@neildegrassetyson: Do stars truly die if we're made of them, and they're made of us? ✨ High-mass stars spend their lives in a beautiful dance, fusing light atoms into heavier elements to hold themselves up against gravity. But when they hit iron, the music stops,the core collapses and this triggers a catastrophic explosion. In the Stars final breath, they scatter carbon, nitrogen, and oxygen across the galaxy. We aren’t just poetically stardust, we are literally stardust. #space #Astronomy #startalk #universe #cosmos

So we’ll be around forever

Ashti Hayder :

Okay Big Bang; but where did that even came from? Where did a most initial thing start from? 🤯

Debra Starr58 :

I could listen to this guy talk FOREVER. 💙

Allison Carter :

Which way is up in space? Like when we study it do they consider one direction up or down or vice versa?

Ophelia :

My ADHD brain says “huh”? LOL

IngloriusBitchz :

Conscious star dust. We are the universe, it's just so wild.

Æther :

It makes me wonder if this invincible property of iron is the only way we could live and observe the universe from an industrial age of civilization. It seems like if it could be fused then someone would have caused a nuclear explosion in an iron forge. If that occurred, we could never developed iron molding or casting to create modern civilization. If there were universes with different laws of physics, a Drake Equation including universal laws amongst different types of universes would have to possess that principle to have modern civilization as we know it. We don’t even know what that principle even is.

I watch star talk every night. I'm a hairstylist at a country club and it makes for great conversations. Plus my comfort show✨

rqmzta :

💖 くうこ 🦊 :

I can't be the only one laughing at "astronomically" high temperatures

Theodore :

Imagine being able to harness the energy of any star or planet in the universe.

Lefty Blue :

Nell I have solved why light can't escape s black hole

treefuichi :

Im pretty squishy so we gotta rephrase that dust claim.

☕️🐦‍⬛The Atomic Girl🐦‍⬛☕️ :

Nessa_Marie :

This is sooo cool

Ks :

Someone could’ve came from the same star as another person

Casey Parsons :

John ruskin (victorian writer) wrote a nice essay in praise of iron and how gold is dead and “should be trodden underfoot”, he would have loved to add this fact in. It was a poetic prose kind of essay, how iron is alive and in our blood, used for tools and thus more important than collecting gold to be “rich”.

:

Was it you who said that we are forged in the hearts of stars? The statement was beautiful...and accurate.

Ann :

My mother always told us we were star dust.

percyhabsloverjrp :

it's like reverse chemistry
