The life cycle of a neutron star - David Lunney

About once every century, a massive star somewhere in our galaxy runs out of fuel. No longer able to produce sufficient energy to maintain its structure, it collapses under its own gravitational pressure and explodes in a supernova. The death of that star is the birth of a neutron star: one of the densest known objects in the universe. David Lunney explores what, exactly, a neutron star is.

I’m in awe of scientist seeing a flickering light light years away and then being able to describe the whole process from Earth.

It's more amazing that Einstein, after his death, was proved right even recently. That's some amazing accomplishment.

Can't we get permanent lessons of Ted-Ed in School 🏫

[paradox...]

Yup, I'm starting a band called *NUCLEAR PASTA*

LIGO and Virgo: What frequencies are you going to emit?
Colliding neutron stars: *YES*

This channel is extremely addicting. I'm supposed to be studying for my french exams but I cant stop watching.

[Skulltroxx]

I'm amazed by how much we humans have developed ourselves in trying to know about this universe...
But I'm mesmerized by how GIGANTIC this universe is, that we still have mucchhh to learn about! 😻

TED-ED you people are great...All the videos are so resourceful❤❤ Thanks for all these videos💖💖

I love all Ted ed videos, but I think this is my favourite. The narration was excellent and easy to comprehend, and the animation was spot-on. Beautiful!!!

[bubblesintheocean]

I love how the information is shown and told at the same time, and the animation is amazing too!!

4:00 Is he holding out his tongue!!?😂😂

My favourite Neutron is Jimmy, though I wouldn't call him a star.

Almost to the end of semester taking two astronomy classes of general theory and observations. Finals are coming out and I am here to expand further comprehension of the stellar life cycle. It is amazing to know how these clouds are formed outer space and I am glad to know all about it. But really wish me luck in passing the finals.

Incredibly difficult lesson to animate without making a bunch of errors and ending up with visual nonsense. Amazing job! You can tell that the expert (Lunney) had a ton of input. Congratulations TED-Ed team!

The recent researching method: multi-messager, has contributed a lot to the astrophysics field. So did the gravititional wave and the neutron stars, these are all significant discoveries which changed people's attitude toward the universe.

[chandrashekharsingh]

Ted ed is the best place to get information

[marlowekarl]

Stunning animation and a wonderful lesson as always!

I believe it collapses under its own intense gravity. Pressure is the countering force that stabilizes the star's shape (Gravity<...> Pressure). Informative video, I love it.
