M94 - Rings and Rotation Curves - Deep Sky Videos

[@MrDowntemp0]

the process of writing a telescope proposal and the way it pans out would make a great series!

[@naplesbeachfan]

Optical telescopes have given us a narrow view of space. It is now Radio telescopes that can give us a more complete view of our wonderful Universe.

The "theory of duck matter" sounds like quackery.

Pretty easy to find ducks though.

Many thumbs up for "Duck Matter". That was adorable.

[@robertmcgovern8850]

Plenty of Duck Energy on display. And of course quarks are named after seagull noises, via James Joyce ("three quarks for muster mark"). The search is on for a buffleheaded WIMP, or a grebe's boson.

[@nousernamejoshua1556]

Earth would look like what, some gas cloud or something if all water looked black and the atmosphere prevented light from escaping and hydrogen clouds, storms also black and distant light obscuring. We would certainly need a needle in a hay, stack!

[@peternakitch4167]

Please keep us in the loop about how the proposal and investigations go.

[@psygremlin1]

I absolutely love that you didn't edit the ducks out of this!

[@thedarkmaster13]

I'm just surprised they weren't an epilogue or put in a blooper reel.

[@RichardBreen]

Wonderful "narrative arc" to this video - and a cliffhanger too. I will be interested to see where this goes.

[@flynnezrabeckman]

Brilliant! Exciting to see Dr. Becky's deductive process, passion, and a plan of observation to provide more evidence!

[@gerttherude6366]

I love the talking to the cameraman thing , really helps the dynamic :) ty for making content understandable by idiots (like me) and intellectuals

[@i20010]

True, this format makes for a much livelier interview.

[@morkmon]

Ooh this telescope time proposal sounds exciting. It would be really cool to follow this process from idea to result

[@hellionfi]

I was like "Wow, that's some scientification of the popularization of science - can't wait for the results of that telescope time proposal" - and then see that most of the top comments are about ducks. They were cool too, though.

[@Olsfen1]

KZbin analytics don’t show them, but I know from experience that Brady is big in the duck community.

Be sure to check out Dr. Becky’s own KZbin channel too if you haven’t already (-:

[@annsidbrant7616]

M94 is one of my favorite galaxies, mostly because I love that bright blue ring of stars. I'm all for knowing more about this galaxy.

[@y4lnux]

I thought I was seeing a sixty symbols video, then I realized this is a new colaboration with Dr Becky :)

[@lamegoldfish6736]

Dr. Becky is incredible! 😃

[@tramsgar]

Wonderful trait to admit mixing up radius and diameter, like we all do an a daily basis! (right?)

A bit off-topic, but where is this pub? That garden looks lovely. Becky's got the best spot!

[@jakeroberts8471]

PLEASE give us any updates on this galaxy and it's dark matter controversy!!! Genuinely interested now 🌌

[@asabelesabelo1060]

Dr Becky, what does the ring on this galaxy means? for example on the mass distribution binding the galaxy

[@Hotrob_J]

I'm excited for your updated data! Science in the making!

[@ypey1]

Exiting! Cant wait for the folow up...

[@hedlund]

But you only just got here

[@garyhuntress6871]

Please submit this proposal because I want to hear the results in a future Deep Sky video!!!!!!

[@unclvinny]

Keep the Ducktor Becky videos coming, please!

[@brouquier7172]

I'm watching this more than two years after the video was published. Does anyone know if Dr Becky has actually followed through with the telescope proposal and got the data?

[@mgrenee5878]

Please keep these Deep Sky Videos coming. So interesting and entertaining.

[@theemissary1313]

Was that dr. Beaky talking about duck matter? Also, as great as it is to see another video from Deep Sky Videos I can learn a bit more about dark matter, I really want to know where this was filmed, great location.

[@ChrisTurchin]

I love these videos so much, sometimes just put the playlist on to run in the background on a lazy day. And the fact that one can read and enjoy the comments as well (mostly avoid KZbin comments like the plague) is an added bonus. 😂 #duckmatter

[@Scribe13013]

I like Dr Becky...she's full of life

[@SoleaGalilei]

Please do submit the proposal and keep us updated! Let the ducks know how it turns out too.

[@vaderdudenator1]

Soooooo is that proposal actually happening?

[@iansharmacook]

I would love to see a vid on how such proposals are put together!

[@harshraojr]

Hey Becky & Brady, this was such wonderful video on how logic and curiosity can help you ask big questions. I think everyone here would like to know what happens to the proposal. May be a series on drafting entire proposal and telescope observation will be great insight for everyone.

[@4o4o4]

Lol I only saw the thumbnail and then thought "oh cool, brady's in a Dr Becky vid"

[@blazebluebass]

yeah Becky is super cool! nice watching videos filmed outside too

[@shivercanada]

Great to see a new one!!! Haven’t been able to do any astrophotography recently this helps. 😊

[@_rlb]

The giggle at 2:48 is the best sound ever.

[@FredPlanatia]

This has been brilliant, I just like the atmosphere of casual discussion about science, while the Oxford ducks do their crazy things. You have such a knack for explaining the kernel of the science so a lay audience can understand it, and feel your excitement about it. I wondered if you have a follow up on this. There was the recent study of 6 diffuse galaxies which all apparently have no dark matter, so even if M94 ends up behaving like other spiral galaxies (having a dark matter halo) don't you still have to contend with those 6 diffuse galaxies?

[@andersf2798]

Real time science in the making. Love it.

[@thepoofster2251]

Yay Dr. Becky! She rocks

[@alansilverman8500]

It's nearly face-on, how are you getting a rotation curve out of it at all?! What's it's estimated inclination...maybe that's off ? As long as you're applying to do an IFU, why don't you also see if it's rotation curve at 21cm agrees with your observation...

[@DanielBerke]

I was wondering the same thing about getting a rotation curve from a face-on galaxy.

[@nousernamejoshua1556]

They did an IFU four years after some time ago. I didn't understand the reading, might be just purely aging stars low light buffer and not a AGN black hole.

[@i20010]

2:10 Have we re-observed/checked the rotations speeds since the 60s? With these 500 hours exposures, Im sure more un-seem before clouds/stars will be "discovered", and maybe we can get rid of this "dark" matter stage in our lives?

[@garethdean6382]

Yes, it really became an issue in the 80s when our observations began to increase, but we're still checking rotation speeds to this day. There have been improvements, but the magnitude of the effect, 4 or 5 times the regular mass content (And in some galaxies such as Dragonfly 44,, 100x the visible mass.) It's just really not possible to miss that much regular matter, even if not glowing it should obscure the stuff already there.

[@Tom-ef1mz]

Dr. Becky: We could be on to something here Brady: Sounds like great content! Let's get a proposal together! Dr. Becky: Ya, I'm not writing that.

[@DrBecky]

😂 I have so many things I’m already supposed to be writing

[@justpaulo]

We already have Qua(r)ks in physics, so I'm all for "duck matter" !

[@larryrichards9418]

I am wondering how accurate the spectral shifts can be (or how much they can tell us) since it would seem we are looking almost top down onto the galaxy. Wouldn't a more edge on galaxy (like Andromeda) give us a better estimate of velocity through spectral shifting?

[@spamboli]

that would be awesome if this informative channel with somewhat arbitrary goals directly led to useful science! make it so!

[@Etudio]

I assume you don't want Spoilers, but... Anyway, Good Work you Two!

[@RavenZahadoom]

I do hope the idea to put in a proposal is real and not just a throwaway comment. And that we are all kept informed on it. But also I have to ask, if this galaxy's apparent lack of DM is so controversial, why hasn't a IFU been done since 2009? Surely Becky isn't the first person to think of that? Again with respect to the controversial nature of the findings.

[@garethdean6382]

It's surprising, but not really 'controversial' as such; the amount of dark matter in galaxies varies, in small dim galaxies it can exceed 99% of the mass. There's current focus on other no-DM galaxies and this would just be another one to add to the pile. In a big field sometimes things like this get overlooked.

[@tramsgar]

No "extra bits" of ADD-ducks? =(

[@marpfel]

There is some mysterious behaviour of duck matter going on o.O

[@theharbinger2573]

That sounds like Brady from Numberphile - you need to get Dr Grimes and Dr Becky together in a video on something cool.

Who published the theory of Duck Matter? Duckter Becky🤪

[@garethdean6382]

A real egghead, but I think perhaps a bit of a quack.

[@nousernamejoshua1556]

The spirals are time? So maybe the extra space is compiled mirror images like a hall of mirrors. MCMDO, Sunrise sunset ² what did the southern half do?So if you could unravel all of the galaxy spirals to straight lines to form a square... it has to be square. It can't be cubed, you cant have a duck inside of a duck. How big is the square, and how much actual space? Beckster, Show off, ducks. 😄🦆🐧, just like it was yesterday 😂, hey, are there space seasons, like interferometry measures the height of time waves? We have more energetic waves but it doesn't affect seasonal time but our appointments, schedule changes through voids, which brings the next wave peak. More light more stability, but you can measure language through the troughs. Quack. We're not in space, hyperionspace moved in between us. Hyperion /haɪˈpɪəriən/, also known as Saturn VII (7), is a moon of Saturn ... by ... Orbital period: 21.276 d Rotation period: ~13 d (chaotic) Clocks ticking, Hyperion Technologies - Smart components for small satellites  Press release - 7 October 2020: Based on a cash and shares deal, Hyperion Technologies has agreed to be acquired by AAC Clyde Space. Calyde space... ugh. 🙄

[@nousernamejoshua1556]

I don't mean completely empty, I mean have some buzzing of knowing and doing, but everytime you look away and look back they have a different kind of personality of knowing and doing. It is That particle which cannot be known of its location because it is like a liar, and the cause of Brownian Motion and zwave particle duality with angles. Which was blamed on light, but is the constant fault of darkness.

[@Lunarmobiscuit]

Seems simpler to get some telescope time looking for faint spiral arms on other galaxies. Find a few more of those and the need for dark matter disappears too. No? Becky?

[@stu8506]

She's in the middle of a creek. Flash flooood!!!!

[@essaboselin5252]

Looks like the ducks are down-voting this video. That whole bit sent my mind on a Pratchett-esque tangent where, even now, ducks across England are arguing among themselves whether they should tell you where the analysis went wrong. Don't underestimate them - they're a bunch of wise quackers.

[@Kwodlibet]

It's all fun and games, but should it ever turn out that the Dark Matter is actually made of ducks Brady and Becky will have to split that Nobel Prize money.
