How Do Stars Die? | Neil deGrasse Tyson Explains...

What is happening in the nucleus of stars? Neil deGrasse Tyson and comedian Chuck Nice break down how thermonuclear fusion happens in the center of stars and how it eventually leads to supernova.

At what point do fission and fusion meet? Learn about thermonuclear fusion on the inside of stars and how it leads to star death. Discover how stars hold themselves up from gravitational collapse and what causes supernovae. Find out what went into creating the elements within us and why we are all stardust.

Chuck is amazingly poetic in his way of describing his understanding of what Neil has just explained. These two are amazing communicators.

“We are not just poetically Stardust, we are literally Stardust.”

- Neil deGrasse Tyson

This is easily one of the best videos in YouTube’s history ❤️🙏

I love how Chucks face lights up when he grasps the concept Niel is laying down.

[VirajBaraskar]

"Not only are we alive in the universe, but the universe is alive within us." I felt like hugging the universe and thanking it for the wonderful gift of life we have. Wow!!! Just made my day...

Stellar example of why StarTalk is SUCH a good program. Fantastic content. Very well presented. Can't help but love the enthusiasm of both Neil and Chuck.
Hard to think of someone who wouldn't benefit from watching these with an open mind. Viewership should be SO much higher.

[Mako]

Pure scientific, witty poetry by Neil and Chuck. Bravo!!!

[LtNduati]

This is one of those things you can learn and understand, and still be just as amazed that it's true like you had never heard it before.

[miguelcarrera]

One of the best explainers I’ve seen. I truly enjoyed every second of this. Thank you.

[SweDennis]

This channel never ceases to amaze me. Although I've known of the physics of iron and fusion for a long time, Listening to Neil and Chuck still brings some new feelings and emotions to the table that I didn't have before. Just wonderful. <3

[Ashystar]

Iron pulls off its mask and says "ha-ha! It's me, absorpt-ion"
That did it for me😂 I love Mr Chuck & Mr Neil so much.
They make me feel like I'm learning along instead of being lectured 👍👍

[AnalogX]

Thanks Neil and Chuck for another great episode :)

[masterofnone]

Sure hope Chuck and Neil never break up. No one could do it better than this duo.
Neil teaching & Chuck learning with humor is what’s able to hold to the attention span of their like minded audience.
✌️❤️.

Just bought two of your books dr.Neil and they were signed gotta say I loved the natural history museum

[Sileonex]

Often times I fully understand the topics of these wonderful videos... But today I actually learned something new... Thank you

[Masmikh]

I cried in awe when Dr Tyson reached the Supernova part climax. What a beautiful journey for the start.

[MrVvrfly]

Love every single minute of this conversation. What a simple explanation and perhaps the best way to understand US in spiritual terms. Thank you Neil. Chuck you must know it is difficult to keep things together without your wits. I am so glad you both are together.

[Periodic-Milk]

I wish this came out a week earlier I just had a chemistry test on half of what they talked about.

[gabrielh.]

Nice video and explanation ✌️👍. One question: If star’s only fuse until they make iron and then explode into super novas, How are heavier elements created in space? Thanks

[MrZeek]

Supernovas and the creation of elements was one of the first discussions that inspired my love of space way back when. Thank you for rekindling that love StarTalk!!!

Yesterday I went to your show, “an astrophysicist at the movies 2” and I loved it. Very funny and was an excellent merge of pop culture and science, so thank you.
