5:30 - hand eye coordinate skillz

[@NorrisSaiyan]

Dr. Becky you were first

[@henrikl...1264]

Why did you do that?

[@trespire]

Mr. Miyagi would approve ! Wax on, wax off.

[@jamesrockybullin5250]

Destruction time of that globular cluster: two seconds!

[@Pilk_]

Dr Becky, my heart breaks for the globular clusters too. Would the Andromeda-Milky Way merger produce brand new ones?

[@mikew6644]

Whatever pub this got filmed at looks amazing! A back terrace with creeks running on either side? Sign me up!

[@karlhenke91]

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

[@morkmon]

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!

[@mikew6644]

Yes! Same on both accounts

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"

[@Bladavia]

Seconding this. Or some kind of overview on how computing is used by astronomers and the techniques and challenges that come with it.

[@rhoddryice5412]

First computer in astronomy was a Cannon, wasn't it?

[@Eddie42023]

@@rhoddryice5412 There were several 'models' of early 20th century 'astronomical computers'. But I bet you already knew that.

I saw this globular cluster in my Dobsonian telescope, it's beautiful !!

I saw Dr Becky in my feed, she's amazing! 😉

[@Bladavia]

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.

[@syntheticsandwich190]

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.

[@rhoddryice5412]

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

Are globular cluster forming in the MW area?

Haha got The Carl Sagan feel there... didn't Cosmos begin with that "grip"? Btw is this Nottingham?

[@ArchieWilsonVocalist]

Where's the pub? I'm sure I recognise it!

[@ReadTheShrill]

Cool - now I know how to destroy a globular cluster. That could come in handy.

[@Flying0Dismount]

Dr..Becky, Ph.D in Galactic Destruction...

[@thany3]

Shoving one or two VY Canis Majoris into it, will probably do the trick as well.

[@zapfanzapfan]

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?

[@ricardoabh3242]

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!

[@the_comamba]

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.

[@Scribe13013]

Oooh I love me some Dr Becky

[@lewhensilvar3521]

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

[@CosmosJack]

5:28 Carl Sagan's spirit is still... "alive" :)

[@karlesmcquade2863]

Why do British folks spell it "centre" but not "clustre"?

[@Hailfire08]

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

[@MountainFisher]

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?

[@clementross4606]

Are these hockey pucks under the GoPro?

[@daveangels]

Only M5 left to have the first 38 done

[@grahams5871]

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? )

[@danielroder830]

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.

[@Eddie42023]

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.

[@kreestakrasta]

Would the Pleiades be considered a destroyed globular cluster and if so... When?

[@rhoddryice5412]

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

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?

[@michaelsommers2356]

Clusters, globular or otherwise, are inside the galaxy.

[@TimK-1971]

Well, we'll just have to wait and see what really happens

[@Skukkix23]

There is no better place to film a video with audio than in a park where a road goes by - prove me wrong

[@LeoStaley]

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?

[@DeepSkyVideos]

In what world do I not read the comments??!

@@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.

1:23 How could one supernova compress that HUGE cloud?

[@JustinMShaw]

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.
