Should have a special series on just weird stuff in space. It'll keep you going for years.

"It kind of goes through this weird period where it sort of tries really hard not to just collapse and die" aka life

I do not have a science background. I found the information accessible. The concepts were easy to digest. I like your level of "enthusiasm." It makes the topic a bit less dry... like butter on toast. Keep evolving. We need more Neil DeGrasse Tysons in the world.

Thank you for these. I was a fine-art major, yet in love with astronomy. I actually UNDERSTAND your explanations. Please keep them coming!

You are an excellent teacher. I can see you as a go to reference to understand anything. With 30 minutes of time you can explain what takes a whole semester for other teachers and I can understand it.

I’m sure I’m not alone in finding your channel through DeepSkyVideos, and I have to let you know that I love your take on bringing astronomy and science to the public. Please keep up the fantastic work, it’s certainly appreciated!

Thank you Dr Becky for showing yourself rearranging "speed = d/t" at the end! I get really frustrated that I always have to run it through in my head when I'm studying, so thank you for your honesty!! haha Absolutely fantasic video........space really is very weird :)

Our universe is so incredibly beautifull, it never stops to amaze me. Thanks for this awesome video dr. Becky!

The fact that you are already an astrophysicist and still need a little time to reframe the time=dist/speed formula in your mind gives me hope. Great video, loved it.

Hey Becky the sound is great in this video. You picked an object I have never seen before and it is just beautiful. I like to compare these stellar events with atmospheric events that are much faster and easier to observe form different angles. In 2009 there was one of those "fake UFOs" sighted over Norway and Russia and you can find a lot of videos by looking for "spiral ufo" or "spiral phenomenon 2009". Doug Ellison(JPL) has made an simulation of how a propellant emitting high altitude rotating object, like a rocket stage or a missile, would look when like up in the evening sky from the sun behind the horizon. Among other early evening launches of rockets like SAOCOM 1A, it is somewhat comaprable to those interstellar dust clouds, they just happen much faster. One thing I didn't knew - there is binary star systems that go in different directions? I though about inclination differences a few times, but completely retrograde like your graphic shows?

I absolutely love your channel. I love astronomy, cosmology, astrophysics, physics, fluid dynamics, quantum theory, etc. I was always strongest in math and science in school and struggled in language and history. I found out later in life I am high functioning on the spectrum. Math always had order and rules that just made more sense to me. Plus weirdly was able to understand the wave function of the electron and how it collapsed under observation. Much like me in my own life, much different when I am on my own, different when others can see me. LOL

I find you a really good science communicator. Thanks for the videos. 👍

Cool ! I appreciate the fact you can explain the complex in such a manner that I, a mere mortal, can glean a snippet of understanding. Glad I found your channel.

Wow, nicely explained! the end of the video was pure fire! both your amazing quote-phrase on the unknown & that cute microphone's misshapen hahaha Subscribed and checking your playlist, right now.

Your explanation is so clear I actually understood all that 😉 Fascinating stuff, Becky.

Absolutely fascinating. You weren't kidding when you said a privilege to see it, gotta love those one in a billion observations. Thanks for the informative videos, really making me want to learn more about it all

Dr. Becky I like your accent. Also your enthusiasm for science is infectious.

i love good stories. i love bloopers. i love the blue on the nails.

Nothing like a beautiful Astrophysicist. Great video. Love listening to someone who knows what they are talking about.

Yo Becky ! Love your Content ! I would love to give some suggestions for your videos ! You could get Pictures, Posters, a Periodic Table or a small rack with instruments and other stuff on your white background wall. Or Greenscreen/Green paint and then you also could put in a background correlating with the actual video. Other than that i love your videos and seeing as they get better and better everytime ! Keep it up :) Greetings from Austria !

Nice one!!! The fascinating sooty object aside, I especially liked your explanation of spiral structure-it made me think of the subtle idea that all astrophysical objects are mathematical objects but not all mathematical objects are astrophysical objects; all spheres and disks and that’s about it, the resultant geometries of gravity and angular momentum. Right, so thank you Dr. B! ...and do keep up the good work please :)

Wow! This was really excellent, thank you so much Dr. Becky. I especially loved how you broke down the hypothesis with the observed results - that was a really fun journey!

Just when I got the same question in my mind you said it at minute 13:17. Im totally flabbergasted and super glad that I recently discovered your KZfaq channel. Thank you so much for share your expertise and all your outstanding work! I still have many videos to watch on your channel but I'm truly facinated by your content, thank you so much Dr. Becky! 🌌😀

Hello Dr. Becky, This is Mark Morris from southern California. Not the same Mark Morris as in your video though. But I did figure out how to reconcile general relativity and quantum mechanics. Let me know if you want to converse! I don't have any collaborators yet. I'm not kidding about figuring it out. Thank you for another fantastic video! Best, Mark

What a fascinating object. Loving your channel; so glad I found it.

Love the level of your content. At least for me, hitting the sweet spot between "so basic it leaves too many why and how questions" and "I can't follow the methodological details" is pretty rare. PS: I can see Mauna Kea outside my window and spent a lot of my undergrad years in the building next to the primary authors of the paper you showed, but I'm not astronomer or physicist. Very cool to get a glimpse at the sort of stuff my neighbors are working on ;)

Yes, we seem to be privileged to see a mysterious object like this. But I feel privileged to live in a time when we have the technology to see and get closer and closer to defining the mystery of these objects. Lastly, I feel so very privileged that you take time out to communicate so many stunning and vastly interesting astrophysics phenomenon. And you do it so well that someone without any specific physics or related education can understand. So thank you very much! :)

As before, nicely explained! I don't know why, but i always end up watching the videos on this channel in the evening, at around 10pm, and even though i'm tired, my brain never hurts after watching these.

Oh, that was interesting about the buildup of shells of helium in the star. Your channel is really interesting, thank you for sharing! :)

Great topic presented very nicely. The bloopers made me laugh. Thanks.

Perhaps an image of Van Goth's "Starry Night" ( in the background) would enhance an already lovely image. Fantastic presenter and presentations, thank you, Dr. Becky.

I love the enthusiasm with which you talk about cool stuff in space. Just bumped into this channel. Watched two vids. Subscribed Edit: enthusiasm was the word I was looking for

Wow - This is a wacky one that somehow I missed before. Much food for thought! Thanks for posting!

Dr. Becky, wonderful content! Thank you for shedding light on this crazy object in our galaxy. Love your channel and look forward to more amazing videos!

How very interesting. Considering the last (and first) video of yours I watched was about the Hoag's Object, it does make me wonder what else is out there..

Hi Dr. Becky, the computers today can really help you a lot. I hope that the Webb telescope will provide us a big step forward in our knowledge of all the things you've just talked about. Of course we can all keep dreaming of strange worlds and original cosmic bodies like planets that look like discs. There are really more planets than the Kepler and friends can detect because most of the times those solar discs are in fact facing us (just like you said about those two stars). Great to hear you as always.

Dr. B, you’re a great teacher, in fact quite gifted! I saw almost the same pattern in a similar image: The Norway Spiral.

Never heard of this, thank you for explaining this.

I love your videos! Your passion while talking is so cool!!!

Love all your videos Dr. Becky, you’re the coolest

Wow! This is so cool! Also very well explained. I am impressed of the high quality of animations you show! Also keep the bloopers! Theyre really funny!

Beckster bringing the goods :) Thanks for another good one!

Dr. Becky, I just found your channel. I'm loving it. I've got my notification bell on :)

Thanks for communicating the beauty of cosmic discoveries in a beautiful easy funny concise way

Awesome! Way better audio as well. :)

Excellent! You very well explained this beautiful and weird phenomenon. Thanks, and Happy New Year!

Thank you Dr. Becky for explaining these weird phenomena in our Universe !

Dr Becky, I love seeing more of your videos on your own channel. But I hope you can get some pointers from Brady on lighting and audio recording. Regardless, I watch them all with great enjoyment. Live long and upload often - your enthusiasm is a delight.

Good sound quality, good image focus, and (obviously, as it's Dr Becky) great content. :-) Great to see your progress with camera technology! ;-)

Thanks for the great video Dr Becky!

I like what you are doing here Becky, thank you for doing these videos, I find them very entertaining and educative! :)

I can't wait to see what sort of images we get from the James Webb telescope.

Hiya Becks!!! What's up..... The Sky!

I'm so glad I found your channel, I've seen you in Brady's videos for years, and I guess I didn't pay enough attention to the comments. Anyway, I'm here now. Thanks for all you do

Another great video! Truth is definitely stranger than fiction. I think Mother Nature must be off her head sometimes!

This is a nice talk. I intend just positive, constructive feedback, but I would fix the orbital animation and some other minor things, and reduce the use of the work "like". The orbits can't be remotely like what's shown unless it's a ternary system.

Dr Becky is the best, smart and funny.

“And it was this big... honest!” Seriously though great video and much better audio 👍

Love the bloopers... Question. What is the estimated size, in our Sun, that the actual fusion is taking place. If that makes sense. Thanks.

Thank you. You've made understanding this fascinating topic very accessible!

I like your sound effects...funny good stuff!!!!

Thank you for explaining that so well Dr. B!!

It was something strange, when you explain binaries at 6:00. Then I got it. The binary must move so that they are always on the opposite side of the barycenter and never moving to eachother or other words their orbit have the same direction clockwise or anticlockwise both.

It's not a galaxy, It's a space station! ;) TY for showing this mysterious system!

AWESOME VIDEO ( and BECKY, your nails are great! :)

I like and agree with the last sentiment. What else is there above and below our galaxy that is close enough to see but hidden in darkness for not having this rare chance angle.

This is a really an excellent video. I never heard of LL Pegasi before, but it's designation indicates a variable start. It's also the first time I've heard of a spiral structure associated with a carbon star, and moreover it's illuminated by the general Milky Way background light. However, I noticed a couple of errors that should be corrected. At 1:49 into the video you show a diagram of fusion from hydrogen into helium in a star as the fusion of deuterium and tritium producing helium a free neutron and energy. In fact this does not take place in a star, but is used in hydrogen bombs and eventually in controlled nuclear fusion. The reason is that the D-T fusion has the lowest cross-section of any hydrogen isotopes. In a star such as the sun the pp chain produces in several steps helium from just protons (hydrogen nuclei), and more massive stars helium is produced through the CNO cycle, where helium is produced from hydrogen through several steps in involving isotopes of carbon, nitrogen and oxygen. The isotope tritium is radioactive with a half life ob about 13 years and plays no part in nuclear burning in stars, and deuterium is an intermediate product in the pp chain, and after being produced by the collision of two protons, immediately reacts with another proton to produce the rare isotope of helium-3, and when two helium-3 nuclei collide helium-4 is produced. The second error is at 3:06 into the video, where you show a carbon burning shell surrounding an inert O-N-Mg core. Stars with a mass like the sun never burn carbon, only stars roughly 8 times the mass of the sun have temperatures high enough for carbon burning. Stars like the sun eventually end up as a He white dwarfs.

Nice, Doc. You're doing a great science-communication channel. Keep it up.

Omg! #1 super interesting stuff, and amazing how they figured this out, and great walk through too ;) but .... #2 so i just foind Dr. Becky within last 6 months or so, with that in mind, this is how I expected an astronomer to look like... pure white background, harsh lighting, pale white skin, and BLUE FINGERNAIL POLISH!!! BRING BACK THE BLUE FINGERNAILS!!!

Just wondering, but could it be possible that the carbon is only released on one side of the star, and the star in itself is rotating? Great video, and happy you got your own channel!

thanks for existing Dr

I absolutely love these videos...how about one on the Pleiades, my favorite little constellation....

What a beautiful detective story, I hope their results get verified.

Becky, you are the Canis Majoris Ablatisque Testiculis. Love your posts!

Lol, was wondering why the red shift wasn't used to see how fast the stars orbit, but then I realized we see them at the wrong angle. I'm in that sweetspot of knowing just enough to start thinking about things, but not yet having enough knowledge to 'know' everything from the start. :-)

maybe we can revisit this guy with JWST sometime in the near future?

Great video - love the outtakes!!!

Great video, interesting stuff, is that a Lara Croft backpack your wearing?

That binary star animation at 6:00ish is odd One of them should be moving the other way around

The animation at 6:01 seems to be incorrect: the center of mass of 2 objects (the black dot on the animation) should always lie on the line connecting the objects (red and blue stars on the animation).

Brilliant, Dr Becky!

So cool... Lit by the integrated flux of the milky way. Just like the gas and dust clouds around Polaris. Very hard to image, a real challenge for amateurs like myself.

Great vid! It's nice to get something new. Keep up the good work.

Brilliant. Thanks for the learning!

Hi Dr. Becky! I've only recently started viewing your channel, and I it has become a standard viewing stop for me. :) How long does it take for the (IIRC) planetary nebula that these starts produce to no longer be identifiable as having come from a specific star (system)? My thought is that this nebula must also be relatively transitory, and that coupled with that they are produced during such a short fraction of the star's lifespan, that might be _some_ of the reason why we don't see more of them. Also: @ 06:01 in the depiction of a binary star system orbiting their common barycenter the two are depicted as orbiting in opposite directions. I went "0.o" at that, and wondered if that was possible for a long-term stable system (in my inexpert opinion I think not). Comments?

I keep being awestruck by what the Hubble reveals!

Amazing, thank you for the great explanation of this truly weird system. I would like to learn about the different types of "jets" observed and what drives them.

I love how passionate you are about this! New subscriber here :-)

I am so glad i found this channel this is so amazing!

One wonders about diamonds. I remember reading in one of Arthur C. Clark's novels that when Jupiter is transformed into a small star it threw off a massive amount of diamond which humans later used to build cities with. So I presume that since carbon is easy for stars to make and they are casting off so much of it that space is just filled with diamonds. Not just dust sized but ball sized, car sized, building sized and bigger (moon sized?) If we can ever build FTL starships it would be great to fly out to one of these carbon stars and see what the neighborhood looks like.

Great video, i love your channel! 😊👌

love these videos! please keep on the great work!

Very cool! I have a more general question about things like this, nebulae in general. What would it look like if you were inside it? Would it be like you are in a cloud? Or does it only appear cloud-like because we are so far away from it, so that it is clear if you are actually in it? I am thinking about comets' tails which, as I understand it, are actually quite whispy, and it only looks as dense as it does because of our distance from it.

Well-articulated theory . Extremely interesting!

Your binary animation showed the two stars orbiting in opposite directions, Red clockwise; blue anticlockwise. Most animations show binary stars orbiting in the same direction, clockwise or anticlockwise. Was this deliberate for this specific pair? And would you not get this spiral effect from from a binary system orbiting in the same direction?

muchas gracias , great exposition!

Better audio. Please keep those vids coming.

Great post. I have question, or rather an unfounded supposition, for you to comment on regarding an alternative attribute of the missing carbon star observations. Your statements in this video presents a case where the lack of observation is due to the orientation of the orbits of the binary stars as well as position with respect to the Milky Way (out of plane and relatively close with respect to the size of our galaxy). Assume then that there indeed are a vast number of unseen carbon stars and remnants of carbon stars disbursed outside what is left the carbon star system. Would this not account for Dark Matter?

What a most charming scientist

Great video and subject matter Becky, glad I found you, you have a new subscriber. P.s. Are you Irish?
