More heliophysics! Criminally underfunded. This is OUR star!
Just as important is getting a handle on whether/how our sun is different/"special" when compared to other stars. For all its "violent" behaviour observed here, old Sol is famously calm by stellar standards...
@David Peloquin And we can thank our lucky stars for that! 😜
Unfortunately,knowing more about the sun would stop some very lucrative grifts.
@@PeloquinDavid You need to go look at the 6,000 year catastrophe cycle in the geologic records.
@@ResortDog you need to put down the crack pipe.
The more I watch your channel the more I want to become an astronomer!
Honestly, thank you!
Go for it!
Good luck with your studies. 👍
@@LaunchPadAstronomy Thanks!
@@smeeself Thank you!
The less data, the more explanations - ha! So true! Thank you for this video! Great timing! After decades as an amateur astronomer, I recently (and finally!) got a solar telescope. The sun is fascinating to watch - so dynamic! Best wishes!
Still blows my mind understanding the scale of these switchbacks, coronas, and flares.
Also, imagine the headlines... 'Solar orbiter finds ice at suns pole' !!! 🤣🤣
Once again, thank you for the information, amd your efforts Christian. 🤜🤛
You are a wealth of information. Thank you for doing what you do. It it greatly appreciated. Cheers.
So nice of you to say, thank you!
@Launch Pad Astronomy Is a long, strange trip. Glad you're on the bus with us.
Appreciate the Contribution of this Study to the
better Understanding of Space Weather. 😊
I daily look if a video is uploaded from your channel..explanation is so crisp ..thank you for your efforts
Thank you so much 😀
If you set the option on the bell to include all videos, then you will get notified as soon as one is posted
resemble the effects seen in cathode rays from old-fashioned amp bulbs
Great vid, thank you! Sincerely glad you choose to not dumb down your videos too much. Sad how much is dumbed down these days.
The way you said, "And collaborators," made me rewind to hear it again and then actually laugh out loud.
thanks for the video. I am no astronomer, but I feel that solar physics is not getting enough press/hype
Endlessly fascinating. Great.
Very interesting topic! Thanks!
Very interesting! Thanks for the informative video, Mr. Ready.
Great vid! The images of the sun's poles are something to look forward to!
Thanks, and I agree about the Sun's poles. There should be some large coronal holes there!
I do find it pretty crazy that in 2023 we still haven’t seen the poles.
awesome stuff!
Your channel is literally one of the best space channels on CZcams… perfect… thanks, and best wishes +1 SUB 👍👍👍🥩🍺
Wow, thanks! I'm glad to have you along for the ride!
Solar wind switchbacks, the sun just got more beautiful.
The Ulysses probe found that above the sun's polar regions, there is more fast (and faster) solar wind than over its equator. That was surprising at the time. Which can be explained by the sun's rotation. It makes its photosphere to sink deeper (and get hotter) at the poles, while the photosphere at the equator, due to centrifugal forces is bulging outwards, more. This effect of "hot" poles should be even more prominent at fast rotating stars.
The Sun is cracking its whip 🙂
You nailed it!
Young man, I am needing me some more of that good ol' Christian Ready content ASAP! I'm trying to be patient, but I don't have that much self-control at my age. 😁 Hope you are doing great and can't wait to see what comes up next... I reckon it'll be awesome. You just make sure you have a wonderful day and then hurry up with a new video!!! 😁🍻🌌 Ok, nap time. 🌛😴
Working on it now!
@@LaunchPadAstronomy you're awesome! Can't wait.... 😁🍻🌎❤️🌮
Comment crew "Engage" ;-)
Awesome as ever.
Thanks!
Cool stuff..I'm sure that Sol is full of surprises.
Another good video
Πολλά από αυτά ήταν ελληνικά για μένα (Much of that was Greek to me), 🤣 but I love getting these reports from you. I'm no Astronomer, but I love space study science and the images we get from it. I love the Hubble Space Telescope images and look forward the new images to come from the various projects. I know the ones from Webb are manipulated, and Hubble's may be, too, but that's because we wouldn't be able to appreciate them as much if they weren't. That's what makes them so beautiful. The Eagle's Nest is a longtime favorite. Thank you, Mr. Christian.
It’s my pleasure, and thanks!
Fascinating and fantastic, thanks Christian, for someone with an already boggled mind you aren't helping me! I think its more likely to be the Anthem of the Sun, its playing for us!
You can get some pretty interesting audio out of a number of objects, even in our own solar system. If you aren't already familiar, check out Jupiter and Saturn. Their radio emissions are hauntingly beautiful :)
As always great video, very detailed. Hope you’re feeling okay…just saying.
I am, and thanks!
Thank you for dumbing it down, so I could understand just a little. 🇦🇺🙏👍
I didn’t dumb anything down. You understood just fine!
Interesting discovery! One quick note: Your audio sync is a bit off on the recordings of you speaking - about 100ms late on the video by my rough reckoning. Might wanna tweak that one in post for the next video :)
Thanks for letting me know. I'm recording the audio separately from the video and I forgot to do a proper sync. Oops!
@@LaunchPadAstronomy Yeah I figured it was probably down to having the audio come in separately. No worries :)
Dark Star Crashes, Pouring It's Light Into Ashes! ☄️
In my electromagnetism class we were taught that magnetic field lines are always closed, how can there be open lines coming from the Sun? Is that due to interaction with other magnetic fields?
You're absolutely correct. Magnetic field lines can never be truly "open" but rather must close at some point. The thing is that in the case of the Sun, their 'open' lines can extend far beyond the corona before returning, or even extend past the heliopause and reconnect with the interstellar magnetic field. It's only in the local frame that we can treat the magnetic fields as either "open" or "closed", but that still leaves plenty of room for switchbacks :)
@@LaunchPadAstronomy thanks! Love your videos btw 😃
When I imagine Solar Orbiter's view, my eyes are burning! 🌞
The sun is the most important thing in our lives. We should understand it more.
@@smeeself Yes, absolutely. Plus I love the idea of producing solar sails with close Sun approaches. 🛰
@Hiroshi the Dog Indeed. It is the source of everything. We just need to understand it better.
Would you consider doing live Q&A episodes sometime in the future?
I hadn't thought of it but thanks for the suggestion!
to my understanding the sun as plasma or ionize gas if vibrating/breathing it will generate magnetic flux just like electrical alternating current in single wire..
if this plasma has kinetic acceleration then it will generate gravity..
riveting
A switchback accelerates solar wind. Does this work sort of like a bullwhip?
Anyone here also thought about the Petrova line from Project Hail Mary?
Yes! I actually had to rewind this video a bit because I got distracted thinking about how great that book was.
@@averycockburn31Hopefully the film will not disappoint, can't wait.
The geologic record has regular 6,000 year disaster cycles, that can only be explained with solar cycles.
🙏
👍
These closed loops are not incredibly common, and therefore they don’t explain the coronal heating anomaly, correct?
The fact that several locations in the corona are 200 to 300 times hotter than the surface of the sun is the sun’s greatest anomaly.
Hi dr. Chris! Completely off topic, but why you talk in Kms. like we do here in Europe instead of miles? Are you American people adapting to our measurement system? 🤔🤔
Mostly because it's standard units that all the cool kids use, but I doubt we Americans will formally adopt them anytime soon. Or ever.
I am a ĺay man but it shows more like a Whip ... end can be determined by user
a wave on a snapped rope? what the heck does that mean
Snapped like a whip
Why do your videos sometimes go to 10 fps?
Ok so I’m not the only one who’s noticed!
What's up the audio? It's unsynced and pretty buzzy.
Really?
@@LaunchPadAstronomy I mean, it's not terrible, but it's noticeable. Might just be youtube. I guess wait to see if anyone else mentions it.
If you have seen thus space and motion eceleration.
And primordial padway behavieures .
you know exeleration can be bi the kuiperbeld pull our bi expantions of space behavieures inbetween a more thentional and less thentional braegh🙏leaking in to elchader
Sunspot is wen I the direct pull comes less pull and olso do to resistance of planners inbetween the kuiperpull and toroidal feildflow where the Jun is just behind
Oll this is seen otherwise you would not see plasma discharges in the atmosphere of the sun behind the cmsons coronal🤣💜 towart boths polars in to the sun dimention and outwars as spices of the crystal rhealm.
As response of the sphearicle translations and counterfeildflow of the kuiperbeld feild flow copassatoe and kuiper pull
Smic flux
To less negative to less counterfeildflow sun becomes eased.
Than more negative more thentional diverentio als more action.
To match negative inertia breagh on the thentional side of the sun's metaspheareic existnce as Last cold to wharm sun sicle 💜 2 to 4 mond grean sun rise and set inside the red🙏 the sun leaks out more bick pandamics🤣🤣🤣
It is somhow horible and beautiful that we humans ceap on holding on to words that looks impressive jad can not explain wat you tray to fit in your wish it should be💜🙏💜😅
Than I leurn not to what to poisoned sharings for our childeren to bent olso In these horrible understandable conditions bi informed ignurence of misconseptions🙏💜
Shame on you shame on us ull🙏
Match love to oll 💜and oll injoy beïng💜
Like we say a jear has 4 seasons jad somers be exeteration bi rising everige thentions
Sommers bi translation thentional diverentionals
And summer catalistic like last 2 jears🤣🤣🤣
Are not onley sun nound jed more eurth ring intervention towart metasphericle behavieures bound🙏
And men doing as it dus not jad understand it own existance🙏
i didn't even know the sun has poles.....
It's not "switchback" or whatever word you are using, this is called a Sigmoid and was not observed just recently.
I'm just calling it by the term referenced in the literature. See the links to the papers in the description.
How big does an object have to be to create disturbances in space? How big before the object starts to create drag?
I'll bet the phenomenon is not new. It's just a phenomenon that's evaded our notice until now. Interesting phenomenon. But really, how humano-centric can we be in talking about it?
Right, the term "new" is shorthand for "new to us." Nobody seriously thinks the Sun started doing switchbacks all of a sudden :)
03:35 -- "...quiesent..."
It's pronounced kwee-eh-snt, not kwhy-eh-snt.
Thank you, concisely explained, and you're a Deadhead!
Born and raised on the bus!
⚡ 🌞🎯😎☕
We really would be screwed without our atmosphere among other things.
You mean Magnetosphere of Earth 😊
It would be useful if we delivered the phrase "coronal Mass Ejection" as "coronal MASS Ejection". so it emphasises mass is being ejected instead of it sounding like the whole corona ejected something.
I like it how the traffic of probes in the Solar System here is already treated like a daily routine. The speaker has already arrived in a historic period of which I did not know that it has already started, of which I've thought it would start only in a few decades.
Alas, my joy concerning this revelation is curbed by a misleading makeup of the imagery shown from 11:14 to 11:15. The Sun has a diameter of just under 1.4 million kilometers. This lets appear the probe in that imagery as coming closer to the Sun than 100,000 km. The distance of seven million kilometers mentioned by the speaker is not shown as being five times the diameter of the Sun, which would have been a great opportunity for images that are both realistic and thrilling.
True. Sometimes you gotta go with the B-roll you have and not the B-roll you wish you had.
@@LaunchPadAstronomy This B-roll even can remind of CZcams clickbait, in the end. Do you really think that such a focus on pictorial vividness can appear as advisable?
I can’t imagine the footage being clickbait since the viewer would have had to have already clicked to even see that it was there :)
@@LaunchPadAstronomy Ha-ha, so it's a watch-on bait.
You could excise the probe, darken the sunlit parts, and set it into the middle of the glowing ball of the star. Thus you'll obtain a credible image like it will appear in a telephoto.
What happen
There's no such thing as an unconnected field line or a monopole. But hey, whatever ❤
It’s all about locality :)
Respectfully, "magnetic field lines" are pure abstractions to help us visualize a continuous vector field. They are no more real than lines of latitude and longitude. They cannot bend and break and do all those other things you describe. I'm not sure why this reification has such a firm hold in solar physics.
4:43 That's pretty much how most religions work.. lol. They fill the holes with stories or made up explanations. Of course, astronomers take it to the next step by gathering more data to see if they were right or not.
