5:30 - hand eye coordinate skillz
Dr. Becky you were first
Why did you do that?
Mr. Miyagi would approve ! Wax on, wax off.
Destruction time of that globular cluster: two seconds!
Dr Becky, my heart breaks for the globular clusters too. Would the Andromeda-Milky Way merger produce brand new ones?
This paper works well with adding "Harry Potter and..." to the beginning of the paper name.
This is genius
I love this so much! I will start doing this with all academic papers 😂
Harry Potter and the destruction of the galactic globular cluster system
Whatever pub this got filmed at looks amazing! A back terrace with creeks running on either side? Sign me up!
AHhh Dr. Smethurst, my FAVORITE :)
I like the setting of the video, know it's because of the global situation we are in right now, but I kinda like it better than a regular office
It makes me long for a nice summer day on which to visit!
Yes! Same on both accounts
I saw this globular cluster in my Dobsonian telescope, it's beautiful !!
I saw Dr Becky in my feed, she's amazing! 😉
Always a good to start my day with a new Brady Video
Love all video with Becky Smethurst, she is so enthusiastic.
What a spectacularly beautiful filming location
3:36
Video needed - "The Astronomers History of Computing"
Seconding this. Or some kind of overview on how computing is used by astronomers and the techniques and challenges that come with it.
First computer in astronomy was a Cannon, wasn't it?
@@rhoddryice5412 There were several 'models' of early 20th century 'astronomical computers'. But I bet you already knew that.
@@Eddie42023 My comment was a pun referring to the Harvard Computers, but of course Annie Jump Cannon wasn't the only one.
@@rhoddryice5412 yep.
Very interesting video for a globular cluster one. Also I NEED to know where this small park is, it looks like such a lovely place.
And with the destruction of M14 there's only eighteen Messier objects left.
M5, 39, 47, 55, 61,
63, 69, 72, 80, 81,
84, 86, 88, 91, 94,
95, 107 & 108
There are some beautiful galaxies among them
101?
Cool video Brady, I wonder how long will it will be until all the 110 Messier objects have videos, next you’ll have to do a video for every NGC object, that would keep you busy.
If someone lived on a planet in the middle of that globular cluster, would they see any stars beyond the cluster or would it be daytime all the time?
zapfanzapfan Interesting question, when dealing with space, I go be the premises: space is really really big :)
So I would “guess” that you will see outside of the cluster but the view will be radically different of what we see.
Unfortunately I would guess that it would increase the period of Earth geocentric perspective lol
Hope someone does have your answer!
Interesting question indeed. I am not an expert on this, but according to Wikipedia the absolute luminosity of the total cluster is at magnitude -9.12. Per definition the absolute luminosity is equal to the apparent magnitude at a distance of 10 parsec, which is about 33 Light years. So the luminosity of the total cluster viewed from 33 light years away is pretty close to that of the full moon as viewed from earth. 10 parsec is also roughly the radius of the cluster, so I suppose on average the nightsky on M14 planets is as bright as our full moon (only spread over much more spherical angle).
In such a star dense region it is, however, much more likely to have a luminous neighbour close by, so there are probably some planets that have a pretty bright surface most of the time.
5:28 Carl Sagan's spirit is still... "alive" :)
Oooh I love me some Dr Becky
Cool - now I know how to destroy a globular cluster. That could come in handy.
Dr..Becky, Ph.D in Galactic Destruction...
Shoving one or two VY Canis Majoris into it, will probably do the trick as well.
Haha got The Carl Sagan feel there... didn't Cosmos begin with that "grip"? Btw is this Nottingham?
If globular clusters can be formed by a gas cloud being disturbed a supernova explosion nearby, does this mean that new globular clusters could be formed today? I thought they were all quite old
Only M5 left to have the first 38 done
Someone please tell Brady to expand the scope of this channel the way he did with numberphile. Being just about the Messier objects, and only one video per object, really limits the wonderful possibilities of this channel. He doesn't read the comments, but I think Dr Becky reads them?
In what world do I not read the comments??!
Thank You
Sir Dr Brady .
Thanks Muchly .
@@DeepSkyVideos You no doubt get comments asking you to reduce the scope of numberphile too. You can't win, sorry.
There aren’t that many Messier Catalogue objects left, so they should definitely start thinking about how they want to branch out.
@@ragnkja Brady's been at this for a while now. If he doesn't have a rough outline of a plan/direction already I'll be thoroughly surprised :)
Are globular cluster forming in the MW area?
They probably made some model that said [X] of the cluster is remaining after [Y] time and then extrapolated it to where the model said zero, so it's more of an order of magnitude estimate and doesn't actually need to define a cluster
What i wonder is, how long is the time span a dying globular cluster would already be in a state where we can not detect it anymore and don't see that there even is/was a globular cluster. If they are invisible for a large part of their later life, we are seeing less than there are.
Why do British folks spell it "centre" but not "clustre"?
I read that star clusters and especially are leftover pieces of galaxies the Milky Way has collided with and absorbed. That was deduced from the fact that they are all outside the disc of the Milky Way. Is there validity to this theory?
Where's the pub? I'm sure I recognise it!
Excellent
1:23 How could one supernova compress that HUGE cloud?
Just a guess on my part, but it could be that the supernova in question would have been from the first generation of hypergiant stars, and the gas clouds that collapsed could have already been dense enough for even a very weak shock wave far from the explosion to trigger star formation.
Would the Pleiades be considered a destroyed globular cluster and if so... When?
No. Pleiades is an open cluster and young(millions or 100's of million years old) compared to globular clusters which are Giga years old
@@rhoddryice5412 Thank you for the answer.
Hey Pleiadian lives matter
There is no better place to film a video with audio than in a park where a road goes by - prove me wrong
Does the existence of globular clusters tell us anything interesting about the early structure of the universe, or are they just inevitable objects that we would expect to form? (IOW do our best universe simulations show both galaxies and globular clusters forming? )
Well, we'll just have to wait and see what really happens
How does this timescale compare to the lifetimes of the cluster's constituent stars? Most stars evolve on a timescale below 10^10 years. Just thinking now, I realized with blue stragglers being the product of mergers, etc. THIS might be too big a topic for a single comment.
Where are the bloopers :p
Looked at Venus recently?
I prefer the futurama word for past tense of slingshot, which is slangshat.
Are these hockey pucks under the GoPro?
Dr S? So you use your Sunday name in this series of videos?
I thought that globular clusters were the stage of galaxies after they merge?
Clusters, globular or otherwise, are inside the galaxy.
You said "in 2010". Did you record the video a decade ago?
ah, where I discovered Dr. Becky! Imagine being a type 3 civilization and getting to engineer celestial mechanics on these scales! Then again... by then, would you even care?
Can’t be destroyed
whoop! : )
Why all the cuts and different camera angles? I found that distracting.
Poor thing, why don't find a sheltered place, dark and cozy and cry your heart out.
I agree. I hate the latest baumgartener restoration videos because of that
Próbàld megérteni ! Ugye sikerülni fog?
Mad ninja skilz...
Dr Becky is too cute
Lots of socializing going on here, with no precautions. Is the virus no longer a problem in the UK?
"the New Heavens and the New Earth"
Moth whisperer.
dark matter is a joke!
Dark matter lives
People in the background socializing instead of social distancing. The horror! :)
We got a pro-pandemic poster in the comments
DNA test? That would be most accurate.
Camera shaking. Zooming in and out. Switching angles every sentence. Ugh
I'll get the hang of this CZcams thing eventually - give me time!
@@DeepSkyVideos I am certain you will. Great content as usual. :-)
I liked this style
Makes it less clininal.
And still - it didn't cost you a cent.
