Am I the only one who thinks the narrator sounds like Yahtzee of Zero Punctuation fame?

Sooooooo.... any christian fundies wondering why this sort of majesty isn't mentioned in the bible? Astrophysics trumps ancient fairytales every time!

I agree, he sounds very similar to Yahtzee.

Wow lovely- I'm loving these new HD embeds. And loving more that we're not receiving the bandwidth bill.

I've looked at Omega Centauri before with my 5.1" Dobsonian, and believe it was one of the first Globular Clusters I accidentally came across just randomly moving my telescope around with the lock knobs disengaged, definite upvote here.

Also, on the topic of Dark Matter:

Dark Matter Discovered?

There was not nearly enough embuggery to be yahtzee. But a great video none the less.

It's a certain place in england.. if you come from there, you sound slightly like yahtzee. I actually heard yahtzee first and thought "hey, that sounds like my friend!"

What is with Europeans and those strange eyeglass frames?

Upvote for flawless streaming HD with no wait. . . And also something about the majesty of the universe.

So true ... we should take their children away and give them to normal glasses wearing americans.

There is no fine line between globular clusters and dwarf galaxies; the distinction is an anthropogenic arbitrary division of a continuum.

Yes. I take your point, but I dislike the use of the term "arbitrary". I would say the "fine line" is an attempt at differentiating on stable functional/behavioral aspects, and then using those differentiating aspects to classify the phenomenon(s).

> There is no fine line between globular clusters and dwarf galaxies

Perhaps you are right.

Globulars typically are much lower mass than galaxies, typically spherical, have much higher star density than typical galaxies and are thought to be formed in the evolution of a parent galaxy.

They talked about observing the motion of stars around the black hole core. What they're actually talking about is measuring the doppler effect to light from both sides of the high mass object. On one side the light will be shifted to red as stars hurl away from the direction of the Earth , on the other side the light is shifted towards blue as the objects are approaching us. This is done with a spectrograph.

M13 the great cluster in the constellation of Hercules is quite a sight to behold by eye in my telescope. Omega Centauri would put it to shame! I added color to my M13 image:
