Stars dot the night sky, and fill our galaxy. But how much do we actually know about stars? Where did they come from? Are there different types? What will happen to them eventually? This will be a short series of videos, covering the life cycle of stars, starting today with their formation, the next episode will be the main sequence of stars, and the last episode will be what happens to stars when they die.

I live in South Africa and can confirm the stars are as good as ever if you get away from the city, in case anyone was wondering...
No one cares about South Africa, or Africa for that matter. let it all collapse beyond repair.
I was in South Africa in game reserve far away from any city. The stars were incredible. Just seeing the milky way in all it's glory was something i'll never forget.
I was wondering. Thank you.
that's why I am laughing at the dudes having telescope at home in the city, they're the worst place for stargazing....
@@jchen8792 not so if you know what youre doing. you can see 9th to 10th magnitude stars thru a 400mm telescope in the city .

this aged well
You can exhale now
let’s gooo
Is it just me, or does Alex's voice always sound like he has a smile on his face? I'm not even sure how I can describe it, but it just always sounds like it to me.
That’s called the smiling voice
Well, you see, when a mommy star and a daddy star love each other very much...
Then a kiddo star is born...
🤣🤣🤣
More like when one or more stars die...
Stars come from Uranus
N then there was light. And it was goooooood
(Chcka chcka wuh-kah chcka chck-a ch beeeww) 👉👌
K maybe the sign language was a little much
I know exactly the sort of sight you're talking about when things are clear and away from light pollution. And yes, it's freakin' awesome.
Wow why such little views? I get excited to see your videos. I hope you remain active i genuinely enjoy anything you put out especially space related. Well anyway i do sincerely hope you grow as a channel and make more videos as we learn about what goes on beyond us.
I ALWAYS look forward to seeing your videos. Thank you.
Man I have become such huge fan of your videos.... IAM LIKE ON BINGE WATCH OF THESE....
TheUseFul same
iv just found this channel, this man is a boss, videos are great and all very informative.
Me too! Lol
Mee too!
Awesome... Life is actually beautiful...
Man I've missed your videos, great job!
I just dicovered your channel, and as a huge space fan, i must say your work is absolutely brillant ! Thank you for such quality in your explanations and astonishing images !
Wow. Another amazing video. Wish I subscribed sooner! I would love it if you made more videos. I can't get enough!
Another awesome video. Glad you were able to squeeze one into your schedule!
New video 😮 Great Job! 😁
Great video, cant wait until the next one!
Great video as always - and thanks for the link to the website.
Marvellous video! And your explanations are clear and brilliant. Thank you!
I'm really happy for find this channel :) Thanks for every shared videos. I'll be with you are..
Thought I'd give it a couple of views before sayin' ......thanx Alex , for another well done video , already lookin' forward to the next one
We were waiting for you!
I loved the video, just like everything you post
Really great job on this, Alex.
Probably the best video on this topic... Just sayin'
I am subsribing and you keep 'em comming
So good! Thank you so well done and clearly explained 🤙🏻
Teriffic Alex, great job as always.
Thankyou... These would be a lot of work to produce.
Well done! And, I appreciate, you ended the video humbly. Saying, "although, i spoke matter-of-factly, this is only a theroy of how stars are born."
Congratulations for your channel. You talk about things I never heard before.

Who cares?
One was undoubtedly from the infamous Ken Ham, a guy who claims that the universe is only 6,000 years old, but we can still see things millions of light years away because the speed of light was at one time infinite -- Slowing it down to 300,000 km per sec. was one of the things God did in his wrath after "The Fall". (No joke -- This is really what he argues!)
Those bastards
@@stargazer8in174 fuck up bitch boy
I dont recommend their videos 😆
I appreciate the work you do! Thank you!
Great video. Looks fantastic!
When a papa star and a mama star Love each other very much...
Thank you for the video! I was feeling really stupid wondering how stars were formed, since this was taught in elementary school. I was SO relieved that we don't know for certain and what we're taught are just theories!
perfect Video. Great Job. Nice pictures. Cheers for uploading. bye bye Toni
One of the best channels. You need more subscribers.
"The James Webb Telescope, due to be launched in 2019"
Any day now, right?
Let me join in the praise. You do a great job. I'd say you and David Butler are my choice for cosmological videos.
Sure! I'll rewatch this one!! Your videos are awesome!
You are the creative scientist I “know”. Creative way of presenting the subject. I love it.
Fabulous and riveting! Thank you!
Thank you Alex for creating this video, I finally actually understand star formation 🙏🙌
Wow! 0.08 seems far to sparse but that could be enough to make a star! Really stretches the mind up into the infinite & down into the infinitesimal thinking about stars!
Dont know if you read old vids newer comments, but i never went to south africa, tho im dutch i visited your own homecountry to visit my friend who just married a girl from there. That allready blew my mind, cant wait till next holiday when i will visit africa, not south but just a lil bit more northern, cant wait to just see the sky in awe
Please make more videos,they are sooo good.I am particularly interested in Mars and the gas giants moons.
Nicely done. Good video
It was rendered beatifull and learnfull. A very nice video!
Great vid, makes me want to go star gazing again.
Great Video, Thanks!.
Greetings from Chile.
Damn I love these videos. So calming and relaxing
This is my favourite space Chanel it is so cool I watch it ever day
Very informative. This is a great, easy to understand site. I always enjoy watching and learning
As always, AWESOME video with lots of great information! This channel has turned my 5 year old son into a "space freak" everyone is amazed at how much he knows about space! Lol
Great video! :)
I spent two years in West Africa, about 150 miles from the coast. Night skies were brilliant with stars.
I love all your videos one day maybe my brain will b that big I certainly learn alot from each one thanks again Alex
I have been fortunate enough to have seen the milky way in several European countries and it was gorgeous. However, light pollution still made it rather faint. I'd love to go to a remote place in the southern hemisphere like you did and get a proper view. I have this on my bucket list together with seeing the aurora borealis or australis. At least I got to see Hale-Bopp in '97 and the full solar eclipse in '99 which was absolutely spectacular.
You think you could make a video on centaurs? Such as 7066 Nessus? I keep hearing about them but I’m unable to find anything on them. Great content, as always! Thanks!
Wish I was born 2000 years in the future imagine what we would know by then.
Perhaps we’ll all know that one day! Imagine if the creator of all these laws of life and existence enables us, one day, all to travel to any part of existence we want! Life is SO extraordinary that I can easily imagine that one day, even after our body ‘dies’ we could still retain our essence of individuality and memories and be given ability to visit any other place or time which has existed!!! Just in this present moment we’re witnessing HUGE complexity and consciousness all around and inside us.
Now don’t tell me it’s all random, by chance and is just a dead arrangement with no intelligence behind it all. No way, in my view. But the Creator or supreme Being, which we may all be part of, may want to give us free will etc etc to enjoy or be punished for our degree of collaboration with the amazing created/creating universe as it is being rolled out - right now.
Just a thought! I’d like anyone who agrees to reply ‘yay-ok’ if they’ve had similar impressions. For me it’s all coming together in my present moment understanding. Hey, those understanding this, let’s form a new, awe-struck group of highly caring humans who feel something like LOVE for the creation and each other. Personally I want to use my respect for existence to CARE for our Earth and our children’s future.
@@MyaPuppets There is no creator. And it's not random. It's governed by physics. None of the natural processes are random, but they don't need a creator or intelligence to exist.
This was an amazing episode...clouds in space just baffle me.
Could you do a "what if" episode: "what if Jupiter was a sun"?
@Astrum Please do a video series about black holes, it's creation and effects in the galaxies and the universe. Thank you
So Beautiful!!
Will you make more vids on stars?
Great video
Beuttifull please more of this and specially Titen moon
@13:18 This is a big advantage of the James Webb Space telescope ... *due to be launched in 2019*
*Oh, well*
Here in South Africa I agree how gorgeous some places are for stargazing
👍 thank you man.
New sub 🤗
Thank you, Alex! 📡
Really enjoy your videos, Thanks for making them.
It seems strange though that the theoretical impetuous for a star to form is other preexisting dying stars or gravity waves from pre-existing galaxies, and that while we observe the death of stars, we have not actually seen the birth of any, especially given the vastness of the universe.
Like I mentioned, hopefully that will change with the James Webb Telescope. It is being able to see through the dust that is the problem.
saw this article, which relates the lowly Scallop to the James Web telescope, and though you might enjoy.

I'm so happy for those molecules that after all those billions of years they get excited at last!
Woooooh new video
i clicked for thumbnail, a horse running towards the setting sun... majestic
👍 wow
A more important question is this, where did all the matter in the universe come from? Do you really believe it was all contained is a tiny dot the size of a flea?
a master clas awesome im very thankfully iluminated
Oh an Astrum upload! Time to watch the video with ashtray and rum. 😂😂😂
Thanks!
So cool...
Always enjoy your videos. Your voice conveys your passion and your words make it accessible for a broad audience to understand.
Didn't know that the gravity increases with a temperature.
The Webb telescope was recently launched, so soon we could see some protostars.
Brilliant, the old age question the immovable force against the irresistible object.
Where does star comes from? When a mommy star and daddy star, forgots to put on something.... A baby star borns!! Yayyy
Thumbnail was cool, looked like a giant vein
Thanks
This is like the fluid action of the density of everything in the universe.
Governed by the laws of gravity and physics and kept in check by laws of quantum mechanics.
And I'm only qualified as a boiler maker welder. With a passion for the stars
Silly question, could we use nukes in the dust cloud to act as triggers? Just how big do the shock waves in the dust clouds have to be to trigger star formation ?
I'd imagine very big... and remember this happens over hundreds of thousands to millions of years, so even if it did trigger star formation, you likely wouldn't see the end result :)
Hi Astrum Im interested in learning more about density waves mentioned midway here. I've looked through your channel titles and can't find the video though, could you link it up please?
One video I mention density waves is about halfway through this video! th-cam.com/video/8D6UWHZ_HYs/w-d-xo.html
Where I live in North Carolina is probably the worst place there is for seeing stars. At night ud be lucky to see about 30 stars
I wonder if some day the interstellar medium will be used to help humans travel between stars.
I'm starting to think in stars like living beings,as if they were some kind of inorganic gigantic cells,whose ashes after death form new things,like here on Earth,and they form communities to creater larger beings,galaxies. After all maybe it was the Sun itself that created life after sending UV rays towards amino acids in the early sea,stars themselves are formed when UV from a quasar hits their cradle clauds.
Is this the real color of the Stars or just computer generated?
Hi from South Africa, nearly 4 years later😅
An excellent video. Just a couple of points, you say molecule but the image says particle. The two terms aren't interchangeable, molecules are made from particles. Also the plural of nebula is nebulae, pronounced neb-you-lee. Other than that I found the video fascinating, especially the simulations.
Good points! Thanks
Supercluster is a term used for galaxies, not necessarily stars
One thing I've wondered about star formation has to do with massive stars being formed. How do they acquire so much mass, I thought that once a stars fusion reaction is initiated the surrounding dust and gas cloud were dispersed away from the star from the solar wind and energy output. So the massive amounts of gas would have to be present before the fusion reactions begin or else the star cannot keep acquiring mass after the fact Right? I would guess that there would have to be special circumstances like a supernova along with many other factors to compress those amounts of gas to create the largest stars.
Stars centers are from Counterspace.
Still waiting for the Jw telescope to be launched at the end of next year :D
Did I miss something? It sounded like all these scenarios require the existence of stars to trigger the process in the models he described. Where did the first stars come from?
This is the real story of A star is born
