A Dying Giant 2,500,000,000 Times the Volume of the Sun

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.

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

[samsschool]

I am so glad you guys are making videos again

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..

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).

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.

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

[TheLastStarfighter]

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 🪐

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

[koharumi]

Haven't heard of this star before.

[falconcarwash]

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

[Jay-cnjs]

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

[alexandrabyrd]

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

[dennistafeltennis]

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

[yesitssarahbby]

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

[papantro]

Amazing video! Red Giants are so satisfying for some reason

[francenjensen]

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

[beatrixhusband]

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

[quackbullgaming]

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

[low-phas]

One of your best yet!
Keep it up mate!
