The layers of sound is a fascinating idea, but MAN those Whistler mode waves are terrifying. Somewhere around the internet I've seen a meme saying the sun is an eldritch creature screaming at its children, and that noise makes me agree!
I go back a few years. This sound is quite similar to the cabinet noise of a 9-speed standard tank truck traveling at 130-140 kph with moderate load and no requirement of intermediate gears.
@@richardkammerer2814Thank you for that extremely specific example
@@richardkammerer2814 oh that's a really concrete comparison! Nice!
The moment I heard these sounds (specially the whistle from the Sun's magnetic field) I immediately thought it would be a good idea for them to be used in some form of movie or something, it would make for some really good sfx/soundtrack if edited properly!
Yeah, not using any of this if I ever get a chance to use radio interference noises to depict cosmic radiation in sci-fi exterior shots. Unless the characters fly too close to the sun. *Then* I'd use the Whistler waves.
If the sound traveled at the speed of sound in air, we would hear the suns sounds from about 14 years ago.
Gaaaaaahdang that’s a fun fact
In the vaccum of space is what you mean, sounds moves at the speed of sound in air, because it's sound after all lol
What is meant by „the sound“, is the sound of the sun. And since space doesn’t conduct sound waves because of the lack of particles, the assumption is made that it would be possible. Therefore you would need to choose a medium. Water could have also been chosen, sondwaves now travel four times faster than in air. The time would shrink to only 3,5 years.
But the more familiar medium is air, thats why the formulation of the statement may have confused you.
@@abdou.the.heretic Vaccum isn't a medium in which soundwaves can travel..
Having played in marching band and intuitively knowing how long it takes for sound to get from one place to another, that makes the Sun actually sound reasonably close to us, which in a sense it is.
thank you for such good sound design on this episode, so cool to actually hear the sounds and have them explained after. so many channels might just talk about these things and not actually play the noise they're talking about it, or fail to integrate it so nicely.
This reminds me of deaf people who finally get to hear and say they were surprised because they absolutely thought the sun would be very noisy
I’ve never heard of this
You've been really knocking them out the park with these last vids. Thank you Alex & Co.
Ok now THIS is what I love about your content. Thank you , sir 😊
Thank you!
Fascinating. This is amazing, it tickles our intelligence and fuels our immagination. These reconstructed gargantuan sounds are a beautiful, powerful, terrifying and an intriguing thing, staight out from the most important body of our system.
*EXCUSE ME* !!! On the video at 2:30 it says "3.85 x 10^26 W/s"
What the *FOOOWKKKK????????? ???? I know what a WATT is but I have NEVER heard of a "W/s"
The narrator says "Watts every second" NO. There is no such unit. There is a Joule and there is a Joule per second but there is *NO SUCH THING* as a "Watt per second" or a "Watt every second". The narrator even says "3.85 x 10^26 Watts every second" No No No, this is NOT a unit. You have a choice: either Joules per second or Watts, but NOT "Watts every second".
@@simonmultiverse6349the whole thing is silly. They are taking radio waves and lowering them in frequency until they reach the sound wave level, there is zero sound coming from the sun. All of these sounds of the planets are not sounds at all, just radio and microwaves lowered in frequency. Any form of energy could be lowered to sound waves, a lightbulb, a microwave oven, and even the transmission from a radio antenna are lowered so we can hear it. They never were sound waves in the first place.
Yes, 'fascinating', and all that... but unless such information leads to something that is practically useful to us (like finally cracking the tech to make nuclear fussion reactors, or some such) then it's in essense nothing more than mere entertainment at this point.
@@sunnyjim1355 There are times that I still feel the need for childlike wonder, especially in space stuff. In the meantime we can exploit every single asteroid and crack all the secrets of physics but I still need the wonder from time to time.
@@simonmultiverse6349have you ever heard of a kilowatt hour?
Although an increase of 3 dB represents a doubling of the sound pressure, an increase of about 10 dB is required before the sound subjectively appears to be twice as loud.
True but then our ears aren't scientific instruments.
sound pressure isn't same as sound volume
of course this varies by frequency. In the most sensitive area from about 2k to 4k you need a lot less dB for a perceived change. Right at 3k a 3dB change is all thats needed. But down low at 100-300hz you need a lot more gain to perceive a noticeable difference. Fletcher-Munsson curve and whatnot.
What??!
Nuts
Kudos to the scientists that created a Probe that withstand the intense heat of the sun, so we can learn more about this fascinating, awesome ball of plasma 🌞
And thanks 🙏🏾 to you Alex, for helping us make sense of it all 😊
For real, Parker is an amazing accomplishment in heat management. This is hard to do in space!
I'd like to add thanks that the incredible man the Parker Solar Probe is named for was still living to see his namesake's launch. Now they both fly free.
It was quite simple to design I imagine. They just had to always make sure to approach the sun during the nighttime.
@@spjspj4 a person who thinks all the time has nothing to think about except thoughts
Only because the logarithmic scale is base 10 doesnt mean a change of 10 dB results in a sound being 10 times as loud, the sound "only" doubles in volume for a change of 10 dB
Astrum relives my anxiety and helps me sleep. All but AI videos, gives me the creeps
This was a delightful watch. Glad channels like this exist.
JFYI: an increase of 10dB is not an crease of ten times the loudness, but a doubling of loudness.
Still a nice video, i love how they make us hear the sun and planets.
Yup, twice the perceived volume, 10 times the energy.
@@LiamE69Had to think hard about this for a while. Yes 10dB is indeed ten times the incident power level. The concept of doubling or ten times the loudness is the one that confused me. Going from 10dB to 20dB requires ten times the sound power, so does going from 100dB to 110dB. They both cause the same subjective increase in loudness. It makes no sense dividing 20 by 10 and saying it is a doubling. Going from 110 by 100 gives a 1.1 ratio but is the same subjective increase. A doubling of power adds 3dB to the perceived loudness. Ten times the power adds 10dB. A hundred times adds 20dB.
Sounds like an old stick welder I used for years, nice hum with a hint of I might just blow up thrown in.
I love videos about the sun.. I've heard sun sounds before on other channels, very interesting it is..love the channel alex..👌👍
At 2:30, the power output of the Sun is given in "W/s" but this is an acceleration of power. The unit of power is just W or Joules/sec. These glitches are undermining the otherwise wonderful work that Alex does. Otherwise, I really like these videos. Well done, overall.
Just saw that and searched the comments. Now that this minor error is pointed out and corrected, we can resume watching this cool video.
I learnt the difference between energy and power when I was about ten years old. Spent my life watching almost everyone get it wrong.
Hahaha, me too.@@mandjaco
@@mandjaco It got corrected?
@@tonyho1959 I mean, here in the comments.
I’ve been following this channel channel for years and I’ve got to say the writing and creativity keeps getting better and better. I don’t know how Alex keeps coming up with fresh and original ideas month after month. I don’t think anyone has created a more in depth and realistic science fiction series - not only on UA-cam, but on any platform. I can’t wait to see where he takes it next!
I had the honor and pleasure to stand on top of mission control when Parker launched. The roar of the Delta rocket is something I will remember for the rest of my life. Seeing this update about the amazing science that is being done is a lovely counterpoint to that memory. Thank you.
As a ham radio operator of over 30 years, I have had the chance to listen to the sounds of massive corona ejections on HF frequencies on a number of occasions. I spent hours tuning different frequencies from 60Hz to 30MHz on AM, FM, and SSB. I did not have a general coverage receiver for frequencies above 30 MHz back then, but I do now and I am curious to give that a spin the next time there is a MCE headed this way. Yes, I am kind of geeky but Radio frequency interest me and some of the RF sounds I heard back then were not all that different from some of the audio sounds I heard here.
Auroras sound a lot more interesting, ever got those with your hardware?
@@DanSlotea Yes I have. You are correct. basically a weaker version of what I was talking about. Aurora effect and meteor showers. Both have interesting effects on how radio waves propagate on the planet. A massive corona ejection on the other hand, nearly wipes out the ability for radio waves to propagate, on many bands and all you get on the radio is the noise of the solar flare itself.
Sperging nit pick but I'm not sure watts/second is the correct unit. Watts is already joules/second. I think you mean joules/second, or Watts.
Watt hours are a thing
Agreed but again they are not a unit of power. Watt-hours is an amount of energy. A Watt-hour is 3600 Joules. @@RoboticNerd
watt per second is how fast a power source "warming up" or dying
@@sakesaurusig then it would be not to dissimilar form metres/s/s, which is acceleration, so the full term for watts per second would be joules/s/s, which would be the amount of joules per second that you are gaining in a second
This point is so nerdy, I love it!!!
Excellent presentation. Thank you Alex
That was unreal.
Subbed.
Awesome channel
This is fascinating stuff! My guess is that magnetic reconnection happens constantly at small scales, particularly as the hot/cold areas are constantly shifting and pulling the magnetic field lines with them. It's just that we can't see those smaller nano-flares because they don't release nearly enough energy to be visible against such a bright background. As supporting evidence I'd like to offer up the small "spikes" of plasma extending out of the sun's surface as seen at 5:30, which I suspect to be similar events. But that's just one possible explanation for the continuous howl ;)
Also, small correction: you quote the velocity of particles within and outside the corona as 145 m/s and 618 m/s respectively. They're actually 145 and 618 *kilometers* per second, fast enough for the solar wind to be supersonic all the way out to the edge of our solar system.
Thank you for the correction! I did think that seemed low but I didn't go back and double-check 😫
@@astrumspace What is the music used at 5:45 and 11:30? Is it generic youtube library music or a specific artist? It sounds nice and relaxing. Keep up the good work.
Wow a huge difference of perspective at this speed. This jump in speed is astonishing, is there any research suggesting the mass is conserved and it's a pure force gain? Possibly due to it reaching a certain free point where the net force just instantly triples
Your videos are forever fantastic, and we always learn so much from you. Thank you for being an inspiration for our channel.
Great video, just something to fix. At time 2' and 30" you say that nuclear reactions inside the Sun produce a certain amount of "watts every second" and you also write it down "w/s". Maybe you meant "joules every second" aka watts...
9:50 sound is like the ringing sound you get in your ears now and again... interesting.
Enjoy every moment!!!Great video!!!
Find yourselves a life partner who talks about you with at least half the excitement that Alex talks about astronomy.
That would demonstrate a true miracle.
Your videos are so relaxing sir! I struggle to fall asleep but watching your videos I’m snoring within 3mins
Brilliant video! Thanks :)
When i was younger, I thought the Sun sounded like a fire would after explosions. I now know that Space does not radiate sound
This mug creation... I simply must have it! I was wondering why Coffee wasn't good on this planet, I just didn't have that creation to consume it from!
As a power plant technician (in the US), I am well acquainted with a 60 cycle hum. The surprising thing about the sun hum at Earth orbit is it has a higher frequency. Given the suns massive size I would expect it to be much lower. I was going to also mention it’s surprising uniformity, but as it turns out, that is fixed by just getting closer.
Hello @Simple_But_Expensive,
I appreciate your insightful comment. As an astrophysicist at NASA's Jet Propulsion Laboratory with a specialization in celestial bodies, I've spent a significant portion of my career studying phenomena related to our Sun.
Your understanding of the Sun's "hum" from your background as a power plant technician is fascinating. In the field of astrophysics, we refer to this "hum" as oscillations within the Sun's body, a subject studied under helioseismology. These oscillations are the result of turbulent convection of the Sun's plasma in its outer layers.
While it might seem intuitive that a larger object like the Sun would oscillate at a lower frequency, the actual situation is a bit more complex. The Sun's oscillations are driven by a combination of factors, including its immense size, the intense heat and pressure within, and the dynamics of plasma and nuclear fusion. This results in a broad spectrum of oscillation frequencies, some of which fall in the millihertz range-higher than a 60 cycle (or 60 hertz) hum.
Regarding the uniformity of the Sun's "hum," it's true that the Sun's oscillations vary across its surface and depth. However, from our vantage point on Earth, these variations are difficult to discern due to the vast distance. As you correctly surmised, a closer examination would provide a more nuanced understanding of these oscillations.
It's always exciting when we can apply our everyday experiences and knowledge to understanding celestial phenomena. The Sun, as familiar as it is to us, is still a subject of ongoing research and continues to reveal its secrets. Your curiosity and eagerness to understand these phenomena by applying your professional knowledge are commendable.
Thank you both for explaining this in such concise detail.
@@positivefandom9066 Yes, same. There is something calming (I have OCPD) about seeing someone know (much) more than I and to not be able to find anything that seems fallacious or biased, or parroting, but people who understands both the broad concept of their field and the small details (which makes the whole).
In "English": I enjoy people who know what they're talking about, or a discussion between specialists (it can bring insights and is interesting and can learn a lot)
*TLDR;* Ahhh sweet brain stimuli! My neurons are happy:)
Unfortunately, the writing style of the second commenter appears to be very much in line with AI-generated text. Unfortunately, that response likely wasn't real
@@ricdeh1701 Sure, but so is your inhuman overuse of 'Unfortunately'. Currently 100% of your sentences begin with unfortunately, something most humans (a positive, and fortunate being) would be unlikely to do?
I've asked this question before and here's a video about it! I imagined that it would just sound like a roar not a hum. Superb Astrum!
14:02 I love the very creative delivery method of introducing… ☕️
Thank you for including the Imperial System measurements!!
Ew
@@AlecsNeo ew? Yes, I, and many others know that in most, if not nearly all cases Metric is better; but many of our brains still work best on Imperial as we were "trained" in it from a young age and throughout our lives, it is very useful to us to have both.
You saying a mere "ew" is an issue on *your* end, not ours.
The view about the Universe you give us is simply inspiring.
Truly Stupendous Alex thank you for your impeccable research and editing 🎉❤ love the space mug!
It's about time science finally perfected the idea coffee delivery vehicle. I'll take twenty! ☕
I didn't realize there were still questions that significant about the sun that we didn't have answered! If I ever wanted to go into astronomy, the sun is for sure what I'd wanna study
Many are eerily hypnotic. Thank you for sharing.
my new favorite. Amazing stuff.
Thank you for an exceptional and captivating experience.
I think Pierre Robitaille makes an excellent case for the sun being a ball of liquid metal rather than a gas plasma. You should study his work.
Pierre Marie Robitaille is the new multidisciplinary Newton of our time. His influence encouraged this European scientist to compose a new and vibrant book, "The Liquid Sun." It demonstrates the best ideas of the sun as a condensed matter entity composed of Liquid metallic hydrogen. Proof of which knocks black holes out of the fairy tale storybook. And it kicks dark matter into oblivion. Where it belongs. Donald E Scott has buttressed this view with convincing g evidence.
Yay space weather! Im fascinated by the magnetic froth that is between the boundary of the sun and space, but I only have classicaly physics training. Fun to wonder.
Dua Ra, happy new year’s week
Classical physics remains the essence of how our universe actually works. Guard it with fierceness.
@@summerbrooks9922 well, may e at classical scales. Quantum mechanics is pretty different and manifests on only a few ways at our macro scale. Astronomers still working out the curvature of the universe and the like.
I am curious and love to learn more. As an engineer I am keenly aware of how knowledge is literally power
I never thought about this!
Very glad to be apart of this LOUD civilization ⚛️✌️🎶🎵🎼
I imagine the sun would be an intense version of Hypno-toad from Futurama
The first one is focused on a signal an octave too high. It oscillates between C#2 and D2 with a constant drone underneath at C#1. The C#3-D3 audio NASA released is just a partial reconstruction of the part that is easier to hear on most devices.
Also, the Whistler-mode waves modulate much slower on average and also overlap. They sound more like a chorus of detuned digeridoos.
The raw data from these recordings has under and overtones at frequencies from way below to way above human hearing.
The animation of the nanoflares reminds me of a tungsten filament heating up outside a vacuum. The resistive material can only hold out for so long before the energy cannot be contained.
The thing to remember is that it's all just waves. Sound is merely the vibration of a medium that allows us to interpret it. While everything that occurs will cause vibrations of one form or another, the sound clips you've played here are a translation of one form of vibration to another and a scaling down of the noise level of those vibrations.
A big component of the sound seems to be similar to Barkhausen noise which emanates from fast flipping and friction between magnetic domains in solids, when an EM field is applied to it. Perhaps something similar is happening in the magnetic convection cells brushing against each other.
The sun remains a condensed matter entity and liquid metallic hydrogen. So you seem to be spot on with your idea of solids electromagnetically active.
I've always imagined the sun would sound like the hypnotoad from Futurama.
6:08 According to a few papers I read years ago, the Corona is the atmosphere for the sun. The Corona is so hot because of how loud the sun is and the Corona is dense enough to conduct sound as good if not better than our atmosphere.
I could be wrong as that was years ago.
@cocopatty WHICH PAPERS? Where? Can you provide a source citation? I want to see that.
I think it's a combination of that and the intense magnetic fields spewing out charged particles... That's what I've heard.. it's probably a combination of everything
no matter how dense the corona is... its far less dense than the sun. So that wouldnt explain why the corona is hotter than the sun.
Someone should combine all the sounds of the sun into one video, no commentary. Would be surreal.
I would imagine it would sound like billions of nuclear bombs going off constantly.
Another astrum video lets go😌
Its not that space is a vacuum, its just really thin outside the atmosphere, theres very few, very spread out molecules. There of course is a vacuum effect if you open a pressurized object, the pressures equalize, but that doesnt mean space is a vacuum. Sound could travel in space, if there were enough molecules for it to vibrate, but there isnt. Its the lack of ability, not possibility.
Correction: Every 10 decibels is a 2x increase in sound volume, NOT 10x.
If every 10 decibels = 10x sound, literally nothing we ever made would reach 190 decibels.
The "10 decibels = 10x sound" does NOT refer to sound volume, it refers to sound pressure.
The Sun being only 270dB is actually surprising.
If the vacuum was as good of a medium for sound propagation as air, we'd only be receiving sound about 47dB strong. Which means that, for example, during rainfall, you would have problems hearing it in the first place. An average conversation is louder.
It's truly fascinating that our stable, reliable little star is such a seething mass of unfathomably powerful and violent outbursts. And that it would blow out all of our eardrums from 93 million miles away if the soundwaves could propogate through space.
Now, imagine how many db a supernova would put out. Or a quasar.
There is a limit to how strong a wave of sound can be unfortunately, which means supernova aren’t actually all that loud (_in terms of sound ofcourse_)
However there is another problem.. because the waves supernova generate are so high in frequency and so high in energy that they can’t be heard as sound waves, however if these waves are stretched from space expanding then I truly wonder how a high energy wave would sound like once it is stretched enough to become a sound wave…but it might not be “audible” per say as it might break the sound wave limit I was talking about, it might require ultra high pressure gases to raise the limit just enough for it to be audible but the pressures I’m talking about are probably impossible for a gas to exist at anyways.
All of this ofcourse depends on the imaginary physics that make sound waves travel through space
Or super massive cluster and the black hole inside with the star fighting to escape
@3:20 "Species would've probably evolved with no ears, as hearing would be pointless"
Sounds exactly like my daughter's. 🤣
The Sun - the only thing louder than "The Who: Live at Leeds"!
One of the best videos you have made, the Sun holds many future keys of science 🌞
"Helioseismology, a term coined by Douglas Gough, is the study of the structure and dynamics of the Sun through its oscillations. These are principally caused by sound waves that are continuously driven and damped by convection near the Sun's surface." Caused by sound waves.
Ikuona
@@summerbrooks9922 yes. How Can I help you?
Thanks for this enlightening thought process … the thought of someone calculating how much energy the sun produces a second is intriguing
You should do a video talking about the sun fully in general. Many people think the sun is a ball of fire in space, and I’ve seen people say it’s a glass ball that’s constantly exploding, then recently I’ve heard that the sun is like that if a massive planet; but it’s mass is so strong that it’s militant like a volcano with an ocean of lava… I’m just confused about what it actually is.
I trusted you that this wasn’t bait… I trust you from here on out. You addressed the it on your first line. Thank you!
He's a real creator :D he's excellent.
Many of those other space videos out there are AI generated click baits but Astrum and SEA are real, and they're my favorite space channels!
Tbh it’s quite the testament that humans are even that close a year to what the sun burns every second. Humanity is amazing.
I love how the sun is so extra.
I was just reminded of a movie I once saw where a (hearing) young woman, whose parents are both completely unhearing, is asked by her father if sunlight makes a noise, if it shines on stuff.
I don't remember much of the movie, but I remember pondering on that question...
thumb ups and 😂😂😂 at the ad read near the end. bravo alex! bravo!
I love human curiosity that lets us build spacecraft to orbit the sun. This curiosity rightly transcends the mundane conflicts on Earth’s surface. Thanks, Astrum!❤☀️
This was amazing, thank you !!
Congratulations on the amazing technical skills and deep scientific method of creating the mugs. As a coffee lover myself, I can truly appreciate the resources poured in.
Idk how true this actually is lol but I heard on a video one time, that said if sound could travel through space that when the sun would be about to rise iit would get loader and loader and would sound similar to a hand full of jack hammed being run full speed right beside your head or something like that. It’s amazing to me how we orbit literally a giant ball of plasma that’s so hot and powerful that if it sneezed a little to hard it could be a bad time for everyone. That some sound was sounding like a dang aztec death whistle I think it’s called Jesusit sounds similar. Great content bro keep up the great work.
The sun is not a ball of plasma. It is a drop of condensed matter composed of a lattice, hexagonal planar, which chemically supports the liquid metallic hydrogen into a helium molecular into the sun's atmosphere in the photosphere. 15:09
So they are assigning sounds to different pressure waves/frequencies so it's a "best guess"
Love this video! Thank you!
The solar whistler sound waves have to be the creepiest, Horror movie sounds.
That last wound is so creepy and amazing/scary.
Those Whistler mode sounds immediately brought one word to my mind: Tardis!
If I'm not mistaken, the sun produces radio waves that could be converted to sound.
Those whistler waves proves SCP 001 is the largest pattern screamer of all, the sun.
I wonder if anyone has ever thought of comparing the audio hallucinations of someone with synesthesia looking at the sun, with the constructed sounds of the sun.
Yes, give more substance to my theory about the sound being driven by a magnetic wave, the wave is super low frequency but insanely high in amplitude.
The sun is resonating, that same resonance is a manifestation of magnetic induction.
Thanks Alex, that was neat!
Ever heard of electric sun theory? It’s very interesting theory. I personally believe electricity plays a much larger role in the universe than we think. You can’t have magnetism without electricity, and electricity without magnetism, stew on that for a second
I turned my volume up all the way and had my ear to the speaker as your voice came booming in thank you. For future videos please don’t talk over the sound you’re showing us 👍🏽
Great Explanation! 👍🏻🇺🇲
The online merch shop looks amazing. I want a hoodie. I have enough coffee cups. 😆I'm the queen of coffee cups right now.
The sun sounds like a massive campfire keeping us safe and warm throughout our trip that we call life!😎
Once more Astrum does a mess with their units. Watts every second ??? A Watt is ONE JOULE every second.
ah. the merch segué.
priceless
We should put astronauts on the sun. It's too hot? We can go at night. 😂
I love the sound of Jupiter
Saturn's sound remains screeching and haunting
@@summerbrooks9922Pluto sounds like an ambient video game OST
It's a good thing we don't hear the sounds of the universe. No real words to describe the noise of destruction of stars.
Space is hauntingly beautiful and infinitely fascinating
Solar wind sounds a lot like an ultrasound.
Please do a video on gravitational waves, the new developments regarding the detection of broader frequency waves, and what the most likely implications of these new observations are.
Gravitational waves remain a fiction invented by Nasa's fairy tale tellers.
Let’s throw the whole U2 discography into the sun and listen to what it sounds like.
As soon as I get paid i will be ordering your merch, the outer and personal space design is just soo good.
On that note, do you ship internationally?
Wow the age old mystery of the origins of the Mug, Astrum Designed them from the ground up 😂
