Absolutely sensational, "B-V is the visible light which in turns tell us the outer layers temperature" such a simple statement and such deep meaning, love it!
Hi Brady, I really love deep sky videos very much, I look forward for each episode. For this I am wondering if you would consider make a longer format videos ~20-30 mins. I would like to learn more about astronomy and your videos do it so well. Cheers.
Brady, because of this channel, whenever I see the sun, I experience this nigh-indescribable feeling of awe and somewhat existential, astrological anxiety because I can't think of it as the 'sun' anymore, but a star, and how amazing it is how close we are to it--and of course how fragile and finite the solar system really is. Love this stuff. Makes me feel more alive than I ever have before. Knowledge isn't power, it's purpose and meaning, the real standard candle for human progress.
Perseus Arm Clusters are M36, M37, M38, M52 and the Red Star Cluster M103. Crab Nebula is also in Perseus Arm, these are likely the easiest objects to see from the 'outer rim' of Milky Way.
Brady could you do a video on Thorium again on Periodic Videos, but this time cover the new found interest in it as a fuel. Seems strange that we use uranium instead from what I've heard but maybe there is more to it.
I think it is a little bit oversimplified, but i guess the idea is, that the energy is distributed according to the Stefan-Boltzmann law (i hope i don't mix my laws up). So if you know the overall intensity ad the intensity of one frequency you can calculate the frequency with the maximum intensity and from that the Temperature... i hope that helps a little bit
I don't understand why you subtract the v-filter from the b-filter. It seems so arbitrary for getting an absolute measurement about the temperature of the star. He is saying you are getting "the" color and "the" temperature of the star. Can anyone explain the subtraction of filters please? Thanks!
Uhh... did someone forget to explain punctuation marks/digit separators to Mr. Trumpler? 1.3.26 seems a more rational/easier to interpret and compare than I3z.
Nyt Mare All it takes is a Google search to show you that observational Hertzsprung-Russell diagrams are typically called color-magnitude diagrams. As I am sure you are aware, there are multiple types of such diagrams, and the observational type are called color-magnitude diagrams by many an astronomer. Why does it matter to you what graphing interface an astronomer uses in a UA-cam video? I am always intrigued when a random UA-cam user calls into question a professional scientist's qualifications on the basis of something inconsequential. Prof. Norton is a well-known and well-regarded astrophysicist. Are you suggesting that he is not qualified to speak about M37 on the basis that he correctly refers to a color-magnitude diagram as... a color-magnitude diagram?
This cluster is "about four thousand lightyears away." The closest star is 4.3 lightyears away but it is only one star. How is distance assigned to a cluster or a nebula?

Just came here to say your videos are awesome and so is this Mike guy.

i love how mike speaks, hes so genuine!
Brady's vids are always insta-like for me. They never disappoint me, always something interesting.

Love that Trumpler guy. Such simple logic and method, and it worked
Haven't even watched the video yet. Already liked it.
Hope it fulfilled expectations! Cheers for the like!

Without going through all the videos and checking, I seem to remember videos on M37 already, quite a few of them actually. Aren't there any more?
Andy Norton would be a great narrator.
It's different every time.

You you imagine just being an unlucky planet orbiting one of the stars near the center of this cluster or another more compact one.. :3

i've always wondered if these star clusters are part of a galaxy or not.
How can they tell if there is a more distant massive star whose light is shining through the cluster but is not part of the cluster?
Which magnitude is plotted on y axis? Must be some broadband filter?
Beautiful mullet.

Was our solar system born out of a cluster like this, if so how many stars would of been with the sun when it came in to being?

That's what you get asking a scientist a quantifiable question without providing a unit of measurement, LOL.
You should have a show on the Science channel or Discovery channel or something.

ha, my fave gamespot reviewer commenting on my fave youtube channel ;). the nets are small.
We have a roman numeral, in this case a "one", an arabic numeral in this case it's another "one", and a letter, in this case an another "one"
They said a star cluster was interesting!
nice
cool :D
Soot, remember their direction...come on
I so want to buy a telescope right now...
Did you?

Less posh British suite guy and more merrifield
What kind of scientist uses excel for plots? And what astronomer calls a Hertzsprung-Russel diagram a "color-magnitude diagram"?
