Not sure why im telling u this But i turned iv been shaving for the last 6 months And EVERYTIME i shave i have your vids playing Its like these vids and me shaving are a ritual 😆
while a large portion of your views (aka income) are in America, why can't you at least put the imperial measurement equivalents in text? Are you a metric elitist, a lazy bum, or just an uncaring asshole?
It still amazes me how a planet so unfathomably far away from the sun can yet still be influenced by the sun. It also amazes that in spite of the absolute frigid temperatures that if you were to stand on Neptune, the wind would shear the meat right off your bones, then whatever was left of you would fall into the mantle of Neptune and rain down as diamonds. As nice as the inner rocky planets are, the true jewels of our solar system are the gas giants, and Neptune stands alone as its own beauty and extremes. I also dread to think of the mathematical models that predicted Neptune's presence to such an accurate degree.
"It still amazes me how a planet so unfathomably far away from the sun can yet still be influenced by the sun." yeah, imagine the effects it has on a smaller rocky planetary body much *MUCH* closer +cough+
Even planet has a influence on others planets and the life in them just like the moon does it on human body. Science has to consider that in order to fully solve the mysteries of universe.
The heliosphere, roughly the sphere of the sun's influence (not including gravity) extends 123AU out. Pluto is 39 AU out, so the sun has influence is between 5x the distance away Pluto orbits.
China currently has a proposed orbiter for launch 2030 with a 2040 arrival. I haven't seen any updates for the last two years so I don't know if it is going ahead. But there is hope yet.
@@Jabjabs As far as I'm aware, it's not happening. It's simply too late for a probe as early in development as it would have to be to be ready. They are planning a Jupiter orbiter (Tianwen-3) which is intended to launch in 2028 and will reach there in the mid-2030s. This might include a smaller craft which will use Jupiter's gravity to attempt a flyby. Also, I highly doubt that they were ever seriously considering an orbiter (as opposed to a flyby). To get there in a useful timeframe requires a tremendous amount of speed and then the problem becomes slowing down enough to get captured by the planet's orbit. When NASA was doing studies for missions to the two "Ice Giants" they concluded that aerocapture (not to be confused with aerobraking, which is easier, but more fuel-intensive) might be necessary to arrive with a useful payload.
There's a once-in-about-13-year opportunity to get a gravity assist from Jupiter to Neptune. The last chance to launch a Neptune mission using to nearest alignment would be in 2031 - but it would require a very large (i.e. expensive or unproven) rocket, even with a small payload. I was recently looking through a proposal that involved multiple Inner Solar System flybys to pick up speed before reaching Jupiter, but that particular mission would have required a launch in 2026 - two years is not enough time to design, develop and build a space probe. Fortunately, NASA has - as it's highest priority for a large mission after Mars Sample Return - a Uranus orbiter. We will have another shot at Neptune after that mission launches and it would be nice to study both reasonably close together.
I'd love to see every planet get a dedicated orbiter. I'm surprised us in the USA didn't throw a dedicated probe to every planet during the great space boom. With SpaceX and other private companies making rockets available to the masses, I think it's only a matter of time before we see a Starship launch with an orbiter bound for Neptune
Same here. I’d like to think robotic probes are going to get increasingly cheaper & more capable, and that we’ll be able to send more to the outer solar system in the coming few decades…I’m hoping we’ll find something else for New Horizons to visit soon, too!
@@RAWDEAL064 most missions are colloborations with funding anyway. But the intial capital for a large network of space probes/telescopes is only something nasa has anywhere close to being able to fund intially. I think other space agencies arent necessarily deciding their budgets ;)
One thing that many might want to know about Neptune, which wasn't mentioned in the video, is the fact that apparently, it isn't as blue as it is in most photographs. When it was photographed, the pictures of Neptune were composites and never accurately reflected its true appearance. Its saturation was greatly enhanced so that more detail in its surface could be seen. Unfortunately, somewhere along the way, everyone, including the science community forgot that this was done, or weren't properly informed, and now everyone really thinks its blue, but actually, it's a near identical shade of pale teal as that of Uranus. I'm not 100% sure if this really is true, I just heard about it fairly recently. So... grain of salt. Even if it isn't blue, Neptune is still my favorite planet!
You are correct. Neptune is roughly the same color as Uranus, it was over saturated to show the cloud details better, and somewhere along the way this was poorly communicated. It should be noted however, if you do actually resolve Neptune with a telescope from Earth, the tiny little dot it will appear as will actually appear to be a darker blue than Uranus through a telescope, Uranus appears as a pale green dot instead- So I think this misconception was bolstered due to that.
Yeah it is my favourite because it's color was wrongly attributed. I am a champion of colour rights of far away planets. And I like to cuddle them to ward off their loneliness. Poor Neptune!
I'm telling you, the outer system is where it's at. Mysterious planets like Neptune and Pluto, the Keiper belt, TNOs, the Oort cloud, and the mysterious, or mythical, Planet Nine.
Agreed and Jupiter and Saturn are awesome planets as well (Saturn is my favorite planet Jupiter is second). I wonder if we’ll ever find planet 9 someday
@@aamirrazak3467 I think we'd need a serious constellation of space telescopes to catch it. And unfortunately I dont think theres the funding for it, but we have a way of coming up with genius ideas.
@@metallicamadsam As we discover more and more TNOs, I wonder if it would be possible to construct a sufficiently detailed gravitational model from all those TNOs to infer the exact orbital location of planet 9 gravitationally, not visually.
@@Transilvanian90 Theres a great video by PBS space time on this. Its equivalent to looking for a needle in a hay stack. Even if you judge its approx location, its composition, its actual oribit, size etc etc all need to measured directly. The issue will be if it does exist, and has a wacky orbit then finding it with conventional methods will require infinite resources so i think some maturation in the approach would happen. That said, this all requires money and innovation, and a good pinch of luck!
Commenting on Neptune was that Voyager 2 saw a "Great Dark Spot" in the mid-latitude atmosphere of Neptune in 1989 on it's flyby, which has not subsequently been seen to survive by Hubble images of Neptune. It is surmised that the Great Dark Spot was a anticyclone, similar to the Great Red Spot in Jupiter's atmosphere, but not as large, long lasting, or stable. There were more than one of these dark spots. It seems that Neptune's atmosphere, other than Jupiter, is the visually second most dynamic of the Solar System gas giants.
You know what makes me feel old? I grew up learning in school that "My Very Eager Mother Just Served Us Nine Pizzas." Since Pluto was kicked of the list what the heck does mother serve us now? There's no pizzas to serve.
Hypothetical mystery planets. That's what we get served now. It's a bit like a wish sandwich (put two pieces of bread together and wish there was something between them), not very satisfying.
Changes are happening on all planets in our system. The common denominator is the sun. Can you guys please do a video on our magnetic field? It seems to be changing in a way it hasn't for about 12,000 years. We're seeing auroras far south, from relatively small solar outbursts, so they shouldn't be seen so broadly. I'd like to see what the team finds out and thinks about it.
I mean they kinda already have. The video 'What the upcoming geomagnetic field reversal will do to Earth' talks about the magnetic field. Also there are a few other videos of theirs that mention the Earths magnetic field.
Interesting note on Neptune: you talked about how Neptune's relatively small amount of methane is what gives it the shade of blue, just like Uranus, although Neptune (obviously) has a darker shade of blue. However, if I recall correctly, as it turns out, Neptune is actually not that dark. In fact, I'm pretty certain that from what I've read, that when the Voyager 2 images were released to the public, there was an internal note about how the "dark blue" images were color-enhanced, kinda like how Pluto isn't really red, but brown. However, for one reason or another, this was either forgotten or not paid attention to, and any images that are taken of Neptune now that AREN'T dark blue are instead edited to look more dark blue because, well, that's how it's SUPPOSED to look, right? I'm definitely missing a few details, but from what I've heard, Neptune basically looks almost exactly like its neighbor, Uranus, and that the dark blue images were a mixup of color-enhancement and real-color images or something. Again, I'm missing some bits and pieces of info, but I only heard about this recently, so take what I'm saying with a small piece of salt.
@@psf95 University of Oxford, they re-processed the Voyager 2 images to be true colour based on the reflected light spectra and it's essentially the same shade of greenish blue as Uranus (although maybe a tiny bit darker and saturated). The original dark blue images were noted internally to be enhanced colour although eventually it stopped being described as that whenever it was used. This same study also explained why Uranus changes colour throughout its year in detail
@@poindextertunes But all planets are named after Roman gods, and a few asteroids. Btw, "Uranos" is greek, and it´s the only planet named after a Greek God. So the , hm, namespace gets crowded. And for a gas giant, it should be something important, not some hardly-known demigod. Plus, the planet is known under this name for several hundred years. What are our priorities, if we want to go through the hassle of renaming a planet just because some US-americans on the internet can´t get a pre-adolescent stupid joke out of their dirty minds? Because that´s where the "joke" resides. Uranus doesn´t have a name tag stitched in. Is it really worth the trouble, because some people imagine they are offended, or don´t have their marbles under control? As if degrading Pluto wasn´t enough turmoil. I could live with "Kronos", though . Or "Hera". But then again it would be lacking respect for William Herschel, who originally named it. And trolled us. maybe. Anyway, why? Really? Would there be more videos about it? You sure? Maybe that´s because we just don´t really know that much about it?
You forgot Saturn’s tilt too. Saturn’s tilt is similar to that of Mars, Earth, and Neptune by about 27 degrees. Meaning that the other planets that don’t follow this tilt are: Venus, Mercury, Jupiter, and Uranus.
I was thinking that a series on all of the moons would be good🙏 ...maybe on a planet-by-planet basis, 'course Jupiter and Saturn would present a problem. I suppose those could be broken up into several parts...
Gorgeous. It's incredible how much we've learned about this distant world with so few "in person" visits. I wonder what more we'll know in ten years' time!
I love all the information on the Planet, especially the Ice and Gas Giants. The Ice Giants are so mysterious in their distance from Earth and the Sun... And I love that they have rings! I do wish we could ahve observed the death of the Great Dark Spot, and that we might obsrrve a new one being born. I am certain that being able to watch a ne Dark Spot's borth would be very exciting for AStrophyisists and myself of course; likely Alex too.
Been waiting on this one. Neptune is Fascinating! Definitely learned more about Neptune in this video. I would be interested in more information about the cores of all the planets in the solar system and their magnetic fields. I always thought Neptune and Uranus cores were solid the way they had that stationary angle compared to the axis of the planet. Thanks Alex and Astrum.👍
My favourite planet. I was hoping for a 45 minute video like the Mercury one but I didn't think it's possible given the lack of information on it compared to Mercury.
Question on the speed of sound: you say around <a href="#" class="seekto" data-time="275">4:35</a> that the winds on Neptune are nearly supersonic at 2160 km/h. I have 1235 km/h as the speed of sound; should this be "nearly twice supersonic", or am I missing something?
The speed of sound is based on pressure. And the pressure should be about twice of earth so speed of sound is twice as high? Maybe i'm wrong im going based off highschool physics memory😅
@@usfrenchguy Funnily enough it's not even dependent on pressure, it's a function of temperature for a given gas. Pressure just gets the molecules closer, temperature however is their speed.
Nice video. There is so much more to learn about Neptune and the other gas giants in our solar system. I always wondered if the planets in our solar system serve a purpose other then just being. It would be interesting to think about.
I always found Neptune and Uranus so interesting. I can’t imagine what it would be like to fly through the rings of both planets and see the orbits of moons and other satellites Hopefully one day someone will be able to experience that
Best space cowboy on YT! 🫀 I have to say, after all this time... you have the perfect voice, accent and pronunciation for this topic. You sound delighted and excited, wile remaining composed and well spoken, with perfect pace. I've wondered if you were you trained in delivering exceptional talks, or just a natural communicator! 🫀 Thanks always, Alex!
That's weird. I listen to him DESPITE his weird accent (or perhaps pronunciation). I always wondered if it's a speech impediment of sorts ? It's not as strong as, say, Isaac Arthur, yet somehow more irritating. Personally, I think SEA channel has the best narrator voice... Today he delivered some interesting tidbits on Hill Sphere and I also somehow missed earlier that Triton is bigger than Pluto (!!!).
I do remember how I discovered your Chanel years ago researching for cloud formation on earth, never quite learning, as rational and support documentary are not easy to find on RU-vid.
I really want to see a dwarf planet series like vesta,make make,eris haumua and pluto most people dont know much about these dwarf planets so it would be really helpful i really look forward to it😊
<a href="#" class="seekto" data-time="306">5:06</a> Actually, the small dark spot on Neptune was actually called, The Wizard's Eye since it well resembles the eye of a wizard or resembling the evil fire eye from The Lord of The Rings. It's best to call to it, The Wizard's Eye
Sitting under an MTP pancho under the night sky. How many times have I done this? Hundreds, thousands, so many memories of serving in the army, in many different countries. With people, some of whom are not with us anymore.
Saturn is my favorite but Neptune IS very interesting. That deep color, totally solid is so mysterious. I'd be okay with sending a probe or a GO-Pro headcam to check out the place.
I'm so sick of this guys amazing videos. Bc it always makes me think deeply about things even though its pointless bc there is no understanding the universe. Love this anyway!
I saw a video which claimed that deep inside the atmosphere of Neptune, far from being icy the temperature is hotter than on Earth and hotter than on Uranus. It has long been known that Neptune has an internal heat source.
Triton is also interesting because it's closing in to Neptune, similar to Phobos on Mars, and will eventually get destroyed by Neptune's gravitational pull. The ice geysers on Triton are very particular, too.
next planet you should do is Pluto ;) Also, a topic i always found interesting is, what if Earth had more than one moon, how would that work and what would be the effect on us, lets say Triton was our 2nd moon ?
Anything passed Jupiter is immensely interesting to me, not that the rest of the solar system isn't, but it's almost the reverse of us knowing more about the surface of the Moon than the deepest parts of our ocean. It's so much harder to get the data to understand it, which for me, makes that data all the more worthwhile trying to obtain. I am so hopeful for SpaceX to succeed with Starship, my wish is that it opens the door to a plethora of outer solar system probes far exceeding the days of Pioneer and Voyager, and giving us way more data than we can cope with, but using AI, we actually can cope, and make groundbreaking discoveries daily (that's Earth-daily).
Okay, I haven’t checked yet, but where did you get those photos for the planetary rings? I absolutely love them. They just look so good. Real nice. Old science like.
I feel like we're going to eventually find that there's a good number of icy rocks that are Pluto-sized and have odd elliptical orbits like Pluto, and that it was never special to begin with, it was just the first of many. Neptune is strange and fascinating enough that in my mind it deserves the Last Planet status that it was denied for so long.
I wonder if, at some point in time, Uranus and Neptune were one Super Gas Giant that got split into two planets because something hit it or some other catastrophic event? There is a lot of similarities between the two.
wasn't there a recent paper showing the colors Uranus and Neptune are actually quite similar and not as drastically different as shown in media? I think the colors were affected by false colors given to them during the Voyager flybys.
