Video by Brady Haran
"Gentle explosion" might just be one of the funniest sensible combinations of words that i've ever heard.
These are my favorite types of Deep Sky videos. Thanks.
2:12 "... why would it be pointing directly at Earth?". * cue eery music *
Because humans at this point in time and space are the pinnacle of universal heirarchy. We know everything, right? That's space 101 bro....
Click humor button...now
Jetpowered1,
It's not pointing at us. It's pointing at someone much more important behind us.
aliens are making a celestial "look behind you" joke?
How did I miss this one? I love the Deep Sky series. I enjoy all of Brady's Videos and Deep Sky series is of particular interest to me.
Thank you - continuing to enjoy your Messier Presentations.
I love getting on a new video quickly.
FINALLY! Another Deep Sky Video. I really missed those.
I'm glad you talked about it possibly just being an statistical outlier at end. While it's definitely interesting to think about what mechanics could cause such a formation, it doesn't seem like that a big of a abnormality, in other words: looks a lot like random noise.
Glad to see Deep Sky Videos is back!
Aliens? Definetly Aliens!
+Lorenz Zahn
They have made a cropcircle in the star-cluster! This is getting rediculous. Their vandalism has gone too far! We need to draw a line in the sand..... and... well, I don't know what comes after. Somehow that always fixes all problems, like as if people are afraid of what comes next. We need to forbid the aliens and then we need an international scientific experiment to conclude what actually happens after the line is drawn in the sand... physically... chemically... vexillologically.
+Lorenz Zahn Thumbnail says it all.
ahhhh finally :P iv been dying for another deep sky vid thanks Brady
Isn't it related to the situation where massive objects bend the light? It could be explanation why it is pointing directly into us. Possibly the stars in this cluster are quite massive?
You say that M26 is messy, ay?
+lSupernova426l It's Messier than others.
This joke is so old
@@prateekgupta2408 Not for this open cluster. It isn’t old.
audio feels kind of mushed on this video, am I the only one? I have to turn up treble all the way to be able to better understand what he's saying. thanks for the video!
The fact that the circle showing the dark region is off a bit to upper left side is making me pull hair out of my head ... arrrrgh :D
what about a black hole In the open cluster pulling the stars slightly in by gravitational pull? is there a lil black hole in M26???
I love this channel, with a passion!!... But when are you gonna cover M87... I wanna know more about that humongous jet!! Thank you SO much for this channel (and your other channels, 60 Symbols in particular)
Hey Brady, is Professor Mike still making videos with you?
When you live in a big enough universe, like the one we do, statistical flukes are bound to happen...
Could it be a form of thermal collapse we see in the center of dense clusters
lol the professor with his hips on springs
It's not a very tidy cluster, but I've seen ones which are Messier
couldn't it be like a lens distortion/warping effect? So some gas is in the way acting like a lens which puts all the stars looking closer together and the edge of the lens is distorted so it looks like there's empty space as all the light is pushed to either the outside or the inside of the lens? It would also mean that the gas wouldn't have to be around the star cluster, only that it was somewhere between us and the star cluster.
+trevor Wilkinson
Gravitational lensing. I was wondering the same thing.
+CapScreenplay Not enough volumetric mass density. The individual stars are too far apart from each other to create that effect.
+quosmo1 It was my understanding that Prof. Merrifield was explaining how it couldn't be an interposing dust "bubble", and how the tell-tale sign of that would be an overall slight reduction of brightness at the center with a higher reduction at the edges of the bubble. I too thought it was a candidate for gravitational lensing, not of the stars in the cluster, but of an interposing object, but there would probably be significant distortion of the affected stars appearance.
This requires something massive enough to bend the light. Difficult to have something of such a mass between us and a cluster that is in our galaxy and isn’t directly detectable by the other gravity effects such as half the galaxy streaming towards it
Could a "middleweight" black hole have enough gravitational influence to keep the stars in a confined volume?
It would be interesting to see the orbits of the stars plotted out just to see if they are orbiting a "fixed" center of gravity or just orbiting randomly.
Watch aliens talk about the sun as just another boring star.
How did Cuffy decide on the centre of the cluster for his calculations?
My hypothesis is that the gravitational pull of the star cluster is pulling in dust and gas from the surrounding area. Because the cluster has been there so long, I do believe that the absence of gas and dust is not allowing new stars in that area to form. This I would assume at some point was assisted by the original super nova explosion pushing away some of this material. Although this would not account for the absence of this kind of structure in other star clusters.
Maybe it's just me but I really can't see any blank ring.
I think of a third option... could it be the result of an intervening gravitational lens? The edges of it could alter apparent star density creating the illusion of a cluster and a "nothing shell" making M86 an optical illusion.
The Celestials and Infinite Rakatan Empire confirmed!
If we were looking at something like the center of a galaxy we would expect strange orbits around a black body emitting X-rays north and south.
James Cutty's paper (4:34 ff) appears to be limited (magnitude red, 15.3, blue, 17.4. ) to visible light.
Are there any UV to X-ray photos of M26?
if he only watched the primer fields by martin lepoint. it would all come together like a well baked cookie shape..
Wait, some alien species went to the extreme lengths of rearranging all the stars in an open cluster to send a signal to the galaxy and you just go "meh, not worth my time ..."? Show some damn respect!
Gravitationally flat space would be my first guess.
Einstein ring. That's why you have a gap. It's because the combined gravity of the star cluster is bending the direction of the light.
hey mike wheres the striped jumper ?
[05:30] If, the cluster formed from a flattish disk, the central stars will have formed from the contracting core-leaving a spherical clearing... Alternatively a very massive companion in co-orbit will clear a spherical shell....
couldnt that "sphere of nothingness" be an instable surface? A location where a body would fall into the sphere if any peturbation occurs. Looks like a super massive dynamic system problem.
i think its just a next door type III civilization using Dyson sphere, no big deal. We can go back to poluting earth, printing money and watching sitcoms like we do everyday.
+TheSara90 I doubt there's enough material in all those stars to make up a Dyson sphere that large. So no. Unless it's made from cosmic fairy dust, the most logical conclusion is drawn towards the end of this video. It's fluke. Had there been more that presented the exact same pattern, i'd be interested in it.
lol , did u actually take my comment seriously guys? gj
+TheSara90 *drool*
+hendik hendrik
Your argument seems to be..... water-tight.
+TheSara90 exactly what i wanted to write :-)
i have an astronomy question: are stars getting smaller? i think so because every time a star explodes, it makes a nebula in which a lot of stars form, so all the new stars are smaller than the "mother". This means these smaller stars may not be massive enough to explode and soon we will run out of nebulae and consequently run out of stars
+Benjamin P material (energy) in space is constant. if we were living in a constant(volume) universe we wouldnt be "running out of stars" since the energy of one star is preserved in one or the other form. problem is,that astronomers recently found , that our universe is expending(increasing its volume) yet the (visable)energy in it remains the same. it leades to the conclusion that we will end up in a frozen universe (coz any finate mass/energy in an infinitly big volume universe is negligible). anyway that is just one hyphotesis, since we dont know what is causing universe to expend and if this effect will eventually stop and reverse itself somehow.
TheSara90
hello! i know energy+matter is constant, i suppose that because of entropy laws, that energy+matter is getting distributed more evenly on the universe, one effect of this being that the stars will only get smaller with time
+Benjamin P Yep they do get smaller. In the early universe they were gigantic (explaining the existance of very heavy elements like uranium f.e.). You could even go so far back that the whole universe actually was one big star (in a sense). Also the rate of star formation is going down rather quickly in the universe nowadays. Some say the universe is getting out of the star formation period now.
well we are lucky then we didn't exist millions of years in the future, a completely black sky is not fun
+Ronald de Rooij While there is evidence that in the early universe there were a few hypermassive stars, most stars of this era were smaller and this does not prevent massive stars from forming now either. The largest known star currently is UY Scuti, with a radius of 1708 solar radii, and there are plenty of massive stars like it.
The entire universe has never been able to be described as a star. Stars fuse hydrogen, and the early universe did very little of that. In the earliest stages of the universe, atoms did not exist until it cooled sufficiently, and even then almost every single atom was a simply hydrogen. It is only after stars that most of the elements began to form.
Heavy elements beyond iron are formed during supernovae, which still occur plentifully throughout the universe. The Stelliferous Era will last for 100 trillion years, which is admittedly not that long compared to the amount of time until the Dark Era (10^100 years) but it is still far far longer than our measly 13.8 billion years.
+Benjamin P There won't be a completely black sky for trillions of years.
Can anybody tell me the cluster size? In light years. Thanks!
I see two more circular regions of relative emptiness further out of the cluster. Anyone else?
I cannot believe that it is spherical! What's next? The moon is not a flat circle?!
What is with that turtleneck professor?
makes you think that maybe theres something there the stars are orbiting to keep it in a relatively neat sphere. im no astronomer but wouldn't there be a certain distance from a hypothetical object such as that where the gravity would no longer noticeably effect stars outside of this radius?
+eldestsucubus No. Gravitational attraction between any two bodies is calculated at an inverse square (directly proportional to the product of their masses, and inversely proportional to the square of their distance between each other). See here:
en.wikipedia.org/wiki/Inverse-square_law#Gravitation
Long story short, gravity will always affect everything at any distance. It never hits zero.
+Skeletor Jopko alright cheers for clearing that up
Spherical ummm there could be stars front and back not near the cluster while In the line of sight.
it's just a statistical possibility, universe is big, next time it won't be a cylinder but just any random form.
If you have a single star that was the source material for that cluster of stars, you can see that the stars in the middle, if not including a quasar, would likely include a white dwarf of some ancient past but more seriously; what would happen if two stars big enough to form white dwarf binary pairs do if they collided and splashed instead of reforming into a sphere, would it become diffuse as plasma eventually?
If you look carefully you can see tweety somewhere to the right, defined by an edge of nothingness.
Why couldn't just the obscuring material be behind the cluster? Wouldnt that also cause a ring of nothingness.
Reasons for analogy to circular allantoic core domain. That is, why 90um?
there's no empty circle there... there are stars all through the circle
It's caused by (what I like to call) "dark lensing" -- Some of the clusters/galaxies are close up, but there is a dark energy cluster beyond those causing a lens that make those clusters/galaxies beyond appear closer. The dark energy cluster also optically pushes edges apart making it appear empty (creating the ring.)
This happens much more often then you would think, in theory, a large portion of what we see out there is much farther away (and older) then they appear. Much older then the theorized "big bang," which did happen, but only part of a larger process called "Grand Fission" which allows for many galaxies to be 10x older then the "big bang" would leave us to believe.
;O)-
+Corvaire Wind
Allow me to be the first to congratulate you on your forthcoming "No Shit?" award :)
I won't get it until long after I'm dead, but thanks none the less ;O)-
a ring of dark matter ? or remains of the original dust cloud from which the stars formed ?
Underwear = blunder wear= thunder wear=wonder wear
You are funny
Thanks wanna get a coffee
Yup why not
Lets go
Maybe it's because of the gravity of the entire cluster.
+Daniel Dogeanu That's... not how gravity works.
+Skeletor Jopko not really, all the stars in the cluster orbit a barycenter, where the center of mass of the entire cluster is located, and consequently the direction of the pull of gravity... its a really unstable barycenter, and its probably flying around like crazy, but if you throw something at the vicinity of the cluster, its trajectory will be deflected by the pull of the cluster.
I thought the same thing as Daniel at first, that it was just some starts orbiting the cluster, but there is no explanation as to why it would form naturally, unless its just a mathematical fluke as prof. Mike Merrifield said.
couldn't a bunch of black holes be responsible for an effect like that, if they orbit the cluster in exactly that distance, flinging out any stars that where previously there? - or is that ruled out because the cluster is too young? - or because of the proposed effect that all black holes are supposed to "sink to the middle" (well - even if: that takes time, right?!) of their respective cluster?
Sounds like it's shrunk a bit & left a gap
It's a lens.
so its a black hole attracting nearby stars ...
Atlas of Creation!! really?
+Mick Hyde I'm guessing you haven't see the video where he explains why he has it?
No.
+FTLNewsFeed got a link?
Mick Hyde watch?v=Dylv1EiMejI or RUclips search "deepsky atlas of creation"
+FTLNewsFeed Many thanks for that. Funnily enough, I own the book as well. Bought it for 10p from a National Trust secondhand shop. Didn't realise what it was until I got it home. Fossil pictures are stunning though.
I LOVE astronomy...
I feel like a sphere of nothingness.Where can I get one?
PALPATINE'S BEHIND IT ALL!!!
The atlas of creation? Surely not? Yahya? Why... ? Why is that there? Debunking??? Comedy shelf?? Wha... Why>?
+Diggnuts He has a video explaining it... RUclips search: "deepsky atlas of creation" should be the first result.
Cosmic bowling made the hole? Yes, cosmic bowling by a very advanced very bored bunch of happy go lucky aliens.
BEES?!?!?!?!?!?
@ 3:11, I've called that shape, the shape of the scalable Universe. It's the shape of supernovae, quasars, whatever this is and the probability pattern of electrons in the df shell on the z-axis. Scalabal Universe.
So, how did you get into sociology?
I don't see it >.
🕶️ here have this
Go to 6:24 !!
Observation
Black hole in front of the stars creating gravitational lensing?
I say its a gravity well. from what? no idea.
Angel Gonzalez that's what I was thinking, couldn't there be just some black holes there drawing everything around it inward?
Jonathan Smit Actually I was thinking something more along the lines of there not being any globular cluster at all. just a particularly populated patch of stars sitting behind a strong gravity well acting like a lens and creating the illusion of there being a globular cluster within a dark ring.
dark matter / dark energy
+////////////\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
Dark Matter and dark Energy only seems to apply on galactic scales.This is much too small for that to be a factor, although who knows, maybe. It's just very unlikely that it would apply in this situation.

If only you knew what dark matter actually is. . ...

How about Vibrating Sine Wavefronts of Energy?
no.
Prof Merrifield can't half talk quickly (american style). I have to go back over what he has said and play it again to get it all.
