The Universe’s Strongest Magnets, How Magnetars Form

ranjeet singh

What happens when a massive star dies? 🌌 Sometimes, it doesn’t just collapse — it becomes the most magnetic object in the entire universe: a magnetar.  In this short, realistic simulation, you’ll see: ⚡ How a giant star burns through its fuel and collapses in a supernova explosion 🌀 How a neutron star forms — a city-sized object heavier than the Sun 💥 And how extreme spin and turbulence turn it into a magnetar with magnetic fields trillions of times stronger than Earth’s!  This is not animation — it’s based on real astrophysics. A visual journey into the science behind the universe’s most powerful stars. #Magnetar #NeutronStar #Astrophysics #Space #ScienceExplained #SpaceFacts #SpaceDiscovery #Universe #Physics #ScienceShorts #KnowledgeLab #SpaceSimulation #Cosmos #StarFormation #BlackHole #astronomy

00:00What if I told you there are stars out there with magnetic fields so powerful

00:04they could erase every credit card on earth from a thousand kilometers away.

00:09These aren't black holes, they're called magnetars and they hold the strongest magnetic fields in the entire universe.

00:15But how are they formed? Let's see what really happens step by step.

00:18It all begins with a giant star, much bigger than our sun, sometimes 10 to 30 times heavier.

00:24In its core, nuclear fusion converts hydrogen into helium,

00:28releasing huge amounts of energy that pushes outward.

00:30Gravity pulls inward, fusion pushes outward and this balance keeps the star stable.

00:35But that balance doesn't last forever.

00:37When the star runs out of fuel, fusion stops, gravity wins and the core collapses at enormous speed.

00:43The outer layers explode outward, a supernova.

00:46For a few seconds, the star shines brighter than an entire galaxy.

00:49What's left is a neutron star, only about 20 kilometers wide but heavier than our entire sun.

00:54If you could scoop out a teaspoon of it, it would weigh a billion tons.

00:58Inside, protons and electrons are crushed together to form neutrons, creating one of the densest materials in the universe.

01:04But some neutron stars are born spinning hundreds of times per second and that changes everything.

01:09The rapid rotation and turbulence in the liquid core amplify its magnetic field, a trillion times stronger than Earth's.

01:15This is how a magnetar is born.

01:16But magnetars are unstable.

01:18Their magnetic fields are so strong, they can twist and crack their crust.

01:22When this happens, they release massive bursts of X-rays and gamma rays, called magnetar flares.

01:27A single flare can release more energy in one second than our sun produces in 100,000 years.

01:32So next time you look at the night sky, remember, somewhere out there, among billions of stars,

01:37a few tiny city-sized objects spin silently with unimaginable magnetic power.

01:42That's how a magnetar is born, the universe's ultimate magnetic monster.

01:47That then can base the transporter comes with over ten.

01:51And it truly has a cluster of investir and devil auricul 여기서 to prepare like Ryan or

01:54US- Les Rojas, which is the evolution That vists into that makes any mikrograms,

01:56can be seen from that prototypical USD in certain times as well.

01:57Theibile took place is in the atmosphere as well.

01:58I mean, you will hear that as well asmens might happen with dolphins and by step by

02:02plan animals.

02:03You see the dangers of its glow that we should post them together just dramatically.

02:08In this particular, we'll only be left with flea class square but not to reference certain

02:11movements and back into that location you have.

02:11In this course I'm gonna take about 10 seconds here.
