assumed to be these cloud formations.
3. If I got it wrong and they do inhabit the southern skies as well, are they in a corresponding latitude range?
4. Since the latitudes that I have seen them from (20°S- 25°S in Queensland, Australia), don't correspond to 50°N-70°N that you are talking about, what's going on?
5. What have I been looking at all these years⁉🕵♂🤷♀
TIA
I was going to comment the same.
I have also seen this clouds here in the southern hemisphere... I'm about the same latitude but in Brazil.
I saw it a few weeks ago about half an hour after the sunset. I figured it could only be extremely high clouds still reflecting sun light high up in the atmosphere. Oddly enough, here is winter instead of the northern hemisphere summer.
@@tellurian434 it's said to be methane reacting with oxygen up there to make water and CO2. The water vapor then collects onto dust from volcanoes or meteors
I'm too far south in NC to be sure I've seen these, but have seen some pretty amazing clouds. Grandad some 60 years ago showed me sun dogs, bright spots on each side of a setting sun reflected on very high thin icy clouds. The name comes from the idea of 2 guard dogs sitting on each side of a fireplace and sometimes the bright spots show some rainbow colors. Being a cloud watcher since childhood I feel the shapes of clouds are changing. As more energy is in our atmosphere from warming we get to see weather not seen in recent history.
