To those returning and new to the channel: This video is a supercut of our previous videos about Neptune, edited into a new seamless video, and remastered in 4K resolution. We’ve added some new science updates - we explore surprising new measurements of Neptune’s temperature, reveal new images of Neptune’s aurora from James Webb, and take a look at a mysterious object in an orbital resonance with Neptune. Enjoy!
Exactly... look at the creatures that live in and around thermal vents in the ocean or the organisms that thrive in the Antarctic ice and the little bear looking thi gs that can live in the vacuum of space. 😊
It would be totally freaky if we discovered that Neptune methane is all created by life, that its whole atmosphere top levels are full of weird Neptunian microorganisms connected into a strange hive mind, mega organism like Solaris, a whole gas giant of them. That would be cool. But in Stansilav Lem style, it would be too weird to communicate with, so we would never interact with it, it would just be there, doing its own thing. lol.
Not gonna lie, I was expecting this video to be about the contents of the title. I did not expect the contents of the title to be a fraction of the video while the rest is the entire history of our investigation of Neptune.
Well unfortunately most of this video is also just made from older videos from his channel put into one video. It's kind of why I stopped watching this channel as often as I used to because I started realizing that's become a lot of his videos.
Yup. 30 seconds in, I paused and skimmed the timeline for any suggestion of a section that tackled the title. I failed to find anything. Will be ignoring this channel in future.
This channel is notorious for stretching what could be a 5 min video to 30 mins by endlessly repeating the entire history of space exploration for the first 25 minutes while talking very slowly. It's really sad because there seems to be decent production value. But there's so much filler that it's just not worth your time. DID YOU LOOK UP IN THE NIGHT SKY? THERE IS SOMETHING WE CALL SPACE. BUT WHAT IS SPACE? IT ALL BEGAN A HUNDRED KJILLION YEARS AGO. Basically this in every single video. I've seen about 15, and that's enough. If the video obviously requires you to skip through 95% of content then might as well not even give it a watch and look somewhere else. There's plenty of better space-themed channels on YT anyway. UPDATE: LMAO, I honestly did not even watch the first 5 seconds of the video when writing this and it actually says "DID YOU LOOK UP IN THE NIGHT SKY?"
I don't trust any channel that uses AI voice. Heck they likely used AI to write the script for those videos as well. Find more channels with actual human narration. So much better. Anton Petrov, Astrum, Isaac Arthur, History of the universe, SEA, John Michael Godier, and V101 space, are all good.
Hi all, PhD. student working on Uranus and Neptune here. Astrum makes a really good job at simplifying without bending our current understanding of both planets, you can trust what you are listening to. If you are interested in these worlds and have any question, feel free to ask here, I will answer to the best of my knowledge - granted I'm still learning !!
Is the diagram at 1:56 labeled wrong? I know almost nothing about orbital mechanics but since the planets orbit counterclockwise around the sun, wouldn’t the outer planet decelerate the inner planet at position A since the inner planet would be moving away from the outer planet? And then vice versa for position B. Inner planet is moving towards the outer planet so it would accelerate?
Great update. Most of us subscribers truly appreciate the effort and time spent putting such presentations together. Your channel is a wonderful astronomical resource. Kudos to all involved in this effort. It’s much appreciated🎉.
@astrumspacei used to watch your channel all the time. but nowadays when i click on an interesting title and find it was hardly discussed, or most of the info was repeat, i’m just disappointed. decided to give this one a try and same disappointment.
bro imagine going "yeah uranus is acting funky theres gotta be another planet after it and i know exactly where it is and ur friend goes alright bet lmao and then goes "what the fuck youre right"
Yeah, observing local performance of other objects is indeed a useful observational habit. Why just the other day I was coming home and passing a bend in the freeway, I noticed irregular behavior of the cars as they passed. Sure enough, there was a speed trap cop, just Neptuning away behind some bushes.
@MathCarmignani19 voyager 2 is very very very far away from anything rn im pretty sure its acc the furthest (along with voyager one) man made object from earth at 12bn miles from earth where as uranus is 1.8bn miles away so ahahha
I heard that technically Neptune was spotted by Galileo. He was observing Jupiter and saw Neptune, but that it moved so slowly that he mistakenly cataloged it as a star. Talk about a crazy coincidence.
I saw a professor present his theory that Galileo suspected Neptune's true nature, but given his troubles with the church, skating on thin ice already, he shrewdly chose to not push his luck. He left a cryptic note in the margin of his observation records that it may have moved, which may or may not have been a knowing hint.
Here is an intriguing fact about neptune. It is not actually a blue planet, Nasa enhanced the voyager photos and colored them blue because the actual photos looked exactly like Uranus, and that just wouldn't do for public interest.
@SaanMigwell As far as I know, that wasn't the reason... Neptune's photo was edited to make the details of its surface more visible. Neptune also remains blue, just in a much paler shade.
If it's a very clear night with very little light pollution you can see it unaided. I got to see Uranus on a boat in the Pacific, it was a new moon and we turned the lights off temporarily.
It's a shame the various space agencies on Earth can't work together and pool their resources. I have been fascinated by the cosmos since the first Moon landing in 1969. Love these videos.
At 6:42 the colors are approximately the same as Uranus' ... It was a NASA anomaly to publish it as blue the first time. Because it looks good with blue.
not really an anomaly, they publish false colour stuff all the time, and they said that the photo had higher contrast so that people could see the clouds better, but then people spread the photo around and forgot about that so everyone stayed beleiving that it was deep blue
One of the dreams I’ve had was to view Neptune in my telescope. I just unfortunately live in a bad area, filled with crime and light pollution. One day, I shall.
@CanisMythson Kelvin equals Celsius -273.15. This means that Neptune's average temperature of -200°C equals 73.15K. My point is that it can't drop by hundreds of degrees further. He might refer to some specific place in the atmosphere where it might have been warmer and could still drop that far or maybe he used Fahrenheit but that would be weird and should have been mentioned. Or it might just be a mistake.
The stratosphere was observed to have a significant drop in temperature, while the troposphere (which is averaging at -200°C) did not appear to have any significant change.
Great video! The information is presented in a way that non-technical people can understand. Adding the awesome photos and graphics combines for a really interesting and educational presentation. Great work! Thank you for the time and effort - it is very much appreciated!
I remember seeing a planetary alignment in the mid 1990s. That week was the only time I saw Mercury. And the alignment was quite something: Mercury, Venus, Mars, Jupiter, Saturn, and, dimly, Uranus all in a diagonal from the horizon to nearly mid-sky.
Watching your channel makes me feel like a young child again, peering into the stars, wondering about what's beyond. I wish I could go back to that time.
@ScottDJohnston Not only that, the best we can do is take pictures from outer space above the atmosphere, above Neptune.. Catching a glimpse of "ice burgs made of diamonds" floating in endless oceans of liquid hydrogen or methane or whatever, is going to stay a thing only seen in your imagination. With Europa, we can actually explore the 100 km deep ocean with a submersible since we have already figured out how to get thru the 20 km of ice so its just a matter of doing it. Wouldnt you rather explore an alien ocean, that has the potential for life, or a dead rock that we know is a dead rock? Thats crazy to me
Alex, i love these videos. watch them every night with my young son when we go to bed. you have the perfect narrator voice lol. thanks for entertaining us.
I used to have nightmares when I was a kid, with Neptune's big storm eye. Thank goodness I didn't had nightmares with Uranus, I would've felt uncomfortable mentioning it. xD
If I may just correct tiny misconception in this otherwise wonderful video, a concept that causes confusion for many people: “wind speed” on giant planets. On Earth, wind speed is defined by its speed relative to the point on the ground below. But on a planet made up mainly of gas, what does that mean? In the video you claim that Neptune has (indeed) winds of 2,160 km/h, which should be a "nearly a supersonic flow". But no, it doesn't work like that. On a giant planet, when we say, for example, that Jupiter rotates on its axis in 9 hours and 55 minutes, we're not talking about the visible clouds, we're only talking about its magnetic field, which is not perfectly symmetrical and rotates at that speed. It's a good indicator of what's happening deep inside the planet. Neptune's 2,160 km/h winds are calculated as the difference in rotational speed between each visible cloud and this deep rotational period. It is therefore not a horizontal or vertical speed, but the accumulation of a speed gradient between the depths of the planet and the visible surface. In a simplified case, if the interior of Neptune rotates at 0 km/h by convention and 10,000 km higher up at the surface we have 2,160 km/h of “wind,” each time we climb 5 km, the air only goes 1 km/h faster. In other words, it is completely calm. As we progress towards the surface, in this ideal case we will reach a speed of 2,160 km/h compared to what is happening thousands of kilometers below us, but in absolute calm, without wind or gusts. Everything would be rotating at the same speed as us. This is a far cry from “near supersonic flow”; it would be like saying that the Moon revolves around the Earth at supersonic speed, which doesn't really make sense. In reality, since, among other things, it is a sphere that rotates and there are convection currents, there are masses of air that move and rub against each other, so there are whirlwinds, and someone in a hot air balloon on Neptune might feel wind as they pass from one whirlwind to another, but we are then very, very far from 2,160 km/h. The strongest cyclones have speeds of a few hundred km/h... compared to other clouds located thousands of km away, so even our daring aeronaut in this cyclone might not notice anything until he sees other clouds far away moving in a different direction from his own.
Thanks for explaining this! Also if you’re in a less dense part of the atmosphere, even if it’s moving very fast, it’s got a lot less energy to push you around. The wind storm in the movie The Martian is a good example, it was not portrayed accurately. In reality wind at that speed in Mars’s thin atmosphere wouldn’t have been able to do that much damage.
When I was a kid, we had to do an elementary school research and presentation project on a planet. I got Neptune, so I spent a lot of time reading about it. I got my hands on a whole book about Neptune. It has a soft spot in my heart
It would be really cool if we could figure out a way to design a spaceship that could be able to take humans out to Neptune and back. There's just something about Neptune that has always been so mysterious and fascinating and just thinking about what it would be like to actually be able to fly out and see it relatively close would be incredible.
@panzerabwerkanone Oh yeah? Well the problem with that is if you make Pluto a planet, that means dwarf planets count as planets, and if that's the case, then Ceres, Orcus, Salacia, Haumea, Quaoar, Makemake, Gonggong, Eris and Sedna would all be planets too. What's easier for kids to learn: eight planets, or eighteen? It's much easier if Pluto is its own thing.
4:56 it kind of takes my breath away when I realize there’s planets out there. I mean I KNOW there are but seeing those pictures, it makes it more real to me.
Look, my wife may look like Danny DeVito but her and I have spent so many amazing evenings looking though our telescope at the tiny blue planet. It is amazing how the Webb is changing how we think about our planetary counterparts.
We steered Voyager 2 to within 5000km of Neptunes pole after bouncing it around the solar system half a dozen times? Bloody remarkable. Hooray for people that have the patience for maths
@Astrum you need to include that Neptune is not naturally blue but upscaled to blue to better see the storms. Otherwise its normal color is grey like Uranus.
I missed it. What exactly did the jwst reveal that shocked scientists? And who are these scientists who were shocked by the thing that the jwstrevealed? And what do they have to say about it? Cool video for sure but the title....
Your comment on the fact that it’s only been about one Neptune year since it was discovered made me look up Pluto. Pluto was a planet for only 1/4-1/3 of one of its orbits!
@Sanquinity Dwarf planets should be a subclass of planets, like terrestrial planets are a subclass, but according to the IAU, dwarf planets aren't planets. You'd think they'd call them something else then, but here we are.
Neptune is truly a wondrous world of extremes. From temperatures so cold it would freeze you solid super fast, to winds fast enough to shear your meat from your bones, to raining diamonds formed from methane and the strongest storms of any planet despite having little-to-no solar energy input, Neptune could give Saturn a run for its money on being the crown jewel of the Sol system.
also, which planet is the crown jewel by societies determination is subjective at this point. why not make it your crown jewel and start a new zeitgeist? after all, Jupiter is mine. Saturn is meh. The rings are overrated. Jupiter has a crazy atmosphere and at least 3 moons that have the potential to harbor life, possibly even more! Triton is jut a frozen hunk of ice. Booooooring, Who cares if it was captured planetoid and it rotates backwards. YAWN... But thats why iJupiter not only is the KING, but its my crown jewel. Besides, i never responded to the survey they sent out, on which planet is the crown jewel of our solar system.... :P
This is one of the things that I find intensely irritating with the internet as it is today and it's happening more and more. The title of this video is " James Webb's New Images of Neptune Shocked Scientists ". I am now a minute a minute and a half into the video and the narrator is talking events that happened nearly two centuries ago and I am being shown a montage of 19th century etchings. I would really like either more concisely titled content, or content that is edited within the bounds of the title.
Thanks for the nice (and cool) video Alex! Minus 274 degrees Celsius is the theoretical lowest temperature. Neptune isn't far behind (215 - 235 degrees Celsius below zero)...
Mate, I can say with no shadow of a doubt that this is the best content on RUclips, I don't just mean science based. Thank you so much for all the hard work you put in.
JWST is designed to look at faint objects far away. planets in solar system are way too bright and close to it. Imagine looking at an led right in front of your eyes. what can you see besides a bright light?
It's crazy how the French astronomer was able to observe the orbit of Uranus & determine that something was influencing the planets orbit, given it takes 84 for it to orbit the Earth.
3:07 "Neptune is the eighth, and furthest "planet" from the sun" as an early 90s kid, my sorrow over Pluto's reclassification will never fade. Regardless, I'm so glad that I was able to see the results of the fly-by! Pluto deserves so much more respect and study
Well, I learned to recite the names of the nine planets in the 1970s, and I didn't have the same reaction to the Pluto debate as you. As soon as I heard about Eris I knew this was going to force a debate about definitions. I was prepared for change because I had already learned so many new things about space in my life. In the 1980s no one had any idea what quasars were; and I heard about the inflationary hypothesis in cosmology when it was still brand new... I think the weirdest one was finding out that our galaxy has a massive black hole at its center. When I was a kid black holes seemed like such extraordinary exotic things (I mean, they are.. just knowing there are a lot of them shouldn't make us blasé!) The first actual black hole, until then just a theoretical prediction, was detected in the year I was born. So, in the 1990s I already knew that Pluto had a moon or companion we didn't know about when I was little -- discovered in 1978 (btw I am currently a fan of calling Pluto/Charon a double object) and studies of the two bodies' interactions confirmed that Pluto was way smaller than once thought ... so knowing it's just one of a number of smallish objects beyond Neptune made a kind of "click" in my mind. "Oh yeah... rocky planets ... gas/ice planets... KBOs..."
I really can't understand why people get upset about this. It wasn't arbitrary, it was a scientific reclassification due to improved knowledge about Pluto and other dwarf planets. It doesn't make it less interesting to study. The same year it was reclassified was when the New Horizons probe was launched specifically to study the Pluto system (and other Kuiper Belt objects). New Horizons is a $1 Billion+ mission, so NASA are clearly still interested in Pluto. Science isn't tradition. Scientific thinking is allowing new data to change your understanding.
I am always marveled by Neptune every single time I find it with my little 8" Dobsonian telescope. It is just a tiny, but beautiful blue spot. Thank you!
To those returning and new to the channel:
This video is a supercut of our previous videos about Neptune, edited into a new seamless video, and remastered in 4K resolution. We’ve added some new science updates - we explore surprising new measurements of Neptune’s temperature, reveal new images of Neptune’s aurora from James Webb, and take a look at a mysterious object in an orbital resonance with Neptune. Enjoy!
Exactly... look at the creatures that live in and around thermal vents in the ocean or the organisms that thrive in the Antarctic ice and the little bear looking thi gs that can live in the vacuum of space. 😊
@ledwards7171, Tardigrade, they're called Tardigrades.
@johannderjager4146thank you!😂 I wanted to call them tartarus but that's Dr Whos telephone booth.😊😊
It would be totally freaky if we discovered that Neptune methane is all created by life, that its whole atmosphere top levels are full of weird Neptunian microorganisms connected into a strange hive mind, mega organism like Solaris, a whole gas giant of them. That would be cool. But in Stansilav Lem style, it would be too weird to communicate with, so we would never interact with it, it would just be there, doing its own thing. lol.

Not gonna lie, I was expecting this video to be about the contents of the title. I did not expect the contents of the title to be a fraction of the video while the rest is the entire history of our investigation of Neptune.
Well unfortunately most of this video is also just made from older videos from his channel put into one video. It's kind of why I stopped watching this channel as often as I used to because I started realizing that's become a lot of his videos.
@bigjermboktown6976 recycling ♻️ is good for the environment and the wallet ;)
i completely forgot what the title was lol
Yup. 30 seconds in, I paused and skimmed the timeline for any suggestion of a section that tackled the title. I failed to find anything. Will be ignoring this channel in future.
This channel is notorious for stretching what could be a 5 min video to 30 mins by endlessly repeating the entire history of space exploration for the first 25 minutes while talking very slowly. It's really sad because there seems to be decent production value. But there's so much filler that it's just not worth your time. DID YOU LOOK UP IN THE NIGHT SKY? THERE IS SOMETHING WE CALL SPACE.

UPDATE: LMAO, I honestly did not even watch the first 5 seconds of the video when writing this and it actually says "DID YOU LOOK UP IN THE NIGHT SKY?"
*The more I learn about space, the clearer it becomes: the universe isn’t hostile-it’s indifferent. And that’s beautiful.*
As a Neptunian, I can confirm.
I believe you 😂
Ye I think I saw you down by the small dark spot yesterday
😂😂
How's the Wi-Fi over there?
As Uranus, I can confirm your confirmation.
9:49 "Only Hubble can probe Uranus." couldn't resist
🤣😂🤣😂🤣😂🤣😂🤣😂🤣😂🤣
You are cheap, anybody can probe uranus 🎉
😂
Did you say ur anus 😂😂😂😂😂
I chuckled a bit when i heard it then went like, oh no, not again 😅
a real human narrator. wow, thank you 🙏🏼
There's even real humans in the comments 😸
You must be new here. Welcome to Astrum. Enjoy the videos, astronomic trivia, and Alex’s relaxing voice. And have a nice day.
was thinking the same. dropped a like just for the actual human narration. crazy thats something we even have to look for
Sub to the channel. This is the best authentic astronomy channel out there
I don't trust any channel that uses AI voice. Heck they likely used AI to write the script for those videos as well. Find more channels with actual human narration. So much better.
Anton Petrov, Astrum, Isaac Arthur, History of the universe, SEA, John Michael Godier, and V101 space, are all good.

Hi y’all, PhD diploma here. I am an actual PhD diploma so feel free to put me on your wall in your office.
What specifically are you studying about them?

@ggerhart he already said it: he's studying Uranus.
My proctologist is working on my anus

@seanaldthesean Yes, unfortunately it's been the same experience for me.
bro imagine going "yeah uranus is acting funky theres gotta be another planet after it and i know exactly where it is
and ur friend goes alright bet lmao
and then goes "what the fuck youre right"
What I love is that there will be discoveries happening today that use exactly that language 😂
Yeah, observing local performance of other objects is indeed a useful observational habit.
Why just the other day I was coming home and passing a bend in the freeway, I noticed irregular behavior of the cars as they passed. Sure enough, there was a speed trap cop, just Neptuning away behind some bushes.
Great you've got the part for the kiddies show.
Nice 80 IQ breakdown
Not voyager 2 departing straight to uranus using a rare planet alignment 😭
🤡
and they are still going not bad for spacecraft made when they where now days things are made to break
@AugustPixelzwhy are they still going is uranus that big 😭
@MathCarmignani19 voyager 2 is very very very far away from anything rn im pretty sure its acc the furthest (along with voyager one) man made object from earth at 12bn miles from earth where as uranus is 1.8bn miles away so ahahha
@fgn376 woosh
I heard that technically Neptune was spotted by Galileo. He was observing Jupiter and saw Neptune, but that it moved so slowly that he mistakenly cataloged it as a star. Talk about a crazy coincidence.
The 🙄”primitive” Dogon taught you racist dogs all you know
???
Huh? The OP didn't make any racist comments. He certainly didn't mention the Dogon people. Did you perhaps reply to the wrong comment?
@DrachenGothik666Pro Victim judging by his/her channel
I saw a professor present his theory that Galileo suspected Neptune's true nature, but given his troubles with the church, skating on thin ice already, he shrewdly chose to not push his luck. He left a cryptic note in the margin of his observation records that it may have moved, which may or may not have been a knowing hint.
This planet has intrigued me and this video came just in time, thanks!
So glad to hear it! Enjoy
Cartoon !
I remember when the Voyager 2 made it’s grand tour and the tiny blue dot (earth) that it photographed on the way out of the solar system.
Here is an intriguing fact about neptune. It is not actually a blue planet, Nasa enhanced the voyager photos and colored them blue because the actual photos looked exactly like Uranus, and that just wouldn't do for public interest.
@SaanMigwell As far as I know, that wasn't the reason... Neptune's photo was edited to make the details of its surface more visible. Neptune also remains blue, just in a much paler shade.
0:12 can you really see Uranus with the unaided eye? I’ve tried looking for it before and never seen it, I always imaged it was probably just too dim.
If it's a very clear night with very little light pollution you can see it unaided.
I got to see Uranus on a boat in the Pacific, it was a new moon and we turned the lights off temporarily.
You might need a mirror. Sorry, I had to say it
@fingersmikelike a telescope mirror?? He’s saying unaided so why do you need a mirror?? That’s just cheating
@71timmay71cuz you're looking where the stars don't shine
@71timmay71 Oh you sweet summer child
It's a shame the various space agencies on Earth can't work together and pool their resources. I have been fascinated by the cosmos since the first Moon landing in 1969. Love these videos.
If we would fund space exploration with half of the funding we spend on killing each other.
@toneloke7489 Defending sovereignty is more important than some random space rocks and balloons.
@scarecrowr Defending "sovereignty" with more than twice the budget of the world's other militaries combined, is paranoia going on insanity.
@scarecrowr " Defending sovereignty" by inciting proxy wars and pussying out of the sandbox
@scarecrowr what a naive take...
3:59 this animation of the voyager mission is marvelous
Neptune is one of my targets I need to hit with my Celestron 6SE. I have seen Uranus and wow, that perfect, tiny blue dot was breathtaking.
I've seen Uranus and Neptune with my 10" dobsonian and Neptune was small enough it was almost star-like.
@josephpeters8424 Wow, with this 6" 6SE, it will be a pinpoint, heh.
i assume your talking about a telescope and not an inter-planetary missile /joke
I’m laughing, I’m a grown man and I can’t stop laughing
“I have seen Uranus and wow”
@josephpeters8424yeah, well, mines at least 15"
6:58 nearly?
Yeah it's almost double the speed of sound, don't know what he meant with nearly
I just canclled my trip next summer. Thank you!
😂😂
Good choice, I was there several years ago, and the price of sunlight was out of this world.
@PhillipBellits the locals you gotta worry about. They over charge like crazy. 😂
I liked hearing that Neptune has many more stories to tell. Its been one of those days and thinking about Neptune and the Three Bears made me smile.
Its because we haven't been calling as often as we'd promised, honestly I understand, I'd be getting a little cold at this point too...
But we've been busy!! We're totally gonna call next week though...
It's*
At 6:42 the colors are approximately the same as Uranus' ... It was a NASA anomaly to publish it as blue the first time. Because it looks good with blue.
not really an anomaly, they publish false colour stuff all the time, and they said that the photo had higher contrast so that people could see the clouds better, but then people spread the photo around and forgot about that so everyone stayed beleiving that it was deep blue
so.. brown?
@DiggyPT Not the point. His argument was that methan create blue.
@otrondalyeah but you said it was an anomaly and it was just because it looks good with blue, i was just correcting that
@DiggyPT Yes, thank you for correcting the anomaly. U is more greenish.
One of the dreams I’ve had was to view Neptune in my telescope. I just unfortunately live in a bad area, filled with crime and light pollution. One day, I shall.
If you have a telescope, you will still be able to see Neptune. You just will have a harder time finding it.
Just view Uranus instead. All you need is a mirror.
what does crime have to do with using a telescope to peep planets?
@ErnlMontyPoonoe boom!!! hahahahahahaaha
@raidermaxx2324Apparently you've never been robbed of your telescope
you know you'r day is perfect when you get a new Astrum video !
INDEED.
Hello, I'm not Alex McColgan and today you're watching Astrum. Narrated by Alex McColgan.
I have no reason not to take him at his word !
@Ozymandi_as 🤣🤣🤣😇
I very much doubt scientists were shocked.
Flabbergasted. Dumbfounded. Speechless. Blown away.
But no, not shocked.
@zenlandzipline lol!
Maybe more like a humble "Huh. Neat."
I like to think they pulled a Spock: **raises an eyebrow,** "Fascinating."
Neptune and Uranus need more observation!🪐
I heard people do like uranus.
I finally saw it thru binoculars just the other day when it was in conjunction with saturn. Remarkably blue
Is it really? Apparently its paler than most people think
@ml_gamer8344it's hard to tell because it's so faint, but it seemed an ocean blue
@demian7567 man i want a telescope
@demian7567Through my 11 inch SCT it's incredibly blue at ~90x. Any higher and it and starts losing color because of how dim it is.
just binoculars? wow! I hope someday I can get a telescope to get a really good view of Neptune and the other planets
05:40 A 40-year-long spring? Can you imagine the pollen? My allergies would simply disintegrate me.
🤣😂
Cause of Death: pollen

The content you're here for is at 13:22
Your videos are incredibly good. Congrats and thanks.
this was really good. Thank you
13:50 dropped by "hundreds of degrees"? How is that possible given that its average temperature of -200°C is only 73°C above absolute zero?
... Measured in Kelvin?
@CanisMythson Kelvin equals Celsius -273.15. This means that Neptune's average temperature of -200°C equals 73.15K. My point is that it can't drop by hundreds of degrees further. He might refer to some specific place in the atmosphere where it might have been warmer and could still drop that far or maybe he used Fahrenheit but that would be weird and should have been mentioned. Or it might just be a mistake.
@RandomUser311I caught that mistake as well, dropping my comment here in case he responds to you
The stratosphere was observed to have a significant drop in temperature, while the troposphere (which is averaging at -200°C) did not appear to have any significant change.
@CanisMythson Kelvin does not use degrees. It's not "degrees Kelvin".
The Great Dark Spot will forever be a part of Neptune's identity
Great video! The information is presented in a way that non-technical people can understand. Adding the awesome photos and graphics combines for a really interesting and educational presentation. Great work! Thank you for the time and effort - it is very much appreciated!
That means a lot, thank you! 😊
I always love to lean more about Neptune despite it having frozen fart crystals :D
I remember seeing a planetary alignment in the mid 1990s. That week was the only time I saw Mercury. And the alignment was quite something: Mercury, Venus, Mars, Jupiter, Saturn, and, dimly, Uranus all in a diagonal from the horizon to nearly mid-sky.
Watching your channel makes me feel like a young child again, peering into the stars, wondering about what's beyond. I wish I could go back to that time.
I wish we had dedicated spacecrafts to orbit and study both Neptune and Uranus.
The latter is called CornHub 🌽 😂
meh. Europa and Titan are the GOATS for scientific exploration imo
@raidermaxx2324 They've already had missions. More would be cool, but Neptune would be amazing, as would Triton
What do you want to know?
@ScottDJohnston Not only that, the best we can do is take pictures from outer space above the atmosphere, above Neptune.. Catching a glimpse of "ice burgs made of diamonds" floating in endless oceans of liquid hydrogen or methane or whatever, is going to stay a thing only seen in your imagination. With Europa, we can actually explore the 100 km deep ocean with a submersible since we have already figured out how to get thru the 20 km of ice so its just a matter of doing it. Wouldnt you rather explore an alien ocean, that has the potential for life, or a dead rock that we know is a dead rock? Thats crazy to me
I do like that you can hear the enthusiasm in his voice. He clearly has a passion for his subject matter.
Alex, i love these videos. watch them every night with my young son when we go to bed. you have the perfect narrator voice lol. thanks for entertaining us.
9:59 “wind speeds on Uranus are fast, too.”
It’s the darn middle schooler in me 😪 And I don’t think he’ll ever leave 🙂↔️
Ooo spacey space time
😁
Spacey McSpaceface
That's a different channel
Doink
Thank you, Alex. That was a fascinating watch!
I used to have nightmares when I was a kid, with Neptune's big storm eye.
Thank goodness I didn't had nightmares with Uranus, I would've felt uncomfortable mentioning it. xD
Very cool, thank you for such a comprehensive overview!
Love this channel, it's brought me and my parents together for the first time in years, thank you for your work it's amazing!
Really helpful! Thank you
If I may just correct tiny misconception in this otherwise wonderful video, a concept that causes confusion for many people: “wind speed” on giant planets.
On Earth, wind speed is defined by its speed relative to the point on the ground below. But on a planet made up mainly of gas, what does that mean?
In the video you claim that Neptune has (indeed) winds of 2,160 km/h, which should be a "nearly a supersonic flow". But no, it doesn't work like that.
On a giant planet, when we say, for example, that Jupiter rotates on its axis in 9 hours and 55 minutes, we're not talking about the visible clouds, we're only talking about its magnetic field, which is not perfectly symmetrical and rotates at that speed. It's a good indicator of what's happening deep inside the planet. Neptune's 2,160 km/h winds are calculated as the difference in rotational speed between each visible cloud and this deep rotational period. It is therefore not a horizontal or vertical speed, but the accumulation of a speed gradient between the depths of the planet and the visible surface.
In a simplified case, if the interior of Neptune rotates at 0 km/h by convention and 10,000 km higher up at the surface we have 2,160 km/h of “wind,” each time we climb 5 km, the air only goes 1 km/h faster. In other words, it is completely calm. As we progress towards the surface, in this ideal case we will reach a speed of 2,160 km/h compared to what is happening thousands of kilometers below us, but in absolute calm, without wind or gusts. Everything would be rotating at the same speed as us.
This is a far cry from “near supersonic flow”; it would be like saying that the Moon revolves around the Earth at supersonic speed, which doesn't really make sense.
In reality, since, among other things, it is a sphere that rotates and there are convection currents, there are masses of air that move and rub against each other, so there are whirlwinds, and someone in a hot air balloon on Neptune might feel wind as they pass from one whirlwind to another, but we are then very, very far from 2,160 km/h. The strongest cyclones have speeds of a few hundred km/h... compared to other clouds located thousands of km away, so even our daring aeronaut in this cyclone might not notice anything until he sees other clouds far away moving in a different direction from his own.
Thanks for explaining this! Also if you’re in a less dense part of the atmosphere, even if it’s moving very fast, it’s got a lot less energy to push you around. The wind storm in the movie The Martian is a good example, it was not portrayed accurately. In reality wind at that speed in Mars’s thin atmosphere wouldn’t have been able to do that much damage.
Thank you for that explanation.
When I was a kid, we had to do an elementary school research and presentation project on a planet. I got Neptune, so I spent a lot of time reading about it. I got my hands on a whole book about Neptune. It has a soft spot in my heart
The Neptune and Pluto Voyager flybys were probably the reason I have had such an interest in space since the early 90s.
did they really fly by pluto? i thought that was new horizons
@coolTOM6547This is correct, I'm just getting senile in my dotage. 😅
"Back in my day Pluto was a planet" *grumble grumble*
@RwnEsperlmaooo its all good brother 😂
Thanks for this great vid!
I wish NASA had the funding for a Neptune Orbiter mission
Your inner world is much more vast and interesting than the physical universe
@joshnordin4043the universe created my inner mind
@blythesprite7096not your inner mind your inner world. Your mind is just a small part of it.
too bad we elected trump who let elon doge NASA out of existence by almost completely defunding it. Your only hope is china from now on .
It would be really cool if we could figure out a way to design a spaceship that could be able to take humans out to Neptune and back. There's just something about Neptune that has always been so mysterious and fascinating and just thinking about what it would be like to actually be able to fly out and see it relatively close would be incredible.
If Neptune were to have an extreme shift in its orbital dynamics, you can kiss Uranis goodbye.
good thing neptune wont have an extreme shift of orbital mechanics then
Seriously brings a whole new meaning to "winter is coming."
Meh, not really. With only 10 K difference, whatever you're wearing to stay toasty down there will probably be fine all "year" round ;)
"The final Planet - Neptune" ... sad Pluto noises.
Pluto is still a planet in my book.
@AnakinSANE MPAPA! Make Pluto A Planet Again!
@panzerabwerkanone Oh yeah? Well the problem with that is if you make Pluto a planet, that means dwarf planets count as planets, and if that's the case, then Ceres, Orcus, Salacia, Haumea, Quaoar, Makemake, Gonggong, Eris and Sedna would all be planets too. What's easier for kids to learn: eight planets, or eighteen? It's much easier if Pluto is its own thing.
Pluto is still our 9th planet , we shall never forget
What a clear and great video, thanks!
Finally a video about what's next to Uranus.
Wrong -tube lmao 😂
Personally I'd like to hear more about what's inside Uranus
Cool video! Thanks!
Don't book Netune for your hols this year.
Wait for summer on Neptune 😂
*Gemini Home Entertainment intro starts playing*
4:56 it kind of takes my breath away when I realize there’s planets out there. I mean I KNOW there are but seeing those pictures, it makes it more real to me.
I remember feeling that way when I saw the pictures of pluto for the first time. The first new planet pictures to come out in my lifetime.
FRR it’s wild to think about it
Every new exoplanet announcement gives me this feeling too
That was excellent. Fascinating. Thank you very much!
Climate change on Neptune. Imagine that.
It’s because there’s no carbon tax on Neptune!
Definitely due to poor people having vehicles and heating their homes.
Look, my wife may look like Danny DeVito but her and I have spent so many amazing evenings looking though our telescope at the tiny blue planet. It is amazing how the Webb is changing how we think about our planetary counterparts.
I've come to appreciate your voice, dude. The voice of authority on the cosmos.
That’s an honour, thank you
Always fascinating !
We steered Voyager 2 to within 5000km of Neptunes pole after bouncing it around the solar system half a dozen times? Bloody remarkable. Hooray for people that have the patience for maths
Super informative, learned a lot.
@Astrum you need to include that Neptune is not naturally blue but upscaled to blue to better see the storms. Otherwise its normal color is grey like Uranus.
6:42
It is blue (like Uranus is), just not THAT blue
Wrong. That is all.
Saw it in my 10” telescope. Pretty sure it was a tiny blue disk. Pretty sure I was’t imagining it.
dont lie its brown i just checked in the mirror yesterday
Absolutely love your videos.
I missed it. What exactly did the jwst reveal that shocked scientists? And who are these scientists who were shocked by the thing that the jwstrevealed? And what do they have to say about it? Cool video for sure but the title....
Yeah he’s clickbaiting
Incredible!
Your comment on the fact that it’s only been about one Neptune year since it was discovered made me look up Pluto. Pluto was a planet for only 1/4-1/3 of one of its orbits!
Technically is still a planet. Just a sub-class of planets now. And the king of the dwarf sub class no less.
@Sanquinity Dwarf planets should be a subclass of planets, like terrestrial planets are a subclass, but according to the IAU, dwarf planets aren't planets. You'd think they'd call them something else then, but here we are.
This should be in history books.
Neptune is truly a wondrous world of extremes. From temperatures so cold it would freeze you solid super fast, to winds fast enough to shear your meat from your bones, to raining diamonds formed from methane and the strongest storms of any planet despite having little-to-no solar energy input, Neptune could give Saturn a run for its money on being the crown jewel of the Sol system.
raining diamonds is a hypothesis but is yet to be confirmed and possibly not happening
also, which planet is the crown jewel by societies determination is subjective at this point. why not make it your crown jewel and start a new zeitgeist? after all, Jupiter is mine. Saturn is meh. The rings are overrated. Jupiter has a crazy atmosphere and at least 3 moons that have the potential to harbor life, possibly even more! Triton is jut a frozen hunk of ice. Booooooring, Who cares if it was captured planetoid and it rotates backwards. YAWN... But thats why iJupiter not only is the KING, but its my crown jewel. Besides, i never responded to the survey they sent out, on which planet is the crown jewel of our solar system.... :P
Uranus is too
amazing Alex and ty much friend!
This is one of the things that I find intensely irritating with the internet as it is today and it's happening more and more. The title of this video is "
James Webb's New Images of Neptune Shocked Scientists ". I am now a minute a minute and a half into the video and the narrator is talking events that happened nearly two centuries ago and I am being shown a montage of 19th century etchings. I would really like either more concisely titled content, or content that is edited within the bounds of the title.
Hyperbole sells.
Very well done! Thank you.
"It can sometimes be farther than Pluto"
That's on Pluto and its eccentric orbit.
Thank you for this
15:38 fun fact, the ring called La Verrier on Neptune has a sister ring on Uranus called La Derrière.
**snort-giggle** Not bad, not bad at all.
Great episode.
Thanks for the nice (and cool) video Alex!
Minus 274 degrees Celsius is the theoretical lowest temperature.
Neptune isn't far behind (215 - 235 degrees Celsius below zero)...
-273,15 celsius not -274....
Neptune is my favorite planet, so this was an immediate click. :D Love your work!
Mate, I can say with no shadow of a doubt that this is the best content on RUclips, I don't just mean science based. Thank you so much for all the hard work you put in.
This is a slop he renames the same 6 scripts. watch SEA not this private equity owned shill
Wow it’s really quite beautiful.
Why the blurry images?? If JWST can take focused images of far off galaxies then why not focused images of Neptune and the other planets and the moon?
Bc galaxies are brighter and still larger in the sky relative to the planets
JWST is designed to look at faint objects far away. planets in solar system are way too bright and close to it. Imagine looking at an led right in front of your eyes. what can you see besides a bright light?
@Denverianvery well explained thanks dude
EXCELLENT!!!
Now theyre saying theres global cooling on neptune 😮💨
And Uranus is really a black hole!
Neptune is cool, but I am always curious about Uranus.
Haha wrecked 'em!
Rectum lol
Great presentation thanks xxx
It's crazy how the French astronomer was able to observe the orbit of Uranus & determine that something was influencing the planets orbit, given it takes 84 for it to orbit the Earth.
I was equally impressed. Some people are a level of clever I can't even contemplate.
AAAAAA THANK YOU!
3:07 "Neptune is the eighth, and furthest "planet" from the sun"
as an early 90s kid, my sorrow over Pluto's reclassification will never fade. Regardless, I'm so glad that I was able to see the results of the fly-by! Pluto deserves so much more respect and study
Have you seen the Rick and Morty episode about Pluto?
Pluto most likely will end up as moon too.
@mrbejamhe's a plutonian 😳
Well, I learned to recite the names of the nine planets in the 1970s, and I didn't have the same reaction to the Pluto debate as you. As soon as I heard about Eris I knew this was going to force a debate about definitions.
I was prepared for change because I had already learned so many new things about space in my life. In the 1980s no one had any idea what quasars were; and I heard about the inflationary hypothesis in cosmology when it was still brand new... I think the weirdest one was finding out that our galaxy has a massive black hole at its center. When I was a kid black holes seemed like such extraordinary exotic things (I mean, they are.. just knowing there are a lot of them shouldn't make us blasé!) The first actual black hole, until then just a theoretical prediction, was detected in the year I was born.
So, in the 1990s I already knew that Pluto had a moon or companion we didn't know about when I was little -- discovered in 1978 (btw I am currently a fan of calling Pluto/Charon a double object) and studies of the two bodies' interactions confirmed that Pluto was way smaller than once thought ... so knowing it's just one of a number of smallish objects beyond Neptune made a kind of "click" in my mind. "Oh yeah... rocky planets ... gas/ice planets... KBOs..."
I really can't understand why people get upset about this. It wasn't arbitrary, it was a scientific reclassification due to improved knowledge about Pluto and other dwarf planets. It doesn't make it less interesting to study. The same year it was reclassified was when the New Horizons probe was launched specifically to study the Pluto system (and other Kuiper Belt objects). New Horizons is a $1 Billion+ mission, so NASA are clearly still interested in Pluto. Science isn't tradition. Scientific thinking is allowing new data to change your understanding.
Nicely done.
The fact that Neptune can be "farther out than Pluto" has nothing to do with Neptune itself. It's due to Pluto's erratic orbit.
The orbits of Neptune and Pluto are not unrelated. They're in a 2:3 resonance.
Eccentric you mean?... I dont think erratic is a good choice of words.
@ThatWinterRider I think you're right. I sit corrected.
@ThatWinterRiderIt orbits on a different axis
What a great piece of work Alex. Bravo
I am always marveled by Neptune every single time I find it with my little 8" Dobsonian telescope. It is just a tiny, but beautiful blue spot.
Thank you!
Really neat video. Thanks for the great production. Really fascinating
