A dying star enjoying the last moments of its life… A scarlet ball of white-hot plasma, whose prominences lance through cold vacuum in its agony… Two potent powers are at struggle in its depths. They now force the star to expand to dozens of times its size, then make it shrink again, only to flare up with new energy. One of these transformations is going to be the last one, but no one can foretell the exact instance with any certainty. This epic sight could be enjoyed by a space traveller approaching CW Leonis - a pulsating red giant which has been thrashing in a death agony for thousands of years.

Very

[@xanthippeli]

I get it 💀

[@information365.]

nice topic

[@shahanazpervinshati2136]

Thanks Kosmo.I was waiting for the episode.Recently I have interest on a topic "A journey to the traingulam galaxy"and now I am waiting for this one.I hope that I will see it from Kosmo in some weeks.

[@dotdashdotdash]

Thanks Kosmo

[@patrickmchargue7122]

Good walk-through of this star's evolution. Thank you.

[@baileypanama]

There’s no star evolution at all, they have never seen a star form, it’s all assumptions and speculations. This star is not dying at all, it’s the way God designed it to be and since science can’t explain how a star that Massive can expand and shrink like that, they want to make up stuff and say the star is dying when it’s not.

[@animalbird9436]

I hope you managed to get ye tongue back out.😱❤️😁

[@samsschool3639]

I am so glad you guys are making videos again

[@jeremysart]

It's insane that something can be so enormous. The Earth is literally microscopic next to it. Then we ourselves are like entire universes compared to the biological machines that make up our genetic material. And that genetic material is an entire universe next to subatomic particles... and this enormous star is microscopic next to the entire disc of our galaxy and.. *AHHHHH!!!*

[@poochiedaichell6646]

Madness I tell you lol

[@jeremysart]

@@poochiedaichell6646 seriously! 😂😅

[@isseabdirahmanweheliye9010]

And knowing despite how far spaces we can observe it will still be infinity times less then what is really out there 🤯

[@PrivateEyeYiYi]

I never worry about the scale of the universe. Sure there’s bigger and smaller stuff. But there’s nothing else like human intellect that we know of.

[@dancarpentieri7762]

That's what she said

[@Nefertiti0403]

My daughter named her cat Cosmo

[@darrellsaewhat50]

Just imagine millions and millions of years from now, if we don’t blow ourselves out of extinction. Our distant homosapien relatives whom succeeded in colonizing a nearby solar system, look up into the sky to study a dying star. That star would be non other than, a dying Sun (our current star).

[@nosuchthing8]

Or we could move the earth. Or populate pluto.

[@bryanbressem5026]

Sorry to burst your bubble but the human race will never reach even the closest galaxy from here, and nobody is coming here, distances are too vast for anything but pipe dreams, keep smoking, fools...

[@tristanholland6445]

We won't last 5 billion years.

[@hectorgrande8000]

We wouldn’t be homosapiens anymore. We will evolve into something unrecognizable by then.

[@TheOnlyKontrol]

Who’s to say it won’t be more recent

[@TheLastStarfighter77]

Thanks Kosmo, I find hyper Giant's and similar Star's fascinating especially Stephenson 2-18 and UY Scuti, it's mind boggling just how much energy these Star's give of in their very short lifetime's. Thanks for another great video Kosmo 🪐

[@thomaslechner1622]

Colliding giant black holes can give of more energy in 500milliseconds (in the form of grav. waves) than hyper giants in their total (short?) life of millions of years.

[@rbl4641]

This has the best solar simluations of being on the star that I have seen. Great job!!

[@falconcarwash435]

Ace job on the visuals! Very pleasant to follow the audio along to them.

[@ruperterskin2117]

Thanks for sharing.

[@alexandrabyrd3875]

I love all the effort you put into your videos! It's amazing! Great job Kosmo! 💜

[@metalthrashingai2238]

The fact something so massive and menacing is so close to us scares me. I mean, the sun is literally a lighter compared to it.

[@Shaz416]

The universe never fails to amaze me and leave me absolutely speechless. #humbled

[@Android_Warrior]

(Isaiah 40:25, 26) 25 “To whom can you liken me to make me his equal?” says the Holy One. 26 “Lift up your eyes to heaven and see. Who has created these things? It is the One who brings out their army by number; He calls them all by name. Because of his vast dynamic energy and his awe-inspiring power, Not one of them is missing.

[@Mr.Deleterious]

Awesome, detailed post. As usual! Thanks for sharing. 🤘🏻🤘🏻

[@yesitssarahbby17]

Idk why but 3:35 creeped me the hell out, it just looks so weird, i literally feel triggered 😂

[@quackbullgaming5599]

best channel ever i just hope you guys would upload these fantastic videos more often

[@phaslow4393]

One of your best yet! Keep it up mate!

[@kirbymarchbarcena]

Watching this star is astonishing

[@sirspectacular2428]

Amazing video! Red Giants are so satisfying for some reason

[@janetoney4714]

Thank you Kosmo!

[@Jay-cn3js]

I like to believe Stars don't really die. Red dwarfs, Black dwarfs, Quasars, Neutron star, Magnatars, Black holes all continue on forever really.

[@behnoodbehnood-oi7jt]

Thanks alot to the kosmo team. It was spectacular with lots of wonderful information. I learnt alot

[@koharumi1]

Haven't heard of this star before.

[@TwoBs]

Just wait until you learn about all the millions more out there that we’ve yet to discover/hear about.

[@animalbird9436]

You probably havnt heard ov the other trillion trillion stars either...or is your head the size ov one hahaha🤣🤣🤣

[@BeckBeckGo]

Heh ok. I’m not a geneticist. There are genes I’ve never heard of before. Weird.

[@irene8066]

captivating! thanks for sharing this knowledge with us, Kosmo!

[@Rafaga777]

Great video. Thanks a lot for posting.

[@patricksullivan653]

Just makes my heart ache,beautiful.

[@chriz97]

Excellent graphics and talk.. 👏👏

[@razzikhan1980]

What a beautiful channel and what a beautiful videos regarding cosmos. Awesome 👌🏼 👏🏼 👍🏻

[@dennistafeltennis1190]

A star that made us all. We are all made of Star dust.

[@francenjensen608]

Billy Connolly once said our entire cosmos probably exists within a chair leg of another bigger universe.

[@cojaysea]

There is a theory that Earth and sun and galaxy and all the known universes are only a dust mote on some policeman's uniform in some gigantic superworld. Couldn't we be under some supermicroscope, right now?

[@Tails_Trades]

What a beautiful universe we have 🌌

[@balkrishanaggarwal584]

This is mind-boggling!!! Amazing!

[@IsraelSocial]

Omg graphics are insane! Great worki

[@marcelosoutocamiou9363]

From Uruguay. thanks for another great video Kosmo

[@adamant262]

Great video!

[@LionelLiftsVegas]

Very entertaining as always!!

[@poppedweasel]

Simply awesome. Awesome presentation, awesome subject, awesome visuals and sound effects. You're coming along well, Kosmo.

[@ashishcodanda6572]

👍👌🙏 Excellent video...thank you Kosmo

[@beatrixhusband]

this is to show us how small creatures we are in the universe

[@kannagottipati6272]

Love the background music in the intro. Sounded like a high action battle scene score from bahubali.

[@capiecapie1]

Thanks

[@mlez7197]

even colossal monsters full of energy die...this is extraordinary

[@badmonkey2222]

I tried to find the star a couple times but I could never locate it, thanks for this..

[@scott5261]

Great job explaining the end of a stars life

[@lamminlunchongloi4317]

Like this walkthrough 👏👏👏 want some more 🤩🌄🤩

[@ameliadiaz8040]

You mean CW Leonis will end as a white dwarf star and then an invisible black one, just like our sun?

[@guillermoandresromano7632]

Fantastic!

[@mikesmicroworlds4566]

Man someone needs to thank the camera guy. He must be getting tired out there haha Epic video as always guys 🙂

[@afeezjimoh8263]

I love the intro of this video

[@Nefertiti0403]

Oh Yes. I did Watch This! Loved it

[@BradyLangaigne]

Yes Kosmo. Thanks for taking the time to put out another video. Hope you are doing well. Your voice is little bit off. Will enjoy the video

[@ministryoftruth8523]

Amazing graphics.

[@freddyjosereginomontalvo4667]

Awesome channel with awesome content as always 🌍💯🤗💖

[@_xXx_YT]

Beautiful.

[@lilysceesawjeanmoonlight]

I absolutely luved this doco !¡!¡! 💫☄️✨💫☄️💫 At the end of every storm a fresh Rays ☀️ of 🕯️light🕯️

[@hevysmokerX]

An explosive video!

[@nogod7184]

Roughly same size with Betelgeuse. And they are perhaps in the same stage in their lives.

[@ugoeze7360]

All praise to the cameraman.

[@jiujiu]

You're saying it's "thrashing in a death agony", but really it just turned 40

[@olgabenavidez447]

It's beautiful but it's creepy at the same time

[@sarfrazahmedc]

How the Divine operates.. Majesterial

[@kenhammscousin4716]

Makes the planets and us ourselves feel so small. I wonder if there could be life on gigantic planets where everyone evolved to be huge

[@maryann2628]

Gravity is the problem they will small so small planets will make big creatures

[@LEOFADS]

Great video

[@ryanmcwilliams8784]

Thanks for the update didn’t get any notification glad I saw the extra post !

[@MrEnjoivolcom1]

Same will happen to our sun. Swelling up, only to deflate and swell, expanding for a second time before going nova.

[@happi-bollox]

I think the general view is that our sun is too small to go nova..it would need to be 7-8 times bigger..

[@MrEnjoivolcom1]

@@happi-bollox You are correct, and I know it cannot go nova and will shrink to a white dwarf. Really dunno why I typed that. Possibly caught up in the visually exploding moment.

[@douginorlando6260]

Perfect candidate for the JWST.

[@roypruysvdhoeven1855]

UNBELIEVABLE SIZES OF STARS ! THESE GIANT STARS SHOULD BE APPEARING NORMAL IN THE BEGINNING OF THE BIG BANG..NOW AFTER 13.8 BILLIONS OF YEAR THEY ARE RARELY....

[@Roykalburgi]

I'm curious to watch channel like #Kosmo, in the next video I would like to see Variable Stars, pls make a video on that.

[@gdelacerda]

Good! 🔥

[@basinaveerabhaskar7663]

Oh lovely space My wife is pregnant please blessing to my wife for healthy strong baby boy

[@josephpacchetti5997]

Interesting Video, Thanks Kosmo. 👍

[@peterdo5047]

God I love science -oxymoronic, I know 🤣

[@blackninja738]

Very beautiful information but very deadly climate

[@awaismahmood2452]

CW is class work nd HW is home work 😂

[@DerekMitchell]

Could the missing Planet X in our solar system be a black dwarf from an earlier duplex system?

[@dilip_s]

Now this thing will turn into a supermassive blackhole right

[@illumencouk]

FYI - 'CW leonis' is an anagram of 'We Colonise'.

[@sickoftheshit]

Wow! The life and death of stars intrigues me. Thank you once again for your most interesting videos. Excellent quality videos, I might add.

[@spheise252]

Nice video

[@matthewjswider]

Why aren’t there more of these observable?

[@dannymack1196]

I see a swan 🦢 at 0:37

[@justaguy4real]

3:50 insufficient? Incredible they know all this stuff thru study

[@Narancsmagful]

so, it's basically a low density red giant. i kinda missed the part why this special

[@vcastik]

That is monster eats everything around, so gravity will reaping it to dust!

[@billyratchet6463]

This seems nice

[@junaid2773]

The intro music reminded me somewhat of doctor strange 2's trailer theme.

[@blablableh724]

Stars do not feel agony, they have no feelings as they are not alive.

[@adrianaa3059]

2000 C ? almost twice as hot as a *regular candle* it is true! go check it! a regular candle flame burns at over 1000 C!

[@maryann2628]

The sun is even hotter at 5780 C

[@EcoCentrist]

stars be crazy, yo

[@woody5109]

And we wonder why advanced life never stops in to say hi, we are pretty insignificant.

[@Ryan98063]

I am eagerly waiting for Betelgeuse to go

[@explorer1968]

Another star that is going to the recycling bin of the Universe...

[@Bearcat870]

This star is so big ….. earth 🌏 wouldn’t exist.

[@papadocsamedi2544]

Great vid, but for me the background music was too loud

[@SpaceScholar]

This is educational... I also covered some topics on space recently. Great video, Kosmo!

[@wizzardofpaws2420]

Why don't I hear "KOSMO" in the intro? That's awesome and I miss it.

[@illylilly8491]

Stars are truly amazing things. Space itself is an endless fascination.

[@medina__anidem]

We are whooville speck of dust😂

[@michaelwachendorf2096]

Why wouldn't this sun turn into a black hole? It's got the mass

[@droach5241]

I thought this was going to be Betelgeuse..
