What Are Neutron Stars?

Neutron stars form when a massive star runs out of fuel and collapses. They are basically the collapsed, burnt-out cores of dead stars. Please, watch the video to learn more about Neutron stars.

CORRECTION: A star needs to have at least 8 times the mass of the Sun in order to become a neutron star.

[@hanksauri]

Some extra facts: To form a neutron star, a star needs to have 8-20 times the mass of the sun Neutron stars are 1.4-2.8 times the mass of the sun, packed in a ball 15-25 km in diameter Neutron stars have crust made of iron nuclei, so dense that it's 10 billion times stronger than steel, surrounding a sea of neutrons Most neutron stars have magnetic fields 1 billion times stronger than Earth's Some OP neutron stars have magnetic fields up to 1 million times stronger than that of a normal neutron star, and are called magnetars The powerful magnetic field of a neutron star acts like a particle accelerator, blasting out twin beams of visible light, radio waves, and X-rays from the magnetic poles These beams, combined with the rapid rotation, sweep around space like the beams of a lighthouse, creating pulses of radiation at a consistent rate, and neutron stars that do this are called pulsars When neutron stars collide, they explode in a massive explosion called a kilonova, producing lots of heavy elements, the gold alone in one kilonova can be equivalent to 100 Earth masses

Density of Cosmoknowledge content is more than neutron star

[@Cosmoknowledge]

That was a good one! 😄

[@ZappaBlues]

When the mass of the star left over after from a supernova is from 1 to 3 times that the mass of the sun you have a neutron star. After our sun dies and it sheds the outer layers, it will be a white dwarf.

The Best part about THIS spectacular KZbin channel and its wonderful and hardworking OWNER is that it always gives value to the comments left by the viewers😊👌👍....this is an amazing thing😃....i really love this 😍😍💖.....🙌👏i salute you for your hard work cuz i know its not so easy as it seems to be.....🤔🙄😤😩we can realise the pain while doing any project and spending so much time on studying and researching on it....its not good,its the best....JUST LOVE IT 😃🤩💖💕🙆‍♀️🎉🌹

[@Cosmoknowledge]

Wow! That's amazing to hear! We really appreciate it! We try to do our best. ✌

@@Cosmoknowledge I hope you make it to 100K, you're 3/4 the way there, you deserve it!

Great video, congrats on 0 dislikes

Hey, thank you! I appreciate that! ✌

[@awaiz1507]

whatever no you are on the feedspot , you are no.1 astronomy channel for me

[@Cosmoknowledge]

Haha, I appreciate it so much. Thank you for your positive energy!

[@alvinwins6249]

Geez! Neutron Stars is so bright it hurts my eyes and that's only in the computer screen.

[@Cosmoknowledge]

It's powerful, I know! 😄

[@pjaro77]

This is first video, where the extreme gravity and curving the light around neutron star is shown.

[@tangent123456]

Neutron stars are insanely epic !! Btw, a star has to have ATLEAST 8 times the mass of our sun to be able to undergo a supernova. The 1-3 masses fact you gave is the mass of the actual LEFT-OVER core, this is what becomes a neutron star :)

[@Cosmoknowledge]

You are right. Sorry for the mistake! I pinned a "correction notice" in the comments! Thank you!

[@tangent123456]

@@Cosmoknowledge Np! 😊

[@CinemaAgricultural]

I know a neutron star that goes by the name PSR J1748-2446ad and he is spinning so fast if you humans were to stand on his equator you wouldn't be cursed due to rotation speed making the gravity there less instance.

[@Cosmoknowledge]

True.

[@yogitakukreja2296]

This was really awesome and informative!! Thanks a ton

Oh, so glad you enjoyed it. Thank you! ✌

"Okay, I'm as fat at the should as I could." haha. Ask an odds maker what the likelyhood of shuffling a deck of cards back to consecutive suits, never mind any particular order. Never. Eliminating all other particles to leave only neutrons has to be one of the most ridiculous, cockamamie concepts ever dreamt up to cover the ignorance of theoretical physicists who couldnt explain a phenomenon . . . ever . . . except perhaps black holes. hahahaha!! And talking about it serjously no less!!! hahaha! "All your base are belong to us!"

[@HIK_48]

Please adopt the metric system already. Even the British who spawned the imperial system have seen the light..

[@colinbrown3170]

What if a magnatar gets a pulsar caught in it's orbit or collides ?

[@hanksauri]

They blow up?

[@colinbrown3170]

@@hanksauri that seems likely. I thought it would be a more energetic event because both have gamma radiation and high magnetic field.

[@hanksauri]

@@colinbrown3170 It is a cataclysmic explosion called a kilonova

[@colinbrown3170]

@@hanksauri shame we can't get closer and see it safely. It'd be interesting to witness.
