The life of a star

A white dwarf

White dwarfs are actually quite simple; after a star dies it usually creates a planetary nebula wich are basicaly the outermost layers of the star flying into the void. After that, the star gets compressed into a white ball smaller than the earth. This, is a white dwarf. white dwarfs are inactive wich makes them last much longer than other stars. But eventually they'll die, becoming a black dwarf, wich is a dead sphere of ions.

Black holes

When a supermassive star, like a, SUPER SUPER SUPERMASSIVE dies it will implode and after that it will have so much mass, in such little space, that that it's core will become a singularity: an infinitly small point of infinite mass. Now a black hole does NOT suck in things like a vaccum cleaner; it's gravity is concentrated into one small spot in space.

Neutron stars

A star nearly as massive as a black hole dies, and the core of the star gets crushed. particles like electrons and protons really dont wanna be near each other, but the pressure crushing the core is so strong that it not only makes electrons and protons touch, but they also fuse! This makes them into neutrons. But... the core isn't the only thing that gets crushed, the whole star gets crushed, it gets crushed so violently in fact, that it creates a supernova.

THX 4 ur attention!

if you liked my presentation and are interested in more stuff like this, check out Kurz Gesagt in youtube, they're were i got most of the info.

billions of years after a star is born, the star can no longer sustain itself, it collapses on it's own gravity. the outer layers expand and cool down. depending on the star's size one of three things will happen

A neutron star

A black hole

is born

A white dwarf

is born

Is born

Gravity pulls dust and hydrogen into a giant swirling vortex, which slowly heats up. After hundreds of thousands, of years the vortex is now a huge spinning disk bigger than the entire solar system.

Gravity crushes the center of the disk into a super massive and super dense ball of matter. Pressure builds up, until, huge jets of gas burst out of the center.

Gravity keeps sucking in hydrogen and dust particles wich crash into eachother generating more, and more, heat. In the next half a million years the young star gets smaller, brighter, and hotter. Temperatures at it's core reach aproximatley 990000 celsius, allowing fusion between the atoms wich realises huge amounts of energy. And eventually atoms begin to fuse together. And just like that a star is born

they exist
